Title: Boogity boogity boogity, let's go racing.
Post by: Ameritude on November 08, 2020, 03:10:55 PM
This is my 1978-79 kawasaki invader, that I picked up for a little less than 160 bucks. It has about 1850 miles and I'm going to be racing it next year in january. My vintage sled guy, has about 20 of these sleds sitting in his gravel driveway all under a tarp. I honestly picked this one because the seat is literally perfect and I believe its factory. The hood is pretty decent, the worst part on it is the paint cracking, it's all there structure wise. I thought ide bring you guys along with me on the journey of restoring/race prepping it. I plan to clean the exterior up and shine up the aluminum but leave the hood how it is. The engine is where its really gonna shine, its going to be immaculate and perfectly functional. Kinda a sleeper in my brain. Anyways, hope you guys enjoy

That's not the original seat.

A really nice original seat for a 78 Invader is very rare,  this one is aftermarket but looks real good.  It will be fun to follow your efforts with this sled.

Good Luck!!

Well of course, im preoccupied... I guess I gotta get the old scorpion back together before I get started on anouther project. I did however get the clutch, carbs and gas tank off the kawi. That blue sure does clean up nice. Anywhoo, better get back to work.

Side by side, crazy how much of a difference in size there is from 71 to 78 sleds
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Interceptor398 on November 17, 2020, 08:29:17 AM
They started out big and simple, then got smaller and now small is not a work that fits.

Got the engine out and completly disassemble, there's alot I probobly could have just left alone but to me, the best way to learn is to see and the only way for me to see how this thing works, is by disassembling it. There's a few rough spots such as a chip in the casting in the bottom half of the case (see in pictures) and a whole Lotta scraping in the bottom in-side of the case. What I believed to have happened is a piston let go for some reason and the chunks of it went down there and had a party. I did however talk to the guy I bought the sled from today and he told me that he had rebuilt it about 4 seasons before it was parked (about 11 years ago) with an entirely new bottom end and top end, how realistic this is, I dont really know.

I have seen worse.  Nothing that would make me think that it can't be reused.

Are the sealing flanges clean and flat?  I cannot tell if what i am seeing are scars or old sealant.

Its just stained, there's no deviation in the metal on those parts, it cleaned up just fine.

She's been broken in for me a little... (chain tensioners) luckily I can just flip em

Got the engine all done, looks pretty good if I do say so myself (don't worry the unfinished, flaking parts will be finished). Carbs are just on for mockup right now. It took me quite a bit longer than expected to finish it up because I broke a bolt off in one of the heads so I had to source a new head. Worked out though because I got two 79 heads for it for the great price of free.99.

This is a brake lever that I designed out of round aluminum stock, because I couldn't find anybody that made a curved brake lever for going left, for a sled with cable disk brakes. You can find them for juice brakes but not for cable. The picture is it wrapped up in electrical tape for just a little more grip and for looks. Here is a link to me describing it in more detail: https://youtu.be/fBt75fa0byM

Quick update. Races were canceled this year, but I'm still pushing to finish the sled (its a very lazy push). I did build this however, im getting rid of the original tank due to cracks and it leaking ( I know it could be fixed but I like the looks of a  smaller gas tank) plus if I ever want it back to stock for a trail ride, all the parts are still there, I just need a new tank. Please keep in mind, this is not a finished product, it will be much cleaner and the lines will all flow..

Post by: Ameritude on February 10, 2021, 10:47:06 AM
I've also been thinking about lowering the seat... any suggestions on that? Im going to keep the cover thats there, but maybe take it off and shave down the bottom of the foam... I dont know, just an idea
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Rhettly464 on March 04, 2021, 10:24:27 PM
Sweet machine looks great!! I kinda like that seat aswell looks sharp!! My belly pan is all shot on my invader 440 the plastic can break easy.  Canít wait for that racing to fire up again!! Nice clean motor aswell  :)
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on March 17, 2021, 11:06:26 AM
Quick update, put these on a while ago and they look better in person
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on May 26, 2021, 11:27:52 PM
Ahhh what have I done!!!!!! I know, I took apart my "prized" seat, but don't worry, the end result will look perfect.... I hope. I'm lowering the seat because the handle bars I put on work the best at a certain hight and at that hight the seat is too tall for me to be comfortable for leaning around corners. Also, I think it will sleak out the entire sled.
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Interceptor398 on May 29, 2021, 08:24:37 AM
Should be really nice when done.

Sorry for no updates lately fellas, I've been very busy with work and haven't been able to even get out to the shop at all. I did however go to the local vintage race sled show (put on by the race coordinators) and have a couple of very sweet sleds that I took pictures of that got me motivated again.
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Interceptor398 on August 08, 2021, 09:14:41 PM
Life is very busy here also.  At least you got out around some fancy sled!
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on August 24, 2021, 09:44:54 PM
Wow, I love it... it fits me nicely too. I'm sure an apolstry shop could have done better, but for my first time really doing a snowmobile seat cover (not to mention the foam shaping) im pretty darn proud of my self. I added the before and after photos, its about 3 inches shorter.
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Interceptor398 on August 25, 2021, 10:55:49 AM
Nice work!  Where did you get the seat cover?
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on August 25, 2021, 11:37:43 AM
The seat cover is the one that was on there when I got the sled. Just used it again

Post by: Ameritude on August 25, 2021, 05:33:01 PM
So I just remade the dash plate, the first one dident come out very nice so I made a new one. I also went and bought these bolts to replace the original flat head ugly ones. Gives it a nice finish
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on August 25, 2021, 05:34:05 PM
The dash plate is not finished im adding some switches and am going to be shining the whole thing up
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on August 26, 2021, 05:41:48 PM
I made a removable plate for where the headlight goes. It weighs about .8 pounds compared to the headlights 5 pounds. Thats the equivalent of taking 32 pounds off of a 3000 pound car. I know it's not much, but for the rules I'm abiding by, everything helps. And it looks cool I think. (P.s I kept the headlight of course so I can put it on whenever I want)
Title: Re: Boogity boogity boogity, let's go racing.

Your getting there!!!  Looking foreword to when the racing starts. ;D ;D

Post by: Ameritude on August 29, 2021, 07:24:41 PM
No clearance/travel issues and fully adjustable...also the clearance from the tunnel to the top of the track is the same.
Idk if it will work, but its worth a shot.
Title: Re: Boogity boogity boogity, let's go racing.
Post by: gixxer6 on August 30, 2021, 08:40:34 AM
I'm not really sure what I'm looking at...  Is that a 78 rear skid?  Modified? 
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on August 30, 2021, 11:56:46 AM
Yes, I took the limit strap for of an old polaris indy skid, that I had laying around, and modified it just a little to work on the 78 kawasaki skid. It pulls the front end up, the two pictures are before and after.
Title: Re: Boogity boogity boogity, let's go racing.
Post by: gixxer6 on August 30, 2021, 12:47:32 PM
Ahhh I see.  Nice! 

So the 78 skids didn't come with limiter straps?  I'm not familiar the the 78's...I use a 79 skid on the Intimidator and my 81 Invader has the Vari-ride...

No they don't unfortunately
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on August 30, 2021, 07:37:34 PM
Was just wondering if anybody knows if the factory tach for the invader is accurate at higher rpms? (7500-8000) Thanks in advance
Title: Re: Boogity boogity boogity, let's go racing.
Post by: gixxer6 on August 31, 2021, 09:36:59 AM
From my experience the factory tachs are quite accurate, but do not work well for anything other than stock.  They are small, hard to read, and can be a little "bouncy". 
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on September 01, 2021, 11:40:38 PM
Maybe excessive, and probably a bit overkill, but I'm still stoked. The brakes are off of a polaris indy 500, and the brackets that I made are strong enough to lift the whole sled. (I did, at least I lifted it enough to spill all the tools I had sitting on the sled off lol).
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on September 01, 2021, 11:44:48 PM
I can provide more pictures of the brackets if requested. I definitely would recommend going with a smaller caliper for just a simple trail rig brake conversion, but I talked to a guy who races down at eagle river and he said that for oval racing, the stock polaris brakes grip the hardest. I also got the whole assembly, master cylinder too, for quite a deal. The radiator and oil canister are just sat in place in that photo.
Title: Re: Boogity boogity boogity, let's go racing.
Post by: gixxer6 on September 02, 2021, 09:25:10 AM
Very nice! 

I've got an entire brake setup from a Indy 500 that I parted out for the clutches a couple years ago.  But it seems like it might be excessive for my trail rider? 
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on September 02, 2021, 01:15:36 PM
I would just look for a smaller caliper, it would make the mounting process easier. The master cylinder is perfect however.

Post by: Ameritude on September 28, 2021, 06:49:57 PM
The sled is almost done, ill be making an update in a couple days with pictures and video, but until then I have to figure out  my wiring problem. I rewired the harness because I wanted to route it so that it is hidden and now I have no power to the gages. I plugged in a spare harness aswell and nothing changes. I tried a new cdi box and still nothing, so as for the moment, im stumped... any suggestions. (I've retraced all my wiring and its identical to the other harness, the harness is correct as far as I can tell)

Here is a link to the wiring diagram.

Do you have power elsewhere?

The oil level viewer i made is like one of my favorite additions to the sled. This view looks pretty cool too.

Well some good news and some bad news... the good news is that I got the clutches cleaned and on the sled, the bad news is that my steering is way to sloppy, im not sure how I'm going to fix it but it seems like the engine needs to come out to replace that lower rubber bushing with whatever I'm going to. Has anybody replaced it with like a bearing? Anyways ill keep you guys updated.
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on October 03, 2021, 11:13:20 PM
Correction, it may be possible to only have to pull the engine "partially" out to access the bushing
Title: Re: Boogity boogity boogity, let's go racing.
Post by: gixxer6 on October 05, 2021, 06:08:57 PM
I have updated the lower sloppy rubber grommet to the newer style aluminum block with plastic bushings. 
Title: Re: Boogity boogity boogity, let's go racing.
Post by: Ameritude on October 05, 2021, 09:34:32 PM
Where did you get it from? Whal's? Was it a direct replacement, also thankyou for the response
Title: Re: Boogity boogity boogity, let's go racing.
Post by: gixxer6 on October 06, 2021, 01:30:10 PM
I pulled it from an 80-82 Kawasaki.  Or, I think it's the same as the upper block & bushings. 

I recall needing to use rivet nuts in order to switch to the newer style on the 79' Invader chassis.

I actually did this on the Intimidator.  You can see it in the picture on post #26 http://kawasakitrax.com/kawiforum/index.php?topic=1809.15 (http://kawasakitrax.com/kawiforum/index.php?topic=1809.15)

Post by: Ameritude on January 17, 2022, 11:28:48 AM
I've looked high and low for this info, and I can't seem to find a thread anywhere (let me know if I'm wrong). I have the sled all back together and it does start and run, not well, way to rich but thats a different problem. However, I have no lights, rpm signal or power to any thing on the dash. I have traced the wires that I changed and it matches a wiring diagram. I tested the two yellow wires coming out of the engine for ac voltage and its there. I am on my 3rd voltage regulator (2 used and 1 new) does anyone know what could be going on? Im about to go back out and figure out how far the voltage from the engine gets, but it seemed like it stopped at the regulator. Also, does anyone have some numbers to look for with resistance values or voltage numbers to expect. Thankyou in advance anything helps

Sounds like it may be a bad ground somewhere? 
Title: Re: Boogity boogity boogity, let's go racing.
Post by: mswyka on January 17, 2022, 02:53:18 PM
Ground is a good place to check since it is common to all.  It would be good to double check all the connections.  Sometimes when i have slid connectors together the pins have pushed out and not made contact.
Title: Re: Boogity boogity boogity, let's go racing.
Post by: mswyka on January 18, 2022, 06:46:03 PM
I went to ride one of our sleds last night and found that it had no lights or tach.  Tonight I found this - one of the connectors from the engine had wiggled out a bit too far.  I was able to push the connector pin back into place and proper operation was restored.
