Intruder Pistons wanted
« on: January 22, 2014, 09:00:04 PM »
Does anyone have two OEM pistons for my -79 Intruder for a reasonable price?
There are pirate pistons that can be trusted, it may well be fine too  ;)
Have heard of PSI pistons should be fine...  ::)

Must be able to send to Sweden  :-*

SPIs are fine, I have run them in my rider for about 5 years now.  You can also order Wiseco - which are high quality but $$.  I will arrange shipping to Sweden if you like.  Send me a PM and I will get you a quote.

I've had SPI's in my 130HP Ski Doo for the last season and a half without a problem.

I think I have 1 NOS Invader/Intruder Piston (no rings) that I'd sell.  But I'm not sure about shipping to Sweden...

Thank you guys  :-*, but now I have ordered these:

http://www.ebay.com/itm/Piston-Kit-Standard-Bore-68-00mm-Kawasaki-Intriguer-Drifter-440-Intruder-Invader-/290917991218?pt=Snowmobile_Parts_Accessories&hash=item43bc104332&vxp=mtr

BUT now looking for my brother two pistons to their LTD -80
Are there any of you who has those? I do not find any on Ebay   :-\
We bought pistons last year to his LTD but it was the wrong model year  :(
So is there anyone who is interested in them let me know  ;)

The diference between the Invader and 4/6 piston is the ring gap location.  Invader pistons will run in the 4/6 but the ring gap is on the intake bridge.  When the ring gets worn it can catch an edge and create some real trouble. 81 & 82 LTD's use a larger piston pin.

so i compared 3007 invader/intruder pistons with 3012 intruder pistons from 81 and up....12's have 2 rectangle rings that are both lower on the piston,top locating pin is in center, bottom pin moved to about 2 o'clock,07 top pin 5 o clock, bottom pin dead center.looks like they were trying for more durablity and had to relocate the anti rotation pins when they moved the rings down on the piston
