I have a 80 440 Invader that I restored, One of the parts machines I have is a 79 440 that has 4/6 cyls. on it. Can anyone tell me if I would gain any power with these? If not, what would they be worth to sell? Thanks.
-
Yes, they will add power. The last set I sold went for $150 each. They had very nice original chrome, and were not ported.

Thanks Gixxer6! that's what I was hoping to hear. I guess I'll be building the other motor and probably start over with clutching & jetting......AGAIN!
-
the only downfall is lack of pistons,pretty hard to find imo
-
I'm just starting to look for pistons now. Took it apart last night and found out that both cyls. have sleeves installed with 1 mm oversized pistons and one piston is damaged. I'm thinking these might be impossible to find!!
-
I put quite a few miles on my 4/6 motor with sleeved and ported cylinders without issue. It has .040 over Wiseco pistons in it...
-
does wisco have 4/6 pistons or did you use regular invader pistons?

The only difference between the OEM Kawi Invader and 4/6 pistons is the ring locating pin placement (and some of the 4/6 pistons had Teflon coating).
From my understanding, some aftermarket Invader pistons have the locating pin where the extra transfer ports of the 4/6 are. As you can probably imagine, it is not good to have ring ends where the port openings are...
I don't know about other brands, but I know the Wiseco Invader pistons in my 4/6 do not conflict with the ports. And it runs GREAT!
