Stroker Crank


Recommended Posts

i dont think you can go wrong with a wiseco. as for the bore job, is it needed? you might want to do it anyways because your crank will most likely be a 5mm longrod setup as well. this requires the use of wiseco 795 series pistons. and we all know you should bore for some new pistons.

No it does not need to be Bored. But we were talking about getting it bored 40 over when we have the Stroker crank put in.

Vito's 4mm Stroker crank is NOT made by Wiseco, and Wiseco cranks are NOT made by Vito.

 

I would go with the Wiseco H129 stroker crank. Why? Because it's better. It comes from the factory Trued and Welded. It has the +5mm long rods which lessen the rod angle and extend engine life. It's macked by a multi-million dollar, multi national company with a great reputation. Rebuild parts are available through virtually every Cycle dealer in the USA.

 

Depending on your porting specs, you would require either a spacer under the cylinders, or on top. If you'd like to know which to use, PM me or e-mail me at gunner@jpl-atv.com and I'll help you figure it out. Oh, and, No, the Wiseco doesn't come with the spacer plate, because Wiseeco gives you a CHOICE. :D

 

:cheers: Cheers!

my cat. shows them to available in sizes: 64mm, 64.25, 64.5, 65, 65.5 all with a 54mm stroke. about the gaskets i wouldnt get it if you can opt out of it. since the cool head uses it own seals (the o-rings) the only one you will need is the base gasket, two base gaskets if you use a plate. maybe some reed gaskets as well, but i dont think those are included in the topend gasket kit.

To run stock pistons, not the 795 series, take your domes in to a machine shop and get 2 mm cut out. This will give you the same compression without using a stroker plate. But as for the port, I agree with rebel banshee. You will not realize the full gains that are capable without a "port to the crank" i made the same mistake, and have to tear my motor down again this winter and have the cylinders re-done. I was getting blown away by modded raptors..camkit, pipe, high comp piston. I should have been blowing him away, but with the port job i got, i am only running about 60% power.
