help deciding engine rebuild

[WickedATVer]

Any heard of namura sleeves or does it realll matter?

I have a gasket leak on my 400ex. Right now I have a 88mm piston with stock compression wiseco piston. Now what i wondering is should i just get a new gasket kit (a metal one) and put it all back together. Or for a little more money get 440 kit off ebay for $170. does anyone know about Namura sleeves.

thanks.

You probly got a gasket problem because the studs are pulling out.

Either way you decide to go i would get HD head studs installed.

The 440 will need them.

The 440 is a good kit, its puts out great power. You need to build it right though. HD cam chain, HD studs etc...

Call Colby at CD and ask his opinion. He will not steer you in the wrong direction.

I also recommend you get your parts there. Ebay isn't much for help after the sale, Colby on the other hand knows his stuff and will bend over backwards to help you with the parts you buy from him.
