i am planning on ordering wiseco 10:1 or 11:1 piston kit from motoman. what would be a better choice and things i should know about it

 

If you get a wiseco be sure and let it warm up good especially when its cold cuz it will seize up.

 

With the 10:1 you can run regular pump gas and you'll notice lots of extra power. With the 11:1 you might have to run an octane booster or race fuel. Although an octane booster should be alright. I'd get the 10:1 if I were you because you can get gas anywhere then and not have to worry about using an octane booster.

 

do you have to bore with these pistons? -or can I just drop one in? Anyone know who has the best mail order prices?

 

No you can get a standard size and drop one in. Just check some prices in dirtwheels and order from the cheapest one is what I would do.

 

Remember to hone out the cylinder using a cylinder hone, and check your cylinder for deep scores cuz if so you'll have to bore it to the next size, a cylinder hone only takes out microfine inperfections.

Hone then maesure the bore, then order a piston to fit the bore, don't forget to check your ring gap before installing. While apart this would be a good time to make her breeth a little better.

 

k&k atv has the 10:1 for 99.00 www.kandkatv.com they have really good service i just ordered stuff and there were great

 

I got my wiseco for the zuki from my dealer. He ordered it out of Parts America I think or Tucker for like $55.00

 

I have had bad luck with WISECO pistons. I would'nt wish taking the motor apart and flushing piston bits out on anyone.
Also, with the 11/1 piston you can run octane booster to fulfill octane requirements. This can lead to other problems....the octane booster leans the fuel mixture a tad and gives the Wiseco a reason (like it needed one!) to seize. Wanna know why they are cheap? Because they are moto to moto throw aways.
