my question is not towards the piston side but towards the gaskets do they come with all the gaskets and o rings to take the top end completely apart and clean the kips and all the covers and such? and put it back together with new gaskets? also I have never done the top end ( first time) do you have to have any special tools like to pull the piston pin out? also in the service manual it says use 2 stroke engine oil to coat the cylinder and piston and pretty much everything else to but is that premix they are talking about or is it a crankcase oil of some sort that you can't change? or am I completely off? just trying to clarify. appreciate the help.

Well, the first thing you need is a service manual. Then you need the piston kit and a top end gasket kit. The piston kit alone does not come with the necessary gaskets. I do think wiseco offers a top end kit that does have the gaskets you need though.

No special tools are really necessary. You can remove the circlips and start the wrist pin out with a matching socket. For lubricating the cylinder they are talking about 2 stroke premix oil. There is no oil held in the crankcase of a 2 stroke. There is plenty of debate about dry fitting or oiling the parts though. Take your pick I guess.

I don't think the Wiseco piston kit comes with the rod small end bearing, either. When ordering the piston you'll need to order that as well.

The gasket kit will have some extra gaskets. Don't let that throw you!

There is lots of info on here about the pitfalls and tricks to a top end job.

I meant to say the top end kit. from wisecos site it comes with piston, rings, circlips, wrist pin, top end bearing, and gasket kit for $231. I don't run race gas just race premix my bike likes it and runs awesome on it, tried the redline and my bike seemed to run like crap, like it threw it out of tune. I do have the service manual, it does do a pretty good how to on the top end tear down and rebuild, so Im not lost but if I have any questions I am pretty sure someone on here knows the answer.

Yep. If you've got your service manual then you want to order up the parts and tear her down. If you get stuck anywhere for any reason, I'm sure someone can help you figure it out.

You should make sure you have a 6mm open end wrench to hold the KIPS shaft while you remove the reverse thread nut on the end of it.

also guys on break in is there like a how-to on that. I know you are not supposed to start it up and just go romp on it. as far as I understand it start it up let it idle for 5-10 minutes turn it off let it cool down. next start it up let it idle for 5 minutes go ride it with only up to a 1/4 throttle for 5-10 minutes let cool down, do 2 or 3 times. next start up ride moderately up to 1/2 throttle for 5-10 minutes do a couple times. next start up you are now officially allowed to gas it. does this sound right or am I missing a step or two?

Really? I start it and ROMP it!

Jeeeeez... not the break in debate again...

No other comment

Yeah. I try to break them in. I usually make it through one warm up / cool down cycle, then try to ride at low throttle for 15 minutes or so. Good luck with that. It's just much too tempting to hammer back on the throttle after all your hard work!
