Doing rebuild, what else?

[01Flamer]

A couple buddies of mine and I tore into the Banshee on tuesday night, the jugs are now being sent out to get bored the next size up (was stock bored), the pistons are on order and so is the thin base gasket. I was going to send the jugs out to get ported and polished but, I desided to bore and put a high comp. piston in my Raptor since it was using alot of oil. But anyway, are some little things that I should do to the Banshee to add a little more power???

Change the oil seals. During every top end rebuild your saupposrt to change the seals to prevent the oil going up into the top end. It wont add power it will just save you time from having to take the engine out the second time and doing it later.

Maybe some v-force reeds? I looked in ur signature and it didnt list them. They always help out.

I'd get the shift star modified while it was down. I'm amazed at how easy it is to shift and find neutral...puts the yfz to shame!

you do know a machinist should bore the cylinders to the actual piston size correct? I piston will come 64.40 or something like that as a list, but it may actually be 64.49 or 64. 396 or anywhere around there. When a cylinder is bored, it can be bored to the thousandths, and creates a much tighter seal.

Your right, the machine shop isn't going to bored the cylinders until they have the pistons. I was just saying that I was going to have the cylinders bored instead of just doing the rings, even though the cylinders were at 64.39 and 64.393.

 

I was thinking about advancing the timing +4 deg. and maybe putting in new reeds and also spacers. Anything else??

 

Thanks guys!
