Yeah, whatever. I strongly suggested that you spend 5 or 6 bucks on a couple of seals. Do it right ONCE. But what the hell do I know?....have fun with your clapped out junk...no more advice from me....:fu::fu::fu::retard::retard::retard:

If it starts sucking air and running lean he can give it some choke to compensate.

Long skinnies, yeah top end.

Short fatties more better for torques but,
it'll still depend on the size of powerband installed and how many, as mentioned.

I use the blue powerband on my 2 strokes, the red powerband is just too aggressive.

Surprising that it ran like a bat out of hell with this damage!

Looks like I'm going 2nd over on the top end!

Man, that's deep! Point Five-O oversize is going to be close to cleaning that up! I have a Kwik Way FWII sitting at the ready.
I shudder to think of the cost of a piston kit for that thing!:eek:

I worked on an old shit heap KZ1100 with a huge bore kit on it aboot a year ago, it had Teflon Buttons in the pins. Hadn't seen that in decades. But then again the beater was a 1982 shaft drive unit.

I remember when SeizeCo Pistons were sent with Spiral Lock wrist pin clips. Those fuckers will not fall out...ever!

I used teflon buttons in all my big block Kawi's. Worked great!

How long ago?

I wonder how'd they'd work in a two cycle? It could possibly cut down on turbulence from the wrist pin hole going past the transfer ports. I guess I should have tried it back in the day.

Boring cylinders on a mill or lathe sucks ass when compared to using a proper boring bar. I've done one on the mill and the lathe, fuck that, massive time suck.

Billetman has bowed out and I haven't the slightest clue about boring cylinders so I guess I'll ask around locally.

You need to find a crusty mofo who's annoyed by your presence and insulted by you asking him to hog out your holes. He the guy you want.
I've seen cylinders that look like they were bored by a rat tail file! I've also seen some with boring marks left in them, along with razor sharp ports, no chamfer at all. I hope those pistons you ordered come with some suggestion for the clearance, if not you have to go with the factory specs and hope those pistons will work with those numbers.
I'd be real interested in what they charge per hole.

I have to bore a Banshee upper case to fit larger cylinders. Will not be that enjoyable.
