Thanks. Just realized no new wrist bearing. Oh well, still have to take to get measured honed

So I got my wiseco piston.... however regardless of why I ended up with a 66.00 mm piston. The current Chinese piston said 65 .74 or 76 maybe. My question is- despite my crazy bad current clearances is that roughly.25 mm gonna be enough to hone my cylinder to tighten up the specs? I don’t...

I would sell. However would prefer hands on transaction. I live an hour west of Albany. How’s 200 for all sound?

I measured the piston to cylinder wall clearance on this most recent tear down and was appalled by by how much clearance I have compared to what is acceptable. Didn’t even write down as they were so bad, I’m talking .015. Mind you it’s probably had 20 tanks of gas ran through it the last...

Forgot to add- yamalube @ 32 to 1. (4 oz per gallon) also when I did the crank I used yamabond. When I did the top end just know I used permeates aviation cement for base and intake gaskets. Also I read on here that very few applications call for a larger pilot jet, so what happens when oil...

Last riding picture before departure

Threw the tools in thier just so nobody thought I pried my cases apart with screwdrivers lol. Had a cr250 I rebuilt that I had to use jb weld on for that reason like 25 years ago l

Sorry about posting where and what- not to tech savy. Watched KOR’s videos and others and not sure if exhaust port should be raised when running either a knock off piston or the vitos super stock wich both have the lowered piston exhaust side. Wondering if the combination opens exhaust to soon...

]Hello all. Long story short , have had many many bikes and quads over the years. Couple years ago , couple years before my sons departure to Paris island we picked up a pile of blaster parts and tried to put one together out of what was there. Riding , locked up, tore down, wiseco crank ...
