Default Keep stripping Pinon shaft

Hello guys, hopefully someone can give me some insight.

I just got done building my evo up, and put a new starter in it. After getting it back the first time, I had stripped the pinion shaft, but didnt think anything of it. Then I had the shaft replaced and clutch gear, now its stripped again.

My compression on the engine is only 10.5 to 1, and I have a 1.4kw starter, nothing radical. Can anyone tell me what I need to do to get the starting system reliable???

Thanks
Matt Wenning

10.5 is nothing to sneeze at. Compression release maybe??

How does it spin over? You're timing may be to far advanced and that will tear up starters.

push starting is easier in 2nd or 3rd gear

Got it to the shhp, we are going tohave to go w compression relasers. So anyone thinking of going up in compression, just get them anyway to save yourself a ton of time, and a ton of money in broken starter parts.

Hopefully this will save someone else.

Other than that it runs like a completly different bike, Im very happy with it.

As I said................ been there, done that, and mine's only at 9.8:1Your advice to "Do it now anyway" is a good one.
