Shifting after rebuild!

[quepasa69]

I think I know the answer to my question. I split the cases, all new bearings, gaskets, bore job, etc... Wasn't sure about it shifting right after cases put back together....so I finished putting it together anyway. Set engine in frame, connected clutch and it just felt like I had neutral first and second..then just neutral. Haven't started or filled with oil yet. Pulled clutch cover, and clutch back off. In the pic is where the shift star is at now, and its basically stuck in neutral. Cant turn it to get it to go into any gear now. Looks like Im going to have to split cases again to see what happened. Any suggestions??

One of the forks is in the wrong place or one of the shift fork shafts wasn't put back in place when the cases were put together.

You should always check the gears while the case sealant is still wet. While turning the input shaft (the one the clutch bolts to) and turning the shift star, the output shaft should clunk and change speed. 6 gears plus neutral. If it doesn't, it's easier to pull the bottom end back apart right then.

When the shift forks are put in place, does it matter what position the shift star is in? And which way do you turn the shift star? clockwise or counter clockwise. Or does it matter? Think I will be ok to reuse my yamaha base gasket? I did put yamabond on it.

As long as the forks and fork shafts are properly installed, it doesn't matter where the drum is at in it's revolution.

I went through this yesterday.... actually. Looking at the star of the shiftdrum; clockwise is downshift, counter clockwise is upshift.

Remember, neutral is between 1st and 2nd and you have to be turning the input shaft in order to shift. Engagement dogs don't like going in unless the assembly is moving.
