Posted this in a Honda-specific forum with no response. Hopefully I can get some helpful info here....

I had to split the case on my non-reverse era 400EX to install a new crank. All went well, with the exception of the transmission, specifically the shift drum.

I tried following the Honda service manual, but the few pics they included did were grainy black & white, and they did not give much explanation to getting the shifter aligned with the drum correctly.

I got everything back together and took it on a test ride. 1st and 2nd shift fine, and most of the time 3rd was ok too. When I would go into 4th, sometimes it would go into neutral instead of 4th. I could downshift and try to upshift again, and occasionally I would get into 4th. Sometimes I would get a dead shift, where the shifter wouldnt want to click up at all.. I could downshift and then try to go up again to get it to work.

Before I break this thing down again, does anyone have better pics, or some advice as to getting the tranny back together correctly? How can I test it, so that I know things are aligned as they should be, BEFORE putting the top end and remaining lower end together?

 

You must have put something in wrong possibly

 

ive never fooled around with my trans that is a no zone for me
