Thank you. Currently, I do not have the bike running. Also, there is zero oil in the crankcase (in case it needs to come apart again). The transmission will not go into first gear.

So, today I removed the engine. It is sitting on a table waiting to have the lower half of the engine case removed. Hopefully, when it gets opened up, whatever was causing it to not shift in gear will become obvious.

 

Update: Got the cases split open today. All the gears look great. No problems with the actual transmission gears. Inspected the shift drum and shift forks. They look good as well. At this point it is difficult to see what is actually wrong and not letting the bike shift through the gears. My guess it is with the shift drum and forks. It is just hard to tell. The forks do not appear to be bent or excessively worn.

 

You should be able to put the shift drum through it's motions withe the case split. This should roughly be the same efforts as it is to shift, and might help you understand what's happening when you can't see things.

 

Thank you. Upon splitting the cases this past weekend we tried moving the shift drum. I have ordered a replacement shift drum and shift forks (ebay & inexpensive) to see if the new parts will make a difference.

 

The new parts arrived and have made a positive difference. The transmission now shifts the way it should. Just got to button it back up, stick it in the frame and go for a ride.

 

Glad to hear. LOL sorry it ended up being such a PITA. That bike's trans must've gotten whalloped.

Could you tell any sort of defects as to why the new parts made a difference? Wear marks?

 

The half inch diameter shaft that two shift forks ride on was marred up by the broken gear not letting the shift fork(s) to slide.
