I picked up a 1987 Honda Fourtrax 350 and I am running into some shifting issues. I knew it was a problem when I purchased it, I was hoping it would be an easy-ish fix but it's proving to be harder than I anticipated. I am not super mechanically inclined, I can do the basics, I work in the IT world and it helps to keep a project like this in the real world.
Here is a video of the behavior: https://youtu.be/xF6WF_SaDVc
Machine details:
Year: 1987
Model: TRX350
Engine Serial: TE07E-8100346
Frame Serial: JHSTE0706HK100272
Location: Livonia, Michigan
Engine status:
The engine runs perfectly, obviously could use a carb cleaning since it's been sitting for a while. But it starts up using the electric start and runs fine.
Problem:
When I got it, it would be in neutral, I can shift into low gear and it would move. It would however not allow me to shift beyond the low gear. I was able to get it into reverse but only twice, after that, it just would not go into reverse. After fiddling with the shifter I was able to get it to go to second gear but then it would not return to neutral. I rocked the machine and was able to get it to neutral, tried to shift again this time it's stuck in gear.
What I have done:
I took apart the right and left covers. I don't see any RTV silicone just a black OEM gasket so it appears that either I was the first to take it apart or that whoever serviced it in the past did it right.
What I discovered:
The decompression follower was broken and sitting in the bottom of the case.
The gearshift return spring was bent which explains the excessive play and clicking in the shifter.
Current state:
At this point, I am lost as the machine still appears to be in gear. When I spin the wheels, the clutches are spinning and the machine appears to be in gear. While fiddling with the shift lever I was able to get it into neutral, and when i spun the tires, the clutches would not spin. Then shifting, into low, it spins the clutches and will not go back into neutral. I believe that there may be an issue with the gearshift drum or one of the components under the gearshift arm like the pawls. I am not sure. Any help would be appreciated. I also would appreciate if there were a way to find a tech in the area who can work on this. the dealers wont work on anything that old they say.
