It's been a while since i made an update. I did get the gearbox installed and have been able to take it for a couple quick rides around the house. From the little bit that I have rode, I'm fairly impressed with how well the clutch is working out of the box and the gear ratio of 9:1 seems to be perfect. I've still got a couple issues to work through. I plan to take it back apart soon to rewire everything and replace the
Engine with a bit lower mile one that I've recently acquired.
I've been looking for an input shaft support bearing but havent been able to find anything that was narrow enough to fit my current setup. Currently, there is a 3/4" spacer between the clutch and gearbox, and the clutch hangs about 3/8" past the end of the shaft. This was the best place to make the
motor ((
Internal Combustion Engine ? )) fit and the clutch clear my muffler. Most of the bearing blocks I can find are over 1" thick and there is not enough shaft space for that unless I make the clutch hang even further off of the end of the shaft. Im not sure what other style of bearing to look for. I need to find somthing 3/4" thick or less. Any input here would be greatly appreciated.
My second issue is with the shifter. I used 100% of the stock pilot shifter. The rpm gearbox uses a square post for the shift lever, so I filed the splines of the original pilot gearbox shift lever into a square. I thought this would be adequate as I can feel the detent when I shift into gear but after a couple minutes of any big or small load it will pop out of gear. Initially I thought maybe there was too much tension on the cables, but even with 1/4"+ of free play it will jump out. The only other thing I can think of is maybe my shifter needs to latch when its in gear?
I don't have many good pictures, but I'll post what i have. Should have taken more while i was in the build process because it's not easy to get detailed pictures of stuff when it's all together.
