Testing the mono shock bike at Darlington Dragway.
« on: March 25, 2023, 11:28:34 PM »
Decided to go do a little testing on the mono shock bike. I haven't been on it for a while. Last time out it seemed like the bike wasn't reacting when I released the clutch lever. I pulled the cover and took all the plates out thinking I'd find a broken fiber or two. Much to my surprise,  all I found was very slight discoloration on one steel.  I moved a few plates around,  oil up the fibers and put the plates back in. The one thing I discovered when I was adjusting the cable at the cover was the adjuster wasn't seated inside the housing. Hmm. I never noticed this before. I determined that I just need to switch out the end piece and it slipped right in. My guess is the cable was randomly hanging up before but I needed to get to a track to verify my hopeful solution to the lack of proper reaction. I also had issues with the bike not shifting correctly so i made changes to the shift killl time by increasing it to 65 milliseconds.  On my first  hit the bike left good but momentarily missed shift. I bumped the button again and all went well until i chopped throttle before the stripe. I came back and bumped up the kill time a few clicks. The 2nd pass the bike shifted great but i bogged slightly off the line. I also bumped the shift button a little before the stripe knocking off ET and mph.  Overall i was satisfied with the test passes and successful changes to the bike. I just need more seat time to lower my 60 foot more and get comfortable with the bike again.  I'm about a  tenth off my best ET on the bike right now. My next time out I'll probably put a nitrous bottle in and set a soft tune up. I'm curious to see how an sohc will react to laughing gas.

The man clearly likes to go fast…and knows how to do it!

Nice job Frank. Are you going to disassemble the clutch again to see if anything odd is going on still, or are you satisfied that the prior issue is resolved?
David- back in the desert SW!

I'll make a few more passes to be certain I can get repeatability in the reaction and 60 foot times. I feel confident I solved the problem by replacing the adjuster. I didn't realize there were 2 different sizes until now. I'd really like to try Kenny's 6 spring GL clutch one day but want to push the stock setup to its limits first.
