Clutch adjustment....slipping

I have just noticed what feels like some clutch slippage while under heavy accelleration in 4th 5th gears.

I am not familiar with the Harley clutches but previous experiences showed internal clutch adjustment only helped if the clutch wasnt disengaging enough (ie. too much freeplay in cable). Adjusting never seemed to help clutch slippage.

The clutch has not been adjusted recently and the cable has sufficient freeplay.

For a sportster can clutch adjustment reduce slippage?

If the cable has enough free play you will not be able to adjust slippage with the cable, you need to check the adjustment at the adjuster at the clutch itself.
If you send me your e-mail address i can send you a PDF of a slightly earlier sportster clutch with the same set up, with the details of how to adjust it.

My experience is like yours...if your clutch is slipping under a load, your plates are done.
I've seen guys band-aid a MINOR slipping problem, but it gave 'em just a little more time, and they still had to baby it.
How many miles on it?

Kevin is correct, once they start to slip they're close to done. I'm curious about mileage and the oil you are using. When I had my Dyna the transmission noise was hated by me. I used Motul 5100 on a couple of Motocross minis I built. Best tranny oil I've ever used for noise and ease of shifting. My XR also came with tranny noise as standard equipment so I put some 5100 in the tranny and it reduced the noise big time. Since the XR used the same oil for the primary as the tranny the XR didn't like the 5100. Clutch felt weak and about to slip so I went back to the Formula + oil in the tranny. The clutch came back to feeling strong and the tranny noise returned. Oh Well, Damnit! :censored: Later,

I had it on a dyno the morning after I sensed the slip and it performed fine.....no slip noticed at all. On the short trip home I didnt notice any slip so perhaps I was just suffering from pre-dyno nerves and guilt about a few too many drag starts. Sorry for the false start.

transmission oil/clutch slippage

Billy-I have been using Amsoil 20w50 synthetic in the oil tank and primary. It is also rated fro use as 90W transmission oil and at 5,000 miles on the bike now, I have not noticed any clutch slippage or tranny noise. You may want to give it a try in your tranny some time-Thanks again for the info on the Showa BPF fork-Mort

Hello Kev, I'm outta the mini buisness but I built two. Honda Crf 50. Red Baron frame, Marzocchi, forks, 124 Kitaco engine, close ratio tranny, 12 inch front wheel, inner rotor ignition. Around 17 horse power. I also buitl a KLX 110. Elka rear suspension, Marzocchi forks, 143cc engine kit w 4 valve head, Flat slide carb, shift drum for 4speed tranny with close ration gear cluster, modified kickstart gear. It made around 20 horse power. These were the most maxed out minis in this area of the country. David Pingree rode the Honda at a pit bike race after the Atlanta Supercross a few years ago. He said it was as good as his Red Baron built racers. After building these bikes there wasn't many places to ride and no real races so I got out of the mini scene. But I had a couple of real hot rods. It was fun! :clap: Later,

Go to www.hondaminitrail.com if you want the best and most mini racing parts. I'll make you get out your check book. I bet there is a old junk KLX 110 back in the shop that needs love.
