Folks,
Just replaced the clutch on my k75rt.
Things were going very well. Until very recently (I'm in the middle of a trip from Madison, WI, to New Orleans and back up to Boston - I'm currently in New Orleans) it feels like the clutch is slipping again. It's the same feeling that caused me to replace the clutch in the first place. Heavy acceleration at low RPM in anything besides first gear causes the bike to slip into higher RPMs with no acceleration yielded. This clutch is brand new and when I replaced it there was no sign of it being fouled so I didn't replace the O-ring toward the engine.
The bike is rideable, its just frustrating and I'm fearing it will get worse.
Any ideas? :dunno2:
Thanks in advance.

Correctly adjusted? Sticking pushrod or piston?
-
It was correctly adjusted when I started. Haven't checked it since. What might be the remedy for a sticky pushrod or piston?
-
The pushrod could be bent, the piston could be damaged in some way.
Unhook the clutch cable, remove the boot and check that both the piston and the pushrod moves freely.

I am a — how do the french — Le Noob...
the pushrod i got.
which part is the piston?
thanks,
again.
-
The piston is between the lever arm at the gearbox and the pushrod.
It`s rather unlikely that it should make any problem, but it won`t hurt to check that it moves freely.
You must remove it anyway, to get to the pushrod.....which can`t be removed to the rear on a 75.
-
If it's slightly bent and sticking then letting the clutch out quickly might help it slide all of the way back and engage the clutch freely. May be a bit tricky since you'll need the RPMs just right.
When you adjusted the clutch did you undo the lock nut on the bolt in the clutch arm, back the bolt out and then turn it in only until some resistance was felt?
-
duck,
ya that's exactly how i did it. it's a pretty snug — almost no play in the clutch — so maybe i'll back it off a hair just for good measure and see if that makes any difference.
thanks for all the input i'll do some tinkering here in the next day or so.

The play should be adjusted at the handlebar lever.

Don't wish to alarm you but did you check the drive and pressure plate for dishing when you replaced the disc.
My K1100 was dished so bad that only about 3/16in was griping at the outer perimiter of the disc and would slip when ever I applied even a very moderate amount of power.
-
Did you replace the pressure plates too or just the clutch plate? If you ride around around long enough with a slipping clutch you'll "glaze" the pressure plates.

good brick people,
i had no play in the clutch cable.
:hehehe
doh!
