I'll try to describe this as best as I can. Another case of the "I loaned my bike to a friend and now it has so-and-so problems." The trail he was on is fairly small, not exceeding 20 mph or so. By the way, he sucks at driving manual if that matters.

Anywho, he returned it, and simply said "it was cutting in and out" then just left. I wasnt sure what he was talking about, so I took it for a ride. It took 3 or 4 tries just to get it in gear. I took off, and the clutch slipped. I got to about 5mph, and I could not get it to shift into 2nd gear. I tried 10 times or more and just couldnt shift up.

Within the last month I replaced the shift forks and oil (rotella 10-40 with jaso-ma rating). Within the last year or two I have replaced the clutch plates and springs as well as the clutch cable. The oil level was slightly high when I checked it yesterday.

Any ideas? I'm pretty p*ssed off at the guy who was driving it, but I'd rather figure out what the problem is before I start pointing fingers.

the only way to find out the extent of the damage is tear down and inspect. if he cant drive a manual very well he probably figured out he could shift without disengaging the clutch and was slamming gears.

He doesn't sound like a good friend to me if he cant respect your belongings and i don't know if i have any friends good enough to drive my cts lol

Going by what you posted,look for a bent shift fork/chipped 2nd gear when you take it apart.Sounds like ''your friend'' should pay you for the damage he did.

Stomping the shifter and not even burping the throttle was my first thought. Your a whole lot nicer than I would have been to that "friend". IMO, he knew he did something to it. Hopefully just the shiftstar came loose.

blah blah bad friends join the club....
One time i let a 'friend' of mine borrow my 2 door cherokee to drive some morons back to where they came from (mistake). it came back with the door HANGING off, due to someone leaning on the door to get out, and then pulling the welds of the hinge off the body almost completely. i noticed immediately, and when i called my friend out on his damage to my cherokee he said something like 'it was already like that'. No it wasn't, i'm not stupid. Now i avoid these situations the best way i know how... Have no friends!! :24:
Just kidding, but, since i do own so much stuff, i no longer lend anyone anything without being a complete richard about it or making them 'rent' it from me. seems when people have to pay they have more respect.... BUT, i digress,

I have a 71 ct70h, and it's a true survivor. i can't tell you how many backyard beer induced wheelie attempts it's survived, or how many people have tried the 'i've never driven a motorcycle before' crash course (literally) clutch and transmission tutorial. AND, despite all this abuse, and a 108 cc BEAST motor, it shifts flawlessly, and the clutch engagement is smooth too. I put plates in one time, and some springs. the trans has been out and cleaned, but is all original, shift forks, washers, bearings and all. Since you went in and did 'work' to this motor, i would start by checking it. how does the clutch lever feel? does it disengage? when/if you get the cover off, remove the clutch. see if you can shift through the gears while rotating the trans input shaft by hand. if you can, it's most likely a clutch problem. if not, tranny all day.

Like i mentioned (about the clutch) when done right, they're almost bullet proof (ime) stock. and yes, in lapses of judgement i've loaned my bike to people who have used it with fairly little idea of how to operate a clutch, and it still works fine.... let us know.

Will do. Its 97 degrees here in Milwaukee WI so I'll either wait until tonight or I'll do it in the house.

The clutch lever feels like it always has. The star washer seems likely at this point.
