Wheel spinning / Chain loose / Bike fewked?

[_Stretchie_]

So there I was hooning around this nice right hander when all of a sudden the bike revved up a bit and it seemed to drop, then the power came back and I made it round.. Phew!!!

I just thought maybe I'd hit some gravel around this corner and it just made the wheel skip out. Anyway, after a few more times with it happening, luckily just overtaking so I was upright, I was feeling uncomfortable and then again around another corner so I decided to pull in at a pub have a coffee, stop shaking and ring a mate for comfort.. TopDec... No answer.. DAMNIT

I've not had time to try and replicate it but I'll try in a 'safe' environment.

How it feels:
You know when you pull away from a set of lights in the wet and you give it a little too much throttle, the revs jump up for a second and it shakes the bike before getting a grip on the road again. Well that's how it feels, only the back end does not slide left to right.

SO I don't think it is actually the wheel spinning, from the sound I thought maybe the chain was slipping. I changed the chain and sprokets (front and back) a couple weeks ago and have not tightened it since, I thought it may be down to this and adjusted the chain accordingly when I got home last night. But again it was happening on the way to work this morning. It seems to happen when I give it some throttle, so at the moment I have been short shifting and riding like I would in heavy rain and it hasn't done it while doing this.

Any idea's??


Cheers

Clutch is slipping!

Yup.. ill put cash on clutch.

Best thing to do to check is engage 4th gear and ride along at a steady 40/50mph.. then without changing gear, accelerate HARD. If the revs increase but speed doesnt.. its ya clutch.

Its FUBAR'd.

Not reallly, it could just need adjusting

If it does, adjust it at the engine end first (According to the manual(if you have one)) then at the lever

In my experience, if its got the stage of slipping at 40/50 in 4th gear, there aint no point in just adjusting it, its already majorly worn.. Get it replaced.

It's well worth checking and adjusting it first before forking out on a new clutch, no point in spending money on a new one if it's not needed.

Reckon it might be worth letting your local mechnic have a look if the chain/cluch advice doen't work

How many miles has the bike done?

Yup, clutch to me...

Girlfriends car done this, floored it, lots of revs, lots of noise, but didn't go anywhere

Gah, and with all the money top teams are throwing at traction controll now-a-days you guys are telling him to adjust it out or replace a race trick part?


I'll get me coat

I'd also check the front sprocket is still on right.

The clue's in the question:
