Squeal/squeak coming from engine
 

Hi all, had a search around and couldn't find anything, sorry to post ANOTHER thread!

Having a little trouble with my xt's motor, basically it squeals/squeaks when 'pulling' in low speed, i.e setting off in first & low speed acceleration in 2nd (15-25mph-ish).

The best way I can describe it is akin to the sound of a squeaky fan belt on a car (a sound most people will be familiar with). I'm not very mechanically minded so wouldn't know the first place to start looking. Do these bikes have a belt of sort that could cause this noise? Any help would be much appreciated.

Thanks.

EDIT:
Got a video:

Dose it make the nose in neutral with the clutch pulled with the engine running.?

Nope, nothing.
The engine does make a 'chirp' noise if i rev it, the squeal seems to be an extended version of this.

Got a little video if it helps at all, will try to get one of the bike pulling away although it would be tricky to film haha.

The chirping sound can be heard 17 seconds onward in the video.

Sounds like the early noise of a loose primary drive nut on and off the power and withwhen the slack is taken up in the transmission check this play list of noise and fix ... this noise is in the later more clunky stagesXt660 primary drive nut: http://www.youtube.com/playlist?list...s3MyCuVkSQuKKP

I managed to get a little video of the bike setting off, you can hear the chrip/squeaking noise quite clearly.

Does that sound familiar to when you had the loose crank nut?

Thanks a lot.

Yup sounds like it to me

Looks like a trip to a mechanic for me then, don't have the tools, skills or a garage to work in..damn :(

Basic allen sockets . Normal sockets oil water and a couple of hours .... oh and a torque wrench .... anywhere near hull?

A good set of tools is on my to buy list, I've got a basic socket set and a torque wrench though.
I'm actually in Hull my self yeah.

If u get stuck I can guide u
