    I bought a 2004 Scarver as a commuter bike - brilliant!!! Handles like a 250 but easily pulls to 90 mph, sorry, 70 mph! BUT, I just had a catastrophic failure of the rear belt sprocket. Close examination shows it was worn out. So, I need a rear sprocket and a front sprocket. The belt...

    At roadside waiting for circlip to re-attach recently replaced front sprocket. Has this ever happened to anyone? Can't think why the old circlip came off.

    Recently fitted a 15T front sprocket to my 2000 Funduro as opposed to the STD 16T,much better in my opinion, A much nicer ride,esp with pillion/luggage,more low down and mid range grunt,a lot less cog swapping at low speeds, pulling top gear in some places where i was using 3rd and 4th...

    Can anyone tell me which way round the drive sprocket (Engine end) should go, With the raised lip facing the engine or with it facing out. It seems daft but I cant remember which way round it should go. I blame the wife for yelling at me to come in for lunch. Many thanks. :confused: :think:

    Hi Well I am down to the main shaft drive sprocket... The Clymer Manual says to put a 'soft washer' between the main sprocket and the sprocket of the clutch basket.... then take the nut off... Agghhhh.. is this the only way? Really worried about damaging the main sprocket or clutch...

    I am changing the chain and sprockets on my 1999 Strada. This has the later type of gearbox mainshaft with a nut. The manual says there should be an o ring behind the sprocket (I have a new o ring). Is this only applicable to the earlier models where the sprocket was held on by a circlip - I...

    I am replacing the chain and sprockets on my '99 Strada which has done 22,000 miles so it might be the original parts. I was ready to put mega torque on my breaker bar to remove the gearbox sprocket but the nut was not tight, although the tab washer was in place. The old sprocket has...

    Hi Just had my 650ST MOT'd and it passed but I was warned that the Chain and sprockets were worn. In the past i have been told that a front sprocket one tooth smaller helps to reduce the low speed snatching. Has anybody tried this and does it have any other effects at all. Thanks a lot Rob

    Last night on the way home from work I heard a disgraceful rattling noise from the back wheel. After pushing it home the last quarter mile I took the wheel out and lifted the sprocket out of the hub. Ball bearings all over the shed floor and wisps of metal that used to be the inner and outer...

    What is the smallest rear sprocket you can get for the funduro which may also be the same for other BMW 650's? It's actually for my Aprilia Pegaso 650 but shares the same rear sprocket as the Funduro I believe. Smallest i've seen is a 45 and i'd like a 40 ideally... possible? I think...

    hi all, the other day i noticed my sprocket carrier could move slightly, so i have just replaced the rubbers but there is still just the same amount of movement as before. so my question is; is the sprocket carrier meant to move a little or is it meant to be firmly healed in position? i have...
