Dynamo_Delboy Posted June 26, 2014 Share Posted June 26, 2014 Right got a problem here.Recently when ive been riding the old CBR600f2 ive noticed that when im accelerating through 2nd gear the back wheel seems to jerk like its lost traction or chain slipping on sprockets. It only happens around 6-7k rpm and only once or twice before its runs normal.The tightness of the chain seems fine but a while ago i had a siezed link that i managed to free with a good clean and lube.Also recently adjusted the clutch cable (only slightly) so wondering if anyone has any ideas what it could be?P.s. When im approaching the 6-7k rpm mark the power seems to bog down slightly then after the jerk its fine.Helllllllpppppp meeedd pleeeaaasssseeeee!!!!!

Mr Fro Posted June 26, 2014 Share Posted June 26, 2014 Chains don't tend to just slip on the sprocket unless there are no teeth left or the chain is ridiculously slack.If it's bogging then it might be a fuelling issue. Those sort of revs are roughly transition from needles to main jets.Don't suppose you could get a vid up? Quote Link to comment Share on other sites More sharing options...
Dynamo_Delboy Posted June 26, 2014 Author Share Posted June 26, 2014 Unfortunately i cant get a vid up mate unless i can find some way of securing my pocket cam on the bike.It only happens in 2nd gear at said revs. Never lower or higher than 6-7k rpm.Im pretty sure the sprocket is fine. Ill put a pic up of that tomorrow incase im wrong.Could getting the carbs cleaned and balanced maybe help it if its fuelling? Quote Link to comment Share on other sites More sharing options...

acting_strange Posted June 27, 2014 Share Posted June 27, 2014 I seriously doubt if its the cush drive or the chain as they are in use in every gear not just second...I would start think gearbox issue....that's presuming it only does this in second..
