Title: BURBLE i THINK
Post by: billy192 on July 06, 2012, 07:41:47 PM

Hi,
Took the 750 for its MOT today and failed on no split pin in rear brake arm and old numberplate was a:to small and b: no British Standard number. so all jobs will be done by tomorrow.

On the way there and back when ever I sat at lights or in stationary traffic every 6-10 seconds I heard a noise from around the air box like a small back fire (or burble). at first I thought there was a bike behind me making the odd rev noise.  I was told the bike has only done 3k since 1993.

Any ideas?

Billy

Hi Billy is it like spitting back? could need carbs setting up with vacuum gauges or even more cleaning out? they are notoriuos for needing to be ultraclean, cheers Mick.

More likely air leak at exhaust joint
