Re: Starting the Race bike! BSA B50

It sounds like you know the answer already, and it's not 'compression'. It did start the bike but it only ran at around 5000 rpm and died either side of 1/3 throttle. I felt that it is too lean so i re-jetted the carbs to a leaner setup B50 is fussy to start unless you've got the fuelling right. See...

Hi Mark,

not sure about differences between road and MX, but AutoCycle Engineering in the UK make MX mudguards to original spec in chrome, alloy and stainless. I got an alloy set from them and very happy with it.

Got some proper tyres on as I'm going trail riding on the TET this weekend.

Bike's going well. Rubber mounted all the mudguards, but that gave them enough slack to move around just a little, but little was enough to start clattering into the chain and giving me a hell of a fright... Resolved now.
