beta rev 3 knock under load

[zaccyboy]

Hi iv got a beta rev 3 on a 2003, when I put her under load ie up hill climbs the engine knocks, could this be a fuel grade prob or

timing? I use unleaded but Iv read that Beta's like a higher grade fuel to run better, any experiences on this? Re timing any views on this?

Thanks

Same bike - I cured the problem by using Shell V Power.

Does the bike knock when you let off or back off the throttle or when you twist the throttle on?

my 2003 rev 3 will only run knock free on super unleaded ( doesnt matter what brand) i run PJ1 silver fire at 70.1

Lift the needle a notch. Clean the carbon from the head and piston top. It helps but doesn't eliminate it.

Billy T - The knocks/clanking is when throttle open, I also wondered if the prob was merely the engine was at its max!!!! I will try higher grade fuel at weekend and keep u posted with the results

thanks guys
