I have a 28mm phbh carb with a 50 slide which will be going on a standard rapido classic 225 I know the the norm is a 40 slide. I will be roughly starting with av 266 x7/13 needle 300 needle jet and 55/60 pilot and a 128 main and no filter and a jl3... Will it make that much difference? Any advice would be gratefully received cheers

In short yes. Your slide has an influence on the air fuel mixture up to 1/4 throttle, the bigger the cutterway in the slide the weaker the mixture will be, could be a problem if your sitting on a open road at 1/4 throttle for a long time. My Rapido is using a 30 slide at the minute so they do differ.

cheers Jeff.

Thanks Jeff info much appreciated

will now have to go and check mine to get exact settings, but from memory think I tried with main jets of 125 and 128 with similar setup, didn't work.
Again only from memory, but think went down to a 115

Many thanks pal
