Im using a mazz crank in my 210 setup.. which i cant stop it pinging @ WOT ive just read on the SCK site that they are to restrictive for setups that rev over 7000rpm? If this is right which 60mm crank would be best for my 210 with evo 2 reed setup? Ive tried retarding the timing up jetting the carb using a lower compression head

I can't see how a full circle crank could work well at all using the original inlet position.
The crank is an obstuction to the flow even with a cut crank with a full circle its 360 degrees. Virtually any other crank will allow more gas to flow .

Ive ordered a worb5 lip style for reed 60mm crankshaft, the one with the welded pin was out of stock do you think it's needed for the pin to welded??

I'm using a mushroom type one (60mm) and I'm getting a lot of problems because, presumably, lack of precompression.

ive changed my crank to a worb5 lip style crank no more pinging i cant wait to see how much power this makes,

It's nice to hear that.

Regards.
