Right a club mate has a rapido barrel and brand new mugello piston, he nipped it up and couldnt be bothered running it in so bought a monza. Since then it has been cleaned up and tuned by chisel speed and produces 23bhp with the same carb and exhaust as mine. It however, was ported with a 60mm crank in mind. I am thinking of buying this for my Jet200 once repaired.

So what do people rate to be a quality 60mm crank?

I have looked at eccentric crank pins in the past. From what i found they werent readily avialible and werent really economical once the price of a jap rod and fitting came into it. Unless you know different?

From price low to high

Evolution also here cheaper

I've stuck one of the Evolution cranks in my GP to run with my Rapido. Seems like a very nice crank for the money.

Cheers for the reply, i was looking at those evolution cranks. Have you done any miles on your rapido? and what power do you expect it to make?

Also, i assume the crank shimming issues on the BGM one has been sorted? I read some of the early ones were incorrectly machined?

Not run mine mine yet, still sorting out some issues with other elements of the build and it's mostly been on hold over the winter as I don't have an indoor workspace, but I'm thinking first decent day, getting the exhaust on and attempting a start will be priority no. 1

Just done some googling. ANd the only online post i can find about the Evolution crank shafts was "Twenty Eights" snapped con-rod.... Which doesnt fill me with confidence...

I am just after peoples experience, what crank, what top end, what power and how many miles and would you recomend using said crank.

Cheers,

run many miles with tuned ts1s on one MEC 60mm crank - great price at 120 quid

MEC race - thousands of miles in a TS1 230 and now, re-rodded, in a 240. The conrod and big end that came out were absolutely mint. Crank problems seem to be confined to original Indian and 300 quid ones.

Af rayspeed have a new crack available with different configs suitable for rbs around £180.00
