Gearbox failure

@lllDennis Best jetting for Athena 170 is 300 main jet on the
Mikuni tm28 but with the powerjet blocked off. Just cut the
rubber tube in half from the float chamber to the powerjet then block the 2 halves of the rubber tube with a couple of 5mm threaded bolts or similar.

@calum Any recommendations on a crankshaft? While everything is open I want to replace it anyway (Has some small grooves where the bearing is). Best with original or aftermarket?

@llldennis Didn't know they do aftermarket cranks?

@calum

There's some on ebay for less than £200

@calum pretty sure they sell the aftermarket cranks on PJME as well

@jimmydc98 Cheap

That's good to know at least. Connecting Rod for my RS is that price alone
