Gearing question

[rosscla]

Just got my latest box of bits in for my rebuild and found, like a muppet, I'd ordered a 46T crownwheel instead of the 47 I had before...

This is for my GP200, 80's stage 4, AF flywheel, fresco, GP 200 box, 18x47 (5.22). Last time it was running it pulled like stink with a fairly good top end cruising speed. I'm thinking of upping the carb from the upjetted 22 to either a 25/26 mm or using the phbh30 I've got in the shed.

My question is do I bite the bullet, admit I'm a tit , send the 46 back and get the right 47 or do I get a 19 front and up the gearing to 4.84 - will it pull this?

Any thoughts?

The 46 will mildly raise your gearing from standard. A 19t will raise it more yet.

If it can't pull the 4.8, I'd consider sending it back for a better tune. Unless you're a bit of a tubby, obviously

[rosscla]

Yes, definitely a bit tubby... :bigsm:

get a 47 mate.

it will probably be ok with the 18/46, thats 5.11
