Final drive.

[10 inch Terror]

Hi all,
I'm thinking of fitting a Jolly Moto pipe to my RB20 and it's recommended that the final drive is 5.0 for the pipe to work best. My current set up of LI150 Pacemaker box with 17/46 sprockets gives me a final drive of 4.98. My question is will this be close enough or is it miles out? I don't really want to strip the engine case to change things if I can get away with what I've got. Any advice very welcome. Thanks in advance Pete.

It's about 0.4 % difference, I think it will be fine.

Nonsense! Don't run it like that or you'll blow the thing to smithereens!

Sorry, that wasn't very constructive.

Like rosscla says, you'll be fine with 4.98.

On a par with a 200 kit actually only being 198cc.


As Hendy will vouch that 2cc could make a world of difference.

Depends where you put it...
