I posted this question in the classic section, I suppose I should have put it here.

I have a totally standard 1958 Greeves Scottish in road going trim. I intend to make a few modifications to improve its off road use. My main concern is what gearing should I be using? Oh, it's a 9E 197cc Villiers engine. It will be used in easy route club trials.

I also want to change the standard exhaust to a lighter more robust type. Are there any off the shelf bolt on systems available for the Greeves?

Thanks in advance for any information.

Many thanks SJL

Hi SJL, if the bike as the orginal standard gearing it will be to high.This is what i would recomend;18t primary gear,13t front and 60t rear sprockets.If the exhaust is the villiers cigar type and its in your way your options are limited,there is a wes available and the front pipe youll have to try villiers services , he will sort you out with your gearing aswell. Ive built 2 9e engines this year and the go well but they have been worked on !!

All the best, Anvil

Thanks Anvil.... That is exactly what I needed to know.
