Could it be my gear ratio?

[alanscottj]

Righto, here's what I've ordered (so far!) -

GP200 Clutch Sprocket 47 tooth
Chain GP200 (ltalian) 82 Pitch
GP200 Lower Chain Guide
GP200 Drive Sprocket 18 tooth
GP200 Gear Box (SIL) 4 Gears & Cluster

Ordered from Scooter Restorations - they reckon the 47 - 18 should be fine

Do you know what gearbox and sprockets are in there at the mo ?
does sound like A GP150 ( ying, ying, ying , whur.) but before you spend all your money, it would be prudent to see whats in there.
back in early 80`s i bought a 200 engine from some one and it had a TV200 box in it with 17/ 46 sprockets !!

Saw something similar advertised locally not too long ago. The guy was convinced it'd do about 130mph with that set up. And everyone that said otherwise was a w@nk3r - as he'd got twenty plus years of experience with Lambrettas.

you would have to be mad to expect that sort of speed ,without a seriously powerfull and torquey motor of perhaps 45bhp plus

Meh.. run it in for the first 200km of the ride. You'll feel it loosen up after the first couple of hours.

If your a member of a scooter club, couldn't the members of said club have helped you to sort this issue without resorting to spending lots of money?

I don't follow, how would the members of my club be able to help the gap between 3 rd and 4th. I would always need to buy the correct gears and have them fitted. Granted, I could have paid one of the lads to rebuild my engine but I have utmost respect for Barry Turner and know that he will do a fantastic job rebuilding my engine. I am in a fantastic club with members that are always happy to help and advise
