We all know that you can`t compare power outputs from different dyno`s. Also I spoke to Arthur at length last year while he was giving me a lift to Calais from Amiens after my scoot spat its plug out and stripped the thread, never met him before that, full time he is a motor technician I believe, but his knowledge of Lambretta engines and the tuning of them is mind blowing, most of which went straight over my head ! We were in a van following his son and his mate both riding Lammies with big TS1`s and we couldn`t keep up with them, only when they stopped for a break or fuel.
Keep on keepin on

seems like a lot of work and expense to end up with same bhp as bolting the standard kit on

Any sccoter on TV200 gearing with an engine that revs to 9,600rpm. Conversely it won't pull in third from less tham 48/50 mph. It's geared to do nearly 110mph in top so I reckon it won't pull 4th. With GP200 gears and 19/47 It would pull (possibly acheivable on the road but not sure) 75 mph in third with useful power from 45 mph, and a theoretical 98mph in top. With std GP200 gearing it would do slightly over 70 mph in 3rd and an acheivable 92/93 top speed.

About what a well built RB250 would do I think

I think all this talk about 85 in 3rd possible 98 in 4th is all academic ,I think anything over 80 on what is basically a 50yr. old commuter bike is fuxxing scary, I do like to ride my TS1 quickly, but at these sort of speeds I tend to think....what if ? I think its all about good acceleration and generally comfortably quick cruising speeds.

I'll agree with that, full bodied lammy's can go into a s**t yourself speed wobble with the slightest bump or cross wind once your approaching 90, where your weight is on the bike also makes a big difference. There's no way I would ride mine at anywhere near that on the road.
I've tried a few things to try make mine more stable including stiffer rear shock and engine mounts but it is still a problem might have to try a steering damper next. If anyone has any other ideas about improving straight line stability I'd like to hear from you.
standing mile: 118.6mph
1/4 mile: 14.04 seconds - 93mph
