Scooterotica

Thinking about building a GP street racer with a TS1 225 engine I already have and was wondering how far can this engine be taken performance wise.
I am thinking about out and out acceleration and high speed suitable for road use, not really touring more short distance.

Hope this makes some sort of sense to the technical minded out there.

Thanks for any help you can give.

As far as your wallet is deep

Asked for that I suppose

Was thinking more along the lines of 240/245cc with the best carb/exhaust etc and what BHP it would give.

Thanks

Not as much as you'd think,
How about 37.9hp peak @ 8200 and over 30hp from 6400-9200rpm, 25ftlbs of torque from 6400-8300rpm.
Ported TS1 225 barrel, standard size transfers at the base and matched to the case, 34mil, Franspeed Race, 58mil crank, electronic ignition (static timing), MB 6 plate converted to 7, VForce reed block.
As there was no welded up casing with huge transfer feeds and in return no welding to the barrell or a re'line to pay out for it kept the cost down. And keeping it a straight 225 helped to. It also depends on wot engine or parts you have to start with. This wasn't the limit on this engine and could have been took further.

Hi Chris thanks for the info.

The engine in question as far as I know having just purchased the scooter is a standard TS1 225 with 5 plate clutch running GP 125/200 gearing, 34mm Amal carb and a sterling exhaust. Not had time to have ride on it yet but it will be getting rebuilt into hopefully a rapid scooter. Just wondered what the options are with lets say money no object but has to be rideable and reliable .

Thanks again for your time.
