I've just replaced my franspeed race exhaust to a Protti ..
I've bolted it on and used it to great gain and grin factor BUT havernt had it flat out as i hadnt rejetted until yesterday ..
Its ts230 with a 30 mm flatslide, its got a 135 main and have now gone up to a 145 ? I will be getting it booked in for a dyno but wanted to know if may have gone slightly too high on the main...
Anything related to Lambrettas... ask tech questions, post helpful info, or just read and learn.

you will not know for sure until it is on the dyno, as im sure you already know the exhaust has an effect on fuel mixture, so if you change to another type of exhaust the fuel mixture can be altered, ive known a few people that have holed a piston after a pipe change, I would just ride it steady until it has been on the dyno.
