Scooterotica

Help needed
Af Stg4 Alloy kit, 28mm delly, scoot Rs pipe, std Gp150 gearing.
Scoot revs strongly through 1st to 3rd ( bout 50mph), put in 4th and it just plods, doesnt rev on, until i have to drop back into 3rd. any kind of hill kills it
Any ideas welcome
Been told it mite be pipe (Too Revvy)
Scarboro tomorrow, at this rate ill be riding there in third

If its a 200cc you could do with a 200 gearbox over the 150 specialy if its a vijai gearbox.

Sorry, its a 175 Af kit

Ye prob be better off with 200 box as it will be much the same power as standard 200 if not better...unless anyone knows if you can change 3 rd n 4th gear for sometning else..

Bang a Clubman on for the weekend.
