Gilera Stalker 50cc problems

[mazzda-007]

Hi guys hope somebody can help me.

I have a gilera stalker 50cc moped twist and go, i have put a leo vince zx exhaust on it and upjetted from a 53 to a 60 jet. i have a crack in my exhaust which i am told will need welding but as i dont have a welding torch this is prob not an option.

1st question is there anything else i can to de-restrict my bike as it is only doing 40mph on a push

2nd question how do i repair the exhaust without 1 welsing 2 buying a new exhuast?

any help would be greatly appreciated. thanks

Its a 2 Stroke. You need to get that exhaust welded. Any decent garage should be able to do it for £10.

If you are derestricting this, then there might be a washer in the variator however if its already doing 40 then I doubt it. To be honest, thats all I would expect out of a de-restricted 50cc engine. Have you done your rollers and clutch springs to match the exhaust?
