    so ive got a 50cc typh 04, and read a guide online about removing the spacer inside the crankcase, when i removed the spacer the belt seemed quite slack, i took it for a test drive and the bikes bogging and wont drive, is this because i dont have the airbox or the black cover of the crankcase on or because the belts to loose or anyother reasons?

    thanks in adavance

    You followed a crap guide then and half only half de-restricted your bike. It's quite easy to fit the front pully back wrong and end up messing up everything.

    You need a box of jets from the stock size and up 10-20 sizes and then you have to go through working out what runs best. There are lots of topics about this and guides on the forum.

    ok thanks alot for the help

    could i get away with sticking the spacer back, then book time of work and get jets so im fully ready and got time to do everything properly and not rush

    That's probably the best idea.
