1992 4bl electric start model. Advice please😁

Does anyone know if this model has any restrictors such as a reed switch like tge later dtre/x electric start models? It tops out at around 75mph. Is that normal or can i get more from it by removing any restrictions if it even has any?? Many thanks in advance

You should be okay on that model, so long as it has the powervalve fitted.

Getting more out of it will be adding on extras like pipe, reeds and head work.

@Calum ok mate thanks for the reply. Im adding a dep rear can and having the cylinder ported in the near future. And yes it is a ypvs model.

Who is doing your porting work? Make sure you get the head done at the same time. The majority of the power is made at the head.

@Calum sending it to a guy called jim bailey. What will be done to the head? Skim it down?

[Calum]

No, the squish band needs to be altered to match the porting.
