Problems again :O

So I changed my head to a compleatly standard one as my other was fooked and now my scooter starts for about 30-45 seconds then cuts out any ideas what it could be ?

 

head gasket ?

 

Just had a brand new one on and I have it running now but the top speed and acceleration is propper poor is this normal after fitting a new cylinder ?

 

crank seals.

 

what head did you have and now what head do you have

 

Just the standard one from factory and I have a moto force 50 cc head now

 

the port timeing may be different, lighter rollers and a one size upjet may help

 

Okay cheers mate

 

it will not be a massive differance so not a massive drop on rollers, if your useing stock try 1g drop
