couple problems,

1-once the bike is warmed up if you open the throttle fast it splutters and cuts out, is this to much air in the mixture? and if so how do i turn it down?

2-spark plugs keep going at least once a month , costing a fortune now what could this problem be? and im using the right plug acording to the manuel.

3-bike will only do 80mph are there any restrictors and where?

4-bike randomly cuts out while riding for no apparent reason.

please try and answer my questions if you can i really need help

thnx
dene
p.s this is not my bike but a friends bike.
