good guide on derestricting 2 stroke scooters

 

this one is alot better http://www.apriliaforum.com/forums/showthread.php?t=8617 and http://www.taffspeed.co.uk/page50.html i was going to write on to that guy that wants to derestrict his sons bike but it wouldnt let me post on there, and i didnt want to re write 2 hours worth of typing and retype it

 

does the bike needs upjeting like one or two sizes when the pipe and variator is derestricted?

 

if i fit a 125 carb phvb 20.5 will i still need to upjet to run my 70cc with none stock exaust??
