hi mate i need a lot of help to make my bike goes 80mph and if any people know how to do could you write a list of parts needed to hit 80mph cheer
your avatar is a smidge to big and for 80 mph,the cheapest way is to drop it off a cliff. other than that you need to spend a LOT of cash on it
Pretty much can't be done on an AC. On a LC you will be looking at £2000-£3000 worth of parts.
now back to the question in hand (whole idea of this forum was to not say buy a 125" every 5 mins) so you will need both gear ups, a good crank/bearings/new waterpump, atleast spend £180 on a 70 kit, decent pipe, 25mm carb and match the lot. the case will need matching to the barrel as the transfer feeds on the proper 70 barrels are alot wider. also the stub needs to be matched along with a little case work to get the most out of the barrel. this will see 85mph
