u want to get a sport 70 kit, will notice a BIG difernce then, and if set up properly with the correct carb set up and transmission will last forever...
Cheers lads im considering 70ing it but id rather wait for the top end to go (probably quite soon lol) before i put it on as it gives me a reason to strip the top end anyway my mileage is nearing 11,000 now and its a 57 plate lolololololol already had new main bearings
