It lives 😁 ........after everything it turns out it was the bloody petrol , took out a mortgage an got a jerry can full of Morrisons finest premium fuel .....bike fired right up , used 2 full cans of E10 trying to get this bike to run an nothing 1st can was a couple of months old but the 2nd can was fresh that's when it tried to fire but just burbles an backfired so guessing it doesn't like E10 fuel .......thank god I never put the cheap stuff in the gsxr . Anyways thanks to all that replied an the suggestions greatly appreciated 👍 hope all are well and stay safe out there ✌️
