Cleaned carbs. But 2 cylinders are running way richer than the other two which are lean. All coils and wires are within ohm spec. Battery fully charge. Isles rough and has had rejected by previous owner. https://cimg0.ibsrv.net/gimg/cbrforu...6e481424b5.jpg |

Yes I've done the gas bowl test.. pretty similar to each other but the one running rich was fuller than the rest which were pretty close to each others. Got a compression tester coming today fingers crossed so will post the results later on. Also some new spark plug coming. The 2 cylinders running rich and are very yellow spark plug is maybe because I have it beans to you as the systems out as it was sat for many years from previous owner

Good looking bike matey ,and worth getting it running right, maybe as your doing a compression test might be worth whipping the carbs off ,giving them a good clean and checking the jet sizes

I've stripped her down again the jets are 38 and 110 I think there stock at 35. 105 not too sure.. so do I need more air like an exhaust mod and air filter to composite I'll post more pictures later 😉😅
