and im just wondering if anyone has any information on it

its had fast road cams, racing clutch, bike carbs, 4-2-1 manifold, scorpion exhaust , lightend flywheel etc but is really tempromental its been sat for a while and i drove it back yesterday was a bit slugggy to start with but towards end of journey shifted and ran fine after half hour of running however on short trips its really slow and boggy and struggles to fire up as its overfueling

any ideas on how much it is going to cost to fix the problem ive been told it needs mapping again as it has had a new head and the old head had bigger valves in etc
