I have converted my bike to a single 41mm Fish carburettor in place of 2x 39mm Mikuni carbs. and first dyno run was pretty good except for rick idle and part throttle, WOT wasn't bad for first go. Great torque better than stock and only 2hp down at peak and no big drop off even at the rev limiter.
I have got the Idle and part throttle behaving and have cleaned up the small plenum area blending from the flange to the runners.
Now before dyno session 2 Should I fit a spacer under the carb to increase plenum volume or fit the cams I have from a later version that has more valve lift or both?
The goal is making more power than stock at all revs with the single Carb.
Am I missing something I should try?
