Ever since I got the bike together. I have had an issue with the 49 hushang hesitating when the clutch starts to engage on my 4g belt drive setup. actually worse if I roll on slow. if I peddle more from a stop it helps but there is still a hesitation, then when the clutch engages fully it accelerates great and the engine sounds great. I am 240lb. the bike has a 44 tooth rear sprocket. could it be it is too much weight, and I need a bigger rear sprocket. or is it an clutch adjustment issue. have not adjusted the clutch at all out of the box. or is it a carb jet issue. most days I have been taking it out so far it has been around 25-45deg f. up here in ND. we are at 2800ft altitude here. any help is always welcomed. thanks.
