rough acceleration from a stop

I have a 2011 SE5 limited that has a rough acceleration from a stop.I have had a Can Am certified dealer try to fix with BRP tech support help. Lots of parts changed and no results. injector,plugs,coil wires,evap canister and purge valve,hoses have been looked at. Anyone have an idea what to look for next?

Don't just look at the vacuum hoses, replace them with silicone hose from NAPA.

I agree about the hoses. Unless they bent them to check for cracks you cannot tell just by looking at them. I would also change the fuel filter out. Which dealer did you use?

I agree with have the hoses replaced. My 2009 RS was hesitating badly on starting out. Had the vacuum hoses replaced and ran great. I also had Baja Rons plug wires and plugs installed, as long as the bike was in for hose replacement.

but one should also check the intake manifold as they can also dry out and crack. Run some injector cleaners through to help fuel flow...:thumbup:

Thanks I will inquire if they have been replaced when it was at the shop
