01 400ex problem

Hey guys I’m new to this forum. I just recently picked up a 01 400ex and it ran good but had a bad tick to it. So I pulled the head off and one cam lobe and rocker arm was worn. I found a head and cam off of a 99 and installed it. I put the different cam in with the lobes facing down, timing mark lined up, and both lines on the cam gear lined up on the block I then adjusted the valves and put it all back together. it will not start unless I am pushing on the throttle and when it does start it revs up and down and will not stay running unless I stay on the gas. I wouldn’t think a carb problem since it ran fine before the cam and head change. Could the timing be off a tooth and still run? I’m just real stuck and any help would be appreciated.

Hello From NJ getting back in to the ATV Life

Hello

Just picked up a 2016 Polaris Sportsman 850 XP last night and looking to go riding in NJ.

I do need some help with finding how to put in a winch in her. I thought I needed a mount but can’t find one for the 2016 model however the dealer told me if I buy the Polaris (Warn) winch that I wouldn’t need a bracket.

Anyone have experience with this.

Thanks and look forward to getting to know you all!
