Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?

Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
Any help and information greatly appreciated.

I’m looking for a top end kit for a Yamaha. I would like to see how well the engine runs before spending $6-$7 hundred on oem. Niche has complete kits from $1-$2 hundred. Anyone have experience with Niche or similar Chinese companies?

I have a 2016 Arctic Cat 500 and recently noticed some oil leaking on the engine block to the right of the oil filter. It's near two metal lines going in and out of the engine block. I think one of the lines is called an engine oil line. I have a photo I'm going to try and attach. Any help would be greatly appreciated. I don't want to start tearing into the engine if I don't have to. I think maybe a gasket or something blew around one of these lines. The ATV runs fine otherwise. Doesn't overheat or anything.
