If it has an oil pump and auto lube then, you can probably move the oil injection pump's control a little and check the smoke increases as you rev it a bit. The pump probably has a bleed screw/bolt too for bleeding the system if it's been dry. You could undo that and check the oil's getting through.

And the last and best way is to drive it and look back every so often and check there is smoke..haha.. More smoke after a bit of boosting and less when it's just ticking along.

I'm not familiar with that bike but if you follow the oil lines from the oil tank down to the motor, you will I think find an oil pump, under a cover, but pretty easy to access for bleeding. Most of the pumps are controlled by a cable, and if you pull the cable a little it should increase the amount of oil going in, and make more smoke. There's also likely to be a scribe mark on the cable's wheel to be used to adjust the pump to the throttle setting. Best read the manual to check what that mark is meant to line up with, and whether it's at full throttle or idle.

I also recommend mixing oil with gas, pumps fail and then engine seize, but they have been around for a while and seem to be reliable, you can check it by unhooking the oil line from the carb and measure how much it is putting out, but only after you have put premix into your ga tank. tank.

      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?

      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.
