2005 Bruin 350cc Oil pumping into airbox
The most common reason for that oil in the airbox, and especially if it starts doing it suddenly, is that the sump is full of fuel. A sump full of fuel would also cause the engine dieng once it starts to get hot. I'd suggest checking the oil level as the first thing. A lot of bikes also have restrictor valves or orifices in their breather hoses, and in some models if that restrictor blocks up it can cause problems like the oil in the airbox. -

Aftermarket vs OEM Carburetor Comparison
It took a lot of work and rejetting but I've managed to get the Motoku clone carb running pretty damn good on my Quadrunner 250. Part of the idle problem I was fighting ended up being a fuel pump issue, there was no fuel in the vacuum line but I think there was a pinhole leak in the diaphram. After replacing it I no longer have issues with it stalling every time at idle when warm. -

Aftermarket vs OEM Carburetor Comparison
Sometimes the chinese carbs are our only options unfortunately. I have had mixed luck. On a kodiak the previous owner put one on and then sold the machine because it ran so bad. I tried everything I could think of to get it to run right and never did. Found a used OEM and problem solved. Swapping jets and setting the float is minimum. Seems like they never cold start or choke right either. have gotten carbs where air passages were never drilled. Total fail. Seems like on lawnmowers they work much better. Not perfect but same scenario, OEM is just not available new or used so you have to make something work. I was fighting random problems with a 300 bayou. Bought a chinese carb just as a process of elimination. Ran pretty decent. So I swapped jets and been running it ever since. -

2005 Bruin 350cc Oil pumping into airbox
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? -

2024 Presidential Election Discussion Thread
As cited in the Hur report, Biden read classified material to his Ghost Writer. Which means, he had them, he knew he had them and he didn’t turn them in at the time, which means that his possession wasn’t “inadvertent”. Not to mention reading classified documents to someone who didn’t hold a clearance….all those things are felonies. Given all of that, it’s not hard to imagine that those documents weren’t just “stumbled upon” and that they were actively looking for them when they were “found” because Biden knew he had them. I handled classified materials for 30 years so I am very knowledgeable about its handling and can assure you that no one “inadvertently” walks away with TS SCI documents. I have several issues with Biden beyond the classified materials issue, and therefore won’t vote for him. I have just as many issues or more with Trump. Personally, I’m done voting for someone I don’t think should hold the office. It’s a great county, and still will be after the next term is over. It really amazes me that people think that one man can “destroy our Democracy. Our system has checks and balances and they work. -

You may feel you have poor choices but by not voting you are in effect casting a vote for the one who is the worst choice. -

2012 John Deere Gator 850i RSX Idle Problem
You can adjust the throttle in the throttle body but would have to set it to about 4,000 rpm to keep the motor running. Low idle is entirely different than erratic idle (up down, up down -> dead)
