Parked last year running. Now won’t fire. Spark good, fuses good, fuel to carb good, primer does pump into carb. Took carb off, used carb cleaner, hope got jets clean. When cranked, smells like old gas. Owned for years, never had this happen, could old/bad gas stop from firing?
Thanks
Hi,
New member here. I have a 91 trx250x that I have had for a long time. Finally tore it all apart to get it back to its old glory days. I have the rolling chassis back together and now time to look at the engine. It has always run decent, just a little oil moisture around the valve to head gasket. I took the very top section off and I’m having a hard time trying to decide if I should take the rest of the head apart to check the condition of valves or just leave a good running engine alone and replace the gasket I originally planned to.
Just wondering what opinions are since the engine is out and on the bench. It’s going to get an FMF header and silencer and a stock carb that I will jet to the pipe.

Hey guys I got a 03 predator. ..I recently rebuilt it …high compression piston new jug and valves all was well upon fire up …then starter clutch went .. (common on these )…replaced that …but when I give it quick shots of throttle it hesitates …I have cleaned the carb many times …I have moved the needle up and down and been up and down on main jets …air screw to doesn’t change this either …and ideas? …I am a good mechanic …but this one is pissing me off…only because if you go smoothly threw the rpms there isn’t a issue …just quick shots …i also have replaced the intake manifold cause old one was cracked …if anyone has had this issue and solved it please enlighten me thanks

I noticed that my bike had a fuel leak by the overwhelming smell of fuel in my garage. So I pushed the bike outside and could see that fuel was draining from the overflow vent with the check valve. So I suspected that some piece of crud was stuck in the float needle valve. I couldn’t get to it right away so virtually all the fuel drained out. When I started working on it, I thought I’d try to run the engine and see if vibrations and fuel flow would allow the debris to pass and allow the float needle valve to seat properly again. I filled tank with Stabil/Gas mix and started the bike to drive it around at some wide open throttle runs. But bike wouldn’t move. Its like the drive belt was barely engaging and would just barely move the bike in forward or reverse. I wondered that night after I had quit working on the bike if gas had gotten into the drive enclosure. So I searched the ‘net. Nothing. Today I started the bike to allow the air movement through the drive ventilation system to try to dry the enclosure if some fuel had gotten inside. When I reved the engine gas came pouring out the vent exhaust. I pulled the drain plug and I’m sure a pint of gasoline poured out of the enclosure, maybe a quart. I haven’t pulled the cover off yet. I’m dumbfounded at this discovery. I think I must be lucky not to have caught the drive on fire as I reved the bike trying to get it to move. Fortunately I didn’t do it for long as I feared I’d ruin the drive belt, so maybe I didin’t get the belt hot enough to cause a fire/explosion.
Has anyone ever heard of this?
New user here. Had to post to see if anyone has experienced this before. Must be leaking around gasket somewhere.

My brother has a nearly new 2015 500 renegade. Last week we were riding tight trails with banks on both sides. Long story short, he flipped his quad on its side very slowly. It was on its side for maybe 30 secs. We flipped it over and It was fine for the next 20 miles of riding.
Fast forward to yesterday, We went riding again. After the few miles, we were going on a fairly steep hill and all the sudden his renegade just starts smoking white which was for sure burning oil. We checked the oil and it was a little low but it was still like a 1/4” below the low line. On the way back to the trailer, It had a red light blink for 5 sec and then he said it locked up the tires and it bogged down and then quit, Which I am assuming was the motor entering a limp mode. We towed it back to the trailer. We started it when we got back and the motor sound completely normal. No ticks or knocks.
My question is, why would the oil take 25 miles to start burning? And also does the motor have a low oil level sensor to tell the motor to go into limp mode?
Looking for advice on snow plows. Looks like everyone likes the Alpine, just wondering what other options people are going with. Currently it shows unavailable on canam site, and it’s pretty pricey.
Also, can anyone tell me what kind of frame I have? G2, G2L etc..
I need instructions and specs for my 2001 Grizzly 600. I have low compression and was told that I may have a bad piston ring…or maybe a broke timing chain..or maybe something else. So in my search for someone to repair it I have found no one who is able to want to repair it. With that said I intend to try myself. Does anyone have the pdf for a 600?
