So, I got this 07' Polaris Outlaw 90 in the shop to rebuild top end and transmission. Replaced all bearings and gears in the transmission. Replaced cylinder and piston with brand new parts. Put the engine back on the frame and fired it up. Started great, but had a taping sound in the lower crank case. pulled the flywheel cover off and found the flywheel was wobbling and hitting the stator. I then replaced the stator and flywheel with brand new parts. Timing is all set on the timing marks now, but when I turn it over it kicks back when it fires and ends up stripping the starter idler gear. I've replaced the starter gear once already and now have to replace it again. Is it possible that the timing marks on the flywheel are off or maybe this flywheel is not for this exact model? Thinking of advancing the timing to try it, but don't want to keep going through idler gears.

Smells like gas in the oil ... Also, recently replaced belt, new BT does not have grooves on both sides, does that pose a problem? Also just bought and replaced new carburetor, never has it idled better, but give it gas and it backfires very loudly!

i just rebuilt the top end of a 99 Bear Tracker 250 and it can’t get it to hit off of gasoline or starter fluid. Occasionally it will backfire. Right now I’m just trying to get it to fire off without the carburetor like I’ve done a thousand times before with other engines. Usually there is no response, but occasionally I get a backfire through the intake. ISeems like it’s out of time, but I don’t see how that could be possible.
Here’s what I know:
1. compression 120psi
2. all timing marks are lined up after numerous revolutions.
3. Strong spark.
4. Valves adjusted correctly.
Thanks in advance.
hey I'm dave westfall I'm new I just became an official member of this site a few minutes ago. Ive been crazy about quads and bikes since I was about 3 and ive always done my home work on them figuratively speaking. I would say for comparison to the common man that I am pretty knowledgeable about them. its been my passion about most of my life. I love talking about quads and bikes so if anyone out there would like to talk with me about mechanical subjects or about person experiences while riding or just shoot the breeze please feel free to chat with me. I'm looking forward to it.

Hello i have a linhai 300 of the 2004+- era. I had a cluch problem so we changed it. After changing it has a hard time to start going. When you pop it into gear and press the gas it barely drives but when it starts going about 20km/h it start driving well the acceleration is normal and everything do you have any idea of what could be the problem
With this cold snap, I noticed yesterday that the battery on my grizzly was a little weak. even clicked a few times before I got it to start. I'm thinking of picking up a batter tender/ trickle charger so was wondering what people use to keep their ATV battery charged up. I was looking at these on amazon. They both have good reviews.
or this one
Kind of like this one because if the accessory plug
picked up my third timberwolf 250 for my daughters. these are great light weight little quads.
have a strange one for you. the quad will NOT start in neutral. it will start in first.
if i lift up on the gear selector just enough to hear the little click (its not loud, sounds like a contact clicking, perhaps the neutral safety switch?) the light will go out, but it won't yet be in first either. that is how i have shown my daughter to start it and she can.
id like to carry out whatever repair is needed. i have the pdf of the shop manual but it doesn't really have a flow through diagram.
any help appreciated! thank you.
i need to add something. it feels like i can switch into another gear BELOW neutral.
so if i switch to neutral, i can keep pushing the gear selector, and it has another click below the neutral. the light stays on, and when i pull up into first it kind of feels like it has two positions it moves through to arrive at first.

New ignition coil,pick up coil,stator,reg/rectifier,all new wiring.Started it up today rode for an hour shut it off.Tried to start later wont start.pulled plug wire it firing a blue spark while starter button is pressed.Tried new plug no change.
