OK, sooo I finally did the old skid plate and screen removal to clean out my oil sump during an oil change... This bike only has a couple thousand miles on it. Runs like a top still... Very few issues over the years after buying it used.
But boy I wasn't expecting to see this! Piece of a circlip, stuck up in the screen, and a another shard of metal and maybe a piece of gasket material. Nothing in the oil but that... Pristine otherwise, and still runs like a top. Always has.
Soooo, is it a wrist pin clip? That's the only thing I can think of like this that could end up in there. But definitely wanted to throw it out to guys that have seen the innerds of these more than I have.
The valves on this thing are still within the factory spec even. Been a really good lil workhorse...
Any other ideas?

Hello everyone, i have 2000 Polaris Trail Blazer 300 I’ve been stumped on for weeks. I’m having a lot of issues starting the quad. I cleaned the carb spotless because I thought it was a carb issue and bought a new fuel line because it wasn’t getting fuel. The carb gets fuel perfectly fine now but it won’t start. The spark plug I a little worn out but it’s good enough for just one start. The only time it does “start” is when I spray starter fluid into the carb. But it never stays on. It’ll start for a bout a second then just die out immediately even if you’re giving it some throttle and the choke is on. I have no clue what I should do. If you need more information, have questions, or have any slight idea what the issue would be and how I could resolve it. Please reply ASAP. Thank you.

I have a 2000 Arctic Cat 300 4 wheeler. I have been having some carburetor issues. So i bought a new carb. Now I'm having these issues. The unit will start and idle fine, when i go to accelerate it wants to cut off. So i checked to make sure it was getting gas and the fuel filter will be full of gas and then once the carb opens the filter drains down and will not refill quick enough to run. So i checked to make sure gas was flowing to the filter and it is flowing fine through the line. I remove the filter and run the gas line directly to the carb and the engine idle fine and then it will run good as i ride it for about 10 minutes then it will start with the same issues again i cannot accelerate enough to move the 4 wheeler. Every time i accelerate the unit will cut off. What is wrong with this thing. My 400 Arctic Cat is doing the same thing except it will backfire, I'm lost i have tried everything i know to do, what am i missing here. Thanks for your help
I have a 1999 Yamaha Big Bear 350 4x4 trying to get fixed up so my grandson can go out in the woods with me.
We have owned it over 10 years. It got harder to start, until it finally would not. Replaced the carb. Right afterwards, it started and ran nicely, but after turning it off, would not restart. Tonight I used starting fluid and ran, then died. Adjusted the idle up a little, used more starting fluid and ran great. It idled about 15 minutes. Turned it off, and restarted. Ran it around the yard about 5 minutes. Turned it off, and would not restart.
Any ideas or suggestions would be greatly appreciated!
I'm having a problem getting a CDI unit that works. The parts list calls for a 4XE-85540-00-00 CDI unit. The one currently on the ATV works but there seems to be a problem with the spark advance curve. It will idle fine an rev. to about 1.5K then starts bogging down sputtering, popping and basically running poorly. If you can get it above 2200 RPM it runs better. I have ordered and returned about 5 replacement modules that will not work at all. The unit currently on the bike has no part numbers or identification other than a Mitisibuchi logo. I am wondering if anyone else has experienced similar problems with replacement CDI's and if so what is the fix? So far I have not found a replacement CDI that will supply an pulse to the Ignition coil.
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
I have a 1994 Kawi Bayou 400 which had been running well until it sat for about a month. I left the carb dry while it was park and the temp had dropped below 0C in this time. Pulled it out last night to go for a ride and it fired up just like it should but noticed when I started to head down the road I could hold it to the bar and it didn't seem to accelerate. Lower gears weren't as noticeable but 4th and 5th it just seemed to have no acceleration and half or full throttle made no difference. if I tried to go into 5th gear with any throttle it would stall. I turned around and just poked home very slow and it seemed to stay running but this was between 15 and 20 km/h max.
I have taken the carb apart and it appears to be clean and nothing stood out on inspection to have dirt or ice. Is there something I should dig more into?
I have checked the plug and it appears to be sooty with easily rubbed off carbon. I plan to get a new plug today and test.
compression with the throttle wide open is 175 psi.
I have opened the drain plug in the exhaust thinking there could be a mouse in the exhaust or something but no difference.
I do find the engine is tickity compared to my 2000 Honda but I am not sure if this is just me looking for issues or if it has always been this way.
If anyone has any insight I would appreciate it.
In the last 6 months I have done new oil and filter ( mystik synthetic)
new Peak RPM CDI
I have noticed the fan comes on more often with the new CDI, could this be a program thing?
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.
