Ok i am not quick to jump on a forum and post a question without doing my own part and trying to research and solve the problem myself but I cannot find any definitive information anywhere about my problem. I have a Big Bear 350 that I picked up very cheap which had been sitting in a field for years. I am not new to building wheelers but this one has me beat. After rebuilding top end and replacing the carb it fires right up. The vin has some number worn off from being next to the shifter but from the parts in the clutch i assume it is early since 87 parts seem to be the only ones that match. Thats when the plot thickened.
Reverse works fine but when in the forward gears it would not go past 1st and was hard to get into neutral. ie. a it took a million clicks up to thump into 1 and as many down to find neutral. still never getting past 1st. within minutes i could hear metal screeching and whirling around in the clutch side of the motor. I took the cover off to find that 3 out of the 4 springs on the centrifugal clutch had broken and were shredded. Also the black mechanism that the pawl on shift shaft grabs moves was loose so it wasnt always grab to change the gear on the transmission. I tightened that mech, and replaced the springs assuming it would solve the problem since the gears were not actually changing from the lever and the carrier should obviously not only have 1 spring left.
After putting everything back together it did go into 1st fairly easy but then i again couldnt get it back to N without a million clicks down and couldnt get it to go past 1st. I did one time get it into a higher gear who knows what one but i gained some speed and dropped rpm.
If i jack both the front and the back wheels off the ground and run the motor it becomes much easier to shift and i can get it to run through the gears pretty well. Usually going into N without a huge fight. not perfect but it does hit neutral and roar while spinning the wheels instead of gain rpm and with the power.
I have tried every possible position on the clutch adjustment screw without any noticeable result. I think this could potentially be where my problem lies at this point.
does anyone know if the case is supposed to be threaded? because mine is not. obviously it seems as though it should be since every other bike ive touched has been. i even took the cover off my quadrunner to make sure it wasnt crazy.
when the screw is adjusted and the jam nut tightened the screw will just slide back out since there is no threading in the case. accomplishing nothing.
Does anyone have any insight on any of this? Are my plates stuck, Centrif clutch worn out, case stripped or something else crazy im over looking?
On Wednesday, September 18, our ATV was stolen from in front of our house after the locks were cut. This was around 2-3:15 AM.
We realize the likelihood of ever finding the four-wheeler again is slim to none, but we had to try and put the word out there. We have put countless hours in to restoring this Banshee. It was more than just a passion project, it also was our investment for a down payment for our future house. We are devastated and beyond heart-broken. If you see any suspicious postings on Facebook Marketplace, Letgo, Craigslist, etc., or have any other information, please contact us or the Prince William County PD.
*Update* We received a tip last night that it was possibly posted on Facebook Marketplace around 8AM yesterday morning with only pictures of the front and of the back of the ATV. The description only said: PM for more details. This came up in someone’s FB Marketplace feed that has it set for a 50 mile radius from Hartwood, VA. She also has her feed set to automatically translate everything into Spanish, so It could also possibly be posted in Spanish.
WHAT WAS STOLEN:
2004 Yamaha Banshee YFZ 350
White plastics with bright green and pink graphics/stickers
Prince William County, Triangle, Virginia
$500 REWARD FOR INFORMATION LEADING TO RECOVERY. BONUS FOR CONVICTION.

I have a 2001 yamaha yfm350x and it has a brand new top end, new carburetor (stopped the leaking problem and is now getting gas to it), new CDI box, new stator, handlebar switches work, off-and-on switch works, new starter solenoid (works), new neutral relay (works), ordered a new Rectifier on its way, good strong blue spark. Has compression, valves are right. Timings is right and is TDC. When I try to start it it just makes a loud popping noise like its backfiring but it's not because its not running when I push the throttle all the way and when i barly push the throttle it try to start but won't, so I'm trying to figure out what could be the problem not starting now, Getting very fustrated with this thing and put some work and money into it and it's not still not working. This is the only atv I ever had that I can not figure out the problem to get running. Need help please..

I have a 1988 300 Honda FourTrax, All wheel drive.
My brother and I were fixing up this quad. We put a brand new battery and fuses in and it was running fine until we put the quad into reverse. As soon as it was put into reverse all of the electrical cut out and power wasn't making it to the head unit anymore and both of the brand new fuses popped. We figured there might have been a short from the starter or solenoids, but they are all working properly. At this point we don't know where to start looking for where the short could be. I'm just wondering if anybody has had the same issue or knows of similar issues that could cause these electrical shorts?

Not satisfied with the commercially available versions, Jonathan recently built an ATV spring compressor.
In this video, he demonstrates using it to remove & re-install the spring on an ATV coil-over shock absorber.
Mistake in video - the coil-over shock is not quite a McPherson strut.
If you are inspired to build your own spring compressor, feel welcome to use any ideas from this video.
Thanks for watching! Resurgence Small Engine Inc.
