Hello, i repaired a few month ago an old ATV a kymco MXU 250 (2004) is not so difficult, just need some money, manual instruction and some hours.

1) check the noise without the rear wheels and if necessary repair the rear axle on (see video)

2) have good tools and specific grease and a friend to help you maintain the parts, a very good friend ๐Ÿ™‚

3) have a bearing puller

have a good trip with your ATV, now new project an old yamaha big bear 350 (1999), all information and advice are welcome ๐Ÿค—

Thanks a lot

Big Bear 350, that should be a fun project, depending on the state of disrepair it is in. The Big Bear was introduced in 1988 to compete with Hondas 4 Trax 4x4, it was Yamahas first 4x4 ATV, it was produced for 1988 to 1999, they were tough as nails and along with the Honda set the standards for 4x4 ATVs. Did not have a very fast top end because of the low gearing, they were made more for work and hunting and boasted pulling power of 900lbs.

it's seem a good ATV, but a few parts are expensive and became difficult to find it.

Now i need to find the repairs manual for check all parts.

first cleaning carburetor and change the nozzle too big 130

That a new challenge for me, and if it the better i will sold my kymco MXU and keep the big bear for hunting and farm work.image00000016.thumb.JPG.baea0ff4ff72585d75fbca9eef14ceed.JPGIMG_2904.thumb.JPG.3e60e4b578acf0cf426dcbf5591115fe.JPG

Yes,I like to see the old bikes restored and hear them rev back to life. Atv where you can't go by truck you can with those little buggers. Like to see pictures when restoration complete.

Indeed it seems in good condition, but already some surprises in the dismantling. Welding to be done on the luggage doors and clutch adjustment
and the carburetor was too rich. but nothing insurmountable for the moment :-)
