Its a 2wd yamaha timberwolf 250 from 95'|||I could not find a Service/Repair manual Online to downlload for free.
But Yamaha Does have an OWNERS Manual.
It's awkward,,,because it's Huge due to being printed in several languages.
It wont tell you how to actually REPAIR anything
And it's NOT Printable,,,nor editable
You cannot cut out the stuff ya dont want/need ,to create a more streamlined manual
But it does have a bunch of useful info,,,and a pretty good "Routine Maintenance" section
Ebay has Clymer's,,, and Haynes Books,,,,about $30 or so
They also have Manuals on CD for under $10
Here's an example
YAMAHA TIMBERWOLF 250 2WD 2x4 REPAIR SERVICE MANUAL CD
You get all 3. The Service Manual, the Owner's Manual, and the Parts Manuals.
Check it out,,,sounds like a heckuva deal for $8 to me
Hope any of that helps,,,Good Luck
