thanks, can't promise any high speed work on it though, but I have saved the file somewhere more secure than the "Downloads" folder
I don't know if there are many ATV's with air cooling, even cheap Chinese comes usually with water cooling and their fan is running quite often. Then again I have repaired only cheap Chinese ones, so don't know if there actually are air cooling in some better versions, but I would imagine engine size being then quite small.
My 200cc Yamaha Blaster is air cooled. The 350cc Yamaha Warrior is also another air cooled quad. Most are water cooled especially now.
Wow, really sad that you lost all your progress, but good thing that you have courage and motiviation to start over and keep going. Just wanted to throw this in: There are some crazy engines out there My brother and I are currently working on a quad with a WSP Racing Frame and a 2Stroke Zabel 700cc, a fucking beast Spoiler: Engine
