This is the 2007-2011 Yamaha YFM350 Grizzly IRS Auto 4X4 Service Manual. This not a Grizzly 350 manual, acting like it covers the IRS, it is for the IRS specifically. The model was not changed over the 07-11 years, but the IRS has unique features, that you want specially called out in the Workshop manual. It has all the information to do a complete tear down and build back. Its a true Repair Service Manual. I have verified that is complete, and correctly covers all the years. This is the best available, I will guarantee your satisfaction. Enjoy
