First off thanks to this site for great info. If not for the info given here and a GYT AIS kit given to me by the dealer, I would be a VERY DISAPPOINTED WR450 owner. I couldn't believe how corked up this bike was. I stepped up from 1990 WR250 2 stroke and was expecting more out of the box! I will repeat what I've heard many times over on this site YOU MUST DO AT LEAST THE "FREE" MODS TO MAKE THIS BIKE RUN CORRECTLY 2nd if your looking for a great dealer in Northern Ohio see Ralph Johnston of North Ridge Yamaha/Suzuki, (NRYS.) small dealer, great to deal with!
