Hey guys I finnaly rode my new wr450 after I did all the free mod's, this thing is a caddy! Iam comming off a Kx500 so needless to say the WR feels like a electric machine haha...no vibrations. I rode my normal 20 mile single track loop and I had zero arm pump, where as my 500 would have my arms on fire in 5 mins lol. Oh and getting to the carb was a real pain in the rear!! Iam sure it will be better next time now that I kinda know my way around the bike. Thanks for all the great info!
