I just bought a 2010 yz450f the bike has been set up with a enduro kit. I took it on a trail ride yesterday and it was misserable. at idle in 1st gear the bike was just to fast. I would constanly have to clutch it and must have killed it 10 times. The gearing has obviously been changed to be more street suitable than trail. I live in Tahuya WA and ride tight single track 90% of the time. I bought this bike with the intentions of having it be a 4 season bike as I have also purchased the Timbersled kit for it. I guess what I need help on is what shoud my front and rear sprocket be? I like to be able to go slow in first and realy lug it down. I have read alot about these tuners and sounds like I should get my hands on one but I can not afford that until next year. I am new and tried to search this bu had conflicting reports. I am not sure that it matters but the bike has a full FMF 4.1 on it. I also noticed it's super jumpy off idle but I realize I am not fixing that issue without a tuner, so I'll learn to live with that for now. THanks Jason If any of you are local to me you may know the bike it was a race bike for Leon Capps he recently turned it into a enduro. It was at Brother Powersports in Bremerton. I Sorry I am such a bike moron I have been riding a clapped out XR400 for years, this high power bike stuff is all new to me. oh I think the gearing now is 14 front 47 back. I did get a 13 front in a box with the bike I have yet to install.
