Hello All... I just picked up a 06 WR450 and this is my first 4 stroke bike. I have been riding a YZ 250 for the last 7 years and I am not sure what to expect from this bike. Last night I took the tank off and after a long battle with a short allen wrench I was able to get the throttle screw out for replacement. While I had the tank off I was going to cut the grey wire. But in talking to a buddy of mine he suggested that I should start with just the screw and see if I like it before cutting the grey wire etc. Sort of the concept of doing one mod at a time and testing it out. I understand that with the YZ timing I will get a bunch more wheel spin and higher revs. Both of which I am use to from riding the 250. What would you guys suggest? Should I just go for the gusto? Grey wire, air box snorkel, exhaust!?!? Thanks in advance!!!
