First I would would just like to say hi to everyone. I'm new to TT and to atv scene. I just got a 2005 SE 450 YFZ and looking for place to ride, some friends to ride with. I live in Swartz Creek, Mi. can anyone help.
I have 450 yfz 2005 with less then 1 hour on it. After riding it for the first time I was so disappointed on it's low end and overall performance. After asking around I heard that exhaust and rejetting makes a world of difference.
So this is what I did.
BUB Moto C4 Carbon Fiber/Titanium System
K&N Proflow w/o lid
175 Main jet
NCVQ on 7th position
Stock pilot 4 turns
About 825ft above sea level
It still lack in the low end and runs a little rough. Any suggestions?
Also while doing all this I unhook my tps (throttle position sensor), and now I'm not sure if I hook it up right? HELP ME PLEASE!!!
