Hey guys,
I am going to beat the jetting question to death again in another thread. Nothing I have come up with on here has helped much. Here is what is going on.
Bike:
FMF Fatty pipes
Vforce 3 reeds
105 psi in the cylinders(yes it's low)
K&N filter with stock air box vented
Conditions:
Elevation: 2700ft
Temp:45-55 right now
Dry air too
I thought the bike was loading up on the bottom end. It had a bad bog if you gassed it hard. So we took out the main to see what is was, a 260. We then put in a 250 and lowered the needle and picked up the idle. This made the bike run like crap. It would hesitate bad and have no power. Took the tops back off and raised the needle two clips. This cleaned up a lot of the part throttle hesitation. So we thought it needed more fuel all around. Put in some 280's and now you are lucky to get it started without the choke on. Has the same huge bog on the bottom. The top screams though.
I need some help here. I thought a 280 on a basically stock bike was way to much up here at our elevation. I guess the 260's are going to go back in and just be happy with that. Get the motor rebuilt too. New plugs were also put in. Ran it wide open on the 280's down the road and the only carbon on the plug was on the ground electrode.
Help me out here fellas.
