Jetting suggestion

[Drk_rider]

Ok Just about done with the 3mm Big bore blaster. Need a bit o help on where to start with the jetting. I have never had this blaster running so I dont know how it ran before the new mods. I cant read the main jet but the pilot is stock at 32.5
Mods are:
3 mill crank
Vitos BB bored out to 72.5mm
FMF Fatty full exhaust
K&N filter stock airbox no lid
Ride the great plains in Kansas with trips to Wynoka

Where should I start?

Right bend pipe would help to.

Crap meant to put that in.

Air box with no lid.

Ya bigger carb is next upgrade that is planned. Not sure which to get. Not a big fan of the kehin but airstryker seems nice.
Would like to find a nice flat slide mikuni.

try a 300-310 main and see where that puts you. prolly a bit rich but its a safe place to start. needle in the middle with your same pilot. also, pm yamaha28, hes got a 34mm mikuni tm for sale for a good price.

ooofff, there is DEFINITELY a powa increase with a right bend. the fmf is a great pipe for stock and lighly modded motors. i ran one for quite a while and it made a huge difference in low to mid power! the right bend offers a much broader power band thru-out the range. not as much down low as the fmf but from just off low (med) to high it pulls like a TRAIN!

so what are some right bend pipe options?
