Hey guys and gals. I hope you're all doing well. I've got a 2005 Blaster with a fresh top end I'm trying to get running right. It starts, has 120 psi compression (according to my cheapo gauge) and it runs and rev's up fully. BUT, it definitely smokes more than it should be. It has the following mods:
Vito's 240 Big Bore Kit
K&N Filter with open Airbox
FMF Fatty Pipe and Powercore 2 silencer.
V-Force Delta 3 Reed cage.
Half inch reed spacer.
Converted to premix runs 32-1.
Followed the jetting instructions that came with Vito's. It currently has a 280 main jet. For the initial break-in I had a 320 main and it smoked a LOT when revving up. Dropped down to a 280 still smokes when revved up though not as bad. Smoke looks whiteish blue depending on how the sunlight is hitting it. I'm at 0-1500 feet elevation where it rides So-Cal desert. I have a few theories but wanted some more expert input.
1. Crankseals are bad. But the smoke doesn't smell horrible, mostly smells like oil/gas and like I said when the light hits it it looks more blueish/dirty white not snowwhite or anything.
2. I'm still too rich on the jetting....but...280 doesn't sound too rich to me given the mods. But I could be wrong.
3. The gas/oil WAS mixed last May. Will 5 month old gas and oil (the Premium Formula K12 stuff from Maxima.) cause it to smoke like this?
Well thanks for any input you guys with more experience with this than me have. Thanks everyone!
