I've read that with the dynojet needle you don't need to shave the spacer, but since mine was only shaved down only about 1/3 of the way, it fell in between two "grooves," making it only slightly deeper than what would be a half-spacer with the stock needle. Since it was running great I didn't change it but kept the original needle just in case I need to go back. I might be running a bit rich b.c. the muff has deposited a bit of black soot on my rear brake arm over the past three weeks, but the smoke itself comes out looking clear.
I am getting a shipment of jets in soon and thinking of going up to 150 for the main and maybe a 52.5 for the pilot (the one with the holes). What do you all think? Should I go back to the original needle and not use the dynojet?
It sounds like it is running fine and so maybe I shouldn't tinker with it. I will enjoy the sweet music of the exhaust now rather than worry! Here are the jets I ordered that I may experiment with:
MIKUNI PILOT JET BS30/96 #52.5
MIKUNI PILOT JET BS30/96 #55
MIKUNI PILOT JET N151.067 #52.5
MIKUNI MAIN JET N100.604 #150 AFTERMARKET
MIKUNI MAIN JET N100.604 #152.5 AFTERMARKET
MIKUNI MAIN JET N100.604 #155 AFTERMARKET
With the Dynojet kit, the needle is completely different than stock...It isn't just the clip positions (which do what the spacer change does), but the taper of the needle is different too.
You might notice that the main jet doesn't have the same numbering sequence as stock. As well, the main jet and the needle work together. Changing one does affect the other.
Since you invested in the Dynojet kit, I don't know if (or why) you want to bother with the other jets. You should be able to just ride it now....
