rejet?

ok, got a carb cleaning comming up. thinking of ear shave when I pull the carbs.

I have read different opinions, but will a re-jet be needed on stock exhaust?

While I will agree with Slim and wmsonta, I will state that I rejetted at the same time that I ear-shaved with stock exhaust (even though I went to V&H cruzers shortly after) and I didn't have any adverse effects. So if you are thinking of going to an aftermarket, freer-flowing exhaust in the future, it could save you a little head ache by rejetting while you have the carbs out.

I kept stock jets when earshaved, but using resrtictive exhaust....
....Bessie ran fine....

I installed/fabbed 2 fishtail straights with baffles,,,,It seems like Im needing a "one up' now on jets....

Picture it this way....if you increse yer in/out, you need to increase flow, ie jets....

if you run a stock, baffled exhaust....then no need....the earshave will add more air, and therefore burn fuel more efficiently with the backpressure you have....once you open that, you need to fill the void with fuel, else will ru way lean....

Do the shave....add cheap pods like Emgos....and after 300 miles check the plugs...that will tell wht else to do if needed....

After doing an earshave on my stock exhaust bike my plugs were white and my front exhaust pipe slowly yellowed.

Changing my slow jet to a 42 stopped the problem but it may have been a bit too much. Currently I'm running 142/42 w/ 2 shims. On my bike I suspect changing the pilot jet to a 40 would give me the perfect jets.

Either way with my bike running 142/38 (stock pilot jet) defiantly was too lean. Every bike seems a little different.

....my bad guys....I should have added that I degoated with the earshave....that would help eliminate the lean....sorry....(tail between legs)....

I rejeeted when I did mine too, but I didn't do the typical earshave, and I also knew i was going to straight pipes eventually as well.
