So i put a 110 main in and a 17.5 pilot.
didn't run good at all. so i looked around town and found 117.5 and 120 mains. i put the 117.5 mains in. it runs ok but it is popping at low throttle and runs good at mid throttle but seems slow at 3/4- full throttle.
so i just wanted to check that my thinking of putting a 115 main and a 20 pilot in should smooth things out. also the clip is on 4. the bike is a 78 kz1000 stock crabs.

You need to go up to about 125 mains
What do your plugs show?

I just finished putting the bike back together after spring break. i put emgo pods on it for the look i knew it was going to suck to tune. i saw a pdf that had a equation on it saying that you go two sizes up for pods and headers. i think the bike has a V&H pipe on it with no baffles but the tip has been cut at a angle where the label would be.

115 main and 20 pilot should get ya close....i have the same bike and stock with a vance and hines with a competition baffle....you definitely
want the 20 pilot, but since you have no baffle whatsoever, you are probably going to have to mess
with the 115 and 117.5 mains and see what works best...4 th clip is ok...i will run a 117.5 main as i have other mods, but that might change.....
as far as the emgos, you might want to gorilla glue the rubbers to the chrome...they seperate easy....i am not a carb expert nor play one on t v..but this has been my experience and what i have learned here.....good luck....keith

while riding to bike night tonight it rode like crap and my buddies said my pipe had a constant blue flame in it. so the mains are def too big. so I'm going to order the 20 pilots and some 115 mains from Z1E in the morning. i live 3 blocks from campus so i will just walk to class till they get here Monday.

You might try a stock airbox to see how many of your problems vanish.

That sounds like you need a bigger pilot jet or to adjust the needle.it runs ok but it is popping at low throttle
