setup is:
421 serval as cast, brand new.
pump gas domes from redline cut for this setup
.050 squish, 152 psi each hole
cpi sb inframe pipes
stock cages with boyesen reeds
wicked billet intakes(sealed to death with 1211)
passes leakdown 6psi for 8 mins zero loss
35mm pwk carbs 55 pilot, cel 3rd/4th clip, 175 main(float hight checked, everything inside spotless)
700 ft elev. 70-80 degrees
San Diego, CA
All genuine Keihin jets
Now this is about as basic of serval setup as they come minus the reeds. I bought the carbs new from fast about a year ago, and from the day i got them they have wanted retarded huge jetting or bike is way to lean(ate a set of pistons to find this out). It jets out like pwk 39mm's, I've checked more than once and they are 35's.
Now a bit of backstory the motor i had before this was a passion ported cub, neverending problems including the jetting being crazy. With that setup it ended up running good finally with 175 mains, dgk needles on the 5th...yes 5th clip and 55 pilots. I assumed it was something to do with the retard port job that cub came with.
Well now im running basically the same setup as tons of other people, and I'm having to use Huge jets, even compared to a friend with the same identical setup minus reeds and his bike wont rev out with anything over a 155 main, and smokes like a banshee. Mine barely smokes with 175 mains, 55 pilots.
I know my way around this bike pretty decent, but it makes no sense and feels like there's either something wrong with the carbs or possibly reeds. Now i suppose as long as it jets out and runs good it shouldn't matter, but it bothers me. Has anyone else ever seen anything like this?
Sorry for the long winded post, and thanks in advance for any insight.
