Sure could use some help. 95 inch twin cam softail . branch heads larger valves screaming eagle ign 44 mm cv carb. vance and hines pro pipe . I have tried 190 195 200 205 220 main jet. the bike runs great till wide open throttle then it cuts out around 4500 rpm and will clear up some after 5200 rpm I have moved the needle frome top to bottom. if I put the 220 in and raise the needle to the last slot I can get the bike to run great on top end but jerky in the lower rpm range. this bike has 590 lift cams with 248 dur. roller rocker arms . makes 185 compression pleas help Thanks.
Whilst I can be jealous for your expenditures, I pose another question for the Gurus:
05' TC88, Stage 1 air filter with SEII pipes, baffles modified by me for better backpressure and, ridding them of the assymetrical beer-can slash that forced air to one side of the pipe to enter the outer chamber, and using cones I built, centered in the pipe, force gasses symmetrically into a circle of holes leading to the outer chamber, other gasses passing the cones go down the center: led to more torque.
Then, Andrews 21 torque cams and carb mods.
I DO need the 48 jet, have gone as far as 50, but came back. Sportster needle with one washer beneath. Original stock mileage was not great, 36 city, 42 hwy, and is still the same, but with massively better performance.
My stickler is this: it used to pop a lot, now does not, absolutely LOVES higher elevations, getting as much as 47mpg in the twisties with the hammer down. What boggles me is, at about my 1000rpm (I guess) idle, it sometimes just "misses a beat" and STALLS, often at stoplights. It idles best at heat, and will stall more easily at cold running, after the enrichener pulls itself back in.
Leaner pilot won't work and the 50 didn't help, so I backed off to the 48, and overall, this is one freaky great bike to ride!
. But then again, I really like my new one too
