jet sizes for straight pipes

Hey all,

Just put set of custom straight pipes on my 99 vn750. I don't want to go through the trouble of taking the carbs on and off just to find the right size. Any suggestions? Altitude is whatever Illinois is and its binge stick other than pipes. Thanks

My suggestion is to put the stock pipes back on. You'll never make the bike run better with straight pipes....all you are doing is making more noise.

If you do an earshave.... You will have to re-jet and will
Have to remove the carbs to do so.

Our 86 came with straight pipes and no mufflers. I took them off because we never could get the bike to run right. Nor could the previous owner.
Have Vance and Hines on 2 bikes with no jet changes.

Mine came with the exhaust butchered and it has been a pain to get the pipes the same length not to mention all the quirks etc. this causes and the backfiring...but as long as you haven't increased air intake (ear shave or K&N filter) you need to go up one step on pilots and mains may even need to shim the needles with one shim each. it is possible to do the pilots and mains with the carbs still on but it isn't easy at all and you will need to remove the front cylinders acct in order to get full motion on an offset screwdriver.
