Recommended Jetting and Needle Position???

Hey everyone.... Ive been reading around for a week or two now.... and heres the scoop. 86' VN750--- no ears, cone filters on the carbs, jardine straight pipes--- can anyone recommended jetting and needle position?? I was thinking the 140/142 with the 2 shims.... but had to think about it again due to the completely open exhaust. By the way, thats how I bought the bike.

Second question..... what vacuum lines to I need to be plugging and keeping open?? I think I need to keep the rear carb to the fuel tank..... beyond that im lost like a baby in a topless bar. Any help would be great!!!!!

Oh... and dont EVER try and cheat the system and make your own carb boots...... that was a week and a half waste of time and effort.

Thanks!!!!!!

Mike

ive got the cone filters and straight pipes and i have 142 mains and 42 pilots w/ 2 shims under each needle.... works great btw theyre effin loud w/ straight pipes huh lol i love it. btw the vacuum line on the left carb goes to the tank and the 1 on the right should be plugged. do u have your reeds on the sides of the engine blocked? does it backfire

Two schools on this, either put a marble in the big hose or get coasters. Somewhere on here is a thread for the dimensions to make your own, but I'm a little too lazy this morning to look it up lol. I took the covers off and traced them on aluminum flat stock to make mine, not too difficult.
