2001 vulcan classic 1500e carb rejet ?

Hi JW,

• Have you considered a DynoJet kit for your bike?
• From what you said about the needle clip position, I would guess that the stock needle has already been removed.
• A step up on the pilot will likely be necessary. The 50 with 1.5 to 2 turns out probably good.
• A 170 from a 138...that is a HUGE jump on the main.
• No doubt the flow mod you have done will require a major step up. The biggest change is the open air filter. You mean like K&N or you went full on open cell foam type filter?
• You must have a good job to afford all that gas your bike is gonna start consuming.
• You will need an assortment of jets to find the correct one. To just say "Oh Yeah, a 170 will be perfect" just isn't realistic. Jetting is a trial and error process that some find fun and others frustrating.

Thx for the info and it’s becoming more of a pain in the butt lol. I’m actually using one of them spectre round filters deleted everything else air box and stuff I maybe should of not into this haha I’m mechanical guy but with a air ratio gauge installed still can’t figure this out yet. I put a 42 pilot in runs around 13.9 or 14 idle but when I give it throttle it just is in the 17 ratio and pops like heck.. tried 4 different sizes of jets so far nothing seems to fix when I give it throttle. Thinking something else is wrong maybe with carb?

Wondering if I should just put the cross tube back in run the stock filter again just keep everything else deleted. I capped off the back at the top of carb where all the emission stuff connected. Hooked everything else up the only other line was the one to the side of card by choke but it never said cap or anything that one. It runs down to bottom of bike.

Backing plates are in sealed good so not sure. Unless I’m missing something simple I can’t figure it out. I only run bike tell it warms up then see what it does shut it off when testing. But ya throttle gives me nothing but troubles on all different main jets. Idle is little rich but nothing horrible.
