I got a V&H ProPipe HS for my 1996 FXDL. Can any of you guys help me out on the jetting. V&H says I need to buy their jet kit $$$. I would prefer to do it myself, I think jet kits are way overpriced. I have a CV carb and stage I air cleaner with k&n filter, the engine is stock. I am considering a cam but that's not in the budget right now. Anyway does anyone have a similar setup? What jets should I put in to get me pretty close on the setup? I did a search but didn't find anything. Your help is greatly appriciated!!

Since your motor is stock,I would think either a slo jet or a needle
change would be close.And drill out the plug covering the
air screw and adj that. should be an easy tune.

You might have to up the main jet one step. ie: if you have a 180, try a 185. Your dealer will have them, they're like 5 bucks each. If you have any carb work done, or a needle change, you can change the needle clip setting. I don't think you will have to change your mid range jet, but for ideal settings, a dyno Air/Fuel Ratio check will tell. It's all easy stuff.

I pulled the bowl off last night and the main jet is a 170 and the pilot jet is a 42. I am not the first owner on this bike and with it being a 1996 I have no idea if these are the stock jets or not. I did order an 88 sporty needle for it, I have read that this needle has a better tapper to it than the stock one. What do you guys think? Thanks for the responses!!

How did the bike run before. What exh was on it ?
do you know anything at all about tuning a carb. No insult ment.
Try the needle first. Adj the screw. Start at 1 1/2 turns out.
and adj from there. What do the spark plugs look like?
I would pick up a 175 main and a 45 slo just in case.

It ran pretty good before and the plugs looked good.The bike had cycle shack slashcut full exhaust on it. I was just wondering if anyone has a similar setup and knew what jets they were running. I have been reading on http://www.nightrider.com/biketech/index.htm today and it sounds like I am pretty close. With the new needle they show a 165 main and a 45 pilot. With good flowing pipes maybe a 170. I will get a 165 and a 45 and go from there. Thanks for the responses!!

When I installed a PP HS on my 2001 Night Train, I called Vance & Hines Tech Support and had a long conversation about installation.

Their recommendation for me was 185/45 jets with 3 1/2 turns out on the A/F.

I went with their recommendation.

Call them and see what they tell you for jetting. They were very helpful to me.

I would rather error on the rich side than be lean. Blue pipes look UGLY.
Try the 45 slo & needle change first. You mite want to get the S/E
adl ign module. It would be a good upgrade for you when dyno time
comes around.

From what I understood with them...

If you keep the stock needle, go up to a 45 and one size larger then stock (175 if its a 170) for the main.

OR

If you change the needle, I think just leave the 45.

I have a 42 still, with a DJ kit that was installed before I got the bike using the 3rd clip down, DJ180 main jet, and all the other jazz they have you do to it. I start it, after about a minute or two of keeping it going with the throttle, I take off. Im running a little rich with that, since I havent found a dyno to tell me how the circuits are doing. One day I will.

I had a 170 stock jet.

Tibs, Move the clip to the 2nd notch from top.
Dynojet uses a diff calibration on their main jets
The Dj180 falls between a 167.5 & 170 mikuni jet
You also should adj the air screw.
Take it for a ride,check the plugs.
