i can get a pilot jet easy and since i "been in there" it shouldn't be too bad.

thanks

Yes....
per BriMan
The pilot controls idle, up to 1/3 throttle.
The needle controls 1/3 to 5/8 throttle
The main jet controls the rest

I run totally naked - no air box at all. I have a custom made Uni directly on the air intake. I have a C50, so I just plugged in the PC III. But, I'm trying to get some info for people who want to do the same to a carbed Volusia, and will need to re-jet. Check the thread below for more info, and any help/pointers is greatly appreciated.

Some people think that they know. But, they don't know enough to know that they don't know.

I dropped to a 35 pilot jet from a 37.5. I am closer to sea level but did dial it all in using dyno runs.

If I wanted a Harley I would have bought one....son!

Went completely nekkid last year, used the matrix as a starting point.

2001 Vol. Used a 35 pilot jet and the DJ 150 main jet, DJ needle on 3rd notch as directed in the DJ instructions, mix screw out 3 turns, UNI Filter and depaired, debaffled & demickeyed mufflers. Ran slightly better than stock setup, but would bog down a little at full throttle. Would pull harder when throttle was reduced a bit indicating a bigger main jet was needed. Also suspected the pilot needed to be larger since it would still take a while before I could push the choke in and have it idle at proper rpm. Would also be a pain in the winter time at or just above idle unless I kept the choke out some.

My rides are mostly between 500' - 1500' above sea level.

Almost 2 weeks ago I put in a 40 pilot jet and the DJ 155 main jet, didn't touch the mix screw or needle. It made a nice difference! No more bogging down at full throttle and can push the choke in sooner after start up. This should also allow it to run better in the winter when I take it out for a spin in 30F weather.

Now I will have to watch and see how much it hurts the gas mileage.

Jetting fix

OK r.e. jet sizes- if Mukuni runs about 10 smaller than Dyno for equiv. sizing according to the "matrix", does that mean that a 37.5 Dyno pilot equates t oa 27.5 Mikuni pilot? I run stock pipes, K&N in the airbox, and rejetted to a 140main/35pilot Mikuni sizes, and it still needs 1/3 choke to roll on w/o stumbling. Above 1/2 throttle it pulls well. Vibrates a lot now, too, and backfires a lot. Mechanic also adjusted the fuel pump rather than the shims and raised needle, as it reportedly didn't run well. Could it be that I need a much smaller pilot?

Re: Jetting fix

I could be wrong but I have not seen any pilot jets made by Dyno. I believe all the references to pilot jets are Mikuni's.

If you need the choke that is a key symptom that it is too lean. The choke richens the mixture. Have you adjusted the idle mixture screw after rejet?

Don't know of any fuel pump on a carb Vol so I don't know where the mechanic got that from.

Mechanic said he adjusted the "fuel accelerator pump'', which I had not heard of either... I have not adjusted the screw again after rejetting- that could be it. I did before, (first mod, actaully) but otherwise just told him to set it at 2 3/4 turns. I'll try it and see.
Thanks!
Work sure cuts into riding time when the days turn short....

What Is Pilot Jet Part Number?

I need to order either a 37.5 or 40 pilot jet for my 03 Vol. I have the K&N carb mount filter, and Cobra Drags. Just got the Dynajet 3195 kit, was gonna go with their 155 main recomendation but want to get a pilot jet also.

I can't find the exact pilot jet to order, part number, or where to order.

Can anyone help?

Thanks.
