As in those cheesey bumper stickers. I love that 6 speed. I put it in back in '0, not many people were running them, so it was kind of a novelty. But I'm a true believer in the utility now. I'll never run anything else. Rode a buddy's Softail with 5 speed. I really wanted to shift again.

From my experience (not with the Mikuni) RPM is the biggest killer of gas mileage. When runnin' the freeways, the closer I get to 4000 RPM, the lower my MPG (30ish) Stay around 3000 RPM and the mileage stays closer to 45-50 MPG...
Buddy at work rides an 06 (EFI) Ultra-Glide and got the same results...

The relevant post:
"That was with an SE/Mikuni HSR42,I had it tweaked just a bit more and got that lag out of it and it ran great but I could never get decent gas mileage out of it and have since replaced it with an SE/CV 44.
Power is almost the same,throttle responce isn't quite as crisp but it's still quite good and I'm getting about 36mpg on average with low at about 32 and high at about 39.
Not bad for an 800lb carburated bike with over 100hp and that's riding two up."
Hope that helps.
I talked to the guys over at Fox Distributors and they sell a kit for the Mikuni which they call the Mileage Kit. This removes the lag and increases the gas mileage.
They sell these kits to Mikuni since Mikuni doesnt manufacture it themselves. The kits only 40.00 but from what I heard from others running the kit in their 42mm the kits does drastically improve the lag and they get better gas mileage.

Sweeet. I just got off the phone with a guy from Fox Distributors in ILL and they deal with Mikuni all the time and he told me that HD can blow it out their ass. The newer carbs after 98 dont require anything i.e. cables unless i change my handle bars.
Everyone except HD has told me that with my exhaust, cam, and changing out the carb that bike of mine will experience a tremendous difference in performance. I have also looked at changing the ignition system as well to get a little more pep. Well see.

| Yea, I should have said that also because that is what I had bought along with the hypercharger (which I no longer hae on). It is an easy bolt on application.

| I know that Mikuni sells an easy kit 42 mil that just bolts on using all stock cables and breather etc.

Sorry to jump in but I have an HSR 42 on my '01 FLSTS. No new cables were needed either with my stock bars and then with my Chubby W0510's.
I did have to get longer cables when I put the Chubby W0531s which had a 4' rise and a 2'inch pullback, but that does not seem to be the case here.

I used to have a 100" w/ a Mik42, and a friend of mine ran a Mik45 on a hopped up 95" motor with great results (109hp, 105tq)
EDIT: Oops, forgot to arrive at that thing that people like to call "a point" - I think a 42 will work just fine on an 88.
re: cables - I'd try it first. I had people tell me the same thing, and the same cables that worked on my HSR42 worked on a CV, and now an S&S G (3 diff motors) So I dunno

Thanks guys for the infos.
The stock cam was pulled just before I bought it and a aftermarket was put in at the HD dealer. The paperwork states aftermarket higher rated cam installed but no lobe info or sizing so that just doesnt help. But I figured that since the cam has been changed and it runs pretty well I might as well try and make it run great by changing out the carb.
I talked to the dealership and they told me that the Mukuni is a stright forward installation however if the carb wasnt bought through HD then additional replacement cables would be needed.
The card came from Drag specialities so I am imagining I am gonna have to buy some cabling. I am gonna wait until the riding season is over in MN and then do the change over in the event i run into problems and have to wait on parts or what have you .
HD told me that Yes since my cam is after market and I am running a aftermarket hi pro exhaust then the carb swap would be of great benefit. they said to fully maximize the system the cv would have to be tweaked a little and not really worth the time and money and that changing it to a mukuni would benefit the performance better.
well see i guess.

I agree with Weasle.. My '99 twin cam Dyna runs perfect with the CV carb.. Although it has had a Screamin Eagle breather, K&N filter, and jet change added. If your after hp probably won't gain much with the Mikunni's- not sure on that.. and your gas mileage will probably suffer... Interesting though...

Not knowin' anymore than I do, I'd be thinkin' the same as you. Carb on the bike, no computer to deal with...
Should basically be a bolt on affair. Manifold (and cables) would be the only issues, unless you got that with the carb. But, we could both be wrong...

I have a 01 Dyna Lowrider. From what I am reading it is just the HD stock CV carb on it. I am wanting to get away from the CV and put on a Mukuni 42. I have the brand new Mukuni already.
I talked to one guy today and he was telling me that it is extremely difficult to change it out and tune it in on the Twin Cam bikes.
He told me I would need to get it hooked up to the computer so that the chip could be read blah blah blah.
To my knowledge my bike is a carberated bike, why would I have to have the chip read and have it tuned from the chip . I thought that only applied to the newer twin cams with EFI's
I knew that I would have to have the carb set up properly . Basically what I am asking is what do I actually have to go through to get this CV off my bike and get the Mukuni on it?
Thanks a million for the help guys
