which carb do you recommend?

[NHBagger]

I ran a mikuni 42 on my 107" and it was flawless. I did switch to a 45mm trying to chase a few extra ponies. Set of the pants no difference but the dyno showed 6hp increase. Same dyno.

Do you remember if the torque changed?

How much hp was you able to pull out of the 42 mik?

[05fatboy95]

The tq went up 2tq but I figured that could be just the dyno. I had 109hp 126tq before and 115hp/128tq after sae. If my memory serves me right.

In all fairness the first dyno day with the 42 the build was new. Just some heat cycles. I put the 45 on about 2k miles later. I got the 45mm on eBay for $100 and did a rebuild kit. If it wouldn't have been that cheap I wouldn't have done it as the 42mm worked great. Dyno guy did another run, idk what he did (different gear or timing) but it got 119/131 sae on the 42mm but it was just to kinda show me how people can inflate the numbers if some one wanted.

I'm a fan of the CV. Have had great results with them on 3 bikes, from mild to semi-wild, along with a 4-pack of 'em on my old Kawi ZRX1200R.

Planning on taking my '02 to either 95" or 98" next year, with cam & heads with an emphasis on torque & debating whether a CV44, or Woods 40.5 or 43 would be my best bet.

I had a good conversation with bobby about his carbs..they have good reviews, and evidently do what he claims..but you better get your checkbook out, cause they aint cheap

On this comment, I would disagree.  I've had my Mikuni HSR42 from -200 ft (Death Valley) to 14,110 ft (Pikes Peak) and have never had to adjust the carburetor, it runs flawlessly.  It was perfectly tuned at 1000 ft with a a/f meter.  And!!, I get 44-50+ MPG.  I would put the Mikuni against any other carb, any day.  The Mikuni is the best steet carb, it doesn't feel like a mush bucket when you twist the throttle.

I had a 48mm mikuni and it was like fuel injection.  I liked it very much, but it was too small or id still be using it.

on the hsr45 and 48..will a se backing plate work, or do you have to use the mikuni air breather setup? I was looking at the hsr45 kits, but cant find anything on whether stage 1 and 2 air breathers work with them

I am not sure, never seen an SE plate.  I had a mukini mount that I used.

Got a Rebel 43.5 on my 95" Heritage.  Like it a lot.  I own but have never yet run a Mikuni.  Like the Rebel too much to mess with it...

There is an adapter you can buy to use the SE plate or heavy breather set up.

I remember those.
A friend of mine had one in a box with the Bendix and Holley garbage carbs.
Might be worth some coin later on in a museum.

There is an adapter ring that can be fitter to the Mik so you can use the SE backing plate if that's what you are referring to.

A properly prepped American made S&S G will smoke a Rice Mikuni (been there, done that/seen that), but a Mikuni is a great all street carb if you can ignore the slide rattle noise...Have no idea what a CV will do and Woods makes a real nice carb but his "King" carb is a King with out a crown-there is only one King and it holds more world records that all other manufacturers combined-

Hey PW, long time no see.
To be honest, the guy wants an upgrade for the street, not drag racing.
Can't see an S&S out doing a Mik on the street at all.
What have you been up to.

Is that with or without thunderjets ?

[jrgreene1968]

I've considered trying a g..but everything I've read says they suck for gas mileage

How's it going?
Just screwing around-street and local tracks.
Yeah re read my post.....as I said a Mik makes a great street carb, some are annoyed by the slide rattle.
A G can be set up to be a nice street carb.
Running them seven years now on the street-works for me-
No drama but you have to know what you are doing....

I have one of these adapters on my 113. I used to run a heavy breather but switched to the SE backing plate with zippers filter. Now I'm switching to a Doherty  backing plate with the zippers filter. The hole in those adapters is sized well for a mik42. It is to small for a mik45 or mik48. If you run one you'll want to spend some ttime with a dremel and open it up.

True, it you want something enough you'll find a way to make it work.
I'm still running Miks and have no issues with em.
Never got the chance to play with a Guppy pipe though.
RB is easier to get a hold of.
I'm sketching up a new primary casing to be able to deal with a compensator / tensioner I have ideas on.
