For those of y'all that are running Mikuni's with exhaust and heads, How do y'all have them set up?

Like i said, I've got heads and exhaust and Im about to put a Mikuni on my motor.

So what main jet are yall running? What about the pilot jet? What do yall have the jet needle set at?

165 main
standard pilot
jet needle clip was set up one from middle setting

Thanks Gary.

Anyone else?

Same as what Gary said. During the cold months I like to put a 30 in for the pilot.

Mitschke please document and take pics of what you do. How are you adapting the Mikuni to the engine?

Just to make sure that were on the same page. What size is the standard pilot?

Marcus, i gotcha covered.

25

My mods

BPS HSR 42mm Mukuni Carb kit

EVT heads decked .055

EVT HO/loud exhaust


Running

Main Jet: 162.5 ( Tried the 165 it was to rich )

Std. pilot jet (25) ( but I plan on upping it to a 27.5, motor hesitates a little after warm up)

Pilot air screw ( idle mixture) set at 2-1/4 turns

Std. needle jet (97) set 1 notch down from center.

Std. accel. pump nozzle (70)

Preston is on top of this!

Raise it back up a notch and try a 22.5 pilot. Every vert. we have done liked the 22.5 pilot. Cold weather may require a 25.

170 main
25 pilot
3rd notch down on size 97 needle

I'm running a 25 pilot jet at 1 1/4 turns and still running rich.

I think I see a ghost

BOO !!!!

.065 decked heads, evt intake, evt exhaust, Mikuni HSR 42

165 main, 22.5 pilot w/mixture screw 1.25 turns off bottom, one notch below center on standard needle... sucks a fat one coming off idle though, always has. can't just mash it & go... gotta use kind & gentle words and once you got it convinced you'll play nice it'll start to go then you can beat it up.

yes I have & have plans to try it out..... but can't ever find da time not to mention I'm sick of wrenchin on dis mofo.

I'll give a free sack of crawfish to whoever can fix it......













later on when they ain't payin us $125/sack no more

swappin da intake isnt that hard.. But I hear ya about wrenching on crap. I got a Toyota truck that needs a front end rebuild AGAIN. I dont want to do it.

I know der ain't shit to it, but der also lies an uncertainty that it don't run worth shit an I have to swap it back. Still ain't a big deal, but after countless case gaskets, cracked blocks, cracked sumps, blown engines, etc.... For once this mofo is running without any real problems to speak of and it's crawfish season so I ain't touching it if I ain't got to. Just sick of wrenchin on shit, that's all.

no... tried every clip position on the needle that's in there with no improvements though

Mitschke, Mukuni makes a great carb, Your going to like it myboy.


My only dislike is the cable bracket and the white nylon sheave causing cable strands to break.

Someone needs to come up with a better design and do away with all that unnecessary linkage crap and reroute it point A= cable to point B= throttle arm 1/4 sheave. hint, hint.

Someone needs to return pm's.... Hint.... Hint....

Lol

I've been trying to come up with a design I like but I really just haven't have time to make one. Just like the reverse thing.

I am not a patient as you and I don't wanna make all of that shit by hand. Then I don't wanna mess with tooling in a cnc, because I Would have to use personal stuff here at school. But, if I went home I would have full run at my neighbors shop and I wouldn't have to buy tooling.

The more you hound me, the more i wanna finish something lol
