Not heard about any of those being fitted. The performance/quality angle is amply covered by the Keihin 39mm FCR, complete kits available for easy fitting to bonnies:

42mm Mikunis. Amals? Delortos? nope.

 

Thanks for the advice and help guys. Currently evaluating Lectron power jet carbs.

 

See this thread for some advice on Lectron carbs:

Rich,

Not sure I feel all that easy with the "poorman's" reference, but I know what you're saying. "Budget-minded" sounds less degrading.

Mega,

The Keihin kits are OEM factory manufactured to be a direct bolt-on for the 790 & 865 twins. Take note: Some shops play around with the spigot length so as to make them compatible with other parts they sell.

Amals, Lectrons, Mikuni's, are all set-up for individual throttle cable(s) per carb. So if you want to retain the original push-pull cable set-up, you now need to split 2 cables into four.

I got a twist grip off a Vrod for my Mikunis. Worked fine

 

Vitessi,

I guess any 1" throttle assemble could be made to work. But here again, being -ahem- 'budget-minded', replacing the throttle assembly would suggest also having to swap-out the switchgear and possibly clutch lever assembly so everything matches. The CR-II and FCR's (as supplied from the factory) bolt right on in minutes and retains the stock cables and manifolds. I'm curious how you set-up your controls.

Rich,

I always joke with my customers that "I offer Price, Quality & Service. Pick any two." Most customers get the joke. Most....

/M

 

Everything came with the kit, no switch gear needed changing, it was plug and play after the needles were set.

 

Thanks guys, but my mate. who owns the bike, has this mad wish to not have jap carbs on his bike!!! Lectrons seem the best bet.

 

Hmmmm....well don't tell him where the brakes or front forks are sourced. I'm sure he can get some old meridan forks to work in some custom triple trees!!

Good luck with your endeavor.

Regards,

This gentleman has detailed his experiences with the Mikuni carbs:

http://triumphbonneville.org/mikuni-carbs-for-the-2008-bonneville/

 

Although there is an individual on this forum who has nothing good to say about Gately and Bonneville Performance, he is a friend. He and I installed the 42mm kit in an afternoon. From the get go the bike ran, idled and delivered incredible torque for just a carb kit.
The best most satisfactory thing to do is forget about "budget" anything. Save money get the best, the entire kit whichever you choose. Take your time to set it up properly and it will be your last set of carbs you will buy. DON'T CHEAP OUT.

 

< not gatleys friend but the 42 kit works ok it uses a hd throttle and cables the 2 carbs are hooked together on one shaft you move the right hand controls over alittle and slide a after market hd throttle on with push pull custom made cables.
I have both them and the fcrs .The fcr carbs are the best the throttle even feels better (quicker).fcr is way more tuneable also .But if you have the 42s you wouldn't know how much better the fcrs are the 42s are way better then stock.The 42 and the fcr make about the same top end hp but the fcr has way better low end and mid range.

 

I am not a carb guru, nor a tuning expert. I've got a solid background in fitting Mikunis in place of Amals, and Dellortos in place of Bings. I recently replaced my stock CV units with CRs and could not be happier. I struggled with the FCR vs CR question for a long time. Most people are solid FCR advocates and poop on the CRs. I have a 790cc T-100 with no intention of going 904cc BB kit, and no substantial head work. I felt the FCR was overkill for my application, where as the CRs were better and cheaper. I may put an 865 set of jugs and some wiseco pistons someday but even that would not justify the FCRs at a thousand bucks.
I agree, that the FCRS has more potential for growth and huge numbers. I fitted the CRs to a slightly modded Bonnie (exhaust, pods, igniter) it immediately began to slip the clutch and rip through the gears so fast it was stupid. I put green springs and upped my stock 17t for an 18t and after a bit of jetting and tuning (super easy with the CRs) I am happy with all performance and highly recommend the CR if your end goal is the most streetable, stock bore hot rod Bonneville that instantly reminds you of the best running Norton Combat Commando your selective, biased, rose tinted brain can muster, then Hell yeah.
Are there guys going faster with 904 kits and FCRs?? You bet. I doubt there are 790 or even 865 Bonnies with FCRs that have anything on me.
FCRs...yeah
CRs...yeah
Mikuni...yeah
Anything better than CV...Hell Yeah

Sorry, I just saw where the goal was to be rid of "Jap Crap" ....ha ha ha yeah man, I'm with the program. I'm gonna ditch my CRs for a nice set of Amal Concentrics and trade those nissin brakes for a true Lockeed caliper. I might even swap my Lexus for a MG midget.
I thought performance was the target, my bad. It's a big world and there is room for everyone, so right on and good luck.

 

Not my choice mate, I know which carbs I'd go for or stick with.

 

No worries, I apologize for the long rant. When I realized the requested change was based on emotion, I should have deleted the whole post rather than attempt humor.

Love your bike and build what you want. The older I get, the less other people's choices bother me.

Good luck

Do the R& D for a Amal smoothbore race set up. You might capture the purist market niche.
