which manifold is right for a spigot type head with coarse threads

Question by: adam on Apr 21, 2016 9:23:00 PM

The course threads would be the option of "Thread In 1-3/8" x 16 TPI". What year is the head?

Which of these duel carb kits fit a 1979 T140E Bonneville that has two Amal Mk 2 carbs on it now?

Question by: Don Griffith on Dec 28, 2016 10:11:00 PM

MAP does not offer a Mikuni Carb kit for the 1979 model Bonneville. The 1979 model has a parallel port head, which causes the Mikuni carbs to be too close to each other. Some customers have used our MAP0369, MAP0360 AND MAP0364 kits (ordered without our manifolds). They then fabricate a piece of rubber to sit between the carbs to stand them off from each other. Others have trimmed the flashing on the float bowls for the same effect. Another issue is the side covers can't be used with the Mikuni carbs on this model. Another option is using the Amal Mk 1.5 carbs on this bike. We sell those as well on this site.

I have a 67 650 tri. The 32 mikuni carb kit what is the jet size. Are they pretty much bolt and go
Thanks

Question by: Rick jones on Mar 10, 2019 10:32:00 PM

In most applications our kits, for the most part, are bolt on and go. The idle will need to be adjusted and the carbs will have to be synced properly to get the best performance out of them. Please keep in mind that our carb kits are jetted for stock bikes ridden from sea level up to about 3500 feet. Performance modifications like big bore kits, race or street cams or open exhaust, as well as bikes ridden at higher elevations could require some jetting changes.
Our 32mm kit is best for bikes with a performance cam, big bore kit and a more open exhaust. If your bike is mostly stock, I'd go with a 30mm kit.
I've attached a link below for a Mikuni tuning guide. This guide will show you have to sync your carbs and how to test to see if the jetting is correct for your bike.

What size main and air jets are installed when shipped to a customer?

Question by: Ed Balas on Apr 28, 2018 11:50:00 AM

The 30, 32 and 34mm kits come with a 210 main jet installed in the carb. We also include 190, 200, and 220 main jets as well. .

Which kit works best on a 1973 T140 Bonneville with stock bore?

-1

Question by: Richard Hinely on Feb 26, 2020 4:31:00 PM

Which kit you choose really depends on your bike and how you ride. If your bike is close to stock, that is, stock cams, stock bore, stock exhaust or baffled exhaust, then the 30mm kit would be best. If your bike has some mods, like a mild street cam, a tuned exhaust and maybe a big-bore kit, then the 32mm kit will work best. If your bike is a race bike, or a purpose-built street performance bike with race cams, bigger valves, head work, open exhaust and a big bore kit, then you'll definitely want a 36mm carb kit.
A lot also depends on how you ride. The bigger carbs (34 and 36mm) will offer the best top end performance, but will not work as well as the smaller carbs for the general, around town riding most of us do. The 30mm will provide good low-end power, for instance when you are accelerating off the line, or when powering out of turn. This is where the smaller carb excels.
With your setup, I would generally recommend the 30mm carb.

Do you have a carb kit for the 79 750 parallel intake head? T140E.

Question by: greg mackay on Nov 1, 2016 4:43:00 PM

Not at this time, but at some point in the future, we do plan to create a manifold for use on the parallel port heads.

Answer by: Web Support (Admin) on Nov 2, 2016 1:39:00 PM

I bought this same carb kit for my T140E around 1982. I am rebuilding it, again, and would need the intake rubber sleeves and the pancake style air cleaners.
