Re: Single 34mm flatlside carb kit
Interesting! wish i hadn't sold my old one on ebay for penny's years ago - haven't seen one since, though i imagine the difference would translate to a modest increase in a stock engine
i think we see on this thread (like many others) the difference between "claimed" and actual bhp - :shock:
not surprising - Ok hobot please but in one of your claims now! :mrgreen:

Re: Single 34mm flatlside carb kit
Pick on me all ya like, its one of the most pleasing things of this hobby to wipe strangers smart smirks off, to point I set myself up for it. Now the little details and differences in Miki Carb's coming out will have to check the MIki I put out to pasture with Peel. I get lower 50's mpg on my factory 19T Combat dual Amals at 60-70. On Peel with 21T-ish and 34 Miki, got into high 50's mph at 70-80 cruise. Wiping smirks off dropped mileage to lower 30's mpg and have used up over 2 gallons in 45 min of smirk wiping. Peel is an abnormality to me and everyone, I know what I did but don't know why or what key factors woke her up so much.
With Combat thin stems CHO head, 2-1 mega and daul Amals with flow slots in them, I had to tuck tail behind legs as lost even sprints against ordinary good running Commando's in Ohio. If I've known of these flat slides ready to go a decade ago I'd of jumped on it. I have two Lectrons flat slides I'd planned to adapt but wasted money now compared to JS's and other options. The single biggest power downer on Peel was switching out the break in only 34 Miki for dual 32 Amals with race tapper needles, flow slots and trimmed and matched spray tubes, which are on plain jane Trixie now, with anodized slides.

Re: Single 34mm flatlside carb kit
I would suspect that what Hobot is feeling is torque. It is a wonderful thing that Commandos have lots of. Single carb conversions do not hurt the peak torque of a Commando very much- if at all and that is why people like them. Horsepower on the other hand is developed through RPM and that is were the single carb fails.
There are lots of bikes around that produce more horsepower than a Commando but they may not feel as fast because they have less torque. A top speed run with correct gearing will demonstrate the advantages of horsepower- but what good is that on the street. Torque is king in my book. Jim

Re: Single 34mm flatlside carb kit
Did you have to remove your backing plate? Did the cable clear the frame backbone or did you have to twist the carb a little?
I only did the fuel flow test once and all that matters is that you don't starve for fuel. I haven't tested extended WOT through all the gears. I don't know if your Mikuni cable would fit. The price is at jsmotorsport.com and it includes everything - manifold, twist grip, cable, air cleaner etc. If you just want the carb contact me at:

Re: Single 34mm flatlside carb kit
Last time I weighed Ms Peel during her hi Torque surprise era '04-'05 was 365 lb before I removed 9 lb of LH exhaust and 4-5 lb with rear sets, couple lb chain guard and 1.5 lb with 520 conversion. Never added up before so 9 + 4.5 + 1.5 = 15 so 365 - 15 = 350 lb. *which includes 3-4 gallons of gas in the IS tank because this stuff ain't just academic to me. Gasoline = ~6.5 lb/gal, so 3 gal = 19.5 lb, so 350 - 19 lb = 331 lb.
Ugh damn ADDH, forgot to subtract the chain spin mass, so being a bit conservative Ms Peel was just under 330 lb with oil and filter on empty IS tank. Duh, this includes the luggage rack on with side struts [~ 8 lb] of course as Ms Peel had to earn her keep lugging beer and 50 lb sacks of feed slung over seat, any time my S.O. sent me off on my mistress. Believe you me it was like wild road orgasm sex acts with a light trim ballerina, like, well THE "Mrs." Emma Peel icon. As you can see Ms Peel still has lots to peel off for next time out.

Re: Single 34mm flatlside carb kit
Duh HP is Only Rpm related to calculate. Peel's 34 Miki on 21T-ish gearing in 4th only pulled to 6000, ugh if held on long enough before end of 'straights'. I grantee there was No rpm limit in lower gears just more pull no let off to warn off blowing right up it not watching the fast rising tach. 3rd ran out of good after 110. As long as speeds below 90 Peel could put down more power, snicking 3rd was end of her torque dominance so had to barge into turns rather hotter than the hi power bikes or loose ground in the spaces between turns. Basically i discovered Torque pull rules in the twisties but hp rules the top speed play level. Only quality I liked better with dual Amals was on THE Gravel as took less time/wrist motion to chirp tire to steer, I had to predict more ahead of time on the 34 Miki response to hit below 4000 rpm. Above 4000 or so I like my Miki significantly better. One it a row eh. Broke cog teeth and twisted shafts and blew out a shell in first 3-4 months learning what she'd do. 40 hp tehehe.
Personally I think there good advantage of too big carb on too of small ports if there's a funneling down velocity boost and trip lips with some throttle snap sense if not a pumper.
I'd be saving up for Jim's 'puterize ignition and injector but not sure if can adapt to Peel full scope with and w/o boost. It'd be a natural for a simple land speed tune up though.

Re: Single 34mm flatlside carb kit
thanks Jim. I always thought (seat of the pants) that Sonny"s set up was pretty good. No direct testing, just hard running with souped-up Bonnys and tricked-out Harleys. Their smirks (hobot) didn't last too long when they were told they were shamed by a stock (straight-thru Interstate pipes, 750 headers) MK111 with a single carb. I was thinking of going with a MAP manifold for the project bike, but you just changed my mind

Re: Single 34mm flatlside carb kit
yes, to both ludwig and your comment Jim
that why if you want to make your bike faster, you can try eating a few more salads and hit the gym - benefits are long reaching, kinda silly when i see guys trying to squeeze a few more Hp outta a bike and they them self are pushing 2x the ton plus - with gas tank acting as a stomach stopper :roll:

Actually weight probably rules. I would like to see a Norton that would outrun my stock 300 KTM from 0 to 100. Other than TC of course.Jim

Sooooo, I'll need to keep myself in check or else I'll be -----one of those guys. Cj

For me, torque is it. It make me feel lighter than I am. I have gone a ton+ twice now on this 40+ year old bike with this 58+ year old 225+ pound frame, 105 just last Sunday in third to redline. It's there for the taking, along with my life. I'll take the torque and that's why I take a Norton.
Now, would someone come up with some pics and where abouts of the Sonny Angel Manifold please, other than Moto Guzzi application?

Re: Single 34mm flatlside carb kit
Sonny Angel manifolds have not been available for many years. Once in a while you will see one on e-bay. I think I still have one somewhere in a box.
There is another manifold that is the same as the Sonny Angel manifold but I have no idea who made it. I have one of those also- somewhere. It mounts with only two bolts but lacks the SA cast into the top.
Either manifold mounts the carb a little higher and a little closer to the head. They make for difficulty in cable routing with a VM carb. Jim

Re: Single 34mm flatlside carb kit
I spoke with Sonny while in California back in Feb and told him about the bike I was building and he asked if I was going to need a manifold. I replied that I wasn't sure yet as to how I was going to set up the bike and I would let him know. He said he would send me one if I wanted, so I assume he still has some. He is old and failing fast since his wife died, but his brother Don (who pilots the Vincent streamliner at Bonneville) is pretty much in charge of the day to day operations at the shop. So I think if anyone should contact the shop they should ask to speak to Don. I am not a computer whiz but I will try to take some pictures of the existing set up on my Interstate, then post them. As Jim and I both said, it is a very tight fit. I have found the best cable set up to be one from Rocky Point where there is a 90 degree adjuster at the top of the carb, so the cable doesn't kink at the frame gusset.

Re: Single 34mm flatlside carb kit
Maybe arrange a group buy for the benefit the cause and to possibly lend moral support to Sonny? Let him know there are many people that appreciate him. His manifolds would be a part of his legacy to the marque. Just a thought. Pretty sure there would be some people around these parts to lend a hand.
