How i got over the carb finishing close to the chaincase side was get from the scrapyard a length of radiator hose that had a kink or slight curve in it. My Dellorto is the 25mm rubber mounted type. The kink moved the carb away from the trouble areas. I might use the same piece when i finally get my reed block fitted Embarassed

Vega 140 carb and reed block

Post  tonyicon on Sat Apr 20, 2013 8:09 am

I have spent some more time futzing with the carb fitting, no elegant solution has occurred to me yet. I got a ScootRS Atomic reed block to try and although it relocates the carb a little, still not enough to fix the problem. The Atomic reed block itself needs fettling to fit the StarStream barrel, but not much. My impression is that it is a better quality job than the LTH unit.

Trotsky's installation with the Dell'Orto is much neater.
Here are a few pics of what I'm on about.

Also the rubber mounting flange for the 26mm Mikuni is not a terribly good fit (no annular ridge to mate with the bump on the carb stub) I fear it may 'wiggle off' all too easily in use.

Any thoughts etc would be welcome!

Carb Fettling

Post  trotsky on Sat Apr 20, 2013 2:00 pm

Hi Tony, did you get the Mini Atomic? Very little fettling is needed on my Starstrem Barrel. I've started my Dry build & below are some Pix of the Carb set-up, hope these help. I trimmed the Cowling & mudguard to fit & we had a spacer made to clear the carb from the crank-case (may be able to get some made if any-one wants one). As you can see the Carb misses the Kick-start by a good margin so there'll be no issues with a Filter.
I stole your idea & got a Sunny rear hub as well Embarassed & i'm gonna use a Zip type front wheel so i'll hopefully be Tubeless all the way cheers The pix aren't that good on here. so if you PM me your e-mail addy, i'll send some over that you can enlarge to get a good look at. Will post more as i go....Cheers Steve

Kickstart

Post  tonyicon on Sun Apr 21, 2013 10:24 am

Hi Joey
Can we see a pic of your modified k/s lever? I was considering trying to make a folding lever as used on many vintage motorcycles, but I am not sure that would work within the space available

Cable Routing

Post  trotsky on Sun Apr 21, 2013 1:31 pm

Here are some Pix of my cable routing with the Atomic Reed Block. I do have a 6mm barrel packer, so i have a little more space for routing. Tonyicon cleverly used a Carb elbow to get around the tight Reedblock/Gearblock space....Cheers Steve
