After that $1103.00 debacle for an original pie crust I quit lookin'! I believe at $299 that's cheap for an air scoop tho. Most times they start at $500. Which is still just about nuts ....

I’m back On the Worksman drums ...I can’t let them go....! Cleaned and sanded hubs again . Running modern inverted levers with heavy duty cables will be my final attempt..ya right. I want to ride,!,!
so I found a local welder for my small jobs. Had him weld on 2 wrench flat collars and move pin on front drum to opposite side.
Just repainted forks and installed them along with my 7/8“ handlebars. The wingspans of this setup is 36” . Hoping I will eventually remove shims and go back to my original 1” bars .

It's nice to see the Bull Horn levers back. I have a terrible case of covet.
Really your sick?It's nice to see the Bull Horn levers back. I have a terrible case of covet.
Nice. Glad you stuck with the inverted levers.
Just wondering if those bar clamps are up to the job of coping with the leverage applied to them from the split bars?

Geez ya freaked me out! LolCovet not Covid
Pete ,....don’t freak me out !
So bars are good and I will keep an eye on them . Took her out a few times engine fires on first pull and runs flawlessly! But as we all know this hobby comes Challenges. Mine came to me after the build was complete and my all belt drive slipped. It was time to go chain to belt which is great ...no slipping at all.But to do this I had to fit sprockets in place of pulleys. Which needed to clear the mount and clear custom clutch cover.Thats were my new problem starts.. gearing is all jacked up and my first time with a clutch and engine braking.. wowza!!!
Here is what I got and easiest thing to do would be get a larger tooth clutch.. But is it enough?
10t clutch to
32t sprocket to
3 1/2” pulley to
15” rear sheave
Please leave you 2 cents!

Still marvel at the quality of the build every time I see it.

Engine braking is a wonderful thing as you discovered! Not as much need for disc brakes if your overall ratio is low enough. On my two 5 speed bikes I'd say 80% of my braking is handled with engine compression coupled with down shift. Though the Simplex has dual disc the Harley Peashooter is a coaster rear and Sturmy drum up front. The Harley stops just fine, but pure clutch and stops take a while.
Mags, in post 261 this thread you said the final ratio was 12.25 to 1. Did the performance suit you with that ratio other than the slippage? If so duplicate with the new setup substituting pulley dimensions with gear tooth count to match your old all pulley setup setup or change as suits you. There are ratio calculators on the web as well or you can pm me with the metrics and I'll work up some numbers for you, but I figure what you were running is close to what you will be satisfied with. A great bike deserves a no slip setup for sure.

Thanks guys!
Yes original ratio was good. Soyoy just jogged my brain...I did try to get close to the original ratio as I could with the exception of the clutch. The pulley clutch dia. Is a lot bigger than my 10t clutch. The bigger clutch should help get closer to original setup.

And great joy again was found in Mudville!

And the crowd goes wild!
You might just need more wraparound on the 3.5" pulley. Maybe a longer belt with a tensioner wheel to get at least 50% wrap?
Great tip and reminder Tony of the wrap effect especially on small diameter pulleys and the use of a tensioner to achieve it coupled with a longer belt.

Thats something I was not hip to. Makes sense .I will look into this for sure..thanks .Also I believe my original 12:1 ratio was off. Between slipping and the wrap I had to be off.
Make sure it is on the slack side, or bottom side. Check out manual clutch on lawn tractors...........Curt
Thanks to everybody!!! I’m now headed in the right direction. First learning about belt wrap and my lack of Belt wrap! Added a few. Links to belt which helped.. looking into my tensioner box tomorrow and hoping to find a good location on the bike to mount. The biggest change was the clutch . I moved up to a13t from a 10t.. Brought bike to a nice spot for cruising at low and higher speeds. Next tensioner to help wrap belt . Belt only slips when I jump on it. For now I’m very happy with the ratince again thanks for all the help.
nce again thanks for all the help.
Can you post a pic of your drivetrain side as it was with dual belts for me?
