Any recommendations for carb jetting sources/dealers?
Looking to buy different size jets for:
1.... A 19mm Kei-hin (Have 38 want 40 and have 92 want 95 and 97.5)... 38/92 is Stock for Honda pushrod 90 2... 22mm Mikuni has a #15 pilot, 95 main.. Anybody know where to get larger jets ? Regular Mikuni hex doesn't fit.....Intended for the 125... 3... 20mm Sheng Wey came with 125cc engine, but has 36 pilot and 85 main jets (seems a bit small for a 125.... 4 ...20mm Fentai came with an 86cc Lifan with 33 Pilot and 78 Main (seems WAY small) LOL...Three horizontal (2 clone) engines and none of the carbs are alike or close in jetting..... Anyone willing to post engine cc and carb brand/jetting that's working will be appreciated...... I did find some jets for the Kei-Hin and Sheng at DRATV, but not all the sizes I wanted..... |

You might want to try the following vendors, Steve.

I've visited the Jets R Us site several times, but I ended up buying from Scrappy Dog. I was buying jets for a 50cc scooter, but they also have horizontal engine stuff: http://www.scrappydogscooters.com/70...ORIZONTAL.html
I've also purchased Keihin jets OTC from my local Honda dealer. They keep them in a large plastic organizer, and I just match 'em up. I do the same at the Yamaha dealer for Mikuni jets.

Weld,.... Between the site you gave and one of the ones from Spud, I have managed to find all the jets I think I might need for the "clone" swaps.....
Now the only part I'm still missing is a 10mm high insulator block (manifold to head) with a 20mm bore.... (DRATV is "temp" out).....I'll probably just fab an aluminum block and use one of the thinner insulators and gaskets, but I really need at least 10mm to effect a smooth bore size transition...Longer would be better, but I want the carb to end up in relatively the original positioning so it connects properly to the original intake tube...... Like any other modification, this is simply a series of small changes/steps to work my way to the desired result........  Steve |
