Agility 50 / Re: 72cc BBK and 120 Jet Popping

« on: July 07, 2013, 07:35:47 PM »

Im running a 72cc kit with stock exhaust and open foam filter. Ive got a 92 jet in it now, anything bigger causes popping at half to full throttle. One trick I did to dial it in was, start with a jet thats a little smaller than 120, maybe a 110, cut a 24oz beer can in half (bud light cans work the best), slip the half of the can with the open tab over the air filter and go ride it. If it pops worse, than you know your to rich. I started with a 98 jet and a can over the filter, and now im down to a 92 with no can. What plug/coil are you using?

Hey guys, its been a while since I've posted on here, but scooter season is almost here and its time to fire it up. I installed a 72cc kit last fall, and only got to ride it a couple of times. I was wondering what main jets are you guys using, and with what other mods? I've got a 90 jet in it now with a polini variator/6.5gr sliders, 2000k springs, open foam filter and stock head, cam, and exhaust (muffler has extra holes drilled in the end from the previous owner).

Jaws, do tell what you're using as a flasher relay and how its wired when you get it. I used an eflr-1 flasher relay on my r6 taillight on my ruckus. I got an idea for my agility to do away with the stock flashers.

Still using the stock kymco flasher for now. It does have a fast flash, but I've got some load resistors that I need to wire in to rear lights

Ugh, this tuning thing is ever ongoing. I got a metric drill bit kit that ranges from. 3mm to 1.6mm. I started out with a .85 and the plug looked lean, same with the .90mm. So I stepped it up to a 1.0 or 100 jet, and it now pops like it way rich, but the plug doesnt look overly rich. My problem is my buddy, he's raced 4 wheelers since a kid, and keeps saying he knows what the plug should look like when its running correct. He said the electrode ground strap should not have any white on the tip, he says that's lean. I thought I should be looking at the white insulator around the electrode, and tune the carb till it has a chocolate brown color. I just want to make sure im doing this correct, should I tell him his way is wrong? Sorry for the long post, I think I should just put a .95 jet in it and check the plug after a few minutes of riding.

I started with an 85 jet, but doing plug checks, the tip was white. I have been slightly reaming the jet using some very small drill bits, but its not exact. The jets in my cvk carb have a tiny thread size, like almost 3mm. Im looking for a tuning jet kit to make my life a little easier. I was I had the bigger thread jet, I work right next to a honda motorcycle shop and they have all the jets in the bigger thread size.

Hey guys, trying to tune in my 80cc bbk. I need to find a jet kit that has 100-112. Anyone know of a online shop ( not in asia ) that sells them? I've checked ebay, but the kits don't have the sizes I need. Thanks in advance!j

Thanks for the kind words! I was thinking of welding in a top tube for extra support, kind of like a motorcycle. Then in the future, I could mount a fuel tank on the top tube. Id have to make a cross brace to mount it on the bottom, not to big of a deal

Hey guys, thought id share a pic of my 08 agility 50. Still a work in progress, but its been chopped and lengthened 10 inches using 120 wall pipe (really thick), custom handle bars and using the flip up backrest as the new seat. Also in the works is an 80cc big bore kit. Hope you guys like it. Ill post more pics when I get it done

They are 64mm in the GY6 50cc's. Just one or two brands use 69mm

Awesome! Thanks zombie
