Have a 150cc Chinese Ruckus clone. I want to add exhaust and a high flow filter, but don't want to run too lean and cause any damage. What do I need to do about changing jets in my carb? Thanks in advance

If it's a GY6 150 the stock jet is usually 104. Put an exhaust and filter on I'd go 115 for starters. Jets are cheap, buy a bunch both sides of your starting test jet. Then run the bike for a bit and check the plug....black and oily is rich, bare and dry is lean. Alley is the man on dialing in your mixture. I'll see if I can wake the old fart up. Alley! RIBS!! I knew that would do it!! Rich

You got it BRO, 112-115 will do the trick, it all also depends on how much compression the motor is making if really high it will take a 115 if not so high a 112.

It's good to see so many old crusties...er uhm I mean knowledgeable middle aged gentleman, with so much scooter experience. On a serious note, I really appreciate it. Is a 34mm carb going to be too much with the right jets, or should i stick with the factory 30mm?

And you do not need a bigger carb many make that mistake and then have a heck of a time trying to tune it, to much for a stock 150. Alleyoop |

So am I looking for main jets or idle jets when I add the filter and exhaust? I am assuming a #112-#115 MAIN jet correct? Thanks!

Oh and while we are on carbs...Does anyone know what the outer diameter of the intake side of a stock 24mm carb is? Trying to order an intake/filter and don't have a scoot here to measure yet.

You have been very helpful so far. Thank goodness for people like you. Apparently due to forklift problems, my scooter hasn't left the Georgia warehouse. But, I am hoping shipping will be quick since I am in North Carolina. |
