2008 kymco agility 50 Hard time running

[scooterman11]

Hey Guys
the other day I put my after market leo vince pipe on my agility, then I had my jets drilled out to proper size
just yesterday it started acting up and would not stay running its really starting to make me mad
what do I do

[streido]

What size did you drill out the jet to?

Did you secure the manifold down tight so it doesnt leak? Check its not too tight, i did this once and split the rubber underneath causing an air leak. Scoot ran like crap till i found it.

I went down to my local scooter shop which is Lifecycle in kalamazoo and they drill the main out I believe 3 and the pilot 5 i could have what they did mixed up

Those numbers mean nothing to me

3 what? 3mm? Should be 82main on a derestricted Agility, not sure if fitting a leo vince req a larger jet on a 4t ? If it was running good before hand then i would guess it down to the jetting being wrong?

Its best to just get new jets to the size you need. the pilet jet you dont need to touch.
just the main to a 82 any bigger you well get shoked out. and for the muffler if it dont fit tight you may need the washer that goes in there or spacer.

..you will need somewhere in the vicinity of a 95 main jet....


..that translates to .95mm

..the 3 and 5 makes no sense...

..aannnd, the thing is, a pipe doesn't greatly increase 4t performance...oem exhaust can handle the addition of a free-flow filter, which will indeed increase performance, with a few other mods....

wow 95 jet why even put one in lol......

[wordslinger]

..you're right, blue...why even??..

..just put the oem exhaust back on, and slap on an air filter!!

..don't waste tyme with th' dumb sh**!!

Definitely sounds like jetting issue, if they drilled out to 3mm or 4mm, you could just use a funnel instead... I have mine jetted at 1.05mm right now and its waay to rich.

I've looked around for a while to find bits and that can accurately drill jets but they are hard to find. Luckily my neighbor owns a company that manufactures machines specializing in exactly that, drilling super tiny and precise holes in things using electric current. Like in a tomahawk cruise missile turbine lol... he's the most badass mechanical engineer I know.

..any machining hook-up issa good one...

I only have a 80 jet in mine. and it does fine. ( dont touch whats not broken.)

That's where i become confused..
I'm at 2225ft. I should use a SMALLER jet than ANYBODY.. ......I mean TECHNICALLY, with the denser air altitude,etc....

[wordslinger]

..batman, arent you inna historically "dry" area tho???

..i think i'm like at 700' elevation here....

[zombie]

It's an historically dry "county". The Air is fine. There is something in the water tho...
