From crap to the dump? I hope not. So i have ownership of a kymco agility. Got it in Tennessee. When i got it, it was stock. Except for a k&n style pod filter directly attached to the bell of the carb. So i went about ordering a pile of parts... (insert pic of a box - full of bigbore bits, cvt bits, and a glixal 20mm cvk carb & mainjet kit) and went about installing that. Found the silver throat restrictor ring in the intake while i was tearing down the top end. Delete. Put down a 52mm bore, 47mm head, and an a9 cam. Then went about tearing down the cvt. Restrictor boss on the vari. Replaced with a glix vari, 5 gram slider weights, and stock pulley/clutch had all blue springs (i'd find that out later tuning the cvt). Before i dropped in a new glixal replacement clutch, i swapped the factory loaded red springs with blue springs, and a new clutch bell (them cheap versions of performance clutch bells). The old one was heavily overheated, blued beyond belief. Again, when i remember how to put pictures up... Buttoned er all back up, gave the new carb an 85 mainjet, and... took foreeeever to try to get it to start. I figured a 32 slowjet was fine (thats whats also in the oem carb), but it was dumping so much gas trying to start. Open close open close, adjust adjust adjust. Kept trying to get it tuned in, and in my frustration, i accidentally clamped a bit off of my only bowl gasket. So i borrowed the schwinn's carb setup, and got it to putter... start... slow ride. Very slow ride. Definitely regressed. Effit, i need the schwinn. Put its carb back. Popped open the kymco carb. Mainjet is a different size thread than the cvk i ordered. I took 5, and then started comparing the kymco carb and the glix cvk, and thats when i realized those 20 dollar carbs are garbage. 20mm out the throat, but thats a sham. They only machined out a 20mm step. Anyway, i got a spare with a bad gasket and a bad step-job that i can eventually jack around with. So i put the kymco carb - as it was - back in there. It took a bit to get it running the first time. But once it started, it ran. Guess it'll do for now. So i gave it a half mile shakedown and trans was waaaaay out of tune. More tuning, adjusting, playing, etc. Headaches. Ended up with the 6.5g rollers i had, glix vari (and boss), and stock setup clutch/pulley, performance bell. In amonsgt all that cvt tuning, i realized the contra was too heavy, and the clutch was engaging near top rpm. And thats when i realized i didnt have any stock springs. I have 2 sets of blues and a set of reds... and theres no power in the top end. But it rides like it did stock.
As i got to riding it around, it has a hard pull. I need to keep 5-10 extra pounds of pull on the left handgrip to stay square in the road, handlebars wanna fall over to the left just pushing the bike 5 feet across the shop floor. Some more examining, it looks like the bike, some time before my ownership, suffered a dump or loading/unloading accident... or some kids bein idiots... but the front end's tweaked. I've been discussing this in a general thread, i just have to make time for it.
And it survived a move back to minnesota. I got more parts here. I keep finding more as i'm sorting and sifting my workspace. Ordered a new big valve 52mm head, gonna examine the squish in the cylinder before and after. I think i remember as i was mocking up the big bore, the piston didnt even come close to flush with the cylinder. Estimate of 4-5mm below the deck? I wrote it off to the gasket needing seating, and gave the whole setup a torque. I likely assumed the torquing took up a majority of that space, but since riding the gutless wonder, i aint so sure. Anyway, its in pieces in my garage. I gotta find more of my bits n shyt. The ones i need, specifically. And rerun the fuel line with a brass shutoff. Does anyone know the thread size of the fueltank mounted vacuum petcock and where to find a threaded brass hosebarb to replace it? Bonus if it has a 90 degree elbow
