PostPosted: Sun May 19, 2013 8:55 pm 
2007 Metropolitan. Bought about a month ago with ~1100 miles on it.

Things I've done since I got it:

Removed the intake restrictor/atomizer
Up-jetted the main jet to 78.
Replaced spark plug.
Replaced air filter (then removed it entirely lol)

Things on the to-do list:

Replace fuel filter. (ordered 5/13/13)
NR Magic variator & Kitaco belt (ordered 5/15/13)
Replace warped clutch bell (ordered 5/13/13)
Install Shinko whitewall tires (ordered 5/16/13)
Remove air box/plug PAIR valve/MNNTHBX intake mod
Re-tune carb (test 82, 85, 88 main jets, 38 slow jet probably)
Exhaust?

Not that anybody cares, because I won't have any pretty pictures to put up, but I've made some headway getting this thing running relatively well.

I deleted the airbox, plugged the PAIR valve, put a radiator hose and KN filter on the carb, as well as breather filters on the PCV valve and diaphram port. MNNTHBX's little filter mount thingy is pretty clutch.

Picked up an exhaust header from BrandonRyan and a PrimeLine muffler. It sounds awesome, but coupled with the intake mods listed above, it left me with a real project tuning the carb.

When I started with her, she'd only lug my fat ass up to about 38 or 39 on flats (I'm 6'2" and about 230lbs).

After several orders from JetsRUs, putting somebody's kid through college on the shipping fees alone, and many hours of changing jets back and forth, I'm on a 38 slow and 90 main jet, and I'm thinking I might need a 92 or 95. After reading what most people are running, I was really shocked to find that I'd need a main jet that size.

Now, she's dragging me up to about 45 on flats. No GPS verify, though. Everything is just relative at this point.

Near the beginning I'd picked up an NR Magic variator, a couple sets of weights and a Daytona belt, but I haven't really bothered tuning it much until I got the carburetor tuned right. The CVT runs well enough to let me tune the carb, and I'm ALMOST satisfied with it. After trying the 92 and 95 to validate my mixture, I'll move on to the CVT.

Oh, and I lied... I'll put up one pic...

Good start! If I were doing a met I'd run a ruckus swingarm and PW:JDM stretch to get it just a bit longer. Makes it look a lot 'meaner'.. Either way good call on the rolling parts choices!
