I really fancy the new GT kit, which is cast iron, which I would fit to a TV200 engine that I would obviously need to upgrade, but with the TV200 gearing. The advantage of this cast iron kit is the out of the box performance, see current scootering issue, plus I can have the carb on the LH side, so as to avoid taking the original battery tray of a TV200 scooter. But the major disadvantage is that I would probably need to do a 1000 miles of running in, (See Edens post about having to run his in). The trouble is that for the last 2 years, i don't seem to have time to do a lot of long runs, so it would take me a long time and would be frustrating, to now run a cast iron barrel in. The other advantage is the numerous re-bores that you can have. But for the amount of miles i do and the potential time I've got left on the conveyor belt of life, this is not a consideration. Disadvantage is perhaps cooling if you have an engine running at very high revs,
With the niscali/ali barrel and i've got three such kits, after 200 or 300 miles, i took it as run in, then ran at full wack, where allowed and never had any issues. In fact on my malossi kit, it said run the engine for one hour, at various revs and off you go, which i did. So for me the advantage is lower running in periods and less fear of heat seizures due to the better cooling.
To keep standard carb side, I suppose I could go with a mugello, but they don't seem to have the same out of the box as the above GT kit; or do they.
So far, which kits are vexing you?
