i would spend the extra bucks for the airsal on provoscooter i've heard good things about provoscooter and i have heard a few too many bad things about ncy's build quality and attention to detail to buy anything motor-wise from them but it is nice that the second one comes with a head with larger valves i wouldn't mind having one of those

[hungryrussian]

keep in mind though that aluminum could be a little touchy and or easier to damage/blow i don't know much about how they coat the cylinder but i definitely know cast iron is tougher than aluminum

[Kenho21]

Right, I'm just kinda worried about the durability of the aluminum. I do plan on doing a decent amount of driving with nearly wide open throttle and worry a bit about it blowing of seizing. I'm kind of getting the feeling that with the cast iron I may get some more life out of it.

But so far everyone I've talked to has had a different opinion, so that's why I posted this topic to try and get some feedback from Kymco and scooter enthusiasts themselves.

I know NCY is a Taiwanese brand which is a good thing and have heard great things about Airsal but hearing some negative things from people on here about NCY makes me second guess...

If you read what wordslinger wrote about the ncy clutch, I think you would give them a miss. I was a fair while ago, so I don't remember where it was. It turned out he had to machine parts of it to make it work properly.

[hungryrussian]

yea i remember him having a lot to say about their quality control.. try and find a Naraku cylinder that's what i'm using and no complaints so far

[Kenho21]

Finally done bugging you guys with all the indecision on which kit to order and went for the airsal, mainly because of reputability. Can't wait for 4-6 business days to get here!
