Here it is guys. I think it is going to be way better than stock at lower than full racing price.

Looks like a good kit, a good price as well!  I've read good things about NCY stuff!  The only thing that looks like is missing is the belt.  You may want to ask, if you haven't already, if the stock belt will work well with that kit.  It may be nice to start with a new belt anyways.

That's a geat idea. By the way do you know the number of the belt cross referenced over. Mine just says bando and a bunch of numbers that I haven't found on any sites. most are like 669-18-30, or 729-18-30. mine has no numbers like this.

I found this page while looking for the stock length when I did mine.  It looks like your belt is 736mm X 18mm.

Thanks for the kind words guys. I am currently expanding my parts page to include Kymco parts so you should see me around more often.

Cool Jeremy good to see you over here. Kymco scoots are great and we need a good supplier, which you have proven to be.

That's awesome!!  We need more reliable knowledgeable people to buy parts from!  I think it's great when shop owners are active in their particular community as well!  It's makes them privy to their customers needs and is a ultimately advantageous to both parties! ;D

Got my rings yesterday and finished putting everything together tonight. Only rode four miles, but all seems well. Great throttle response, lots more power! Only went up to 35 and let her coast down a huge hill to pull the rings up in the groove and seat them. By the way that hill was hard to do more than twenty up before and I hit that at less than half throttle. So far I have the bbk, ported and polished the heads, opened up the exhaust and intake,open air filter, and 5.5 gram rollers. Next is the transmission kit. I'll keep you updated as I break it in and put the trans kit in.

That's great!  It's always nice when everything works out the way it should!  Just make sure you do a couple plug chops to make sure you have the carb adjusted correctly!  Did you happen to measure the new rings, I'm assuming they were within spec?  Were the other rings the wrong ones, or where they just flawed?

The new rings were pretty much right on. I took about .001" out of both to give a little extra room since these engines run hotter than a water cooled. So, they ended up at .008" top and .010" bottom. And yes it is nice when everything comes together nicely. I figure I will need a little tuning on the carb, but it seems to be right on I just upjetted two sizes. I haven't done more than about a 2 second full throttle pull yet, but I can tell that opening up the head, intake, and exhaust helped air flow tremendously. I also took the carb completely apart and ground down the throttle plate screws and sharpened the leading edge (of the throttle plate) to improve air flow through the carb The intake and exhaust note is louder and deeper. I have an iridium plug, but I'm gonna make sure I have the carb just right and the motor broken in before I put it in, so I can see how much of a difference it makes. I'm gonna order the trans kit tomorrow, have it in three days. I'll keep you posted of my progress.
