I'm planning a similar job on my PCX150, it took me quite a while to get the right grease from Shell. It looks like the components on the TMAX are quite well-engineered, that probably explains why they last so long (I'm considering buying a 2008 with 189k kms) - long distance commuting and a FSH.

Dear 49ccScoot. Question. I recently purchased a Kymco AK550. As you know, this scooter is basically the bastard child of a Yamaha Tmax, and a BMW C650 Sport. This scooter tends to run out of air right around 85mph....though it WILL hit 115mph if you keep the throttle pegged. It just seems like my Scarabeo 500ie (with drpulley sliders, and larger rear tire) was MUCH quicker and faster on the highways. So far, this Kymco AK550 scooter is stock. Would it be worth installing a JCosta variator to this scooter? What about bigger Vstacks and an airbox? An aftermarket exhaust? If any changes...what order would you do them in? Thx from a big fan.

@49ccscoot

3 жыл бұрын

I actually don't have a lot of experience with performance mods on the big scoots because to me the gains are small for the amount of money that they cost. If I were in your situation, I would look for a community about the Kymco AK550. Find people with real experience on that specific model that can tell you what works and what doesn't. If you're lucky, something like different rollers/sliders to get the RPM in a different range will improve it without a lot of expense or maybe you'll find that there is some identified weakness for that model, like the variator or exhaust. I can tell you that for my TMAX, I could put thousands of dollars into big boring and cams and end up with a few HP. At that rate, I thought it would make more sense to trade in for a 650 or get a motorcycle if I had to have a lot more. This is coming from someone that loves to modify scoots, but there's a point where the dollars make no sense at all. Sorry this isn't the precise answer you'd like, but that's honestly how I would handle it with my own scoot.

Hello sir , I admire your knowledge about cvt's and I'm trying hard to figure something out but I am struggling. I have a myroad 700i Kymco , and I have put lighter rollers ( from 30 to 21g) and a stiffer spring ( silverwing malossi white) but my rpms lock at 6000rpm and sometimes to 5500rpm. Its funny that my rpms were higher with 25g sliders but they kept rolling inside vario so i had to put back rollers. Also there is some strange nosie like belt rubbing or slipping or something, that I can't figure out what is causing it. When i hear that sound usually around 35-4000 rpm i can feel the light vibration on the steering wheel it almost feels like I'm riding with a brake appiled. Sometimes the sound dissapeares and the bike pulls crazy good. Sorry for long post hope you respond , thank you!

Are you certain that RPM was higher with 25g? Staying that close in RPM across 11g per weight, plus a stiffer spring that should increase RPM, seems like it would have to be RPM limited somehow. My first suggestion with issues suspected to be CVT related is to do a very thorough inspection of all CVT parts.

If you can make them light enough, even half the weights that it uses could be enough (stagger them with whatever the lightest weights are that you have around).

If it's just the axle (bolt) itself, all you need is the inside diameter of the wheel bearings that you're using (most commonly 10 or 12mm) and the distance between outsides of the front forks where the axle passes through. Length of the axle needs to be just a little longer than the outside fork dimension so you have enough threads for a nut. Thread pitch doesn't matter as long as you get a matching nut.
