So I'm guessing that 150 & above scoots don't get modded as much as the little 50's do, but now I finally have a 150, I'm wondering what the most common upgrades get done to 150's? Maybe new pipe or carb?

Maybe new pipe or carb? 150's get modded like crazy. I'd start with a good quality variator, unless your bike is running too lean from the factory, in which case you might have to look at a carb first (providing the factory one is garbage). With a GY6 150, it's all about how fast you wanna go and what is the limit of your budget. There is a larger range of 150 performance parts than there is for the QMB139 50cc engine. Matt

Thanks Matt! My gy6 150 is a little different. I think it's a gy6b, but not sure because it's liquid cooled. I'm not sure which gy6 150 parts are compatible. It's made by CFmoto, E-Jewel model. If you could let me know what parts (especially exhaust) are compatible that would be great!

I think you can put an exhaust on there... and that's about it. Maybe. I've never actually had one of those bikes in house to R&D, so I'm unsure which exhausts fit unfortunately. That's one of those handful of bikes that I think is best to ride stock. Matt

Yeah, I figured it might be hard to find upgrades when I bought it.

Yeah, I figured it might be hard to find upgrades when I bought it. Unfortunately yes. I was doing a bit more research for you, and yeah... I've got pretty much nothing aside from transmission parts. So a performance variator is probably in the cards for you, which does make a difference, but that's about it really. Unless you're really unhappy with the stock performance of that bike, I'd say ride it as is. Matt

Since we're talking performance parts for 150 GY6, maybe now is a good time for noob input (namely yours truly... sorry for the half-hijack jdl357, but this seems to hit the nail on the head!) I basically haven't touched the CVT in the 3600 miles that I've driven the GY6 other than upping the weights by 1g, replacing belts and other general maintenance. I need to get the new carb and engine performance finally up to snuff first, then, something I've noticed, it's not obvious that the variator is getting full range out of the drive face. When we talk "performance variator," what exactly would this do? Higher top speed, better acceleration, more tuning options, other? I get the gist of how CVT works but lack the first-hand experience of actually swapping things for a good tune. Not sure what to expect fugaziiv?

When I had my 80cc 2 stroke I got a polini hi-speed variator as my first upgrade. Man what a difference! It had way better take off and almost 10 more mph top speed! Polini and Malossi make 2 of the best variators I know of and it's definitely a worthwhile upgrade!

I get the gist of how CVT works but lack the first-hand experience of actually swapping things for a good tune. Not sure what to expect fugaziiv? I often tell customers here that there is more bang for the buck locked in a stock transmission than anywhere else on your scoot. With a good variator, often times you'll see both an improved top end and acceleration, and it comes from the difference in the ramp profiles. Often times it'll also provide a smoother feel through the rev range. There has been a ton of R&D done by the performance houses on variator tech... and the stock designs are honestly just not very good. The stock variator designs on the GY6 and QMB are ancient, and when they were developed, they were good enough but that's it. For most Chinese engines, a variator upgrade is a no brainer. While Polini and Malossi are two of the very best brands making scooter parts, and on a QMB139 or Honda GET engine it's almost impossible to do better than the Polini in particular, the GY6 has some really good options that are easy to recommend and quite a bit more affordable than Polini. I'll list some of my favorites here: www.partsforscooters.com/169-263_Dr_Pulley_VariatorThe Dr. Pulley is just a helluva kit. The ramps are long and it's really designed to work with sliding weights. It accelerates smooth and pulls all the way to the top. It's been a best seller of ours for as long as we've been importing Dr. Pulley. www.partsforscooters.com/169-487-Ban-Jing-VariatorThe Ban Jing uses longer ramp profiles and 20x12 weights (instead of 18x14) to give a long smooth pull to the top. In house this has been a popular choice lately. www.partsforscooters.com/128-21-Koso-GY6-High-Performance-VariatorThe KOSO has a racier profile. It's not as smooth, but it accelerates pretty aggressively. If you're looking for that characteristic, it's ideal. www.partsforscooters.com/169-24The SSP-G PTFE variator is kind of a dark horse. It's our design, and the ramps are designed to give improved performance all around. This one is fun because it's a popular choice with a bunch of the GY6 tuners in the US, who buy it from us and quietly package it in their GY6 builds with great results. www.partsforscooters.com/146-12-Polini-Variator-Kit-GY6And naturally Polini. It's the variator that all others attempt to measure up to. If you've got the cash, just buy this one, and don't look back. We've got a bunch more to choose from, but this will give you something to go on. Matt

Thanks for the info. You just convinced me to add this to my list of winter maintenance items. As much as I'd like to get a before-and-after effect, I really have to hold off on installing this before riding season. Like, yeah right.

Variators are a big deal and make for real change. Many of us who tune these little engines have whole collections of them. When we were drag racing bikes, we went through many before deciding on Dr. Pulley for those builds. Matt

Well, the criteria for drag racing bikes is a bit different than that of a street or track bike, and also we wanted to get the most out of the sliding weights as well. Additionally, the Dr. Pulley variators are fairly tank like, and as we were working with N02 and the Dr. Pulley HiT clutch (which basically locks instantly when set up to do so) durability was indeed a factor.

Matt Anything special about the drive face on the Dr. Pulley Varilator? Sounds like something I'd be interested in if it's made for sliders. I use an NCY with sliders and it works... but you know, these parts just add a little bit of performance. Maybe it's worth the little bit... but that drive face is ugly for an open CVT. I'd use my NCY drive face, but not if that DP drive face is meant to work with the DP varilator.

I'd use my NCY drive face, but not if that DP drive face is meant to work with the DP varilator. The angles on the DP drive plate face match up to the variator itself. They're a mated couple and should be run together. Dr. Pulley is really good about providing a drive face if it's needed/recommended for their product, and not providing one if it matters less. And yes, it's specifically made for sliders. Dr. Pulley is a performance first brand, NCY is an aesthetics first brand and that's reflected in the visual presentation of both for sure. I guess it just depends which is more important to your build. If you want better performance than the NCY with better visual presentation than Dr. Pulley (which admittedly is lacking) check out the 115mm Ban Jing setup. Matt
