Is there any reason not to spray paint it black with high temp spray paint, other than aesthetics?

Mine was painted black the day after I got it. Living 10 minutes from the sea, things rust real fast here. Especially if you ride every day, all year round.

I've heard BBQ paint works well. Make sure its high heat rated.

I’d leave it whatever color it is. Marks and stains just add to it’s character.

How often does the mop n glo have to be applied?

It's basically wax, so Everytime you wipe it down maybe? I dunno. I do it "every now and then". My last pipe was chrome and didn't need it.

Got my pipe (Yasuni R) on my scoot today and oh boy! A ton more power and top end! Didn’t even get it up to full speed though. Should be fairly close to 50mph.
Almost no power from 15-30mph though. Low rpm. Then at 30mph it starts pulling hard and accelerating like crazy again. Lighter weights for the midrange power? Not even sure what’s in there now but I have a new variator and clutch on the way, so I’ll worry more then I guess.
Does anyone have a link to a good guide for CVT tuning? Just something going over exactly where different springs and what parts come in to play throughout the power band?

I'm sure there might be something in the tech section in regards to cvt tuning. What your experiencing is the pipes powerband. Where the pipe makes its most power from. Lighter weights will help with the down low transition. If that's not enough you can also get stiffer clutch springs. Your pipe makes the most power within a certain rpm range. So if you throw in stiffer clutch springs to accommodate your pipes powerband. You can catch your pipes powerband from a sand still. Your clutch won't start engaging until it hits the rated clutch spring rpm. But then it's a different animal. More for straight shot or racing. But very fun...! One of my bikes doesn't come on till about 10,000 rpm. But when it does . I'd start with the lower roller weights first to see if you can get it to hit any sooner. EDIT: A lot of your informations gonna be in the link I sent you from tuning matters.

Defiantly get some lighter rollers. Those sound way too heavy. Sounds like the right pipe though 😁

Going to order a roller tuning kit today. Sad thing is, I just bought one for a 15x12 variator, which arrives today, and the new variator I’m ordering today uses 16x13. Can use the smaller set for my girlfriend’s scoot though.

A little info in the CVT area here : www.49ccscoot.com/faq/faq.htmlAll sorts of tidbits here : 49ccscoot.proboards.com/board/42/transmission-techLighter rollers and stiffer clutch springs are the norm when installing a tuned pipe. Stiffer clutch springs get RPM up off the line and lighter rollers raise RPM basically everywhere else. Those 2 things are usually enough. Sometimes people add a stiffer contra spring, which puts more tension on the belt and raises RPM. The contra and rollers have to work together, actually in contrast to each other with the contra spring trying to push the rear pulley closed and the front open and the rollers trying close the front pulley and open the rear pulley. You can go to extremes and aim to stay as close to peak power as possible all of the time with all sorts of CVT parts, but the clutch and roller tuning will likely get you to a much better place. Not trying to spam you, but I'm getting rid of all of my tuning rollers for $10 shipped in the classified section. All used, but if all you want is some tuning rollers they may do the trick. There are some decent rollers in there that will hold up to regular use, but I'm not sure what weights they are. You would have to have a small digital scale (which I advise for any CVT tuner anyway for something like $10 online).

Here is some more information for you. Popular pipes on a 50cc air cooled cylinder www.pedparts.co.uk/c/asset/sports-pipe-blog/50cc.pngSame pipes with a Polini sport 70cc kit www.pedparts.co.uk/c/asset/sports-pipe-blog/70ccPolini.pngI know a lot of people like the next R exhaust. I am not a fan. It's ok. I had one on my slider. With a standard cylinder and a 17.5mm carb the Yasuni R was about 7 MPH faster when I changed it. Like Lucass2T said though, the reason I brought the R was it is a great everything pipe. Even though I told my wife I wouldn't tune this scooter. It's just for riding to work on. with a stock cylinder it works. I know if I want to fit a 70cc kit. It will work. Fit a 50cc race cylinder. It will work. If I sound like a Yasuni fan boy, let me tell you they do rust. Great info, thanks! I have a Leo TT pipe I have not yet used for my Vino 50 and this tells me a lot. I like the good power numbers and that it makes power down low (not as broad as some others, but. I also plan on a 70 BBK soon and this covered that question as well! Thanks again!
