Hey guys.
Sorry I have not been around much. I started a new job at the end of April and I now work some crazy hours. I haven't been riding my scoots that much but selling them will not even be considered.
I have to say that putting big bore kits on them has been the best investment. I wouldn't think of going back to stock cylinders.
The good news is, I'm ready to take the next step and start pipe shopping.
I did an experiment the other day. I took off the stinger of the stock pipe. The scoot did not get any louder!
I was expecting it to be much louder like it was when I took the silencer off my dirt bikes.
Anyways. What are my pipe options?
I have a Motorino Supremo and a RSM M-80 model.
I would say they have an identical bolt up pattern as a Triton or Keeway Matrix.
I'd love to find pipes in the 100.00 range, and used is OK. I can be patient and wait for the right auction.
I have seen some comments to know to avoid the no name "performance pipes".
I know LV makes a pipe for a CPI Oliver which I'm sure will work well, but I'd really like to know all my options as far as pipe makers and what will bolt up or what will need a fabricated mount.
Any suggestions?

Most minarelli pipes for the Aerox 50s and Zumas should be able to fit. The Jog pipes are intended for scoots with more narrow tires, so they sit in farther and may not work. For $100, you aren't going to have many options. Either you will need to wait for an eBay auction to pop up or search scooter forums in the classifieds sections. Yasuni, Leo Vince, Stage 6, and Polini are a few good brands to look for. There are more out there, but your choices are mainly going to be limited by what you can find for that low price. If you just want to see soem of the pipes that are out there... www.sip-scootershop.com/EN/main/base/Results.aspx?d=(sco,ape,lam,old,px,sma,max,atv,mot)&s=11a7dc44ce5d482bb9f26bec38751ed1&a=1&sort=0&uc=(1d5dedbf24d143ac9db25ce00b5e13b5) |

Thank you for the information.
I'm willing to go higher on price, but I would rather gamble on a used good pipe in case it doesn't perform the way I hope it will.
Is there really a difference between a 50cc pipe and a 70cc pipe?
It seems some are marked as to what they are for and others are not. It is confusing.

A Leo pipe seems to be a good design at a reasonable price,be careful about off brands as some are really bad..

I have seen you post that before and I am staying well away from generics! Thanks!
I'm actually looking at a ZX or a "Hand Made 70" (for a Zuma). According to LV, the "handmade 70 begins where the ZX left off".
Do you think there is much difference?

I have a Leo Vince ZX and an SP3 and they are both good pipes that can be had at reasonable prices. I'm probably getting ready to buy my 2nd Leo Vince 100cc pipe, so that should say something for them. Fitment on them has been excellent from my experience. I don't really know anything about their other pipes.
The pipes for larger cc engines may have larger headers, stingers, or other design features to better suit different needs. Most of the time it is suggested to buy a pipe that will be suitable for a 70cc even if you have a 50cc. I'm sure a 70cc pipe doesn't always work to peak effieciency on a 50cc, but it gives the option to upgrade without worrying about needing a new pipe.

Thanks.
I have never seen it stated that a ZX is for 70cc or for 50cc, so I never really knew.
If I am reading it right on on LV website. I am looking for part number 4575 (ZX) or 4575R (ZXR) Is that right?

Thank you.
Now I confused myself. I thought a Zuma and Aero used the same exhaust.
Did the Aero pip require a mod at the back mount?
It looks to me like some of the Zuma pipes require a minor modification of a couple of strips of metal to bolt up in the rear.

They are the same pipes, the mount is just a tad different on the backspacing....
A homemade one inst too difficult. Some of our members have fabbed em up pretty easy,
w/out major tools or skills.

I'm not exactly sure what is different on each model, other than maybe backspacing like 2strokd said. I guess I've been lucky, but I've never really had to do any more than adding spacers to my exhausts other than manipulating a bracket some on the Leo SP3 that was made for an Aprilia.

Well, I went with a 4575c.
My original plan was to go with a pipe without chrome but the price on the 4575c was too good. $109.00 +25.00 to ship for a new pipe.
Thanks for your help, guys.

That is a good price. Let us know how it works.

I got my pipe on Friday. I mocked it up after I got home from work Friday night and worked on it from about 12:00 AM to 2:00 AM.
Getting the re-stricter cone out was pretty easy.
I'll have a permanent setup fabricated/painted and hopefully take a picture of it tomorrow.
The pipe fits well and I'm using a combination of the mounts that came with the ZX and the mount cut off of my original pipe.
The only clearance concern is at the bottom of the pipe as it touches the frame bar under it when the scoot is on the center stand. The frame bar may hit the pipe after going over a big bump and the suspension fully extends. I don't know if I should grind the ring at the flange so the pipe is up and 1/8" higher providing more room between the pipe and frame.
The pipe is really a work of art. It looks so nice.
I took it for a test ride. The first half a mile was friggen amazing. WOW!
It was going like a bat out of hell up a big hill, and then, I lost power considerably. I think the auto enricher kicked off and I leaned out.
I babied it home so I wouldn't damage anything.
I knew I'd be out of tune.
I am still running an 85 Main which I had in there with the big bore kit and stock exhaust. I can go to 88, 90, 92, 94, 95, 96, 98 or 100.
Any suggestions?
I guess I should go up one at a time to compare, but I don't know if a pipe addition should be a bigger jump.

I'd probably start at the 95 to be a little more on the safe side. Do plug chops from there and if possible go a set distance at WOT and record the MPH you get over that distance for each jet you try. If you are able to, record te RPM as well. No matter what gives you the highest speed and RPM you still check the plug to be sure it's rich enough to be reliable.
None of my scoots have any frame under the pipe. Not sure what to tell you there. If you are considering removing the ring on the header, you might wanna try to measure your cylinder's exhaust port and the diameter of the header pipe with and without the ring. That way you can decide if removing the ring or griding the ring down would be a better option to get the header to match the port. Either way, you'll need to start using a flat gasket instead of the normal ring style gaskets.
