Buddy 125 Performance Pipe

jperkins · Post by **jperkins** » Sat Jan 20, 2007 7:05 am

Has anyone installed the Prima performance pipe on a Buddy 125? If so are you happy with it?

Thninking about getting one, Tulsa scooters has one in stock and I am trying to decide if its worth the $199

What is everyone's opinion on it voiding the warranty? Worth it or not?

Scroll down a little more and have at it!

Or, click here.

The short answer is, that at the moment no one on the board has fessed up to owning one.

I didn't get to ride it, but they have the prima pipe on their demo bike at Scooterville. They fired it up for me and I did all I could to resist buying one right then since my Buddy is in storage until spring. Unless there are some horror stories about it burning pistons or something crazy, I will be buying one in the spring.

I created a separate post re: the warranty question.

I'm not worried about the warranty. I'm worried about it leaning the mixture out or something like that.

Based on my experience with the SuperTrapp I put on, more than likely the answer to the "will it lean it out" question is; no. Since I did nothing to alter the air INtake, and since the exhaust is freer flowing than stock, the only other thing to suck in is gas. If anything, mine now runs a bit richer than it did when it was stock. Somehow that seemed contrary to what I believed would occur, but then I remembered that when the POC pipes were installed on Bajaj scooters, they had to be refitted with smaller jets. I did some thinking and some study and I believe that until the air intake is made to flow better, you will not lean the mixture out.

I do not intend to alter the intake, however, since any change to your airbox with result in changes in the vacuum, resulting in changes in the way your CV carburetor works...and not neccessarily to the good...

And let me tell ya, a freer flowing exhaust sounds GREAT on a BD125!!

Thanks Keys,

I'd swear I hear my Buddy pinging every now and then and I only run good high octane gas in it. So if a pipe makes it run more rich that should help.

Try just using regular gas instead. An engine designed to run on regular doesn't gain any performance benefit from higher octane stuff (other than possibly some improved additives). Higher octane is designed to ignite at a higher compression, which the Buddy does not have, so you may actually be seeing less performance with that fuel.

[I know this is a 'can of worms', but there you go]

I was actually JUST about to post a question RE the type of gas y'all use. I gassed up for the first time last week, and I used the super-woohoo-ultra-mega premium high octane gas. I kinda/sorta think my scooter is performing worse than before, when Phila Scooters gassed her up with plain-ol' regular unleaded. Good to know I'm not delusional (well at least on this issue)!

Could the premium gas affect the cold-weather performance?

I was stalling all over the place on Sunday (it was reportedly 24F out). I thought it would stop stalling the longer I rode and "warmed up" the engine, but the more I rode, the more I stalled out. It was a total bummer and ruined my day.

PS: What's the "can of worms" you speak of?

Possibly, because higher octane gas will resist ignition more than the regular stuff- which is of course the point of using higher octane fuel in high compression engines.

Anyway, the potential can of worms is that many folks feel- and strongly- that the high-octane stuff should be used regardless of what the manufacturer suggests. IMHO, they are just throwing their money away...

OTOH, I would never consider putting regular fuel in my MINI, which clearly needs the high-test stuff.

Using a higher octane fuel than your engine is set up to burn will cause your exhaust valves to become as toast.

so it is regular (87? octane) or the medium grade (89? octane). I remember reading on another thread that we needed the medium grade.

87 is quite adequate. I live at 3200 ft. and ride up to 7500 ft. and have never experienced any "pinging" anywhere on 87 octane.
