Modern Buddy

Took about 15 minutes to get it on. I corked the breather from the gear box.
I didn't change any jets, just wanted to see how it worked.
Started it up and it runs great, same as stock.

sound=awesome
Have you ever watched the lumberjack competitions on ESPN? It sounds like a "hot saw"

speed = mehh

I lost some top end and it takes longer to get there. I stay in the city so i never have a chance to pass 50 but I want my acceleration back. It's either the same or a little less down low.

I am about 210#, 600 miles on the scooter total.

Anyone have some advise?

Yes, rejet! No fooling around.

It's a nice looking pipe, however I'm not convinced in and of itself, all other things equal, it makes any more power than a stock pipe.

I would estimate that yours is way too lean with the stock 85 jet & therefore makes less power than stock.

Do you still have the foam pre-filter in the airbox?

Delete - double post

the whole setup is still stock except the pipe, I am going to pull the plug and look at it before i ride it again.

I doubt also doubt it will make more power but i did drop 10 pounds off the stock exhaust

I pulled the plug. It looked perfect it was the color of cardboard. I guess I did gain a little low end. I lifted the tire off the ground from a stop without trying.

Nice panels you got there

In order to figure out if your main jet is correct from a plug reading, you need to do a full-throttle plug chop, & preferably on a new plug.

I now have a newborn in my house and can't ride this bike to work in the morning without waking him up. I gotta sell it. $60

like i said before, no top end gain, maybe no jetting change, increased low end, wild sound, strike fear into the hearts of your neighbors

Anybody who lurks this part of the forum and it thinking about the prima, this price is a steal. don't wait to long.

I just look at what scooter works was asking for them, $199.00 Yikes
I also have a gasket and a rubber plug to seal up the emissions system
