50/70cc Racing Exhaust

[WisconsinKeyWester]

Hello Everyone,
Just thought I'd tell those who are looking to upgrade their pipe what a benefit it is. I went with the MRP 50/70cc racing exhuast and I say 50/70cc because this pipe will work with my stock cylinder that's a 50cc and it will also work with a big bore kit it at 70cc if you chose to upgrade later on. For performance I was running around 40-42mph without the pipe but instantly when I put it on I would get 49mph on flat ground and buried the speedo over 50 down any kind of decline. N-MP-02060 is the part number. This pipe will work with a little tlc. You'll have to buy two 3inch long 10mm standard thread screws because the stock ones are too short. Also make sure to take care of your stock gasket to reuse because its just one less hassle. Also you'll need to either remove or bend your main stand, I took mine off and it looks pretty cool with just the kickstand.  http://www.whidbeyparts.com/SPD/n-mp-02060--80000CD8-1200671303.jsp  if you're looking for a link.

yeah, that is a pretty good increase for just a new exhaust. personally though i wouldn't spend that kind of money for a performance upgrade on a moped. save up a lil more and you can buy a cheap bike that will go a lot faster.

yeah  they go fast when you do a few things to them
if anyone wants unlimited cdi's or the weights let me know
heres the link to the cdi:

and the sliding weights :

and the clutch:

the cdi doesn't work on the R50x sorry ...also the TGB 107mm clutch doesn't work on the
newer TGB's

if you just do the cdi & weights (go 9gr) and remove the ring in the variator you will get around 45mph
the total cost is about $65  plus shipping.
