Need Help - 46MPH MAX! :(

[Cunni]

Hi, I own a TGB R50X, it goes around 35mph up a slanted road and 46MPH Max going down hill! The bike starts to shake and can't handle anything when it hits that speed. I am a spastic when it comes to doing anything with my moped and so I would be taking it to a shop near me to get any mods done.

I got it de-restricted which it now goes from 34mph to 46mph. I'm in need of a list of things that I can do to get my moped up to speed with the rest of my mates. They are getting around 50MPH and 55MPH downhill!

Can someone give me a list of things that will increase my top speed so that I can achieve 50+MPH?

Cheers

so do they also have morini motors or minareilli motors?
the first step is to ask your mates what did they
do to there scooters . that will give you a idea what needs to be done
to match their speeds. have they put in a bigger cylinder or pipe or variator
or changed the weights or springs and maybe the gear set.
which the R50X  by the way has a higher gear ratio than the other TGB's
the R50X like the other TGB's  can be de restricted but
i haven't come across any CDIs that works on the R50X which will allow the
motor to make over 8,500rpm or so & it will always limit the motors
speed.

some R50x's have had a wire disconnected and it will turn off the limiter
but it depends on the year and the country your in.

i just did a mod on a 50cc motor and it was 70cc kit ,up jet - idle and main,
both sets of springs and sliding weights . the top end went up maybe 4 mph
can't tell for sure because the needle is getting pegged .
but the acceleration and get up and go hill climbing  is about twice the 50cc had
and its  really aggressive in all parts of the throttle

Also, could this one possibly fit on? http://whidbeyislandmoped.com/cart/index.php?main_page=product_info&cPath=1&products_id=244

It says - "Expansion chamber with silencer for the Morini motor
found in many scooters including the TGB 101, 303r,
Key West, Key Largo, R5, (not R50X), Suzuki Address
in standard and big bore 70cc."

well ,i'm partial  to anything from Whidbey Island Moped.,, ha 'cause its me!
i'm also a MRP dealer. fyi; about shipping pipes, they are expensive to ship overseas.
may add $80-$100 to your cost.

there is only one pipe that i know of fits the R50x, its the MRP R50X pipe but
it has been out of stock for a year or more. thats why i don't have any .
there are 3 other pipes that fit the other TGB's, but they don't fit the R50X.
