Upgrading the R50x

[RushNatU]

The 107mm clutch is too big for the clutch bell.  You can use a 107mm clutch if you buy a different clutch bell.  I am not sure of one that is for sale so I got one coming that will fit.  I will measure it and post the size for you guys when it comes in.

As far as the jets.  I just got the pipe and not the big bore kit.  With just the pipe my spark plug is chocolate brown still with a little fiddling of the mix screw and idle screw.  You gotta set it just right otherwise you'll get flat spots when getting back on the throttle after full throttle.  So I'm probably not gonna upjet.

Thanks.  MRP-Speed's Web site states that these sliders are out of stock.  However, Monsterscooterparts.com has them and I've ordered them.  I'll let you know how these work out.

there will be no noticeable change using ether  one especially with a pipe.
but many pipes come with lighter weights than stock
