Hi, I am repairing an R50X and have the carb stripped down and the main jet is a 53. I want to either put in a 60 or slightly larger. I plan to remove the variator spacer to add a little performance. The rest of the bike is stock.
what top speed am I likely to get and where can I get the 60 or 65 main jet from as I am in the UK.
Thanks
Jimmy
