I just finished my search of 13 pages related to JR50 mods. I gave it a good honest effort before I started this thread, but did not find the specifics I was looking for. My dilemma is the same as most everyone else who posted in all the similar topics. My son has been riding since he was 2 and started on the JR50 with training wheels that I bought new. Last summer we finally got off the training wheels and he wants to try some motocross at the local track. I don't want to spend the money on a new bike before I know whether or not he really enjoys it. It is obvious he is at the limits of the JR50 in stock form, especially suspension. I read and read all the posts my search returned and found lots of mention about lots of mods, but not much specific info on how to do them. I'm mechanically inclined and am certain I can perform most of them with the proper instruction. Could someone please post some links to help me perform the following mods:
"Jet" removal (the jet the threads say is not needed)
Carb tuning ( which screw does what)
Where to buy aftermarket sprockets and what size "works"
Who has instruction/sells part for the "hidden gear" mod
Oil injector block off for premix gas
I hope the replies help others in the future. Thanks in advance.
