I finally got my 87 js550 to run and ride for all of its glory. I bought it early this spring for $100. some of the best I ever spent. It is totally stock. Here's the question. what can i do to make it so i can ride it at full throttle. It bounces when i get to about half throttle even if i am on glass. would a top loader intake from R&d solve this issue or make it worse. also, any tips on learning to ride better would be much appreciated. I can slide it sideways for a second or two, it usually dumps me off but its great fun. I've been trying to jump wakes with it but to no avail. any suggestions on getting some flight time?
