I have a stock 97 yamaha xt350, I have a problem with slow trail riding in colorado, It acts like it's loading up. I have to stop and rev up the throttle for it to clear out. If I'm riding fast all the time I don't have a problem. Also I found a pipe offered from supertrapp, but aftermarket parts are real hard to find, can't seem to find any intake stuff, any help on what to do with my riding problem and also what I can do to get more power.
