Just picked up my new 650 R last night and started to break it in. Dont have much money to spend But would like to do a little to help it out power wise. Also I have read here on TT that they are lean when new and could cause it to run hot? So should I rejet now to be on the save side? If so does any one know what the stock size jets are? I tried a search but could not find what I was looking for. Probly looking in the wrong place. Also what is the best air cleaner for this bike and I read that you can cut away part of the exaust tip to help it breath ? Anyone have any details on this to help me out? Thanks Oh. I'm short. where can I find that lowering link and is it any good?
