Well I installed my new rev pipe last nite(10 min. install,no nitemares like I've heard of,perfect fit)anyway did the airbox mod,actually just sawed it in half so I would have a mount for that relay or whatever it is,installed a new unit-filter ,still have the stock jetting,145 main and 42 jets.What a difference,I was getting wheels in every gear,like they told me it was nite and day.Gonna move the needle clip to the second pos. from top tommorow and go riding.Cant wait.Glad I decided to keep it instead of selling for a kx.Fork Springs are next.OH yeah I think the neighbors may be pissed,it was 10:30 when I got to it last nite,had to do a few laps.glad I had a lite.
