Hello fellow thumpers, I am new to your site, so i thank you in advance for your advise and opinions. I am an advanced enduro/offroad rider switching from a yz426f to a 07' 525 exc( 50 state street legal) and loved it for the first 20 hours. I broke it in on the street for the first 3 hours, and did the required maintainace for that first service.The next weekend I rode 400 miles in the dirt, (single track to atv trails) at mostly higher speeds(35-80mph) with no problems, just some poping in the upper rpm's on decel because of how lean they had to jet it to pass CA green sticker. I trail ride (90%) and ride on road when neccesary to work or ect... When the hour meter got to about 25-28 hours Inoticed on a hard trail ride that the bike would die in corners and was hard to start again. Still ran good once it started again, but would die at slower speeds. After the few problems I faced, I decided to still race my first enduro. -first 15 miles= good -@ mile 28 =ktm was boiling over because of VERY SLOW single track corse. what do I need To be enduro ready?
