I have a WR that is converted to a road racer. Will run Pikes Peak this summer as well as numerous road races this year. Here's the specs: 2008 WR450 J&E 12.75 Piston Dyna programmable ignition STM slipper clutch Kibblewhite ti valves & springs Ported Head by Orient Express R6 front suspension with Ohlins 25mm cartridges Ohlins custom rear shock YZ close ratio transmission Oversize rads Excell spoked wheels, 2 sets, 1 set for rain tires Brembo master cylinder Woods rear sets. Ferris Ion battery Full body work Dyno: 59 rear wheel HP Carb untouched/stock except for some main and needle work on the dyno. The bike has gotten super hard to start. The electric start works great but the bike just won't quite get running. Leakdown test at only 8%. Adjusted valves, changed coil, changed plug. No difference. I'm pretty sure the engine and ignition are fine so this leaves the carb. I use starter rollers to get it going and once it is running its awesome. But need to get back to where it just fired right up off the starter motor. I'd like to get the carb tuned to the max since its stock. I would like so help on who to send it to or what to change out. Any help or comments would be appreciated.
