I recently bought a 2003 WR 450F and I havent got a chance to ride it a lot I have to fix a few things before I do. I took the carb apart because it was leaking from the fuel screw. I checked the jetting while I have the carb out of the bike. What I found is a little confusing and I would really appreciate help on understanding this. Her are the jets it currently has, MJ150, PJ45, LEAK 70, STARTER JET 65, PILOT AIR JET 70, NEEDLE STOCK 4 POS, FUEL SREW 3.5 OUT.
This setting sound like it probably is to lean right ? Is is normal that the bike runs ok like this ?
I've been searching and reading a lot about this this. The bike runs OK, but idle is not that great and there is a little bog when open throttle quickly. I went and ordered what I though would be a good starting point by the TT database, MJ168, 48 PJ, 40 LEAK and a new adjustable fuel screw.
Am I on the right track ? please any help would be very appreciated,
