I am waiting on a service manual. But until it gets here can someone tell me what size main and slow jet is stock on a 1997 RM 250 2 stroke. It's a Keihin carb. It now has a 45 main and a 155 slow. Thanks

I know the main is 175, but I'm not sure about the slow. Are you sure your numbers are correct?

You have that backwards.. or an extremely rich pilot.

stock: 175 main, 48 pilot

you should be alright on the pilot but your main sounds pretty lean. What type of work is done to the bike?
