Hard to start 2002 WR250F Yam 2002

Subject: Hard to start wr250   Today at 7:02 pm
does anybody know a couple tricks to get a hard to start 2002 Yam WR250 running? key points:
- rebuilt the carb
- new spark plug
- good compression
- clean new gas - premium 91 octane
no electric starter, so I am kicking this thing

I replied to this very question on your other post of it.

Wrong message board, honestly.
Since the WR-250R and WR-250X are not the same machine as any model year of a WR-250F, you won't be typing to many other WR-250F riders.
For just one example of the differences, the WR-250R and X have fuel injection.
So, you really have to specifically be aware of the letters R, X, and F after the WR-250 part, as we're talking two completely different designs.
Thank some psychos on some Yamaha Motor Co. sales and marketing team for making that easy to understand right off the bat - even Yamaha motorcycle dealer salesmen don't all know about the differences. ;)

I do happen to ride a 2002 WR-250F, myself.
PM me with questions if you want.

Not sure if this is relevent BUT...
I had a 02 yz426f. When I first bought it the owner was selling it because it was too hard to start. I took it home and cleaned the carb. No difference. When I checked spark i found it to be very weak. So I bought the same plug that was in it which was a champion. Installed the new plug and got the same thing, very week spark. So then I looked up the correct NGK plug for the bike and installed it...BRIGHT BLUE spark. started first kick for the next 2 years I owned it. Weird thing was that the champion plug x referanced to the ngk. Just difference in brand I suppose.
