Title: 1987 KX250 Jetting Baseline for Standard PWK38
Post by: Faceplant on November 11, 2019, 03:54:17 PM
Looking for a good starting point for a new Standard PWK38 for post Classic racing. Searches have failed to find anything other than what was stock 32 years ago. Has anyone upgraded from the stock round slide to the standard PWK38mm? What jets needle and slide did you run?

Running on,
Super Premium Fuel
40-1 mix

Bike 1987 KX250 with,
Stock Porting
Stock Pipe
Rad 12 Valve Block

Environment,

Thanks in advance for any suggestions.
