Well, it wasn't too much trouble but I thought I would let some of you know what I found out in my quest to jet a 426 with BJ baffle, airbox snorkel removed. I found the easiest jetting was basically stock jetting with a ELN at #3. It starts right up, runs strong all the way to WOT. Fuel screw is 1.5 out. I could possible look into doing more tweeking but it runs great and it only cost me $12 bucks for the ELN from the dealer. BK Mod wasn't needed, it timed at just under a sec. stock. Now that it is running great, I am selling I bought another toy (Jet ski) and need to sell the WR so I can afford the ski and still get another, cheaper dirt bike. Probably a late 90's 125mx. Or maybe, I will just keep it. If it doesn't sell, it will still be ridden. I think the jetting quest is finally over for me though. I tried a few mains and messed around with the fuel screw. Good enough, after all this is not a 250mx, what can you expect? It still hauls ass faster than I can ride it. Anyone out there want to try and convince me to keep it?
