[QUOTE="Hick, post: 111169, member: 19514"] For those following at home, I used a hand drill, but a drill press, in the right hands, is probably better. You want to be careful anytime you drill holes in a seven-hundred dollar carb. I used the same spring found on the screw that adjusts the pump timing (PN 5JG-14531-00-00) for the pump stroke adjuster. I’m sure it wasn’t too hard, but I don’t know how I would accurately time the duration of the “squirt.” James Dean, the master carb tuner of cyberspace (so far as I can tell, anyway) ended up with 1 mm of stroke, measured at the rod. Just remove the bowl, measure how much actuating rod you have protruding below the carb body with some calipers, hold the slide open and measure again then subtract for the pump stroke. When I originally did this I turned the screw all in and then jetted the bike, I think you should jet with the pump off anyway, then I just turned out until I was happy with the response. Once I read on TTalk what James Dean came up with I measured what I ended up with and it was damn close to 1 mm as well, so you may just elect to start from there. I loved what this did for my ’00 so much that I did the same to my ’01 before I even rode it (I should’ve taken off that $%&# front tire too). Ricky, I don’t know how I missed that [URL=dirtrider.net/forums3/showthread.php&threadid=12058&highlight=fire]Fire[/URL] thread, that sucks. I know a guy who’d have bought that brake pedal, it looked salvageable... I have also noticed the occasional scent of singed Mesquite and Creosote bushes off my header but I guess I never imagined the potential implications... [/QUOTE]
