I finally decided to take advantage of the nasty cold weather and do some "winter maintenance" on my bike [00 426]. Actually decided to finally do the BK-Mod. Very simple... and it went without a hitch. Right up until the point I was to "observe the squirt" from the accel pump. Well... it appears that there is nothing coming from my accel pump. So... I pulled the pump off and inspected... a little "worn" but still seems to be pushing. Then I realized the carb was pretty dirty. No problem... clean it right?! Well... I've now been "cleaning" it for 3 days and still can't get a squirt out of the nozzle from the accel pump. Actually can't even get carb cleaner nor compressed air out of the nozzle. Must be all gunked up. Not sure how to get the darn nozzle cleared so the accellerator pump can do its job. Contemplating a soaking in a parts cleaner for a while. I suspect this will damage the rubber parts so I will need a rebuild kit. Anyone experience similar situation? I know... my fault for letting the carb get this messy... but it was used bike! The really cool part... the bike seemed to run pretty darn well. I can't wait to see what it runs like when the carb is actually working like it is supposed to!
