Bk mod no squirt!?

8 posts in this topic

Hey Guys,

I just finished the BK mod on my carb. I've got the bike back together and the sub frame off and there is no squirt at all. The gas is on so the bowl should be full. I completely backed out the new screw. The only thing I can think of that I messed up on is when I cleaned the carb I sprayed the diaphragm with carb cleaner. Could this be why it's not spraying? Any thoughts would be appreciated..

Thanks

If you can see the pump rod operating, one of the pump check balls may be stuck open or missing. Trace the fuel circuit through the pump. There should be one on the inlet side and one on the outlet.

Sooooo the diaphragm was in upside down...:smirk: All is good there now and the pump it's squirting great. Thanks!

I did the best I could adjusting the timing and duration before it got dark and could not see. I road it around a bit and I feel like some changes in jetting are needed. At quick blips of the throttle when not moving the bike dies sometimes so I need to look into that. I also noticed that the pump spray is pretty weak after setting the duration at around .35, is this normal?

Any ideas on jetting after this mod? My specs are as followed...

Location: Phx, AZ

Elevation: 1200 ft

Temp: 70 to 110

Humidity: >10%

Main: Dynojet 165

Pilot: 45

Leak Jet: Not Sure

Fuel Screw: 3 turns out

Needle: Dynojet needle 2nd Clip

Any help would be awesome..Thanks!
