looking for help with california klr that has carb problems

[akrider2002]

I just got my A15 out on the road for the season. We still have snow on the ground, but at least the roads are clear! Anyway, somewhere over the course of winter storage the exhauset has developed a rattle. The question is; is there any way to get into the stoch silencer and see what is loose? I can't see any place to open it up. Or, is my only option to replace the silencer? If the choice os to replace, any suggestions for an aftermarket silencer? Mark R. Anchorage, AK A15

Remedying the problem usually involves removing the carb, thoroughly cleaning it, inspecting the coasting enrichener diaphram for the slightest pinhole, and then reassembling it and seeing if the bike works better. Changing the jetting without doing the cleaning first is a waste of your time and money. If the bike is bone stock (air filter, airbox, exhaust etc) then the jet kit is totally unnecessary.

The pilot jet is clogged, most likely. The carb need to be removed, stripped down to the casting, and then soaked in a (very, very nasty) carb cleaning solution. http://xd8ad0695.ip.e-nt.net/klr/how_to_clean_carb.jpg After a soaking, you rinse it with water (or whatever the directions of the particular cleaner you bought recommends) then blow out the passages, particularly the pilot circuit ports and where the pilot mixture screw goes, with 100psi compressed air.

That's not the main jet. The mixture screw you are trying to reach is the pilot mixture screw. sagebrushmachine.com sells a very good tool for adjusting it with the carb installed.

Don't call Kawasaki. I think the guy who designed the bike has died or retired by now anyway. Asking questions on this list will get you answers from people who have been riding and maintaining KLRs for many years. Some people are on their third or fourth KLR, some own three. -- Devon Brooklyn, NY A15-Z '01 KLR650 '81 SR500 cafe racer "The truth's not too popular these days....."
