seekthedeep posted a topic in DRZ400/E/S/SMHi guys! I own a DRZ400s and have a question about taking a different approach to the standard leaky petcock Fix. So, I just ordered the fix a lot of people recommended on here for the leaky stock petcock: The Petcock off of a Yamaha Raptor. I did this after looking for other vacuum petcocks and not finding good alternatives. However, I found a part made by Pingel, and was wondering if it would work in conjunction with the Yamaha Raptor petcock, in order to give me the perks of the Suzuki Vacuum Petcock, without it's shoddy craftsmanship and limited life. Could one of you guys help me out, and tell me if this would work? Do I just place the Pingel Inline Vacuum Valve on the fuel line between the Raptor Petcock and the Carb? Or does the Pingel Valve work as a petcock all on it's own? Thanks guys. Besides hitting the dirt often, I am trying to use my DRZ to zip around Los Angeles and make deliveries with postmates/grubhub/etc, so I would not like have to shut off the manual petcock every time I hop on/off the bike. Thanks again guys!
I've got a 1999 Suzuki RM125 (PWK carb, ProCircuit Exhaust). The settings are correct for what ProCircuit has for jet sizes in my temp range. I believe it's running rich because of three reasons: Very smoky Very sooty (black drips spray out tailpipe) Engine revs very high when fuel runs out, until it's empty and shuts off. It also leaks fuel. So I'm wondering if these could be related. The idea is that because of the fuel leak, there is something (float or float needle worn) that is letting too much fuel in, causeing it to run rich. Then when the fuel runs out, it finally isn't running too rich and revs up because the idle screw was turned all the way up to compensate for the richness. I will check the float level and go from there. Does this sound like a possible fix?
