Air leak

Recommended Posts

So I just replaced my base gasket on my cylinder. But it still sounds like I have an air leak! Could this possibly be from a messed up or bad head gasket? It only sounds like I have the leak when I ride her hard! Hopefully it's nothing to serious! I will post a video if needed.

You could do a leak down test (there is a sticky on this). Having said that, IMO the easiest way to find an air leak is to mix up some soapy water in a spray bottle, start your bike and spray it all over your motor where the gaskets are. You will see any air leaks that you may have. Of course, this doesn't work if it is one of your crank shaft seals that is leaking.

Look who it is, my buddy fdrbtr lol but Wow man i didn't even see the sticky up there, Sorry about that and thanks bro. Really helpful! And wouldn't be the crank seals, I did them when I replaced my crank and piston.

Check the air boot on your reed cage. They have a small lip that acts as a gasket. On older bikes the lip can become flat and let air in. And make sure you ALWAYS have a finger on the clutch. An air leak can cause your bike to take off at the most unexpected times.

Well using the soap water technique, I found the leak. I sprayed the base gasket line and the head gasket line on my left side. No leaks. I sprayed my right side and my power valve sucked the soap in. I took the cover off and peeled the gasket off. The gasket was beat up! Luckily I had an extra one lying around!! Thanks y'all

Hmm it was sucking in soap, so I figured that was it Seanmx57. Didn't know that couldn't be a problem area for air leaks. But since there is not any leaks coming from the gaskets or exhaust port, I'm gonna start with the Airboot like CR15 said! So how do I check the air boot, same soap method?

      Kicking around the idea of selling my CR250. I have other bikes and never get a chance to ride this one.

      This is a well-maintained bike with tons of aftermarket parts. It's set up primarily for woods/single-track riding, but will still do just fine on an MX track.

      Engine:
      -Fresh Pro-X top end(<1 hour)
      -FMF Gnarly pipe & FMF Shorty silencer(<1 hour on fresh packing)
      -PWK Air-Striker Carburetor(bought new from JD Jetting last year)
      -Steahy 10oz. Flywheel Weight
      -Boyesen Rad Valve with Carbon-fiber reeds
      -TwinAir air filter

      Misc:
      -Excel Pro-Series Wheels(19"/21")
      -Brand-new Shinko tires(546 Front, 505 Cheater Rear not mounted yet) w/ Heavy-duty tubes
      -Works Connection Radiator Guards
      -Skid Plate
      -FMF Factory 909 Handlebars
      -Polished Frame
      -Sunstar 13/51 Steel Sprockets(new in box)

      I'm sure I'm missing a few odds and ends. Comes with a Bill of Sale only. (708)287-1998 - Dave

      Hello,
      I could not seem to find a similar thread so if one exists I apologize. I have an 02 cr250r with an 01 motor. I need to buy a new silencer with a spark arrestor because the current one does not have one. I am not sure if the owner before me used an 01 or 02 silencer because I have read the frame had significant changes from 01 to 02. Any thoughts? Thanks!

      I want to restore a 1996 cr80 that doesn’t have any graphics and absolutely love the 1994 cr125r tank shroud graphics, I can’t seem to find anything that fits the cr80 with those graphics. I found one last week but lost the page and couldn’t track it down again, do the cr125r graphics fit the cr80 tank shrouds? or does anyone know where someone could make them for cheap or know about any in Australia

      Hey guys,
       
      Could someone please explain the numbers on a needle jet for a mikuni carb?  I'm currently running a 38-73 needle but a lot of the people I talk to say I would be happier running a 38-70 needle.  I don't have a problem with going with what other recommend but I would like to understand the numbering for the needles first.  I understand the nozzle sizes, main jet and pilot jet it's just this damn needle thingamobob
       
      Thanks a lot
