Anyone else not install the air filter tight? Full rebuild now:)

Then it falls off in the air box, then you burn the bike down? Just wondering if I am the only one to do this? I bought a Loudmouth intake system, new ER 295 cylinder and head. (thanks Corndog) New crank and rod. During tear found that my water pump seal was leaking, so I ended up getting a new shaft seal and bearings. I was already running a 51 tooth rear sprocket, so I went a 15 tooth cs. New chain, and went with JD jetting kit with #8 slide.

Some pictures for you guys.

New 295 kit




Motor out




The crank and cylinder and head were all ok, cylinder needs to be honed out but in great shape. I figured replace it all now and not mess with it again later. Got the cases split


At some point in this bikes life it had a major explosion lol.


Brand new OEM fuel tank. With New graphics.



Im putting it together soon so I will update the post with any problems.:)

bad luck there buddy. Im excited to hear about ur 295, what was it ported for with what fuel type? everyone in the offroad world loves them. Im more interested in being competetive at the track against 450s. keep us posted and thanks for sharing.

thanks for sharing

So what happened? Ran very lean once the filter fell off?

Yea went lean and squeaked the piston.

I am using the low to mid port.

I'm keen to hear what you think of the low-mid EG porting in a 295 kit. I thinking of going for the same thing. Seeking good low end for technical trails and hill climbs, but I also want enough width to the power so that with the right final gearing I'm not shifting too much on MX tracks.

How does one install the filter wrong? Upside down? The threads that hold the filter bolt on all my bikes are gunked up with filter oil, acting as a thread locker :smirk:

Kgmx, I agree, the filter bolt thread feels like it has permanent locitie on it, and actually gets too stiff after a while and needs a clean.

I think it's pretty common for people to do up the air filter bolt too tight. which achieves nothing except for gradual deformation of the filter cage, when then lifts on some points and does not seal correctly.

Over the years on my bikes, I've been real careful to ensure the filter goes on right, then I've always nipped it up lightly, and every single time I have to literally peel the filter foam base lips off the airbox. So I've never understood the need for greasing the base either.

Mine fell off one time. I could tell right away as the leanness made it start bogging out of corners. Luckily it happened with only a few more corners left in the last moto of the day so no harm.

      Hey guys, 
      I've used this forum as a "guest" for awhile now and I thought I'd share my build now that it's all coming together.  The primary purpose of this project is to help me train for roadracing my 2009 R1 at lower speeds as well as giving me a cheap alternative to racing the big bike. 
      Here's what she looked like when I picked it up from a local shop.  Paid $800 cash for the bike as you see it with 17' rims, FMF pipe, EBC 250mm front rotor and clip on handle bars.

      Fits PERFECT!

      Shake down run at the Herrin Compound last summer:

      As she sits today:

      i bought my yz125 from a dealer and they said that the clutch was broken so i bought it and it worked fine it would run move and everything and then it started to act up and now only first gear works barely though. when you put it in first it acts like its bogging down but its not and when you go into gears 2-5 it wont move i dont know whats wrong with it im assuming the clutch is slipping or something if you know please leave me a comment

      Hey guys, I have a 2003 cr125 I bought a couple weeks ago and I'm having a problem with it. The spark plugs die every about 15 minutes, with hotter plugs it will last about 45 minutes. I herd that if the timing is off it can over heat the plugs and burn out the the resistor. Is there any truth to that? The reason I thinks it's not fouling is because when the plug dies it gives no spark no matter how much you clean it, And it shorts out.

      Hi all, First post here. I need some help.
      Ive just bought an 05 yz 125 for a good price but it needs some work. One of the forks has some pretty severe pitting of the chrome on the stanchion towards the bottom near the brake caliper mount.
      Ive found a pair of good condition forks from an 04 yz250 for a very good price, from the research ive done its seems that both the 04 & 05 forks are 48mm but are different, with the 05 fork regarded as being better than the 04, but not as good as the 06 + sss forks.
      Im looking for the cheapest way to get me riding, Will I be able to make the 04 forks work with my 05 triple clamps, brakes, wheel, axle, spacers etc? If not does anyone know what hardware id need to make it work?
      Finally, as a last resort, does anyone know if i could swap the stanchion from the 04 fork into my 05 forks?
      Thanks, Andrew

      I bought a 2006 YZ250, have ridden it 5 times.  It needs some tuning, but I am not sure I'm keeping it so don't want to spend much on it.
      Has fmf gnarly expansion chamber and turbine core silencer.
      I ride about 1000 feet above sea level.
      I'm going to clean the carb and check the jetting.  What is a good jetting for me?  85 main jet?
      Also check the reeds.  Is there a big difference between getting aftermarket reed cage and reeds or just getting a cheap aftermarket set of reeds that fit the stock cage ie.  Boyesen Power Reeds?
      The other things I'm going to do is permatex all the joints in the exhaust system and a compression test.   It was 220psi 5 rides ago so I'm guessing itll be fine.  Its bogging a bit but I'm thinking its carb and definitely exhaust joint related.  
      Let me know if I'm overlooking anything that could make the bike run crisper and more bottom end without throwing much money on parts
