    Anybody know this air filter?

    Thank you reubenswinks - I will try it out. I just got the bike back together minus the clutch cable. I busted the clutch mounting stay on the case being over zealous with routing the cable. I'll be looking for a competent aluminum welder next. It's going to be a great desert bike!

    KX 500 case welding advice

    Here is a photo of the crack
  3. I got over zealous stuffing a new clutch cable into the stay housing and cracked the mount. I was taping it with a screwdriver and hammer to slide in. It is now cracked but still in one piece. This is stay is aluminum right? Any good welder with experience welding aluminum can fuse this back together I assume. I wonder how many other may have encounter this. Thanks William

    Anybody know this air filter?

    Frankenstien bike! Well I think I have narrowed it down to a KX 250 filer. Twinair's website gives different part numbers between 1999-2001 and 2002-2008 151115 - Air Filter Kawasaki KX 250 1997 - 2001 151116 - Air FilterKawasaki KX 250 2002 - 2008 Can any of you help me narrow down which filter is based on the cage. I think I'm on the right track - thx

    JR 50 is making me insane

    I have spent soooo many hours trying to get this little guy going. When purchased it ran fine. Over time the bike would no longer move with a person on it. I have adjusted the clutch to no end. Tonight I installed a new set of friction plates, steel plates and large springs. Dealer forgot to order the there tiny springs and the central steel plate. Two frictions, two other steels and the three larger springs were replaced. I have spent the last hour and half adjusting the runout of the clutch (threaded plunger with the locknut) with no luck. I have run it in to the point where it stalls the bike once placed in gear and then backed it out to the point where it does not but it still wont move a person. The bike will lurch forward in gear but not with any weight on the bike. I have searched all over the web to no avail. I have had many many bikes in my life and this little guy is the biggest PIA to date. Thanks for any insight

    Anybody know this air filter?

    Pretty sure the airbox is from an 07 450f. Boot and cage are from something different. Boot has KZ3T stamped on it. I can see where the boot was altered to fit onto the factory 450f box.
  7. Hi All - I've got a little problem identifying an air filter. I have purchased two new filters trying to get it right with no luck. Below are a few photos of the filter and box. The bike is frankenstine of sorts and the gentlemen who built it sadly died in a boating accident before the bike was finished so I cannot ask him. I do know the Frame is a 07 KX450f and the engine is an 98 KX500. Airfiter and box do not appear to be off either for those two bikes. Have a look and thanks in advance

    Handlebar clamp stripped

    I'm installing new parts on my 07 450f and have run into some troubles. I purchased new cone rubbers for the handlebar clamps (post into the triple clamp) and the nut became quite tough to turn and then presto it became easy. I have likely stripped the nut and now cannot back it out. I do not want to cut the stud and wonder if anyone else has encounter this?

    500 engine/trans weight

    Anyone by chance know what a 2000 500 engine/trans weighs? I ask because I have a 2007 450f with a 500 2 stroke mated in it. I am setting up the suspension and wonder if the difference in engine weight is significant.

    Weight of 450f engine/trans

    Race harness 4T

    Anyone installed a race harness on a 4T? I currently have the harness and before diving in I want to see if there are any tips and tricks someone can offer. Also my RR is street legal (so very cool) and if I ever want to revert how hard would it be? I imagine removing the seat and tank and laying the wires and making the connections is all that is required - but then again optimism often ends in frustration.... Thanks in advance

    2007 450 suspension tuner advice

    Come on guys - really. I can post some nude picture of my neighbor - I'm just kidding Anyone with some helpful advice? I'm probably going to use Race Tech or similar but I do know certain bikes (years) have preferred tuners.

    2007 450 suspension tuner advice

    I recently purchased a 2007 Kx450f with a 500 mated to the frame. The previous owner built this AF bike and never rode it do to a sad story. Bike has sat for 7 years with a new engine, wheels etc.. It was recently put back together and offered for sale. I often send my suspension off and wonder who is best known for this year and model forks/shock? Mostly national hare and hound riding (lots of whoops) and a few hill climbs are in the bikes future. Thanks in advance

    Kreft vs Beta factory

    Bike now has 7 hours on it. Beta installed a Race Tech gold valve - thanks for the correction. I don't regret having Beta setup the suspension. The price was semi reasonable and I got a great shock with the setup. I could lean on them to change settings but I think it will be easier and less time consuming going another route. They had their shot and I don't get the impression that the service is set up this way. I have messed with the fork settings quite a bit including changing fluid settings. I would not want to remove any more fluid as the forks are now prone to bottoming. Initially prior to fluid removal I backed the compression out all the way and the forks still were not as compliant as I would have liked. I race desert and initially bought this bike for a baja trip due to it being street legal and unable to take a 2t due to fuel stops. Never planned to race the bike but I am starting to like it and may try a few rounds with this instead of my 2t. After all I have been passed by factory Beta riders in National Hare and Hound races as if I was standing still so know the bike is capable of being desert raced. Over whoops this bike currently is less composed as I am use to and is choppy and doesn't always track straight. Damping is off and leans towards the bottom of the stroke. I do have the next heaver set of springs installed and weigh 195 with gear.

    Beta Steering lock cover install

    BoogieMan - thank you. Worked like a charm. Why would you take this out? See the photo. This bike is a 2017 with 7hrs, two washes in the driveway and one rain filled day of riding.
