Two friends' KLR650s with the top L pattern cut out and the screen behind the air filter taken out... One engine blew because the nut that the air filter wingbolt screws into came off into the cylinder while running. The other bike had the air filter wingbolt nut come off when taking out the air filter for cleaning. But, it could be fished out cuz not running. I gather the air filter nut is normally glued or press fit into plastic behind the air filter. IS IT REALLY WORTH RISKING BLOWING YOUR ENGINE BY TAKING THAT SCREEN OUT TO GET THE PROBABLE 1/4 HORSEPOWER BOOST? Jeffrey nakedwaterskier@...

Not to mention that the screen is there in case of a backfire, to keep your filter from catching FIRE... But hey its your bike.... Just cannot see that screen (unless plugged) changing ANY amount of airflow that is measurable... If you wanted a bike that has more horsepower you should go buy a KTM and have all your body parts go numb from vibration, or the other 650's available. KLR = Tractor, set RPM and shift gears. Its a KLR... Simple and Easy. Dooden ( My Opinion ) A15 Green Ape

As far as I know Kawasaki is the only bike that uses that screen so is it really necessary. How do the other manufacturers get away of not having the screen? Has anyone ever had an experience of a backfire actually catching an air filter on fire? I think the answer to the problem you reported is to Loctite the nut that's coming loose.

Loctite has nothing to do with it. If you loctite the air filter screw into the air filter nut, you will never be able to change or clean your air filter again. If you loctite it you will not be able to turn the wing screw to take out your air filter. The air filter nut is press fit or epoxied into plastic. It obviously comes loose sometimes. Other bikes probably have the air filter nut secured better. THINK BEFORE YOU WRITE!

[Doug Pippin]

Thinking now. Obviously you don't know how Loctite works. Put some blue or purple Loctite on the threads and it will retain the threads and you'll be able to remove the screw whenever you want. Loctite is not a permanent thing it's an adhesive resin that hardens in the absence of air, as a replacement for less-reliable locking washers when securing bolts and screws. It does not permanently lock the fastener. It just secures it until you break the fastener loose. If you Loctite the screw and the nut comes out the nut will remain on the screw and will not be ingested into the engine. Not thinking now At 10:26 AM 11/26/2008, you wrote:

For those who don't know. Loctite and a lot of similar stuff comes in Red and Blue. The material, not the package, blue is removable with tools, red is deliberately a PITA to remove, it is mean to be permanent. I'm no expert on the chemistry, but be careful if you are colour-blind.

To go a step further wih the Locite, I believe the low strength stuff is 222, I've used it for years on bolts as smaller then 4-40 on electronic components that are subject to vibration. It has about the same release strength as a nylock nut. I think I was told by the Loctite rep that sme of their products could make certain plastics brittle but have never had an issue with it myself..have a great evening...Greg

For those who don't know. The air filter screw is inside the air filter box and it is very difficult to get much leverage on the air filter screw So, you will be sorry if you use blue or red Loctite on it. So, keep the screen in and don't use Loctite. It just create hassles. Jeffrey

Be careful and thrifty with the use of Loctite. I used the med strength blue Loctite on the bolts holding down the hood scoop on my race car. I apparently used too much on the bolts, and it bled to the paint on the hood, lifting the paint at every bolt. Further clarification is apparently needed on the TYPES of Loctite and uses. The Blue loctite is medium strength, the most common used, and is removeable. Works great. The RED loctite is for seriously permanent fasteners. The instructions say heat or extreme effort will be needed to remove. I think there is a green Loctite, and I think it wicks into already assembled fasteners, but don't quote me on that. Obviously, you would use the blue loctite on something like a air filter screw. Perhaps the Red loctite on something like an engine mount bolt. I have seen loctite used on plastic items, but keep in mind it may attack materials other than metal. Jeff A20 In a message dated 11/26/2008 5:08:16 P.M.
