Hey!

Nice to hear that everything went fine!

I am thinking about getting the larger snorkel myself tomorrow, and duct tape the holes, as I should probably get the correct amount of air that way, instead of speculating around as I am doing right now with holes (I still have the feeling that my machine is running rich).

If I'll get the larger snorkel, using the DNA air filter, and the ER-5 exhaust, I might actually get one size larger main jet too (115, main jets are darn cheap (2$ a piece) anyway, so feels stupid to be greedy about them (and the snorkel is not that expensive, either)), as the ER-5 exhaust is "flowing" more, and the DNA filter itself also helps.

What are your opinions about this?

Hi

Yep, I think it is worth a try.

As you say the old spec KLE's ran a little on the rich side so I guess a liitle more air/flow will not hurt.

BTW, Do you have the ER-5 headers as well. If so how does the ER-5 header pipe fit under the KLE sump plate. (pics) I still have the original headers with a custom made slip-on tail piece. Will send a pic later.

I have also decided to remove the "clean air system". The vaccuum switch, pipes etc. The early model KLE's did not have this. I have ordered the OEM blanking plates and gaskets. I dont see the point of this gimmick as it seems like extra maintenance.

How do you think this will affect anything (performance etc.)? Any thoughts?

Hey!

OK, I have bought the 115 main jets today, but of course, the snorkel have to be ordered from Kawasaki, so I'll get it in 1-2 weeks!

That darn snorkel costs around 20$ (actually, I more or less were expecting something similar), but now I'll get it!

I'll give you more details when I'll get the snorkel!



Ohh, about the ER-5 exhaust. I removed the sump plate (if you mean that metal "plate", under the exhaust) for it to fit, but other than that, it worked fine! (had to make a custom "exhaust holder", but it fits well onto the cylinders, so you just need something to hold it there!).

I'll take a picture of the headers later (today or tomorrow), but for the record, they are equal length, but I understand that a picture might still be of interest!

To tell you the truth, not sure what this "clean air system" is, so if you could shed a light to this, I would be thankful

Hi

Apparently the "clean air system" takes air from the air from the air box and injects it into the two exhaust ports. Someone can correct me on this.

Hey!

OK, here are the images, though the quality is not that great (specially the second image, but I think you can see what it should be), as they are taken by a crappy mobile phone, but I think these will do!
(perhaps I should have changed "light mode" on the camera, but nevermind, here they are :P)

edit: I also found this picture of the ER-5 exhaust, so I thought that I could include it here as well!

Hi

I notice the main jet options on the old carb set-up (N96J needle) is #108, #110, #112, #115 and #118.

Hey!

Yes, those are "optional" main jets, that should work too, but using a 108 or 118 main jet for an old KLE 500, and not modify it, will probably make it go lean(108) or rich (118). Can't say this for sure, but I know that one size in main jet can do a noticeable difference!

If, for some reason, the 115 main jet will be too big for the new snorkel (as in it still is going rich), I'll just add some more holes in the back, but it will probably run just fine

Hi
What revs does the bike pull too until the power tails off?

Hey, ShaunJ!

If you look at the page before this one, you will notice on the graphs that after 8000 RPMs, the power will dramatically decrease, if you are using the stock exhaust and/or aftermarket exhaust with the unequal headers.

Using an other exhaust with equal headers will let it rev a bit more, until the power falls dramatically (8500 is the peak for the graph with changed exhaust, and as you can see, the power doesn't decrease drastically, but after 10.500 RPM, it will skydive down (well, you should never let the KLE rev past 10.000 RPMs anyway, unless you like to do an engine rebuild, which I doubt you want ).

But if you are using stock exhaust, there's no need to rev it past 8000rpm!
