KX500. non sealing exhaust header pipe
barryadam:
And fix that leaky exhaust connection, will ya.
Remove and clean it really well, get some new o-rings and use plenty of high-temp silicone.
Come to think of it, I need to re-seal mine, too. My LHS Boot is getting a bit of coverage.

-50:1 i will try that cam thanks (geeze i hope your right hehehe :lol:) is that because its good oil or just the factory specs and where was this information for future reference? just in case I change oils.
Have never really had proper oil bought b4 as my last 2 stroke bike was back in the 90?s and it was an 86 KDX which I used lawnmower oil on hehehe what a tank. Since then I have sinned against all things 2 stroke and have had a husky 610 4 joke. this has made me a bit lazy I suppose. But I didn?t have to play with the jetting on the kdx, so all this is new to me.
Now guys im looking at the jetting chart. Please excuse my ignorance ive heard things like pilot, main, primary and slow jet, also I have heard of idle jets. Just getting a little confused at the moment
What are the only ones I need to worry about and does the names like main and primary mean the same? As do pilot jet and slowjet?
I know the air screw hehehe whoopeeeeee. Pretty sure the needle clip wont be to difficult(that?s on the slide?) just names of the jets. Once I have the understanding of what the names are and their locations I should be ok.(the jetting chart looks quite informative)
KXcam22:
Look on sudco.com. I think they have some elementary carb descriptions. Basically there are only a few things to check.
1. float level. Set it and forget it.
2. Main Jet - size controls mixture 3/4 throttle to wide open - this is the first one that you set.
3. Pilot Jet - size controls mixture zero to 1/4 throttle - controls starting, low speed running and plug fouling.
4. Needle clip location. - controls 1/4 to 3/4 throttle - all midrange stuff. (need to verify you have the stock needle just in case someone changed it)
5. air screw - set at 1.5 turns out and forget it.
See its easy. Cam.

thanks for the sites danger4u2. very informative :wink:
cheers cam thanks for your info that is exactly what i needed your a legend. 8-)
and you recommend 50:1 with that oil (or is that oil specs from oil manufacturer?)
also that jetting table, is that specific for his type of bike;
-reeds
-pipe
-oil
etc........
or is it just a guide for a ball park figure for temps and eleveations that can be used whatever parts you have on your bike?
