How many different questions are in this thread anyway? I lost track somewheres.
New threads are easy to start.........
Rich/lean bobbles are not that easy to recognize..thus Inda ended up where he did..richer. The age-old adage, 'If it goes BOOO-WWHHaaahhh' when you crack the throttle, it's too rich,' is usually an age-old error. The OEM needle on clip-2 has rarely worked well from any jetting posts from riders that went to the trouble of actually testing different clip positions.
Fact is, the OEM needle is so far 'wrong' in so many ways, you won't likely have a LOT of luck making it work as it should. ...which is why so many KDX riders don't USE the OEM needle no moh.
No lid makes more noise. Any lid modification will require some jetting change most likely. I never had any luck with the 'no lid' idea...couldn't abide the noise, anyway. Keeping the snorkle and putting some holes in the lid will keep it quiet AND improve lower-end response.
JohnM: I don't know what your friends are even trying to say...but 'new ones' sounds good to me.
If it's all good at 200', it's going to be too rich at 3500'. You say what your friends recommend, but don't say what you ARE doing. For starters, let's hear about quarts and not liters, OK? You're in Maryland fer crine out loud. Buy a ratio rite mixing cup!!
Putting a liter of oil in 4 gallons of fuel is more than 16:1 for heaven's sake!! That's too much oil for a chainsaw
!! fer heaven's sake, crin' out loud and I'm running out of amazement things to say!!
But then you say, 'mix oil with 5 gallons of gas.' I don't know if that's still a liter (arghh) you're talking about or not.
I'm going to go finish watching Ricky Bobby kick some butt..and pretend none'a this ever happened.....
THEN it'll be time for FOOTBALL...and I sure'as hell don't mean SOCCER
...all this talk about litres hath me frazz`led..........'eh vois even!
BTW...go to buykawasaki.com and look up the carb diagram. ..ronayers.com has one, too.
There you can see drawings of where stuff is...like pilot jets and such..which, btw summore are up inside the lttle hole just in front of the main jet. Take it out with a 1/16" common screwdriver. A 2mm blade will do.
