I have a '95 kdx 200 and just took my carb apart after 13 years while putting new 607 reeds in. Bike seemed a little "flat" on the top end so decided to check on the jetting... To my surprise the main is a 145, the pilot is a 42 and the needle is an R1173L. Bike has a pro circuit pipe and silencer and Im about sea level. I am the second owner so who knows what happened before I bought it! Any suggestions would be appreciated! Thanks

check this if you haven't already.

Probably pretty close for TX. Do a compression check, along with following the above guide to get a plug chop done on your main.

Thanks guys, will do the plug chop.... Just can't believe there's a 145 main in there when the stock is supposed to be 160, unless I'm missing something.

they are jetted fat rich from factory

HOLY PROPER JETTING!!! Thanks to INDAWOODS and the informative "how to jet" I have a totally new bike. After a few plug chops, decided on a 160 main/42 pilot and WOW the front tire rarely touches the ground, very reminiscent of the KX500 I had back in the day.... Now back to my fork conversion!

160 seems still a little fat, have u tied 1 size lower?
I'm in okc and I have a 155 and I think it's till too fat... (i do have the rb carb and head though...)

this bike is amazing isn't it?

I'm actually in Phoenix and yes went up from 145, 152, 155 and stopped at 160 after I got the shock of my life! Bike literally increased in power by 40%.... didn't realize until I bought a KX125 to rob the forks from how much of a dog my bike was! I'm back in love with it now and can continue on with my fork conversion and of course sell that pesky 125!!

Awesome!
