Hey, i got a 2003 kx 125, runs great, starts first kick, fresh top end, lots of new parts, just doesnt seem to have enough power. what would make it not have much power, more in midrange than anything.

check and make sure choke is opening all the way,if it is only opening part way could explain why you don't need to use choke at all to start and then at higher rpm's it is not getting enough air causing it to basically choke it self out.
it runs but sputters. that can be 2 things. First idd your sparkplug cap has had it (get a new 1 from the parts store) 2nd it could be that your getting to much fuel in top end of your revband. easy to check just run your bike a few min with a new sparkplug and look at the color. Wite is not enough fuel. Brown is perfect mix. black is to much oil and if black and wet its to much fuel. try this test and maybe you'll find it
Hey Fata.... PLEASE take the carb(or the whole bike) to a QUALIFIED PROFESSIONAL... it will save you time and effort..carb work is NOT for amateurs..there is A LOT more to tuning/cleaning/setting a carb than a screw or two..
Well - not knowing the condition of the bike it could be a lot of things. I would start with a fresh spark plug, fresh fuel and a clean air filter. You say you already did the carb, reeds and top end - good. I assume you set the float level correctly. Did you pull out the petc0ck from the fuel tank - theres a filter that might be plugged up. Check your exhaust system for plugs - I've seen mice nest in pipes over the winter. If all this fails, look into your power valve system to ensure it's working and adjusted properly. If so, then do a leak down test - you might have a lower end leak. That's the best I can do without seeing or hearing it run. Hope this helped!
now then, i have a kickstart, i bought it for my kx 125 1999 but it doesnt fit it you send me the dimentions of the bolt it fits on to and the one i have will fit ill sell you it
