Bought 2004 Kawasaki klx 125 and takes 20-30 kicks to start with choke on and even more when cold. Won't run right until motor warms up n takes a while for it to warm up. Runs fine after it does but it's hard to get started. Any suggestions??

Well - usually something like this would make me suspect the compression and timing first then the jetting in the carb. You might want to do a quick compression check although I do not know what the pressure should be for your bike. I would suspect at least 165PSI. You could have bought a bike that was run without an air filter or something like that.

I would also check the simple stuff - clean the air filter, drain the float bowl and tank and replace with fresh fuel (especially if your fuel is diluted with Ethenol !) and maybe even replace the spark plug.

If all this checks out OK and you still have the same thing going on, you might need to alter the low speed jetting (pilot jet).
