read all of the 18 pages of this thread and you should find everything you need to know on klx's even the mod on the plug/gap spacer  you make for the tacho drive to stop the wear on the cam journals in the head as kl's shared the same head as the klx

Derek
What length shocks do you have on your bike??
Regards
David

Hey guys figured I'd share my klx and get some insight. I upgraded to a vm34 and the change is amazing. Pulls wheelies easily. the throttle response and acceleration is awesome. My problem is cold starts. It takes forever to start it cold. It floods with choke EVERYTIME then I have to let it sit and start it with the throttle cracked. Main jet is 230 pilot 25 needle is at the leanest point.

Dave's not here man

Hoping someone can point me towards a solution to my cold starting problem with my KLX 250.

The bike is completely standard. 

I have to kick it for 10 minutes to gradually get it to fire and run, progressively more and longer till it runs and idles.

I found some Start Ya Bastard down the plug hole helps but it is still a bastard.

Once its warm/hot, it starts virtually first time every time.

Thanks

Pete

Id go carb problem. does your choke operate? pilot jet clear? richer pilot? try another carb? get your carb dipped in caustic cleaner?

sounds like it is very lean on the starting circuit. as above big clean out, blow all the circuits out with comp air, check the jets arnt cemented up with crud, especially the pilot jet. should sort things out. check air filter is clean, good knick and well oiled. spark plug newish?? spark plug cap ok? muffler not blocked by wasps?? float level right? fuel flowing down you fuel line ok? tank breather not blocked??

Guys thanks very much for the info. I was worried it might be something worse.

For future reference for someone having a similar problem .I bought it off a neighbour who rebuilt the top end about 18mths ago and hasn't started it much since.

Got new rings, valves etc to spec. by him.

I put new plug, cleaned and re oiled the new filter, put new oil and filter in, new 98 fuel and Pea Beau-ed the wasps before I kicked the crap out of it ;D and used half a can of startyabastard.

Keen to check the stuff you suggested and sort it. Thanks again.

Pete

Klx's start much much easier if you follow the standard big single drill, just ease the piston just past TDC let the kicker swing back up and then kick. Because that's rarely needed when hot it's not obvious that that is what's needed cold. Would be easier with a compression release lever but.. Mines a pig from cold if I don't do that.

old ign's are also an issue, maybe try a different box top coil etc. see if that helps. get a multi onto the main coils and see if they are in spec. just cos there is a spark doesn't mean there is one in the hole
