Sounds like this is the decompression lever area.. did you leave/forget something out?? This lever should have a cable connected to it... If you paid someone to do this... take it back!!

SOURCE: crf250r starting problem

try jetting the bike. the hondas come stock with horrible jetting which make them a bear to start, even compared to other high-performance 4 strokes.

You will have to clean the carburator, blow the jets with compressed air,check the float level too and reset.
Good luck.

SOURCE: My Honda crf250r has trouble starting.

you better check for valve clearance.....and to be honest you're intake valve maybe to tight and kept open.....you will reajust it but this will last a ride or two...because maybe the mobdelium coating is done on the intake valve and it is getting tight all the time and kept open....put two new oem valve from honda and you will be back on the track....sometimes i also never rectify any angle on the seat of the valve, just put new one and go.....honda as getting better since 2007....more good quality of coating on the valve....if you bought new valve for an older model they will come with that upgraded and last longer.

SOURCE: 2005 crf250r trans oil and funny noise

The water pump seal is maybe gone.This would allow water into the trans.Get it checked and also that the bearing hasn,t spun in its location.This may cause the color change.Being a grey color,it may indicate aluminium in the oil.This may be the spun bearing turning in the housing.With what you wrote,I would get these things looked at.I hope this helps you

SOURCE: Valve adjustment

Hi CX'er, This is getting basic, but in a 4 stroke engine there are 2 TDC spots . One being the completion of the exhaust stroke, and the second is the completion of the compression stroke . Give her one more turn and the valves will close . I hope that you are using the 17mm port under the radiator to turn the engine . It is the same as the port you are using to view the flywheel markings . Before I begin for the first time, I re-torque the heads . You must use a torque wrench, or risk breaking a bolt ! If you do it afterwards, your valve clearance settings will change . Accuracy is very important, check for tight drag, and check with next thinner for free clearance . Too tight can burn an exhaust valve . I set them to a tight drag, about .001 under, but I verify the clearance, twice . When you do the left side, don't forget to loosen the 10mm cam chain adjusting nut one turn (in front of the flywheel view port). Listen for the little click as the tension spring snaps in to take up the slack, and tighten, that's it . Make 'em purr, J

Starting problem with honda crf250r 09 model when cod or hot


I have a honda crf250 2009 model i recently brought it off a mate. Had the same problem could not get the thing started. Missed races cause of this... I worked out how to get it started. On Cold start, turn the fuel on give the throttle 3 full pumps. Then do not touch it! Put ur hand in the middle of the handlebars if need be. Kick start the bike still may take a couple kicks but on mine its generally about 2-4 kicks. Then through out the day when u want to start it do no twist that throttle it just squirts fuel in and u may as well just pack it up!! I know this is what i have to do not saying yours will be the same but i hope it all works out!!!

Torque specs for cam on 2006 honda crf250r


Rock the caps around to make sure the bearing locating clips are lined up. Torque the bearing caps to 12 foot-pounds. At this point you must check the valve clearances again. If any are off, the cam must be removed and the correct shims installed.

Please rate this solution. Thanks!
