Sounds like a lean condition. Spark plug should be a tan brown.
I would say the carb probably wasn't drained prior to storage and your main jet is gummed up. Gas deteriorates very quickly especially in vented containers like the float bowl of a carb.
clean your carb for sure.

Have a crf 230f honda how can i jump start it in middle of nowhere if battery dies

I am not sure why others are recommending a carburetor rebuild - that has nothing to do with "how to jump start a CRF230F..."

If riding with others (as you should ride with at least one other person), you can disconnect and remove the battery from their bike, connect it to yours, and use your electric start. This is, of course, if the other rider has a battery in their bike and you have a 10MM wrench to remove the side covers and and battery cables.

If alone, or other riders have bikes without batteries (2-stroke machines), do the following:
* Put the bike in 3rd gear (1st and 2nd gear are typically too low of a gear ratio for jump starting to successfully work. The rear wheel will simply lock up and slide.)
* With the clutch lever pulled in, start pushing the bike as fast as you can (it is easier to do this on part of the trail / road with a slight to moderate decline)
* With the bike rolling as fast as you can get it going, hop on the bike and then let the clutch lever out. With the rear drive wheel connected to the transmission/crankshaft/connecting rod and piston via the chain, the piston will compress the fuel/air mixture, the spark plug will ignite, and then the engine should fire up and be running.

How do i ajust my suzuki rm 80 carruetar

  • First locate the idle screw on bottom of carberator, It might be under a little 1/4" brass plug.
  • You will need to drill out plug to get to adjustment for smooth idle or correct mixture adjust.
  • Recommend pulling carb off of bike for this procedure
  • You should adjust idle jet first to about 2 1/2 turns out roughly then turn it in or out from there for highest rpm! Once that is done adjust idle speed with manual adjustment on left side of bike for smooth idle and about 900 rpms or so.
  • Basicly that is all there is too it. Unless you are installing a jet kit or something like that.
Good luck and happy riding... HDTV GURU JAY

My bike has been standing in the garage for a couple of months and it won't start. When I try and press the start button th engine does not make a sound is there a battery?

Hi there,

Yes there's a battery and chances are its already drained. recharge the battery (or have it recharged) and check for the spark plug as well. I recommend replacing it with a new one. Also drain the carb fuel before starting it to make sure any deposits don' t go straight to combustion.

A quick solution to this is to jump start it on 2nd or 3rd gear. Engage the gear, depress the clutch and run the bike for at least 15 meters until it gains momentum. Release clutch slowly while assisting the throttle. If it fails, try it with the choke on.

Hope this helps,
(please rate )

2007 Honda CRF 230-Not shifting out of 1st gear

I have a feeling you broke a yoke, That bike is fairly new, and I don't think the tranny is trashed yet, probably just something in there slipped off. I don't know how hard it is to get to the gearbox, but you have to go in there and find out. I couldn't find any complaints about it in the forums, supposed to be a nice bike. Hope this helps.

A clunck noise changing gear

This does sound like a gearbox problem, either where the cogs lock together (the dogs go into recesses) or the shift forks themselves
The dogs do wear after high mileage which can make them slip out of gear
Ive never heard of a gearbox smoothing out over such low mileage, but I suppose it is just possible
You could get the gearbox 'blueprinted' (i.e. to manufacturers exact specifications) but this will cost a bomb !
Your best bet is to complain again & at least get a ride on another rocket3, or get it sorted under warranty

Ride safe
Please mark this as very helpful (if it has been!!)

Bike sputtering & change of exhaust may nedd re-jetting??

generally when installing after market performance exhaust, jetting the carb is necessary. until you get ahold of the previous owner and find out if the carb has been jetted, you can try and adjust the fuel air mixture screw and see if that helps. and like any engine especially bikes, it is possible to sieze the piston. it can be riden, but be careful of over heating. hope this helps...
