SOURCE: fuel mix

use decent two-stroke oil at 50 to 1. don't ever buy oil from a gas station without sealed container; who knows what the oil really is

SOURCE: Hot starter

4 stroke engines require a leaner than normal fuel/air mixture to start when hot. The cold start choke allows more fuel into the mix. The hot start choke allows more air into the mix.

SOURCE: My RM 250 won't spark. The engines been taken

Things to check are

1/ Short out plug wire to good earth to check for spark, if none check rest of sequence. If spark, replace spark plug.
2/ Next check wiring connectors from the ingition module to coil and ensure they are all tight.
3/ This is quite technical but the use of a digital / analogue meter is required.
4/ Place a meter on each wire to the coil and crank (Without spark plug in) there should be some voltage / current flow through the feed wires (Not the earth - Black) If nothing trace back to Generator.
5/ Forgot to mention the kill switch operation, if unsure bridge these wires together.
Other than that the other tests involve sound electrical knowledge and is beyond the scope of the average person.
A thought, if this model has a battery ensure its fully charged.

Did you buy this bike from a dealer if so, I would take the bike back to them and state the problem. Ask them if there is a recall notice for this. Also inform them that it needs to be repaired under warranty as you've already had an accident while riding it.

Hard to start

fresh fuel, drain old out of system, clean air filter and fuel filter clean spark plugs and kill switch(use electric contact cleaner on switch.)if still hard to kick start clean the carbs out.if trash or water is in the system the jets and needle valves are probably dirty as well.

2006 rmz250 When I torgue the cam bearing

Are you CERTAIN the two cams have not been switched? Chances are there will be the letter "E" on the side of the exhaust cam gear and/or an "I" on the intake cam. The diagram below is for a WR250. I don't have a manual for an rmz250. Your cams are probably the same. Note that the caps should tighten to only 7.2 Ft lbs. (10nm / 1.0 m-kg ). Many other things could be wrong. Was the cam assembly removed incorrectly? Doing it incorrectly can damage the cam, cam caps and cylinder head. Is the cam runout out of specifications ( .0012 )? Are you using a standard torque pattern? ( Cris-cross from inside to outside ) for installing. The reverse when dis-assembling. It may be best to let the shop figure out the problem and do the repair on this one.

My 04 rmz250 is overheating. It started smoking 3 different times when i took it out the other day. Id let it cool down for a few, continue riding and about 20 minutes later it would start smoking again....

Several things here. Do an oil change, 10w40 motor oil. Run premium gas and install a new NGK spark plug one heat range colder than stock. It sounds like you have an air leak causing a lean fuel mix. Check the carb mount bolts and the intake manifold bolts for tightness. Also set the valve clearances with a cold engine > .002 intake and .003 exhaust. Check for any cylinder head leaks. This would show up as oil on the cooling fins at the base of the cylinder head. Tighten the head bolts if needed.

Hi and welcome to FixYa,

An RMZ250 has no mechanical adjustment for the valves, they are shimmed. Best approach would be to consult the Service Manual. Engines used in the RMZ are identical to the KX series

Pls post back result(s). Good luck and Thank you for using FixYa.
