    Hi, I have the same question about the chain.
    With the bike on the stand how many fingers should I be able to put between the chain and the swing arm. As far as i know it should be three fingers on stand, please help me out; you people seem to have more knowledge about dirt bikes. I am a sunday rider.
    P.S. Sorry if there is mistake on my English I am from Italy.

To adjust the chain you need to make sure you make the adjustment with the swing arm parallel to the ground, (this is the tightest point in the arc of the swing arm moving rotation), at that point you want to be able to put two finger between the chain and the swing arm at the swing arm pivot bolt. This will insure proper adjustment every time. The best thing to do is have somebody sti on the bike off the stand to make sure the swing arm is at its MAXIMUM arc, otherwise you stand a significant chance of over tightening it and this can and WILL cause SERIOUS damage to your engine. You will rip the output shaft bearings out of the center cases.
You also want too make sure you have proper wheel alignment as well. There are marks on the rear of the swing arm for adjusting the chain, make sure you have the marks on the adjusters in the same location on BOTH sides of the swing arm.
Please let me know if you need further assistance.
Regards,
RSelvy

My chain keeps coming loose


Properly tensioned new chains will require readjustment after a short 'break-in' period as they stretch. Some, improperly tensioned chains have long spots in them and they are difficult to properly adjust. All chains have a difficult life - even properly adjusted - properly lubricated - properly used (not abused). With a proper load (your weight) you should have about 3/4 inch play midway between the front and rear sprocket if your chain is properly adjusted. When properly adjusted and properly tightened, your chain should be checked weekly until you see no difference in the 3/4 inch. After that you should check the adjustment monthly throughout the life of the chain.

Need to tighten drive chain on a honda ca 125 but bike only has a side stand; does the rear wheel need to be in the air in order to adjust using the adjusting nuts?


No it doesn't need to be off the ground.

But, remember that when you are sitting on the bike and the suspension is compressed there is less slack in the chain, so don't tighten the chain too much. Tighten it until you have an inch and a half / 3-4cm of slack in the mid point of the chain between the front and rear sprockets.

Timing chain


If you can fix the Caddy I'm sure you can handle the Mitsu. Go to www.alldatadiy.com and buy a subscription for the Mitsu. All the info you need will be right in there. Or I can scan and email the timing chain replacement procedures to you.

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.
