You'lll need to put .7 liters of oil on your bike. When you changed the filter, you'll need to add .8 liters of oil.

Hope this helps! i'd appreciate a rating!

It could be a loose shift index wheel or a weak index wheel spring. The index cam could be loose also. Another item to check is the shifter shaft and return spring. There could be a slightly bent shift fork causing the problem, but since you didn't mention having to force the shift pedal I doubt that is the cause. By the way, if a shift fork is bent, an engine tear down will be needed.

Can I get a “very helpful” rating on this answer?

The oil capacity is marked on engine side as well as gearbox side. On gearbox side there is a 8mm screw just before the clutch cover. Take this bolt out and fill until the oil start coming out this hole, should be about 600ml. Do not use full synthetic oil in gearbox, this does not work well with the clutch friction plates. On the engine side put about 500ml (depending if you changed the oil filter as well), then check level with diptstick by placing diptstick in hole WITHOUT SCREWING IT IN. Fill with little bits at a time until you reach the max mark on the diptstick. Start engine and warm up. Shut down and leave for 3 minutes. Check oil again. DO NOT overfill engine side.

check you water pump, could be clogged

Do you have the timing marks at Top Dead Center?

Well i currently ride a new 250 06 crf but the last time i had a knock was on my 2000 cr 250 and that was piston slap cuz the rings where shot..

Check your clutch pack first ( fingers crossed ) .
Have a good listen to the engine to isolate the area of the noise ( putting your ear on the handle of a long screwdriver and putting the blade of the screwdriver on your motor is a good trick).
The noise is most likely to be a broken needle roller bearing .

Try a small shot (about a 2 second spray) of starting fluid in the air intake then cranking....
WARNING- DO NOT TRY AND KEEP IT RUNNING BY USING THE STARTING FLUID! It can damage your engine.

If your bike fires and runs for a bit, the most likely problem is your gas has gone "sour". You need to drain all the old gas out and properly dispose of it.

Over time, gas will cause a varnish buildup in your carb if it sits too long. You can try adding some carb cleaner to fresh gas, but the results will not be immediate. You may have to have the carb rebuilt.

When you store anything gas powered, there is an additive called Sta-bil that will act as a gasoline preservative for about a year.

it could be a lack of oil getting to the valves and it might just be how hard the bike has been riden i have a 09 kx 250f and it makes the same noise but its done that ever scince ive ownd it did u buy it new or used?

Could be a bad head gasket, cracked head or cracked cylinder. You wont know which one for sure until you have it disassembled.

you need to remove the gas tank to get to the plug, remove the seat now the bolt to the gas tank and the bolts holding the plastics to the rad. there is a fuel petcock that bolts to the frame turn it to off and remove the lower gas line from the petcock. pull tank off and there is the plug. be careful with the valve cover and the socket you use it might get hung up.
Best of luck

57psi is fine if you are using the decomp lever when checking the psi. The normal psi without the lever is 120min to approx 200.

OK I can't give exact reading for Honda specific but I do do this test on Yamaha YZ WR etc all the time and your reading would be very simular if not the same
You should have a connector with 3 pairs of wires (6 wires) coming from the stator
You need a multi meter preferably with auto ranging OHMS reading or just set to OHMS (the upside down horse shoe setting)
you need to test each pair separately and starting with main out put pair (red and something colour wire) you will get 260 - 360 the next pair you would expect 700 - 1000 to show on meter reading and the third pair you would expect to see 40 - 70
Now these will not be perfect ranges for your honda but trust me if your stator is faulty then you will get way out numbers like 002 or 010 or 4000 all of which are completely out of spec on any of the 3 pairs so you will easily spot your stator is no good
cheers mate good luck

Is the remainder of the bolt still in the threads??? Get a good bolt extractor to remove it.
If the remainder has gone in the engine, if you can't get at it with a magnet (get it to the hole and thread it out) you will have to get the engine split.
