Loss of power and motor noise

My '92 CBR900RR motor has 26000 miles and no leaks yet sounds like is compleetly empty of oil. Last run on freeway reached 95mph and would start dieing out but had fuel. Just does not run like a 900 more like a cb550. Have replaced rigrec, computer, throtle cables, coils. Heard it is a california motor with a restricted cam and once had emission controlls on it but the charcol can and other smog equip. were gone when i got it. I was considering a motor swap. Dont know what to do to make run like it should. If any ideas or suggestions i would be grateful and more than willing to take advice. Thank you

SOURCE: honda CB 250 1998-will not start, just clicking, battery is ok

Hi, Your problem lies with the starter solenoid, although you maybe using a fully charged battery to jump it, it appears to be sticking or possibly faulty due to trying to start with poor battery.
The starter solenoid is usually located on or near the Battery compartment, it is cylindrical and has two heavy wires attached to it 1 goes to the starter motor the other to the battery. If you are carefull you can by pass the solenoid by touching the heavy wire going to the starter motor with the jumper lead. Make sure the jump battery is connected and both the NEGATIVE leads are well secure. Put the NEGATIVE lead from jump cable direct to a engine mount bolt or engine itself Not the battery.
There you are FixYa'd

SOURCE: white smoke both pipes when started minute later gone away

White smoke indicates water in the combustion chamber. If the bike is still running okay I would keep an eye on the coolant level, make sure you're not losing any. Best guess is a blown headgasket. You can do a leakdown test or a compression test to check. If your headgasket is blown, two adjacent cylinders should show lower compression since pressure will be leaking from one to the other.

That's the kind of thing that probably won't run for long. Be sure and keep an eye on your oil level too, if you happen to be leaking coolant into the oil you can dilute the oil to the point it no longer lubricates very well.

Oil in ovverflo of coolant but not the reverse drive everyday flush once month

If there is oil in water, then there may be a head gasket leak. However, half a quart of oil loss every 15,000 mi. is not bad. If van runs perfectly, then I wouldn't worry too much about it. Maybe try some Bar's Leaks Head Gasket Repair for $30 or so to fix the slow leak in the coolant system.

No if the oil light has flickered you have oil pressure loss some time just belive the sensor do help us out. lifter do not cause oil pressure loss pressure is built in the rotation of the crankshaft. The knock under the plenum will point you to that cylinder that is affected, (main bearing) as for a 1995 the injectors can only cause a misfire but no knocking noise,will they honor the warranty

Oil light goes on...had a dry stick 4 1/2 qts put in. no oil on ground. after oil change light went on at 70 miles.. on 15 secs then off for 5 miles then on again 15 secs--- off 4 miles--off 3 miles- off 2...

if it's not going onto the ground, and it's not being burned, check the positive crankcase ventilation and the exhaust gas recirculation valves for oil seepage...also check your air filter, if its got oil on it replace the pcv valve.

Lost engine oil: 2002 Ford F150 Supercrew 4x4 5.4l engine

This is certainly one of the strangest things I have ever heard as a mechanic. . This almost sounds like some one is playing a game of letting your oil out this vehicle. With no visible leaks no burning smell of oil. However I would recommend that you check the coolant in the radiator and see if the oil is in the coolant. (If they are mixing together) If they are mixing the coolant should have a milky look to it, creamish white. If its good then the only other logical explanation is that the vehicle i s burning alot of oil, but if that was true you would see a grayish blue smoke from tail pipe. If you are 100% sure they are no oil leaks on this vehicle, then this problem is surely strange. Check coolant and get back to me. Good Luck

that could be the rack and pinion leaking. as far as the noise goes, it is more than likely the same thing. have your local mechanic check it out because if its the power steering pump its cheaper to fix that than it will be to have the rack replaced.
