oil ok is that a question or a statement, first part is obvious check the oil, low? is there water in it ?  i/o inboard , or out board? if i/o or inboard check valve covers, for leaking if you haven't change it recently give that a shot, could also be oil pump is weak has it been run hard? basically it could be a lot of things start with low oil, then look for oil around valve covers, check for loose bolts on covers and beyond that if you aren't mechanically inclined your best bet is to take it to a tech

That means either the piston rings or cylinders is worn or the valve guide seals are bad. Since it is a 99 I would be looking at the piston rings or cylinders. This basically intails rebuilding the engine which will be costly. You may be better off adding oil treatment and 40W oil.

go to www.allfordmustangs.com go into the tech department and look it up. I think it is under induction or Engine. Not completely sure. Hope it works. Good Luck.

uh its hard to explain depending on the bike race bike or a trail bike? ive got a four stroke an XR450/get the speed that feels comforable to you in 2nd or 3rd gear rev it slightly/shift/pop the clutch/and lean back/while ridin it you'll have to keep ur balance and keep the throttle right, when ur ridin it its all in ur right hand w/ the gas thats the part thats hard to explain>>>

Try looking up repair manuals on e-bay.

Check on E-bay, they have a few similiar vintage models you could compare "going" prices on. Also if it runs and you are close, i'll buy it. I need a motor for my fishing boat.

westinghouse, General Electric,are the best motors to have,if you're replacing a motor take your old one to a distributor to match it up shaft and coupling.will it be a ran at intervals or 24 hours? be sure to check the amps to make sure it doesn't overseed what you're repacing.use the yellow pages in your phone book to locate a dealer near you...you can buy a cheaper motor like an appco but it won't give you the reliable service like Westinghouse or Ge brand make sure you buy one that's designed for your application and if it's going to be an inside motor or outside motor get a sealed bearing motor if you have a choice don't use a indoor motor outside wetness could cut the life of it short.Hoped this helped you some....

I have a 35 hp and it's 50:1 it should say underneath on the motor somewhere, Unless it's missing. I hope this helps otherwise just call a Johnson dealer and ask them.

Check eBay motors. They have a section dedicated to parts.

good carb  probly an 800cfm  the two screws in the front / bottem of the carb with springs. work slowly and at idial speed in 1/4 turns or 1/2 turns or one full turn.\n\nturn one screew in (tight) a 1/4 turn listen to the motor go another 1/4 turn lisen for a change do not ever rev the motor....wait be patient.... go another 1/4 never loose track of your starting point  whitch is 3/4 turn now\n\nwhen you hear a change in idial losen it a 1/4 wait some more\n\nnow do the other screew the same. I\n\nf the factory lock glue is still on the screews dont touch them\n\nand this will not save you gas

I dont know much about bikes, but it sounds like you probably need to oil it...

i had the same problem with my 91 lumina with a 3.1 multiport, one of the cylinders wasnt firing properly, so at about 45 mph she would really start shakin so i just drove around with it in a lower gear. might wanna check plugs,wires, power pack, and air filter, maybe even spray out throttle body.. if u have a schrader valve check fuel pressure while at it. could be exhaust related too if the cat is clogged.  just some ideas

If its rebuildable, I would recommend Jerry at Deadbolt www.boostplanet.com.

depends on the stroke of the engine, call a boat shop or one that works on outboards they'll know\n\nyou can really jack up an engine if you dont mix properly or do when you shouldnt\n\nask a professional

a turbo will blow ur motor, get a cold air intake its pretty cheap and it will give u about 10-20 more horse
