anyone know anything about old skool yamaha yz's? NOW WITH PICS
Bought a red one tonight at an auction for peanuts! Think it's seized as the kickstart won't budge at all! Looks like an early 80's one but the spark plug sits at the front of the engine facing the front wheel and it has a fill hole for oil??? Thought 50's just used the normal petrol/ 2 stroke oil mix?? I'l get pics up asap

PW 50,s are loads smaller than an 80.The 50 is auto and the 80 is three speed semi.My lad had a 2004 pw80 for about 3years.Absolutely mint bike,2 years old when he got it.Never had to do a tap to it except normal g/box oil changes.Far superior than the Chinese 4 stroke crap.You say its red ? all red or red seat,what colour are the plastics,white ?.When you can,stick some pics on.Some one will tell you what it is.

PW 80 you have there.If its white underneath its an older version.Makes no difference.These are great,bullet proof really.Take the exhaust off at the front to see if the restrictor is in there.Its only a washer and will just pull out with your fingers.You should know by riding it really.If it revs ok no restrictor,if it seems to struggle it may be still in.The perfect bike for any young un to learn on imo.My lad used to be on and off the seat flat out on his and I would be along side on my 250 or 450.He progressed to a RM65 after his pw.Dead easy for parts and to work on,there is nothing too them.Let me have a think and I will see if I can remember how i.d. the year .Compare your frame number with this one *4bc-094593*.
Ah too slow,I was trying to find that frame number.Cant remember what year they went blue.At least you sorted now

Get the head off then the left hand casing so you can get to the fly wheel ,lots of WD40 down the bore then rock the fly back and forth ,you may just have rings rusted to the bore .

If it wont turn over you may aswell take the head and barrel of(10 mins).What is it exhaust off and for nuts for the head.Be carefull these dont snap,if they do once you have the barrel removed you should be able to change the threaded bar pretty easy.Its just a matter of course removing it anyway for a new piston and maybe a rebore.Its all cheap as chips anyway.Give the crank a yank up and down whilst your there because if it has seized from lack of two stroke (is the autolube connected up,oil bottle under seat) the crank gets its lube from the fuel mixture so the bearings in that may be goosed.I will keep an eye on this thread
