    Sr125 top end refurb

    in Yamaha Workshop

    Posted

    I wouldn't really be happy with that myself,,,,,, as you say its a full half link out.

    Din you try rotating the pully a few times then put chain on, or leave the pully half link short then by the time the chain goes on the lines might match up. You may have to rotate the bottom pully a few times if possible then realine everything and try chain again.

    Ya might need a new chain to sort it.

    Hope ya get it sorted

    1994 dtr125 winter project

    No no no, all metal parts have to be stripped bare and painted /powder coated, ive two engines to strip and rebuild one from them, I need to fit a power valve controller that seams not to be there lol, rewire the bike and come up with the cheapest way to supermoto it, as no big spend on this, this projects on a tight budget or the missus will rip me apart lol.

    Although these bikes had power valves fitted,,,,,,, Yam didn't make them operational untill the year 97. In 99 they got more up-dates, like a newer oil pump, generator, CDI ect ect

    So your 94 model never had a servo motor or pully for the P.Valve

    Best of luck with the restoration and keep at it till its finished......... (like i can talk)

    Carb settings for a 96 bike with flat sided carb

    main jet = 210,,,,,,,,, you have a dep so try 220

    pilot jet = 22.5,,,,,,,,, leave this alone

    needle clip position = 4th grove from the top

    air screw turn outs = 1.5 from seated (screwed in)

    float height = 20 - 21mm,,,,,,,,, no exceptions

    there is also a power jet,,,,,,,,, it doesnt look like a jet and cant be taken out. its a hole in the float boal,,,,,has a plastic pipe that goes up to top of carb and onto a spigot,,,,,,,, clean this out

    there is also a filter in the carb where the fuel supply enters the carb.

    start at these settings and go from there,,,,,,,,, every time you adjust something you have to give the bike time to react to what you did.

    You said in last post "

    Does any one know how to get the jet the throttle needle goes in to as I want to change that as last needle was a little bit bent so may have damaged it but I can no work out how to get it out?

    SO,,,,,, did you really clean the carb ?

    Is the snorkel on inside the air box,,,if not put it on.

    Is the air filter new or at least good and is the rubber ok and sealing on the face of the air box cover.

    My bike will red-line if I want it too,,,,,but if I take off the snorkel or in anyway give the bike more air the bike will bog just past half throttle

    You say you have changed the clocks,,,,,,,, you need to make sure the reed switch inside the clocks is take out (not cut) and taped up, then put clocks back togeather

    I think your carb settings aren't right yet,,,,,, is this a flat sided carb ?

    2 stroke pump

    in Yamaha Workshop

    Update

    I've got a copy of the DT125RE 2005 Yamaha manual and it say's "The adjusting marks a and b has to match when the throttle cable free play ends"

    The mark "a" is the scribed line on the end of the oil hose union and the mark "b" is the "O" line on the pulley. Looking at your photo the two marks are nearly lined up maybe a bit over on the pulley so when you remove the freeplay from the throttle the two marks should line up.

    Just another thought if it's getting through a lot of two stroke oil it maybe leaking through the oil pump seal in the RH case into the gearbox oil. Can you check to see if the gearbox oil has risen ?

    Tony

    This is the correct way of setting up the pump.

    Its just a bit fiddly to get it right

    Roughly 4 tanks of fuel to 1 ltr of oil,,,, sounds about right

    Yz125 problem

    in Yamaha Workshop

    Posted

    Hello first post here thanks in advance for all the help. I have a 2000 yz125 and after about 10min of riding it will bog and die no matter how much kicking you do it still won't start you have to wait hours and it will start and ride perfect for another 10min. Supposedly a new piston 3 weeks ago and has a full doma racing pipe.

    Is it getting enough fuel.

    Does it have a spark after it dies.

    Is it overheating

    Is it easy to start when cold.

    Have you good compression,,,,,,(supposedly new piston)
