I need jetting specs for 1974 ty250 with a VM24 carb

Hi all, I have a pair of TY250 mono forks model 38V, but the left fork leg doesn’t have a thread cut into it for the axle bolt, the plain hole is small enough diameter to tap a thread into. I’m just wondering why it wouldn’t have had the thread in it already?. Has anyone come across this before? thanks

Fitted a electronic ignition as instructuons say. Now ty will only start by putting a drip of petrol down bore. Good spark, new petrol, clean carb, reeds look ok. Timing is 2-3mm measured with strobe. Once running rev/ rides fine. Kicks back up ok. Only tried it for 10mins running Any ideas before i put old ignition on to prove a point, or is 200 majesty timed diffent to a ty175 Thanks

Hi, Is it possible to use 1975-1976 LH and RH crankcases from YZ125 with the all the components and covers of TY175?

Does anyone have any info on the dimensions of the TY125 majesty. Would one of these be useable by an adult.

Hi, The ball and the spring for the shift cam can be installed through the threaded hole when the cases are put together? or only when the cases are split? (the cases are currently split, and there actually no ball, just spring) Part number: 93505-16006 (#6 in the attached picture) thanks

What is my best option for alternative cylinder (barrel) for 1975 TY175 USA? DT175 or CT175? Or maybe something else? Thanks

Hi, All! Working on making my recently purchased 1974 TY250 rideable. I'm doing repairs from probably decades of neglect, abuse, and a bit of "Hillbilly Engineering" from the previous owner(s). At the same time, I'm making a few minor "upgrades"; like the Sammy Miller wide footpegs that lower and move the pegs slightly rearwards. This requires removal of the swingarm bolt. While that bolt is out, I thought I'd look into replacing the grease nipple and the pivot bushings. I got the swingarm bolt out after somewhat of an epic battle. Now I'd like to get the long inner bushing out; the one sorta shaped like a long dog bone that goes completely through the swing a…

Hey, All! I'm slowly getting work done on my project TY250A. I got the swingarm "repaired", sandblasted, primered and shot some rattle can enamel on it today. The old "bumps" on the the swingarm that the snail chain adjusters push off of were really worn with grooves somehow. Maybe someone (previous owner) let the rear axle get loose? I say this because there is also damage to the dust collar on the drive side of the sprocket and the inside of the swingarm itself. I dunno how it could've happened, but it did. I ground off the old bumps, and drilled and tapped for 6mm allen headed bolts for the adjusters to work from: Now, I'm working on my fiberglas…
