  1. no idea. It's a pain to do it too. I can only remember the number from one of my twinshocks. The rest I have to go looking with a torch. Maybe I should make a list. A friend of mine who also rides multiple bikes confessed last weekend that he just makes up the numbers each time "because no-one ever checks them anyway"

    Sorry for not being Guy, but all over the world people remove three of the clutch springs on TY250 twinshocks to lighten the action
  3. Frame and engine numbers on entry forms for trials competitions has been standard practice in Australia for as long as I can remember, but I don't think anything is done with the numbers

    Baffleless TY

    The body of the silencer is the same (250 vs 175) but the inlet pipes are different length and shape

    My WES end mufflers on TYs are quieter than stock too

    What Is A Twinshock ?

    Modern internals vs modern forks makes no difference, but fork visuals are important to me. As for the motor, there are potentially important advantages from using a later motor, such as less weight, less width and less length

    No Snap!

    The last video looks like how a standard Ty250BCDE in good condition responds. The standard motor has a strong flywheel effect that most people didin't like when they were new and the same sentiment applies even more nowadays with grippy tyres and good rear suspension. Lightening the flywheel is a very common mod to these engines. Another beneficial mod to make them more snappy is to fit a good modern ignition.

    How about a photo of what you are talking about

    Montesa 349 clutch fluid.

    Make or find a puller that doesn't damage the gear teeth. The usual two or three arm puller will likely not be able to pull hard enough and will damage the teeth. A suitable puller will pull against the back side of the gear without touching the teeth and it will pull on the whole surface, to spread the load better. I made a tubular puller that is in two halves. There are discussion threads on this forum that cover this job in detail. I can do photos again if the thread has disappeared.

    I will be interested to see if you still think it is easy to work on after you get the primary gear off
  11. you've probably sheared the flywheel timing key

    I saw the other side via some other photos which were posted on Facebook. I saved the photos and will post them up soon

    TLR200 running right?

    It's normal for a 4 stroke to have a strong on/off effect with the throttle

    My 348 used to have a positive pressure inside the clutch casing. I was never sure that it was a crank seal causing it though because I cleared out the gearbox vent (which was blocked) at the same time that I changed the crank seals.
