  1. cater section difficulty to the competitors that routinely finish in the middle of the class. This will give them a decent challenge and keep it fun. Those at the bottom of the class will have something to practice for but not so difficult as to scare them away. Those at the top of the class would soon find it too easy and would consider moving up a class.

    Personal opinion is that "gate trial format" would be good for a fun day out. But Observed Motorcycle Trials is about riders competing on the same course with the same obstacles that must be ridden in the same order, and the better skilled rider will win.

  2. That would be the ideal but you'd lose the bottom end as a pump. Well, you'd get lots of oil being pumped into the cylinder through the transfer ports. As far as I know marine 2 stroke deisels do it by blowing the charge into the cylinder so crankcase compression isn't needed.

    No transfer ports. All oil stays in bottom end and transmission like a 4 stroke. Basically just mix fuel and air in the compression chamber. All that would be there is the intake port direct to cylinder from carb and exhaust port.

    Hold on, I may have found a flaw in that theory. As the piston goes up the cylinder does the piston completely block off the exhaust port. If not then there would be a "hole" directly to the bottom end where the oil is and it would all go into the exhaust pipe. But if piston seals the exhaust port this should work.

    Somebody let me know if this makes sense or if I have had too many :beer: I can tear down an engine, replace what is broke and put it back together..........but some of the actual theory and design is a bit lost on me sometimes.

  3. As someone who runs a website I understand the frustration on both sides but....

    I once tried to pass my site on to someone else and found it plastered with I hate AOL graphics and wonderful features such as "My collection of hats". Apparently he only owned two hats and he even spelled one of them wrong. Needless to say I regained control of the site ASAP.

    When your site is representing an organization it's important to, at least try, to appear as professional as possible.

    Hey now no advertising in the forums!?

    yep I are a smart :moon:

  4. What about conrod & bearing? If was doing job i would split crank! And are gearbox bearings ok?

    I have not split the motor yet, but so far all indications are that those are all okee dokee,

    I will know more after I actually split it.

    Just trying to get a little more info before tearing into it.

    Thanks all.

  5. I am going to be changing crank bearings and seals on a TY80. Before I tear into it I would like to have my parts together, the only thing I am unable to figure out is if there is a center gasket or not. Did they just use RTV silicone or Yamabond and not an actual gasket?

    So far this is my list of parts I will need: (if I missed anything please let me know)

    bearings

    seals

    head gasket

    base gasket

    rings

    crankcase cover gasket

    Reed cage gasket

    Thanks

    on edit: I did do a search here, but was unable to find the info.

  6. Now THAT made me laugh, and I tend to agree with it pertaining to non-AHRMA events.

    Jon

    Glad I could provide a chuckle.

    Why not pertaining to AHRMA events?? :blink:

  7. First I will preface my statement with this one:

    I am not totally familiar with the exact situation.

    Trials is about the ability to control a motorcycle, not how long you have existed on this planet.

    So any tie breaker should be based on ability to control the motorcycle. I.E. section ride off, Wheelie contest, bunny hops, balance contest, being able to urinate into a gas can 5 feet away while doing a nose wheelie. etc. etc.
