  2. The 75-76 TY 250 skid plates were aluminum, same bolt pattern as the 74-75 Fred take a look at http://blackcatvintagetrials.com/2009/10/30/freds-fancy.aspx lots of mods
  3. We've used 80/100 to 1 for years, hasn't caused a problem. Taken motors apart and have had oil in the bottom end. Used in current year GG's and vintage TY's Fred

    Does anyone know how much a Pro motor weighs, standard engine, aluminum cases? Fred
  5. famousamos replied to famousamos's topic in Yamaha
    That's about 15 pounds lighter than a 250, little more bore and stroke, could have a bike in the 170 pound range. Fred

    You could use JB weld, we use it to repair hydraulic rods, engine blocks, and what ever. Super glue works on smaller nicks. Fred
  8. when setting sections, its best to make them too easy rather than hard, someone will have fewer points and win the event, or do gate trials events, let the riders pick the line that they can clean. Fred

    When I had the work done, I was told that the piston was from a Kawaski personal water craft, lots of power, with most of our meets at 5000 ft to 9200 ft of alitude, the bike pulls real strong even with 2 head gaskets. Fred

    The flywheel side will work on a 74-75, the clutch side requires trans shaft and clutch from the 75-76 TY Fred check out how I modified the 74 clutch cover http://blackcatvintagetrials.com/2009/10/30/freds-fancy.aspx
  11. I used the Boysen reeds for the TY250 twin shock, big improvement in low speed performance. Fred
  12. Here's a blog that Tony Down did on my TY250 http://blackcatvintagetrials.com/2009/10/30/freds-fancy.aspx Fred
  13. Check this out, story on my TY by Tony Down http://blackcatvintagetrials.com/2009/10/30/freds-fancy.aspx Fred
  14. We have drained the trans, filled to proper level with premix, run until clutch starts grabbing, drain and fill with trans oil Fred

    I ride a 74 ty that's a 290 now, 75mm bore, pulls like crazy at our altitude, events at 5000 to 9200 ft. Tony Down did a blog on the bike, it at http://blackcatvintagetrials.com/2009/10/30/freds-fancy.aspx Lots of mods done. Fred
