  1. To what end? Do you enjoy listening to the constant drone of an external fuel pump all day long? Fabricating a plate for the fuel tank? Plumbing an external fuel filter and fitting said plumbing into the injector? Determining the exact voltage to make the external pump run without taxing the OE fuel pump wiring harness/stator/regulator? Lots of work involved to replace something that works just fine the way it is. Why the desire for an external pump?
  2. Yup, looks just like my '76 MRR.

    Too smoky!

    25:1?? I run Motul 710 at 60:1 in aviation fuel in all the air-cooled Trials bikes I have (TY80, 304 Montesa, 348 Montesa, 305 Fantic....) with no problems at all. Pistons, rings, bearings and cranks are all happy and no drooling goo. Modern oils are SOOO much better than the goop that was available when that manual was printed. Just sayin'.
  6. Here you are! https://www.handdracing.co.uk/product-page/s3-a-piston-and-rings-kit

    Some help please :)

    Fantic 309 Honda 4-stroke transplant is.....different. Not internally geared for serious Trials use, but good for......something.
  8. You can also try Mike at the Tryals Shop. Lots of inventory, very skilled, has our TY80 cranks done in a jiff! http://www.tryalsshop.com/
  9. I would concedar such, but have no stake in this.

  11. Some might say a little too dog friendly. Hope to see you soon!
  12. Okay, I'll bite. 315s weren't made in 1979, they didn't show up until 1997. Don't mind helping out, but gotta know exactly what you have first.
  13. As much stuff (both new and used) that I've bought out of the UK, I figure it's a wash.
  14. I could do this all day. Kwak in Utah - https://saltlakecity.craigslist.org/mcy/d/lehi-1976-kawasaki-kt250-trials/6796685822.html And a 349 in Illinois - https://peoria.craigslist.org/mcy/d/peoria-1982-Montesa-349-trials-bike/6793511165.html
