    This is a joint build between Dan ( Taylar Motorbikes ) and myself the bike is in between Dan's house and mine during the different facets of the build and fabrication it is a tribute build of a 1911 Indian BTR


    The engine for this bike is a moderately modified PK 69.5/80cc I had sitting around so we decided to use it for this build.

    The bike is going to be a deep Burgundy, Indian never painted their bikes this color however as the bike sat aging ( a 100 YRS. or so ?) in a garage, a basement or old barn, the led in the paint blended with the metal of the bike and turned the color into a Burgundy, most people that find an Indian in it's declining stages often restore the bike using the Burgundy color thinking it was original but not so, no harm no fowl as it doesn't decrease the value of the bike at all and we thought we'd do something different for the color

    Here is a couple pic's of the Frame on stand, Forks & Tank as we start the build, the forks are actually from a 1936 Rollfast and the color is what we're going for.

    And the final results on the engine, both bottom end gasket and head were hand made with automotive grade gasket material and pro racing aluminum gasket material as well as treated with the copper coating and automotive grade Allen bolts for the head torqued to 12ft lbs, the NT carb was re-jetted and the compression is very good on this little engine.

    Yes the edge was broken so we cut that portion off and still have 1" of thread, made a shim for the bolt and it actually helped align the engine very well, the engine was inspected and there is no other damage, could have been bumped during shipping, maybe done at the factory ? I dropped one during paint and the same damage accured still got that one in the closet.

    Fabrication of the motor mounts and fitting today, we decided to use the squared tubing and then we fab'd an aluminum plate all shined up to go over the top and bent the edges over about a 1/4" to match the faux crank case, the crank case will look like the Redskin's without the dress up and line Ah! well maybe later ? haven't got there yet.

    The crank is a Schwinn Sting Ray 5" as well as the cups and bearings with a Worksman 36 tooth sprocket the wheels are Huffy with 12 gauge spokes that have been re-trued and snugged up a bit the whole wheel will get powder coated Black with cream colored Duro brick pattern 26x2.125" tires, and good Ol' Schwinn tubes.
