    Default GS550 in a hardtail sportster frame?

    so now its cold and its back to the woodshed for the bobber project(s). the wagon and the truck are stored for winter.

    so ive been looking at rolling chassis kits. id thought about getting one and using the engine from my 82 fxrs. but i hate to take that bike apart. but i also have this gs550 mystery engine that i havent actually heard run. (run well anyway). and i was looking and it appears at first glance that this mill will fit quite nicley in a roller designed to accept a sporty engine.

    my problem is i hate to commit to a sporty chassis and have the gs engine not fit/or work/ or run well. and be stuck with it and then not have my big twin fit in the frame. i thought the engine might sit over a little to the left to accomodate the drive chain but im not sure. ive got lotsa questions. i thought iron heads were left hand drive, but im not sure.

    heres the kit i was thinking about...http://www.choppersurplus.com/bikeki...smokingun.html

    ive not built anthing like this, but i have bobbed out a couple of early metric bikes for friends in the past and im not scared to cut and weld.

    any builders want to chime in?

    yeah, im leanin to a more traditonal look, but that thing is awesome! its got a steampunk feel to it. alot of things going on in contrast to the simplicity of a hard tail. what engine is that?

    Keep in mind, the inline fours will not have the low end torque of the v-twin engine.

    the more i look at it and weigh my options. i think im going to do a hard tail conversion on this gs550 frame. ill save a ton of money. but i have alot of parts to round up.
