    Default To stretch or not to stretch...

    That is the question.

    1980 GS850L with almost nothing untouched. I’m going for a certain look using some rake and a lot of lowering but since I’ll be cutting out the triple backbone and doing a proper hardtail, my question is, does it need to be stretched. I’d like to avoid it because the driveshaft then has to be lengthened but I’ll do it if it needs to be stretched for the right look.

    I think the bigger GS bikes are long enough as is but I don’t want to get too far before I realize it’s too short and looks dumb.

    With just lowering and some dismantling and handlebars I’m not actually gonna use, it looks like this:

    Any opinions? And I guess Uncle Sam is the look I’m going for:

    I'd pull the cover off the driveshaft and lengthen it. Naked shafts in a real hardtail look way cooler than hack jobs with the swing arm still in place.

    I assumed the fact that I wrote I’ll be doing “a proper hardtail” was enough information to show the swingarm wasn’t being used, no?

    Obviously I can’t force anyone to post with constructive advice but Im simply asking if my frame needs to be stretched to match the overal shape or silhouette of my inspiration, the Uncle Sam bike.

    In the pictures I posted of mine (in the early stages), even though they are not fully side-on shots, it appears to me that the wheelbase is long enough and with some added rake and some lengthening of the fork tubes, I’ll have the basic shape I want. I also believe the backbone, which again, will be a single backbone, is pointed in the same direction, that is to say, both bikes pictured have the backbone pointed to the same spot on the rear tire.

    Just asking for some else’s opinion with an eye for proportion. I know for a fact there’s smart guys here. Hopefully a few will post.

    Thanks in advance guys.

    Observe the geometry of transverse four (not Harleys, they aren't transverse fours and will not correctly convey finished proportions in relation to YOUR engine!) which look like what you want then do likewise.

    There are plenty of pics of vintage Japanese choppers to study. You can also visit swap meets etc and directly measure wheelbase, stretch etc.

    Dam you're sensitive I thought I was agreeing with you.

    Sensitive? I’d seen your post about the swingarm still being in place. It looked as if you thought that was my plan. Just clarifying is all.

    This’ll probably be a short thread but at least you’ll have the stupidest, most useless post in it.
