Sup? So, I haven't been on here much lately. Life and stuff. Figured it was time to really get started on something cool though, and that was a perfect reason get back into the DTT swing of things. So here it goes.

Awhile back (a couple years now maybe?) I picked up a mostly there '81 GS650 from good old Brad. Since choppers are awesome, that's been the plan since the get go. Awhile after getting it Brad, Jussy and I cut it apart.

After that I dragged that mess into the corner and it just kind of sat there. For AWHILE. New job, family crap, utter laziness... We all know the game.

While it sat I started buying up some parts. Best of which are these wheels. Still need to get them up here from Alabama, but all in good time.

They're originally for a CB750 but that's no biggie.

Grabbed an awesome (brand new) high dollar solo seat for next to nothing, a 70s Triumph tank, TC Bros "builders kit" for the hardtail, some unknown 4-1 header and some other bits and pieces along the way. I'll get some good pics of all that stuff in a few.

Pretty much have all the "off the shelf" stuff sorted. It's a chopper so of course there will be as much home made goodness as my limited skills (and friends with real skills will help with ;) ) allow.

Not looking to change the game here. Just a cool, fast, simple chopper that hopefully ends up with a naked viking lady painted on it somewhere.

Thanks to the current end of days scenario that we're all living through, I'm "working" from home most of the week, so I'm hoping to make some actual progress on this project soon.

Clutch - any better thread intro and I'm a stinking bishop. Know nothing about choppers other than I think they're cool and I want one.

That's quite a ding in that front rim. Thank goodness you are not closer to me or I'd lend you my frame jig and then I'd need it before you were finished with it. Good to see you back.

Clearly, someone is starting to threaten his lead on post count so he figured it's time to get it together and start posting again.

True, but luckily those Invader wheels were made from plain old steel. Going to get it straightened out and then both wheels will get powder coated.

Tank I'm going with, obviously just sitting on the pile. Always loves the look of the old Trumpet tanks, and seeing one sitting on top of a Japanese I4 motor gives me a weird sense of joy.

LaRosa seat I found at a clearance sale. Got it for about 10% of the sticker price. At first I wasn't in love with it because it's a tad larger than the styles I prefer, but with the width of this motor I think it'll look appropriate. If not, seats are easy to change.

4-1 of unknown origin. $10 ebay pickup. Has a few substantial dents, but nothing that can't be made right. 100% unsure of what to do after the header. I figure I'll make a decision there once the bike is mocked up and I can get a better feel for the overall look of it.

End game here is a nice and basic low slung chop. Some drag bike style to it, but 100% streetable. I want it to really function well. As well as a rigid short chop can. I'm on the shorter side (5'8" in work boots) so it'll be built to fit me. Everything tight and compact.

That said, I'll likely go with a lower mid mount foot control setup. Should be pretty simple to put together with the rear drum brake. Because I'm using the Invaders it'll be a single CB750 sourced front rotor and caliper. Cheap, easy and plentiful.

I have an old BSA rear fender in a box somewhere that will probably end up on it.

Speaking of the front end, I have this super cool remote reservoir front end off of an early Ninja that our man Hurcco hooked me up with some time ago. It'll get cleaned up and one leg will have the caliper mount shaved. The built in clip on style bars will stay.

As far as the heart of it, the GS650 motor, not a whole lot is getting done there. The main thing I want from the motor is reliability. If the period magazine tests are to be believed, it puts up a pretty solid 70+hp in stock trim. I figure that combined with a 300 or so lb. total weight, it'll be a blast without having to try and suck more power out of it. The one drawback is that the carbs that came w it are likely toast. Can't decide if I want to source a stock replacement set or try and do something fancy there. As usual, that will likely be decided after a couple beers and a quick check of the wallet.
