gatosbros XR600/650L scramblers

Love that tank......cool thread how did I miss it?
The man has some skills..

Quoting cycle wizard's reply to a PM I sent him about this for everyone else's' benefit:

45's huh!?! wow. Would like to know more about these intakes that you're working on. Any idea when I might be able to get my hands on a few of those? And Lemme know if you need any help with CAD modeling or whatever. Oh, and would we still need to use a Noss adapter on the other side of using the stock air-boot?

Yep you would still need the air box adapter but the new intake is going to be longer so it fits the air boot better.
I'll post a pic of a billet intake that I'm building for a national flat tracker, he's running one of my 750 motors..
It's a Knight frame twin shock so I'm making a straight intake for it that will fit his 48mm carb..

To bad you couldn't relocate the rear shock I could build you a cross flow twin carb billet intake.
Two 32mm carbs with pod filters..

Please do post some pics. Would love to see what you're working on.

Made some more progress on the tank, and took a bunch of pictures with a new camera that I just bought, but I can't figure out where I put the damn things. So here are a few crappy cellphone pics instead. Started re-shaping the underside of the tank, and what these don't document too well is how I fit and shaped and cut the sheetmetal, tack-welded it into position, installed temporary supports, taped-off the interior volume, filled it with expanding foam, and then cut away the excess. The whole point of this was to, 1) maximize volume, and 2) make the tank a bit easier to reproduce.

Also spent a bit more time re-shaping the topside of the tank and it's looking a lot better. Funny how a few small changes can all add up to make such a big difference in the overall look and feel of something. Or maybe I've just spent too much time fondling this tank...

Keep it coming Jesse!

Very nice!

Haven't had much time to work on this project lately, but spent this afternoon mocking-up the new subframe. It's pretty wonky, but just wanted to throw something together quick-like. Gonna make some small adjustments after I fit the rear fender, then make make a jig and I can weld-up the real subframes.

Sweet project!!! Subscribed.

Is this going to be a carbon fiber fuel tank by chance?

Yeah, it's going to be a mix of carbon, kevlar, and fiberglass. At least the first few. Might eventually look into having them roto-molded.

Didn't I sell you that bike about a year ago? Ether way, very nice work.

One of 'em, yeah - the XR600 that I'm building for my buddy Sean. And thanks.

Hi,

cool thing to build your own scrambler tank. For my 1988 Dominator I' ve choosen the easy path and used a tank from an old NSU Max (and a few others things from 1950ies bikes)





Something you may want to consider is an oil controll tube, a good thing since the XR/NX 650 oilpump is infamous for making trouble






Cheers, Michael

And to think that there are some bureaucrats in Euroland that want to stop owners from any modifications to bikes!! Keep it up.

I like your Dommie. I have a fondness for them (see my signature line). I don't want to hijack this thread. but I'd like to hear more about your bike. Do you have a build thread for it somewhere?

Neat-O! Thanks for posting scrambler66.

Started working on the rear fender today. Bought a big stupid steel chopper fender to cut-up and use to make a plug, but it's so wonky I kind of wish I would have just started from scratch. Cut some width out of the middle and trimmed it down to just a little bit over-size. Not going to do much more with it until I make a new subframe to fit it to for real-real.
