78 XS 750...special to tracker/scrambler
« on: Jun 14, 2016, 12:18:46 »
So my main bike is a 2015 Mag wheel Bonneville but here in Nova Scotia we have some beautiful scenery along the fundy shore bit it's all only accessible from grated gravel and fire roads. After banging my exhaust on the bonnie a couple of times I figured I better look at something else for my off road adventures. Well in the garage I had this 78 XS750 triple that I was thinking about a café build for but the "Special" version of this bike that was more popular here in Canada than the " standard" version  the UK enjoyed made a cafe build more expensive and difficult.  So a tracker/scrambler build began to take shape in my mind.
I've lurked here a while so I thought it was time for a build thread. Now I didn't take many pictures of the starting point but here are 2 to kick off the build.

Earliest pic I have of my starting point.

I've since stripped it down some. This is not going on be a frame up powder coat restoration at least not yet. I don't have the funds at this point and the motor is in dubious health so ill get it on the road and see how it goes before I commit to a complete teardown... maybe over the winter.
I touched up the frame with Tremclad, cleaned up the forks and painted the lowers. fork seals are not leaking yet so a complete rebuild will come later. Cleaned up the triples with much rust removal and new paint, it has tapered roller bearings already and they were in decent nick so they were washed in wd40 then repacked with grease. Forks will see new ears and gaiters. Headers were sanded and painted with VHT header paint... may get wrapped later. Rear fender was bobbed but the plastic inner fender was cleaned and retained. This in not California and this bike will see bad weather so I want to maintain some crud protection. Stock airbox was in rough shape so it is getting pods (yeah yeah i know). Seat pan was completely rotted so it was trimmed and will be covered in plastic and used as a fiberglass template for a brat style seat.
I'm cheap so I reworked the stock tail light and I'm looking for signal light that will work with the look I'm after.



Also got longer shocks from a triumph Thruxton to bring up the rear to improve the lines and balance the longer "Special" edition stock forks. Will also increase ground clearance.


Here's how it sits now...

Looks like a good project making progress, cool.

If you're thinking about changing the tyres, it'll end up looking a lot like my CBX550, full guards due to UK spring/summer/autumn/winter rain :-(

Oh yea these tires are all dry rotted they are just on it so I can roll it around the garage. It's getting some dual sport rubber. As of right now I'm thinking Shinko 705 's or some Hidenaeu Scouts. This bike will be doing gravel roads.

Ps. I've been watching your build Noriders looks sweet I love the CX's!

Some minor updates. Got the headlight bucket painted and mounted with some generic ears. Tank was derusted, found some pin holes around the filler cap so out came the MIG ( no pics because my welds are ugly). It got some minor bondo and a thick coat of primer to tell me where to spot putty. The fiberglass seat was trimmed and cleaned up some then wire frames added form the rear shape for stage 2 of the fiberglass. Front brakes are also rebuilt and back on.




That's it for now... next job will be to wet sand the tank spot putty any little spots and start applying primer and topcoat.  Then rebuild the petcocks converting them to manual (vacuume elimination).

Some more progress. Got the tank painted.
But I think it needs something more than just a solid color.. Yamaha logo in black or white maybe and some sort of stripe maybe?


Got the rear brakes back on so the next step is to get some fluid in there and bleed. I rebuilt the petcocks but at least one is from a different year later 850 maybe... in any case in converting them to manual following the guide on triples.org I still buggered one up and drilled through the casting. I think it will still work in off and on position for the short term but I think I will bite the bullet and get a couple of new ones from Mikes xs. Net. Starter button is broken in the switch housing so that need repaired and the clocks are apart getting some flat black. There is some rust damage to the chrome cups that I made a quick and ugly repair to with the MIG but I slapped paint all over it anyways as I don't think they are staying long term. New fuel lines and inline filters for extra protection  for those clean carbs and its time to test that tank and petcocks next... see if she will fire. Still have to do something with the exhaust mufflers and get back to that seat!

I'll take more pics I promise..
