Started locating things on the bar, just to see how it looks and what works best,i got another handlebar - wider and lower and i'm conflicting which one to use.
20130918_154131.jpg


The issue of electrics is a big concern for me, not so much from lack of knowledge but more from the desire to simplify the system, make it reliable and keep it "Neat and concealed"
so i'm trying to plan how to mount the components in the limited space i have under the seat pan.

Moving on to the engine, it started and ran at idle before i got the bike,so i know it's more or less ok. but still i want to take a look inside,de-carbon the head and pistons,put some fresh gaskets and generally make sure everything is in place.
My main concern is the timing, there are deep scores on all of the black tensioners and even inside the head cover.
Do i need to split the cases for changing the the timing chain?

Head looks ok i think, dirty but no visible damage.

Cylinders also look good, no gauges or scratches
20130919_162401.jpg


Pistons are dirty but not heavily, the piston has 0.5 on the top,i guess it was oversized at some point.

Mate I'm lovin' the progress!

My opinion... lower/wider 'bars will potentially give you a bit more control, but just my preference...

I'd also look at mounting the R/R under the electrics tray to make sure it has lots of air flow.
 
Looking at those pistons there has definitely been some contact with the valves.

Either the timing was that far off or it was way over-reved.
 
Just few little things iv'e done today
Was able to extract a broken bolt, it's one of the 2 holding the starter in place
20130926_193603.jpg


Stator cover had ugly deep scratches (no cracks) so i filled them with JB weld

I also have this bars, which one is better\nicer looking?

Going on with assembly

New clutch plates about to go for a dip

Few hours later...assembled (new springs too)
1383609_622803301103091_1758551464_n.jpg


Rebuilding the carbs, although i didnt "shine" the outside - i gave it a very good clean inside and out and made sure all the passages are open and clean, replaced the gasket,the rubber plug and all o-rings.

I'm having a bit of a problem locating this part, i belive it's a part of the choke mechanizm but didn't take any "before" pics.
20131019_185336.jpg
 
Getting there slowly, rebuilt the timing tensioner, adjusted the valves and i'm ready to put on the head cover.
still missing two of the four side cover for the "half moons"
and the decals for the clutch and stator cover (those things are ridiculously expensive - for a decal)

Looking good! Must be getting excited with it so close to being together?
 
Little more progress,
I re timed the cams and adjusted the valve clearance (after i understood my mistake of timing according to the |F mark instead of the |T)
i filled little oil in each cam "pocket" and closed the head cover.
since i'm going to use an electronic rev counter, i plugged the cable exit - nice that Suzuki have OEM parts for this.
20131030_222213.jpg


Also go some new plugs
20131030_222310.jpg


20131030_222526.jpg


This is my under seat tray, where all the electronics should be installed, i'm trying to figure out what would be the best placement for each component.
20131030_220557.jpg
 
Nice, I did the same with the tacho plug when I put my Acewell in, very neat.

With my tray under the seat, I put my R/R and starter relay underneath. The extra air flow is good for the R/R and the starter under there makes it a bit easier routing the fat wires for the starter.

It's something I'm considering, but i want to keep a "clean" and hide most of the electrics.
maybe I'll drill some holes for air intake in the tray
 
after 9 months separated, the engine and frame were united again today
I did it all by myself so managed to scratch the frame a little. but other then that it went well.

I'm not 100% ok with the seat, might take it back for some modifications
 
Working on wiring...so far all this bundle was removed )probably will remove little more)
20131113_225151.jpg


I've replaced the R/R with a modern series unit, and will use a small anti gravity battery, will also incorporate relays for the light and coils,and replace the singlr fuse with a modern fuse box

Good stuff mate, in hindsight I really should've taken the time to do up a custom harness, would've made some things so much easier!
 
If i had unlimited budget i would replace all the bulky handlebar switches with modern minimalistic units
