Thank you Laitch for that.  I haven't had time to do much but work lately so no visit to the powder guy.  But I am not sure I like the looks of that exhaust in the link.  I may just not coat the exhaust with anything and just let it "turn."  I haven't decided. 

I was able to put the controls on and rebuild the front master.  I plan to try to route the cables soon if I can figure out how they should be routed.  Also need to figure out where the small ground wires that attach to the handlebar controls attach (on the other end, not the control end).

Is this small switch above the alarm lock cylinder standard?

Looks like I also will need the wiring for the temp and fuel level gauges.

I think I have a harness for the fuel and temperature gauges around here somewhere.

Question for the experts...is there a ground wire from the left hand controls (to ground) when heated grips are installed?  I have one on the right hand control but my wiring came with two ground wires so I was thinking the second one should be for the left hand controls but I don't know where it mounts.  Routed the grip wires thru to the hole in the bottom of the handlebars and it was much easier than I anticipated. 

More fun with parts from MAXBMW.  Great outfit and I have received a few shipments from them.  Seems like whenever I place an order I immediately think of something else I need.  Two attempts at buying a new choke cable on Ebay were failures.  What a mixed bag Ebay has been of late. 

I threw some of the fairing parts on this weekend to get a glimpse of what is to come and to see what parts I need for the fairings.  I know some of these are in bad shape.  The main fairing was broken in shipment.  I want to try refinishing the windshield and see what I get.  If it doesn't work out, no great loss.

Really wishing my bike was Bermuda Blue at this point.

I've successfully restored windscreens. I used a 6" loose cotton mop on a bench grinder and very fine buffing compound followed by Plastx. You need a light touch and keep the job moving as too much pressure or too long in the same spot will burn the screen.

That is good to hear Martin.  I was wondering what product would be best so I need to source some Plastx.

At least your paint is in decent shape (judging from your photos, anyway). And that gold is so 1987. I seem to remember a lot of Toyota Avalons that color.

Before you go out and by the Meguires Plastx try using toothpaste. While at the guild today one of the guys had some scuffed Perspex and El Presidente said he just uses toothpaste and elbow grease to get out the scratches.  The buffing sticks that I use first are fine or ultra fine and are white in colour.

I've used Jiff, because it's cheaper than tooth paste, because I'm a cheap bastard, for plastic headlight covers, etc. Probably in the U S it's a different name,  tooth paste like consistency for cleaning shower bases etc. That's for acrylic. I've got rid of scratches on polycarb with a soldering torch,  about four inches from the screen looking at an angle that reflects,  as soon as you see it go glossy, move to the next part.  It wood be good to practice on the lower part,  which isn't so important.

You need a lot of patience with heat,  a little bit too long in one spot,  it overheats and goes white.  Even then you can file it out,  but again you then need a lot of patience.

If the previous owner used Windex with ammonia there won't be much you can do for your windshield.  Along with the sun that stuff will cause discoloring and breakdown of the plastic below the surface.

If you plan to do any paint in the future, it might be a good investment to get a Harbor Freight dual action buffer and some 3" foam pads.   Along with some 3M Perfect-It #2 and #3 you can do some really nice things to your paint, windshield and your car's plastic headlights.

What's funny is I was really thinking about what it would take to change the whole bike over to blue and yesterday my wife took a look at it for the first time with the fairings on.  She said she like the gold/bronze/Avalon color.  So there you have it.  Gonna stay with the original color...I'm pretty sure.

I have heard that toothpaste is an option.  But I don't know.  Probably give the Plastx a try first.

TMG, I suppose I won't know until I try.  Good news for me is I did get a DA sander last year for Christmas, so I have that.  Plus I have some polishing compounds for cars and some real fine stuff for guitars.  Heck, certainly easier to just buy a new windshield but where is the fun in that?

The heated grip kit 61312300383 or 61312300382-(with bars ends) only comes with 1 ground wire 61122303023 which is called 'Tubing' on MaxFiche

I see no mention of where ground wire begins and ends connections in 01299797139 Install manual.

Can you describe where you began and ended the ground wire connections?

Thanks Volador,

I connected the ground wire (tubing) to the small socket head bolt on the right hand control near where the accelerator cable connects.  I terminated it under the tank at the main ground point.  There is plenty of length to do so with full handlebar movement. 

My apologies, I thought I had replied to your PM from a few days ago.

Work continues on the bike in small steps like bleeding the brake lines and getting fairing parts together, etc.  But I am excited to show that my seat came back from the upholstery shop and I think it looks great.  Took the Corbin seat and had it redone with new leather and cushions and gel inserts. Yes, that seat is a little much for a sporty version but I think it fits quite well aesthetically with the LT version.  Now it was sort of a trip to get here...

My first seat was the factory seat in some sort of grey with rips in it.  Not pretty or comfortable to me.  So I thought, no problem lets just get a new seat (I should have just done that) but I saw a few used ones listed on the Bay for what was reasonable and I figured might as well give one a try.  So I bought one that looked pretty good except for a small tear which I though I could repair, then I would have a serviceable seat for little investment.  Well that seat "looked" decent but when I got it was mostly junk.  The brackets that bolt the seat down were rusted so bad that when I removed the first bolt the bracket just snapped off.  All the bolts were worthless.  Great, not easy to replace those without taking the seat apart.  Plus the cover itself was so aged that just pushing on the seat cracked the cover in multiple places...no good. 

So I bought another one that was similar, but included the backrest portion and all good brackets but was otherwise a mess.  I was able to use parts from both to take to the upholstery shop and get this one made.  I am really happy how it turned out...and very comfortable.

It's just resting on the bike, not attached at this point.

FYI, you might notice in the background I have the Triumph apart to get it repainted.  Too many projects at once!  It's a sickness.
