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.

Good day gentlemen (and maybe ladies, I don't know)

Been a few weeks.  Mostly failure on my part but with a little positive news thrown in.

Failure in that I attempted to repaint the Triumph while working on the BMW.  Knowing that once I got the T painted, I would let it cure a bit and work on repairing and repainting the front fairing of the BMW which was damaged in shipping, I got to work.  Stripped the T tank and found under many decades of paint layers a tank which needed fixing first.   Badly dented but not leaking.  So I fixed the dents and sprayed primer and blocked then sprayed a beautiful dark cherry pearl base coat and lovely 2K clear.  All looked good but I actually wet sanded thru the clear in the tiniest spot and tried to spot fix it.  No good.  Have to redo the tank.  So I sanded it down and laid down color and clear again with my sprayer.  This time it looked worse for some reason.  Flaws in the clear.  The whole time my BMW front fairing was just sitting there.  Sadly, I did have to admit defeat.  I took the whole bunch to my favorite auto painter (he is great, just thought I could DIY).  Told him my woes and he says he will take care of it all.  BMW fairing first.  He asked me if I wanted the T tank and fender painted the same color (dark cherry pearl) and I told him surprise me, I don't care anymore what color it is. 

So in the midst of this I decide to redo the lexan windshield.  I really like this windshield but it needs work.  I tried to buff it with various products and Plastix and it did look better but not even close to what I want.  I think next will be just sanding it down like redoing a car headlight with increasingly fine sandpaper then hitting it with some 2K and see what I get. 

I did get the seat properly mounted and located a seat lock keyed to my ignition...(thanks duck).  Also got my sensor installed and run for the temp gauge and all the wiring for additional instruments in the dash.  Edit:  I did run the wiring properly and that's why you see no bolts in the cover to my coolant/oil pump.  And filled with coolant...ready to fire her up soon...very very soon.

Still missing a right hand mirror cover in Bahama Bronzit (sp) and need a part number for the rubber pad which sticks on the back of the tank next to the seat.  Did get some other things done but can't recall them all.

Thanks y'all.

Windshield: been down that road...twice. 

First, it has a 2K polyurethane clear on it to prevent scratching.  You have to take it all off to buff, and removing that crap is a b!tch.  Try 3M Perfect It #1 on a buffer.   Once you get it off, 3M Perfect It #2 & #3 with a DA polisher will do a decent job. 

It may be possible that the shield has been out in the sun a lot and somebody cleaned it with ammonia based cleaner and it will have crazing that goes well below the surface and can't be buffed out.  That crazing had a yellow tint on my K75S shield.  In that case, you might want to consider painting it with a transparent tint and clear.  The tint will hide the microcrazing, and isn't that big a deal since you are probably looking over it.

Thanks Gryphon, now that I think about it sure does seem like it already has a 2K clear coat on it and no amount of DA buffing was really making any progress.  I will go with your approach and see.  I don't really want to buy a new one.

That Triumph is really nice. 

Wore comes to worse, you might have to go with wet 2000 to strip that clear.  You gotta remember that it's there specifically to prevent scratches.
