Thanks. Defiantly like the pic of the front tire . I'm going with the avons on my bike when I get to that stage in the game

...WOW... you do really nice work. Thanks for sharing. You've convinced me to put knee dents in my k8 tank because now I know how it will look with the new tailcone

That is pretty cool. The obvious questions are, will you put ass dents in your tail section and will it be used as a reserve tank for long rides?

Have agree, that's a cool tail. Did you use an old K7 tank?

Outstanding! I wish that I had thought of that.

Yes, there will be ass-dents, but they'll be covered by the foam cushion. I got the idea from someone on here some time back, I used a spare k8 tank so the lines would match. My skills aren't good enough yet to weld up a gas tank so its a glovebox. I had to move the door panel back to get the whole thing short enough. It sits on a shortened stock seat pan so it retains the stock hinges and key latch.

I don't think I'm ready to hang a "Custom Motorcycle Seats" shingle on the side of my house just yet, but overall I am pretty happy with the way my first attempt came out. I think it will look okay after I add the rear fender. I found an interesting "reptile" vinyl that I used for the top. I don't think the pics do it justice, but it has an interesting texture to it. I put the embroidery machine that I bought for my wife 5 years ago to use, so that was a plus.

Starting to get warm outside. Lots of snow melt today. So many things left to do. Feeling the pressure...

Another wow!... you have some nice sewing skills too! After admiring how well the lines flow on your new seat I see the very classy insignia on the back too. Keep up the great work, I'm looking forward to the finished tank/seat/fender reveal.

Stoli · « **Reply #59 on:** April 06, 2013, 05:00:02 PM »

Time to buy paint for the tank, fenders and side covers. When I started this project, I had a vision of gloss black all around for a simple combination of black and silver on the entire bike. Now I'm floundering a bit. I still don't want any loud colors, but not sure if straight black will cut it. I think the gray primer that is currently on the tank is skewing my judgment. $:-\$

I've also been doing a lot of reading since I primed the tank and suspect that I will be sanding off all the duplicolor primer (lacquer based) and laying some epoxy primer on before I put on the urethane base and clear coats. Most guys say that it is OK to put epoxy then urethane over the lacquer but it has a greater tendency to weaken over time due to the different expansion rates of the urethane and lacquer. Might as well do it right I suppose.

Thanks. I did that with a Brother sewing machine that has some simple embroidering capability. I designed the graphic for the speedo and tach faces using a computer graphics program. Then, when I was making the seat, I thought it might be cool to put the same graphic across the back, so I figured out how to import it into the machine that sewed it into the vinyl using some silver thread. Maybe a little egotistical but I figure we spend so much time and effort on these projects, why not put a small brand on them? A real man would have welded it on I suppose, but my welding skills are not so good yet.

Here is a closeup of the insignia sewn into the vinyl:

Quick update. Finally finished the fiberglass rear fender. Not sure what I think. It was such a pain to make, I am predisposed to like it. It's different anyways.

Here are some pics with the first coat of epoxy primer on the tank, fender and side covers. Got a bit of an orange peel finish on it so I have some sanding to do before I lay on the base coat.

At this point, all I have left is to fabricate some mounts for my DCC rearsets, bolt on the exhaust and then get this thing out of the basement and see if it runs. I plan on riding it for a few weeks before I spray on the finish paint.

So, I put the front fender on and did a little sanding and primer recoat and although there is still a slight amount of orange peel, it really changed the appearance of the bike. I was planning on gloss black but I kind of like the matte finish. The front fender sort of ties in the rear as well. I'm pretty happy with it at this point.

matte looks cool dude, nice bike i like it.

Wow, that looks great! I'm working on a '77 myself.

Basement Extraction:

Finished the rearsets and now it's time to get her out of the basement and into the sunlight. Built a "sled", strapped the bike down and pulled the contraption up the basement stairs on up a couple of 2x4 rails using a come-along. Would have made a nice redneck video for YouTube:

Stoli · « **Reply #66 on:** May 28, 2013, 02:16:35 PM »

I was pleasantly surprised when she fired right up! Sounds great and I haven't even adjusted the timing or balanced the carbs yet. I did do a fairly thorough manual adjustment to the points and carb during the rebuild but didn't expect it to run so smoothly before I did it with the engine idling. Took her for a spin around the block and she shifts well and runs like a top. Still grinning.

deafcaferacer · « **Reply #67 on:** May 28, 2013, 02:27:41 PM »

she looks beautiful!

flybox1 · « **Reply #68 on:** May 28, 2013, 02:34:01 PM »

like a kid being born into the world. clever way to bring her up from the basement.

great looking scoot!

Perfect analogy.

Stoli · « **Reply #70 on:** May 28, 2013, 02:58:08 PM »

I have decided to go with the matte black finish instead of the gloss, so when I have a chance later in the summer, I'll go ahead an put the finish coats on. For the time being, she needs to be ridden hard and often.

Stoli · « **Reply #71 on:** May 28, 2013, 03:06:36 PM »

What's next -

After the 100 mile break in, I plan on putting the pods back on and going down the slippery slope of rejetting and needle shimming. I know that there are many who would advise me not to, but I gotta at least try.

Also, I'm not too crazy about the muffler so will probably switch it out with one like this at Dime City:

Blitzburgh207 · « **Reply #72 on:** May 28, 2013, 06:02:44 PM »

That looks great man, good work! ps you'll love that muffler

Stoli · « **Reply #73 on:** May 29, 2013, 08:05:22 AM »

Rearset mounts on on a budget. I'll eventually clean them up and get them powdercoated. Just a couple of 1" strips of 1/4" steel sandwiched around the passenger peg bracket.

iron_worker · « **Reply #74 on:** May 29, 2013, 03:12:00 PM »

I love your method for getting her up the stairs! Way to work smart and not hard.
