SF...I also lost most of my teardown pics due to a faulty memory card so I don't have any pics of the wiring. However, I have another 350 that I can take some pics of for you.

The wire routing diagram is usually in the back of a shop manual...Larry

Great job. I am rebuilding my mom's 72, could you post harness routing pics around battery trey when you get to it. I've lost all my pics and am stumped....there's just something that doesn't look right. I also have a signal beeper and can't remember where it goes for the life of me. Looks better than new

The harness pulls to the left side of the frame and toward the back of the fuel tank as it goes to the battery box and also goes through the left side(as you're sitting on the bike)of the rear part of the frame(under the seat)on it's way to the taillight.

Well updates seem to be slower and slower. I was recently given a promotion at work so my days are a lot more full. I am now the Command Senior Chief for my squadron.

Anyway, I received and installed my new swingarm bushings. I kind of wish they weren't covered up by the rubber covers because they look so good.
I was able to get the swingarm installed, the wiring harness, and a few other bits.

I have the lower triple and stem in the freezer so hopefully tomorrow I will be able to install the bearings. However, I am a little concerned about the stack height. When I measured the old set and the new set side by side (including seals) the new set was slightly taller. From what I have read most people have to use one of the washers. It doesn't look like I should have to use one at all. I am worried about the headlight ears lining up correctly.

Love those blacked-out and shined uniform cyl. & head fins Harsh !

Congrats on the promotion.

You didn't measure the stack height?

Harsh · « **Reply #182 on:** October 22, 2014, 03:02:17 AM »

I did measure them. I had the old and new side by side. The new (with seal) is slightly taller than the old (with seal). I went off of that and installed the races in the frame. However, I am now wondering if I should not have included the seals in the measurement. Without the seals being used while taking the measurements the old set was slightly taller than the new set.

bjbuchanan · « **Reply #183 on:** October 23, 2014, 03:05:34 PM »

It's normally measured without the seal but a small amount in either direction really doesn't matter. Did you measure what the differences were or is it all eyeballed?

Harsh · « **Reply #184 on:** October 23, 2014, 03:23:03 PM »

I laid a ruler across them and eyeballed the difference. I am going to re-do the measurement. It won't take much to knock out the race. If I mess it up it is somewhat cheap to replace.

bjbuchanan · « **Reply #185 on:** October 23, 2014, 04:44:12 PM »

I have swapped over when I screwed up before, its not too much. From what I have seen you have more than enough skill to carefully tap that sucker out of there. Don't forget that the kit already has a tolerance on it to begin with and it isn't super tight.

My lower back has been hurting pretty bad so my time working on the bike has been limited. However, I finally received the LED headlight so I was able to install that. I didn't follow the writeup on it as I elected to use the rubber strip that was in the sealed unit. I put a thin bead of silicone in the corner of the mount then pressed in the rubber strip. I then put a thin bead of silicone in the corner of the rubber strip then put the glass on it. I pressed pretty hard against the glass to push it into the rubber while wrapping the entire assembly in duct tape. Set it aside to let the silicone cure overnight.

While I wasn't able to press the glass as deep as it was originally I was able to get it deep enough to be able to fold the metal over the lip of the glass. I could see the silicone just eking out between the glass and the metal so I am confident I have a nice weather proof seal.

I felt I needed to modify the back of the bucket a bit. In order to allow for the wires to enter the bucket and allow some cooling I had to open up the hole a some. I quick test fit showed that I should be able to adhere the LED box inside the bucket against one of the flat sides.

OEM and modified.

I also received my PAMCO electronic ignition so I installed that. My local electronics shop is closed on the weekends so I will have to wait until Monday to get the correct connectors I need to make everything plug and play. I have the electronic box hidden in the frame tube which should hide the box and wires nicely. I am going to secure it with some industrial double sided foam tape. Right now I am leaving it loose until I get the electrical connections done.

I was also able to get the bearings installed and the triples mounted. I am glad I went back and re-did the stack height measurements because I needed the thinner shim. And because I wanted to see how it looked I slid the forks into the trees. My tires are on order and as soon as the guy that trues my wheels gets back from vacation I will get this baby into a roller.

Nice! the LED is a good idea as the stock units were equivalent to maybe 3 candles or so...Larry

Harsh · « **Reply #188 on:** October 26, 2014, 04:29:01 PM »

Yep and it draws less power...win win

Harsh · « **Reply #189 on:** November 02, 2014, 07:51:43 AM »

Worked on some wiring yesterday since my connector kit and crimp tool finally arrived. Nothing too exciting, but it is progress. I managed to make a quick connect for the electronic ignition and it tucks very neatly into the frame rail. I also did a little rewiring to the front of the harness as well and added a couple extra ground wires. I also got the bike off the ground. It now sits neatly on the stands. If you look closely I gave the carb bodies a little love. I didn't like the dirty grey look they had so I cleaned them up some to make them shine a little bit. Sprocket and chains are on order. I went with stock gearing but did a 520 conversion.

Starting to get very frustrated that I still don't have my wheels back from being trued. Tires are sitting in the garage waiting to be mounted and balanced so I can get it into a roller.

You do nice work. I like the shinier look of the carbs.

I'll come down there and true them for you Harsh;if you want to pick them up from the man on Wed. Let me know

Harsh · « **Reply #193 on:** November 08, 2014, 04:26:32 AM »

Thanks for the offer Bill. I am supposed to get them tomorrow.

Connected the wiring that would be in the headlight bucket yesterday. Everything works as advertised and the engine turned over when I thumbed the starter. I had a weird issue with the turn signal indicator LED in the gauge. It would only illuminate when the left turn signals were on. All of the turn signals worked like they were supposed to. I swapped it out for a spare LED and it works correctly. Weird since the power for it comes form the same place regardless of the turn signal switch. The LED headlight is crazy bright. I will be purchasing one of those for my 750.

Are those LED headlights pricey ?

Harsh · « **Reply #195 on:** November 11, 2014, 02:15:14 PM »

No. I paid $25 shipped for mine. Although it took the slow boat from the Netherlands to get to me. There are a few different versions out there that might be a tiny bit cheaper.

here is the one I ordered: http://www.dx.com/p/20w-2000lm-8000k-motocycle-led-headlamp-w-angel-eye-12v-216822?Utm_rid=67723936&utm_source=shopping&utm_medium=pcs&utm_campaign=paidshopping&?Utm_rid=67723936&utm_source=shopping&utm_medium=pcs&utm_campaign=paidshopping#.VGKHCMmK1LQ

Just read up on the whole build... you do some outstanding work with great attention to detail. Looking forward to future updates!!!

This is definitely the raddest 350 project I've seen. Well done.

grcamna2 · « **Reply #198 on:** November 11, 2014, 07:37:28 PM »

Did you get your wheels yet Harsh ?

Harsh · « **Reply #199 on:** November 17, 2014, 03:19:00 PM »

Well nothing ever seems to go smoothly. I finally got my wheels yesterday so I mounted them. I took the wheels up to Cycle Gear to get balanced since they do it for free. The front took a bit more weight than I would liked to have seen, but it balanced. The rear has a noticeable high spot. You can see it when it rotates in the machine. They got it balanced, but I don't like it. I met a local builder yesterday that has a nice truing stand so I may give him a call and see what he says.

Regardless, I decided to mount the wheels and get the bike into a roller. The front goes on without issue. The rear however is another story. The sprocket I ordered does not fit correctly. The machined space is too great which allows the pin/bolt to free spin so it will never get tight. I have already emailed the place I bought it and am awaiting a reply. I am going to hold off on publishing the name of the place I bought them from to see how they handle the situation. None the less she is a roller now which will certainly aid me in moving around in the garage.

Stock on left replacement on right.
