DT100 Hipster Build (mantra: nobody is doing it)

It looks like in 78 they started introducing the style of carb/cylinder that I have as an option and then they phased out your style by 81 in the DT100, but kept it in the MX100 line until later.

Beside having the oil going directly to it, my carb also does not have a pilot screw on it.

Also, the autolube system on mine isn't connected to the carb or anything, only lubes the crank I think. I haven't done a ton of research and have just been running premix, but Ide like to get it set up properly. How is yours hooked up?

Here are a couple pics of the carb where the oil line goes in, and the other side as well.

actually yes the idle mixture screw is under a tamper/idiot/hypster proof cap

Sweet thanks! It doesn't show one on the parts breakdown either so I just figured as long as the channels were clean I would be set. It idles great so I think I will play the if its not broke card on this one though, I wouldn't want to leave the door open for a hipster in the future.
 
With the holidays I haven't had much time to work on Piper, yesterday I was able to get a few things done, today my battery got in so this weekend I can start working on the electrical and get it working, I replaced a brake switch, my exhaust guard was missing a screw and washers so I put those on, and I installed 4 turn signals.

I left my wiring diagram on my desk at work so I am waiting to start hooking up wires. For starters I will just have them hooked up like factory in order to get it inspected and on the road faster

The turn signals I am using come with a dual element bulb so I am toying with the idea of using all of the turn signal lights as marker lights, I may have to switch over to an electronic flasher and use relays to switch over. I was thinking of using the tail light circuit for the marker lights, I might have to switch over to LEDS to.

has anyone used one of the lawn tractor type voltage regulator rectifiers to switch a system over to 12 volts or update a 12 volt system?

I think I could cut my power consumption considerably if I went to 12 volts with LEDS.

New shipment in today, also found a surprise when organizing some shelves in the back, an owners manual for my bike with the wiring diagram, this will make my wiring adventure a little easier this weekend.

It was sunny on Sunday out at my dad's, which is where I have been keeping Piper, so I ended up going for a ride and cleaning the garage a lot and working on her a little.

I was concerned about getting a good ground on the turn signals. They are rubber mounted on the forks and I hate sharing a ground with the headlights, so I decided to run a chassis ground to the front for the signals. I only have single plug female connectors so I made a 1 male 2 female wire set up to give ground to both sides and ran ground wires into the signals so they are grounded at the light fixture.

I had some time on Saturday night to work on Piper's electrical. It was difficult because with the schematic and trying to find specs on the flasher relay I couldn't tell if I needed a 2 or 3 prong one. The plug on the bike has 3 prongs and I was worried that the 2 prong one I got through my work wouldn't do the trick but I found a 3 prong 6v flasher on amazon.

I tried the 3 prong first and all that happened was my headlight and neutral light flashed a few times and then blew the fuse. When I put the 2 prong one on it was money.

All of the lights are working, it runs and is fully functional, now its time to clean up the body and get this girl presentable.

I don't have any pictures of the actual work that I have been doing on Piper the last few weeks, I replaced the fork seals and gave her a shot of 20w fork oil. I mounted the new front tire, but found that the rim is a little out of true and has a flat spot, probably from being smashed in the storage container that it had been in, no worries I went to the local bone yard and found a suitable replacement for $30, just wish I would have waited to replace the bearings. The forks are straight so I am rebuilding the yoke. New bearings and races and re assembly should straighten out the front end and make it roll true.

I also got a cats eye tail light from motion pro. I cut the back of the seat pan to accept it and will be doing a solo style cafe seat with a bump. still waiting for the foam to come in on it.

I got a muffler from Hong Kong that I will be installing to replace the stock one. I will have it running lower to free up a little room by the rear signal.

I will have more pics to post soon, I am also getting ready for paint, it is getting to the point that I am making some real progress on this little girl.

I found a service manual for the previous year at my work and bought it as well.

Got the front tire mounted and the front end rebuilt, new races and bearing on the trees, forks rebuilt and it is still a little crooked, I think my trees are out of whack, but the local bone yard has one so I think I will pick it up next paycheck.

I pulled the rear apart so I can get the tire mounted. I am going through that side and get things cleaned up I decided to do some trim work on the rear fender, I will be switching up the exhaust pipe also. More pics to come, I hope to have this done by mid summer for the farmers markets.

Finals are done, time to get going again. I got the rear end taken apart so I can get it cleaned up and trimmed out, I also took the seat off so that I can install the new tail light
 
Oh, by the way, hipsters don't make things they "curate" them.
I think the 20wt. fork oil may be a tad heavy? I'd say 10wt. to start with. Cool, build.
Cheers, 50gary
 
one thing about 20wt if you but a qt it is enough to do those lil forks many times, you can use an old trick i use if need be you can change out the 20 wt with some thinned to a lighter weight
i use trans x auto trans conditioner to thin shock and fork oil when needed works very well for this

Its true, I am glad that I get the opportunity to "curate" this bike, it has been a lot of fun.

The guys here and I had a pretty long talk about this one too. I have the Yamaha service manual and it said that 10w to 20w could be used, in figuring that an adult would be riding it and that it would be in the city we decided to go with the heavier weight oil. If it was for a youth or for a camp bike I would have definitely gone with a lighter weight

Thanks for the info, back on the farm we used auto trans oil for the forks and wd40 on the air filters for our irrigation machines, I think most auto trans oils are about 7.5, but the conditioners were great for keeping the seals from leaking. I will probably throw some in on the next round for good measure.
 
Girlfriend kept me from the bike this weekend, but here strawberries will soon have a home.
