OK - another day, another post.

The controls were next. Handlebars, levers, mirror mounts, grips, cables in place. I was able to get outside between showers and get a few pics showing the progress a bit better.



The lever ounts were stock and some modified mirror mounts were added, as I really hate the original style which tend not to stay put well. I also adapted some "dogleg" levers to work on the bike. The brake lever being a challenge, as the lever did not include a little nub to operate the early style brake switch which mounts under the lever.





I took a stock lever and laid it next to the dogleg to locate the spot, then drilled a small hole, and inserted a roll pin to operate the switch. Cheap and easy, and allows the later levers.








The rubber lever covers were located in a NOS bin of aftermarket stuff at a place called Bent Bike in Lynnwood, WA. Nice to keep the lever clean in really bad conditions. The bike is also using the repopped grips from the Motobiker store on Ebay . The ONLY grips to make the bikes like original.

I was next able to get it off the stand and test the shocks, both the front and the rear feel really nice.



I used 7.5 lbs oil in the fronts and the Showa shocks on the rear are set at their softest. I may need to increase both of those after riding it a bit. The steering is a lot smoother now, after cleaning and re greasing the steering head. This bike also has a factory steering damper designed for the DT series which is a direct bolt on! These really help on a bike which is mostly street ridden. Fits up under the steering head.

I was able to locate a couple of NOS factory paper air filters so the bike got a new breather!


I also spoke earlier of the NOS Torque Pipe that I got from forum member Enduronut. I was not ready to install it when I wrote this originally, but I had to get it out of it's hermetically sealed case and test fit it......

As you can see - it feels right at home!

The tires are Chen Shin. 4.00-18 on the rear and 3.50-18 on the front. They are copies of the old Dunlops and actually ride out pretty well. I will find a set of streetable knobbies in similar sizes for the bike, 'Cuz I really like the look of them. I have an extra set of wheels I could use for them too.

I will still be installing the stock pipe for break-in as we discussed. I just had to see what the chamber looked like on the bike! I really couldn't be happier with it! [:-!]

Since I planned on riding this bike on the street, I later did a short test on the comparative noise levels of the factory VS the Torque Engineering pipe. I live in a town where the police are not too strict on such things, but it is interesting. NOTE: The pipe in the test has an aftermarket spark arrestor which will be documented later in the thread.



More on the way!

I'm currently converting a AT2 125 to a 175 as well. Can't wait to a have an electric start 175. Would love to find an after market pipe for it too

Your project is looking awesome. I'm envious of that nice pipe. My CT1 pipe is getting the works as we speak.

Sleeper!

The sleeper pipe on this bike would be the ultimate upgrade. The chamber is really overly wide, so it is a bit uncomfortable to ride with it - however, it Kics Butt with the better exhaust. If you build a true sleeper pipe then you will get the performance as well as the riding comfort, and of course, the correct "look".

If you are building that yourself, please start up a thread and document your work. Lots of folks will be interested!

Alas tis not my handy work. Handed it to Dave and Don at the Boron ride last weekend. Should be ready for the land speed attempts at El Mirage dry lake bed this weekend. I'm not competing. Just watching and putting around.
Your bike is looking real nice.

Give them a call and tell them to document the build and post it up :P

Seriously, I suspect there are a lot of other folks who would be interested!

What a great story! The similarities are too vaste here though Mako. :ohmy:
The first bike that I got my permit with in the same year, 1974, (the day I turned 15 1/2) was a yellow AT1 exactly like that, that I bought from an older neighbor. It was the first bike I snuck on the open highway, as well. That poor little thing made a zillion store runs.
I also later converted it to a 175 from a parts bike CT1 that I got for free. The downside was my electric start never worked and after a while, the battery would quit charging. Being young and broke, I converted it to the flywheel mag setup off the CT1 and never looked back.
The power difference between the 125 and 175 was obvious. My old Yamaha dealer back then told me that the 125 with the electric start and milder power characteristics was really made to be a "wife's bike". Not sure how true that was....
I finally stripped it with some mild porting and a Bassani pipe in 1976 for strictly "motocross" use when I got a Honda CB 350 for the street.
Great memories indeed! Thanks for sharing!

I'll Give it a shot.

They may not want to give away trade secrets.
