Here is a little build thread on my dt3 build. Its going to be a cafe style build with a bratstyle seat. Ive already got a bit of work done to it and i have a thread on yamaha-enduros but i thought i would share it here as well.

So im just gonna start posting some pictures and keep you updated with my build.

So here is what the bike looked like before I did anything to it


So pretty early on I shortened and detabbed the rear loop and bent up a seat pan for it(you will also see some crude rearset mounts but i ended up redoing those)




Then I took the bike apart and detabbed the frame and welded on tabs for the rearset mounts


Next I cut out some new rearset brackets




After that i put assembled some of the bike so i could do a little parts mockup and measure how much i needed to shorten the forks


After i shortened the forks


Fabbed up some headlight mounts and clip on handle bars




And mounted the turn signals and made up a license plate mount


And thats just about where i am with the build right now, I should be taking the frame to get powdercoated soon. I will keep you posted.
 
Very cool. I love the old Yamaha Enduros. I had a DT1 for a while that had an RT3 engine in it... what a beast.

Good luck with the build!

Love the build so far.
Document the wiring on this one if you haven't done the wiring already.

Looking very cool,

Thanks,

Been a while but I got the frame powdercoated, put the motor back together and put it in the bike. Next I can start work on the wiring harness and making control cables.
 
Very Nice!

Which Trail Tech are you going to run?

The $19 one with 2 wires?

Looking great,

Jachana
 
Got some work done on the bike last night. I finished the shift linkage.
I had to drill out the shift lever and press in a sleeve to get a smaller diameter hole so i could use my M6 heim joints


Then I cut the threaded rod and gave it a little bend


 
Are you keeping the 21" front wheel or downsizing? Thoroughly recommend a fork brace when you get to that juncture. (Not that the front end will spend much time down on the Tarmac lol)

It originally had a 21 in the front but it has the optional factory 19'' wheel now. Do these flex a lot? Will a fork brace help?

Yep they will flex like spaghetti in every conceivable direction, however, even a steel mudguard will go a long way to mitigate it, and you have lugs available on the fork lowers to use. The more you can make the front suspension system work as a solid unit will pay dividends.
If one side moves up even a millimetre ahead of the other, by the time that is translated to the contact patch of a 19" tyre, you are looking at masses of misalignment and gyroscopic tomfoolery going on.
It's easy enough to weld one up comprising of two hoops, one in front and one behind and bolted to the fork lugs if you can't get a funky machined clamp.
