Voltage regulator Location

So I gave a DT175H from 1981. The previous owner ripped out all the original wiring and components that went with that. I am trying to make it road legal again so adding back lights, horn, etc.


I am seeing in the wiring diagram there is a voltage regulator and I bought one off of eBay, but I am not quite sure of the location on the bike. Anyone know where it is suppose to go?

Thank you! That helps a lot. My bike is missing that bracket… so I will try to find or make one!

AT1/DT125 Armature Puller

I am rebuilding my DT125 and I’m trying to remove the armature to split the cases. I have the tool on order at partzilla and Yamaha (90890-01111-00).

Both have ne eta. Does anyone have one I could borrow?

Adjusting the shifting forks on a DT1

It looks like I may need to adjust the shifting forks as on page 31 in the DT1 Service Manual. Would this need to be done after any rebuild?

Page 31 .... Hummmmm ... could depend on what version of service manual you are veiwing.


I will say, that if the service manual is followed from start to finish, that would eliminate "most" of any problems that could arise.


There is a shifter mechinism adjustment that must be done/adjusted correctly.


I must say, it's Kind of hard to help with something like this without being there in person. Pictures "might" help

1969 DT1 Shift problem

I have this 1969 DT1 that was rebuilt and after the cases were put together it shifts up to 4th gear put then it's a solid block going to 5th. Can anyone help me with this problem? Thanks, Steve

Hello skoppang


Could be any number of things. I recently fixed a 68 DT1 engine with the exact same problem, and it turned out to be ... that whoever was in the engine before me had left out a particular shim on the secondary transmission shaft, that prevented it from going into fifth because the shift fork couldn't complete the shift (throw/movement) without it.


Another suspect area to check would be the shift cam detent mechanism.


Note: Often times the transmission shaft must be rotated a bit to complete a shift, because the cogs on the gears aren't nessesarily lined up.
