DT400 - the big-bang build: Big changes!

[stroker crazy]

A couple of packages arrived on Friday:



They contained this:



Too many parts missing or not repairable for this to be a Restoration so I'm posting in Specials. Will post the plan after some more thought.

I bet your mailman hates ya! lol
Pics like that remind me of being a kid and opening up a model car, very cool

Mine looked like that a few times

You know I love a good two stroke, and I love the DT's. I'm on board.

I'm having lots of trouble finding two critical components - oil pump and compression release.
Any DT400 parts are of interest, but without these two the project might not be able to go ahead.

There must be some still available somewhere!

I scraped a 400 motor a few weeks back let me call the guy and see if he hauled it in yet

Thanks bradj.

Thanks smv - made a bid.

Have you seen my other build in Specials - the RaZoR?

The Plan (subject to revision!)

                Engine:  All seals replaced, bearings checked and replaced where necessary, new clutch plates and springs.
                              Crankshaft dismantled, checked and re-built.
                              Re-bore and new piston.

        Suspension:  35mm forks from RZ Yamaha.
                              Monoshock replaced with adjustable, re-buildable unit.

Wheels & brakes:  Spoked wheels, alloy rims.
                              Front brake 2LS drum, rear brake 1LS drum.

             Electrics:  12volt conversion.
                             Asymmetric BMW GS model headlight.

       Composites:  Fuel tank.
                             Seat base (solo seat, with optional dual seat or cargo rack).
                             Front and rear guards (front guard mounted on fork lowers).

    Miscellaneous:  Flat handlebars.
                             Tunnel for original monoshock converted to oil reservoir.


These plans will undoubtedly be changed many times as the build unfolds.  Any ideas from the DTT community welcomed!

only saw the RZ now. you are mad.
but i recall you saying a 2 stroke project was due sooner or later and this is the one - very excited.
also interested in how the motogadget's M Unit goes for you. i wasn't aware that it even existed and this may well be the solution to what i was keen on avoiding.. do you know of anyone else here who has used the unit on DTT??

[stroker crazy]

smv - I'm pretty sure I've seen someone with an m-Unit on DTT but I don't remember who.

Are you back in OZ? I seem to remember that you were swanning about in SEA.

Swagger was using an M-Unit on his CB450 build.

You don't need the compression release, but, you have to wear real MX boots for starting.
Don't know what to tell you about the oil pump though?
 Maybe modify RD 350/400one for correct delivery amount?
