Decided to use an MX/GYT expansion chamber with an 360MX silencer




We did run into some issues.... the rear brake stay needed to be refabricated as is would not fit the later style rear brake hub...also the upper rear motor mount is not compatable with the RT3 motor.

Here's the rear brake stay in midst of being fabricated



Here's the rear motor mount that we made shims out of steel stock and used a longer bolt....The mount is very solid with the new mods

Mission accomplished !!....

A fully functioning bike was built from a bare frame in less than one day !! Monster build successful..

I was not sure it could be done ?

A big thanks to DVM for his help today ... I could not have done it without your help. This is the first phase build..... more to come on the HUNGRY VALLEY DT1 SPECIAL...


For now its time to recheck all nuts bolts and assembly...then more mods to get her ready for H.V. 2011.

Stay Tuned...going to post a short video of the ride after the bike was completed today..

whew.... I am tired !

Now that the bike is together I have tried various pipes on the bike.....sleeper pipe...GYT/MX pipe....Bob Bailey (Torque Engineering) and none of them fit properly....So any pipe I decide to use I will need to modify a bit to make fit.

Since the motor is 2 inches lower now, it makes the pipes hit the frame in various places depending on which pipe I am trying to fit...

The sleeper pipe is the worst and would need lots of work to make it fit.
Sitting on the bike I can feel a big difference on the footpeg location...as the new frame the footpegs feel low....

My first order of business is to get a pipe fitted and mounted properly so the bike is rideable and then I can really check out the bike and new frame. I will need a spark arrestor on whatever pipe I use as it is required at Hungry Valley.

I will post photos of the pipe once I have it mounted properly..
not quite sure which one yet hmmmmmmm???????????

Default DT3 tank must go

Since the name of the build is "Hungry Valley DT1 Special" not DT3 Special..... the DT3 gas tank must to go ! My plan is to now make the bike look like a DT-1

Fortunately I have been saving this gas tank for a special project like this ! This tank is nice and solid..



Except for the dents on the right side

DVM and took a torch to it and pounded out the dents from the inside




Most importantly the inside is extremely clean... it was found sealed tight with old fuel in it. Took channel locks to remove the fuel cap. From what I understand this is good sign searching good old fuel tanks.. If they are found sealed it keeps moisture out.

Default Tires And Wheels

Hungry Valley has some sandy areas and the Kenda road tires will not work very well..... so off comes the soft smooth road tires and
and on goes new wheels mounted with Kenda 50/50 tires.



The Kenda 450 X 18 should work nice in the soft stuff...
