John, if you're still looking for DT1M specs I have an article listing hts x widths as follows

EX 39x46

Trans 51x31/17.5

In 100x45 (to bottom)
     (75 to top of port)

When I had a DT1M cylinder I measured as follows

Ex 36.5
Tr 51
In 99 bottom, 76.5 top

Italian (Moto Villa, Beta, SWM etc) / Did Roy East race an R/T450 Duc?

« on: May 12, 2018, 12:41:37 PM »

Question for the brains trust:

Doing some research for an article on the Duc R/T450 for the HMCCQ journal.
I have in mind that Roy East (or perhaps another Oz legend) raced an R/T450 in Sydney sometime - back in the day I think.

Anyone know if correct?

cheers

Honda / SL/TL125 gear selection problems

« on: February 17, 2017, 04:57:15 PM »

Bro has gear selection problems on his little Honda engines (SL & TL125s) - changes up OK but difficulty shifting down, especially selecting 3rd gear.

 Any Honda officiandos know if this is a common problem on these engines and what the fix is?
cheers

Yamaha / For RT1/Pre70 tragics

« on: October 22, 2015, 01:02:07 PM »

Gents,

I have the makings of a Pre70 RT1 project that it's time to sell. It would have originally been an RT2 probably.

There's a rolling chassis  with RT2 tank. No seat. Fr wheel is 21". Rims steel. Forks need rechroming. Shocks are shot.

Bottom end (crank, inner cases & gearbox intact), with RT1 non-reed cylinder, no piston. Head is probably RT2/3. No clutch or ignition covers


Bike is located in Toowoomba


There's also an orange plastic Yamaha replica tank, similar shape to DT1/RT1 which I may sell separately

And a couple of RT2/3 reed v/v cylinders & used pistons that may go separately

PM if interested
cheers

Kawasaki / Re: barn find

« on: July 10, 2015, 01:10:28 PM »

Kawasaki engine nos & frame nos didn't match in those days, tho they were usually close.

Most KX450s sold in Qld were sold as enduros. They didn't sell for MX so Brisk Sales used an F11 ignition, front wheel & speedo etc & converted them. Still used the KX450's downpipe tho. Before the ADR rules came in (75??) you could register them. A friend of mine who worked at the local Kaw shop in CQ had one registered & rode it everywhere. He loved it. Still had it last time I talked to him.
