Good day forum!

After much deliberation I have finally mastered my demons and learned the error of my ways....
I was once a very happy 640E owner and member of this forum but was seduced by the dark side.... (4x4)

There is a link to some pics of my old beastie and I was wondering if anyone on here has seen her? maybe someone is still enjoying her? maybe she's for sale? :angel:

Im on the hunt for a winter tinkering project where the only criteria is a rotax motor and supermoto variety
I trust all are well and I hope to be back full time to this welcoming forum :drinks:

Cheers all
Tonka

Tonka 640

(i hope this works as I'm still a computer numpty....)

Hi Monty
Much loved it was I can assure you
Exhaust is large bore headers matched length, bored our head for larger dia stubbs and I so miss its wonderful noise!!
I was having a complete t**t moment when I let it go...
Time for another and not selling this time!
Nice to be back, thanks

The head and front pipes were originally from Malcolm (sportax's prior owner) it was from his hill climb race bike.
I can't remember the exact diameter but it had bigger valves, flowed, silly cam and head machined to take larger bore stubs, hence the large bore headers.
I had it dyno set up with the standard carb but was about to get a new mikuni and the problem arose...bike sold. So i never got its full potential, the pipe made a big difference, much more ready to rev, could have been the valves and head work helping too.
Ill dig out my old books to get the dyno reading and diameter of the stubbs.
I modded the front pipes to my old scorpion system and job done.
The more I think about it the more I want to hunt it down and get it back!
