Just thought I might pass this one of a kind R build on to you guys to hash over...
The fellow who runs 3ww is doing a Rotax 800 cylinder onto a 250r! He is currently working on the pipe. Very cool idea if you ask me... I have had one of those sleds and that motor runs quite strong. I am anxiously awaiting first fire up and test run on this thing! He has put many many hours of intensive machine work, welding and whatnot into this conversion..
I just think it is amazing the skills and ability some folks have.. Were it not for guys like this back in the day, we wouldn't have the hot rod big bores we enjoy today
It's a bit of a long read (14 pages now) but there is some interesting stuff there...
Here is a link to the thread... I'll beg pardon and remove this post if posting a link to another forums is against the rules.. Just let me know...
