I love'em as well. I've built a few over the years and I still have a couple underway now. In the past I've built:
* An XL 250 powered Maico
*XL 350 powered CZ.
*XL 350 powered Montesa King Scorpion/Cappra.
*Triumph 500 powered Bultaco M11 (Metisse). I also had a DT1 engine in that bike but it now is restored with the proper Bully engine.
*Triumph powered Cotton Cobra (now refitted with a Villiers engine)
*My DT1 from Hells frame is has the front half of an OSSA Stilleto frame grafted to the original Yamaha rear half.
I'm currently working on the Maico trials bike hybrid, Ducati powered Hindall and have a 650 Benelli engine destined for my Trackmaster flat tracker that originally held a Triumph engine.
Within the Klub Kevlar Network there is Edgar Phipps legendary 480cc XL powered Elsinore, his historic Triumph powered BSA (tribsa), Alan Jones' Yoshimura SL125 Honda powered Rickman Zundapp, and Peter Rowlands Yamaha MX250 powered Maico, all of which will be on display in the Kevlar Kompound at CD5.
Below is Jonseys trick little Yoshi SL125 Honda powered Rickman while under construction. It's now dripping in bling!
