hello,
thanx for your positive feedback.
some more information and thoughts:
# the "old" egli frame has 62.5° rake and 120cm trail. this is good for long straight roads. I wanted to go for a more modern design. the bikes of today have ~ 65° and 90cm. the all new KTM RC08 has 67° rake!!
I gave my frame 65° rake and <90cm trail. this will be good for all the twisty roads waiting for us.
all tubes are as short as possible to give the max rigidity. the 34 mikuni fit pretty well, but I doubt if the OEM keihin fit the frame.
# according to the modernization I used a lot of titanium and carbon fibre to reduce overall weight of the bike. all the titanium parts saved 2kg, disappointing when compared to the costs. all I have learned during my long time playing with bikes: when you want to save weight radically, you have to omit all parts that are not essentially.
nevertheless, my goal is to stay under 160kg ready to start (without fuel). I prefere 10kg less more than 20hp more.
# doing the frame and swingarm, it was much more work than I expected! all the cutouts of the tubes to fit their counterparts (this determines the distortion after welding and cooling), fabricating all the small parts (mounts for dyna coils, oil cooler, oiltank, fuel tank, rear shocks, batt, frame pressure gauge,.....)
# this thread is for all to animate to try to do something similar by your own. its not easy, it is a lot of work, but it can be done. all you need is two hands (at least 4 fingers on each hand), a brain with more than 4 gyrus (one for eat and drink, one for sleep, one to always remember that the steering tube is in a right angle to the swingarm shaft, and one to switch on/off your welding machine), the will and patience.
# and yes, there are some machines which make life easier:
my milling machine (a bigger one is better):
my lathe (a smaller one does it the same):
a small and very cheap bandsaw for all the aluminium stuff:
again a bandsaw for the steeltubings (do not know the correct term):
my Messer Griesheim AC/DC TIG welder with watercooled welding torch:
and last but not least, most important of all, my Makita band sander:
at the moment I am doing the seat mounts including the wiring connectors which will be attached to the frame on the one hand, and on the other to the seat. putting the seat on the frame will give contact to the wires and the seat will have to be fixed with two Dzus fasteners only (this system is well known to modellers, that way the wings including connecotrs are attached to the fuselage).
