Well the main focus has been on the SS50 racebike, as this is the biggest technological challenge.
Over the winter, changes have been made, footpegs were moved back, fairing was added, tachometer was changed... and changed back again.
And then the season started and a lot more changes and tweaks were made.
-Because of the footpeg relocation, the front forks needed stiffening.
-The new mechanical tachometer couldn't keep up over 13k rpm, so the electronic unit was fitted again.
-The inner rotor ignitions weren't functioning correctly, so the old outer rotor battery ignition was refitted.
-The newly made 24mm carburettor turned out to be too small, so back to the 26mm
-The new 5speed dry clutch engine wasn't delivering what it should.
The dry clutch although looking and sounding cool, was a step back in handling, this combined with the last event in Gramsbergen, where I swapped the 5-speed motor (because of strange noises) for the old 4-speed before the second heat (which also developed some strange noises after that) meant that both motors were opened up fully and examined.
As it turns out, the 4-speed motor had a better cylinder head as i had been more cautious porting the other head.
So now a new engine has been built, with the 5-speed gearbox, wet clutch and cylinder head off the other engine, combining the best bits. In a small testrun it displayed 16k rpm on the tacho, while still pulling, so I'm looking forward to the next race, to see what it actually does.
Sick looking bike, thanks for the post.
ReplyDeleteYeah, thanks for sharing all of this stuff. Truly inspirational stuff. Your blog is probably the main reason I've decided to rebuild two old C70 Passports for my twin 9yr-old nephews. THEY certainly don't deserve it! Ha-ha. But yeah, seeing everything you've accomplished with these bikes, and how you're making copies of the true Unobtainium parts for 'em, it helps me to believe it'll be possible to do this on a decent budget. All that, AND your blog furthermore inspires me to do ever more RETRO-FRIED mods to my "CB900K0 Bol Bomber" - I'm making attempts anyway, at some proper '60s style rear-sets for it. I really do believe that if one were to reproduce some CR93, CB72/CB77 etc rear-set brackets to fit the CB750F/CB900F/CB1100F etc, that they'd sell like hot-cakes! If nothing else, it would be a very smart move, to mould copies of the CB1100R rear brake pedal, or better yet the 'R-bike's rear-sets entire, plus the Euro-type CB1100F sport-kit rear-set "LATTICE" peg brackets. Never mind the "WOMBAT" CB1100R finned generator cover. People pay through the nose for 'em, and it seems like everybody want's 'em on their 750's & 900's etc. So, if you're already doing some casting work like this, I'm just thinking this would be a way to fund all of the more INTERESTING stuff for the smaller bikes! That's what I'M interested in - I certainly don't want the lattice 'F type pegs on my bike, heck I've rid my bike of any & all references to the 'F series in the process of turning it into a previously unknown 'K type. Even so, I'm dead certain it would be a worthwhile endeavor. Of course, the list of Unobtainium parts which are in dire need of series reproduction? Is longer than your arm! There have got to be at least two or three parts per every model which Honda ever produced....
