That K5 looks fantastic Ray, and it's great to see another classic CB750 brought back to life.
I love original bikes as much as I do "Hotrods", and if my bike was an almost complete bike I'd have probably restored it too, but it started as a bare frame with no swingarm that a guy gave me, that had been shoved under his house.
A friend of mine rang me from a swap meet to say he'd found a complete K6 engine for 100 bucks, so I bought that, and realising that I had pretty much all of the bits laying around my garage from my very expensive EBay habit, I decided to build a "Rat bike", which i completed over a couple of weekends.
While great fun to ride, the stock engine was a little underwhelming, so I did a full rebuild, with RC rods and Arias 836cc pistons, APE Studs, Mike Rieck stage 3 head, Megacycle 125/75 cam, etc etc.
The difference was awesome, I've no idea what the RWHP is, but I saw 120 MPH in 3rd gear @ 1100 RPM. (I didn't intend to rev it that hard, but we both survived, and I've done it a few times now) I decided to spruce it up a bit more, so it evolved into this:
Great fun, but trying to hang on at that speed with 2" over front forks, lowered rear and pullback 'bars was a scary experience, so I decided to go the other way, and stripped it right back to the bare frame, painted the frame with a nice glossy black Epoxy. My son Tim did the "Rainbow" paint job with some leftover candy paint I gave him, and I bought some rearsets and Laverda Jota 'bars, to make high speed riding a bit more comfortable.
All in all, it's been a great experience, and while I've built a couple of other bikes in recent years, this one is kind of special to me:
So, what does the future hold for this old beast? Well more power would always be nice, so I'm slowly working my way towards putting together my RC1060cc engine, with APE crank, undercut gears, Mikuni 33mm smoothbore carbs etc. Lots of work (and money, sadly) to go, but this bike will continue to evolve, and I'm really enjoying the ride. Cheers, Terry.
