I know where there is a k3, complete with hm341s in decent shape for about that much

My k1 was $1100, I bought it running, but the previous owner had scrapped all the goodies and broken the unicorn triple clamp by forgetting the D washers

Buy it, flip it for more to fund your build.

The SKF bearings came in today. I have to say, I almost feel ripped off. $200 for the 11 bearings that go in the trans/engine cases and I don't feel like they're exactly the best quality bearings... I might order duplicates of everything from someone else and see if I've been had.

It's mighty hard to beat SKF bearings for quality! Check closely, though, the little grooves in the bearings to see if they are in the right spot, and the right width. The old JIS standard has given way to the ISO version for the off-the-shelf version of these same part numbers today, and they don't fit correctly on some of them, because of this issue. That siad, I know someone out there is grinding position-correct versions of these in SKF, as I have held some in my hand (they were not mine, sadly...).

Sounds like a steal on the K0. IMO K1 and earlier bikes should be kept as close to stock as possible. It's hard to find a K1 out here on the east coast and they're usually butchered or no title. Never understood how there can be so many bikes with no known history of title or ownership.

In any event, CycleX fork tubes are prices and sold as a pair. I recently got a pair for my K1 for about $150. I have Ikon rear shocks and am pleased with them. There were weld boogers in the threads I had to clean up upon receiving them, irritated me a bit for the price, but they handle nicely.

Cheers, Dunk. Thanks for the interest, mate. Stay tuned and you will see some really good stuff here in the next couple months. The 70 will be restored as stock as possible. My '73 CB750 has plans to be a Daytona CB750 Racing Type replica.
As far as the forks go, I'm going to use the overpriced RaceTech ones, I believe they're TNK or something to that effect.

Just from first glance, I think the grooves are too narrow... I should be able to put them in one of the lathes though and fix that pretty easily. My issues is that most of them don't spin like I think they should be able to. Unsurprisingly, the one Made in USA bearing that arrived is seemingly the best. One of the bearings came from Italy and the rest are marked Argentina on the outer races. All the boxes say SKF Explorer series.
My gripe is that they don't spin that well and that one or two actually spin off center/too much runout.
