Good looking bike!

Thanks all for the compliments, all the work done on the engine would not have been possible or as easy as it was without all the great wealth of knowledge here. Pretty sure I read every post on this forum that had to do with engine/trans/primary mods and was able to piece together something that fit "my bill"

Fantastic..I spent the past 20 minutes reading your work detail and viewing the pics..Do u have any plans for the brakes?  Any idea on man hours spent, researching, ordering, disassembly, etc...What a great blog for the rest of us..Thanks..GM

No plans for the brakes other than messing with them till I get it right, I have "arc'd" the shoes to the drums, spent time fine tuning the brake arms link to apply at the same time and have the heavy duty cable. Biggest issue is the drum is slightly out of round so I get a little pulsation when braking hard. Might call around to see if someone can turn the hub with the laced rim intact. The rear works very well and I'm able to use it in conjunction with the front for pretty effective balanced braking. Never kept track of time involved on everything, too much to the point of being "obsessed" probably

Good luck. I have the same issue with my front brake. The hub is slightly out of round. I'm in Chicagoland and have had no luck finding someone to turn my drum.

Yes I have a feeling I'll get the same results as you when calling around. I have given thought to somehow solidly mounting the axle/wheel assembly on a fabricated stand and perhaps using an improvised mounted cutter to cut the drum in minute increments as the wheel is rotated, just more backwoods, shade-tree mechanics

Pretty much done with all the modifications on this machine. Engine and drive train are dialed in, working beautifully. Suspension mods I've performed have resulted in a chassis that gets better and is confidence inspiring as the speeds go up. The only brake mods left are having the shoes relined in the near future, but as the brakes are now they are pretty decent, all things considered. One ride at a time as I work towards capturing some good video of this machine on some excellent motorcycle roads in the mountains of North Carolina. This run is on NC215 headed south from the Blue Ridge Parkway. Speeds up to 70mph at times. Plans are for more video of this bike, ridden like a sport bike, at even higher sustained speeds on some real gems in North Carolina and Georgia.

Nice ride video!
Lovely roads there!

 Wow! that thing sounds GREAT !   looks like new money too.

It appears the time has come to split my cases.  Recently, I began to hear a NEW NOISE coming out from my motor - sort of like humming, metal against metal rubbing with pitch perfectly synchronized with RPMs.  A friend tells me it's one of the bottom end bearings.  That's exactly what I also believed is the case.

Well, I am going to replace three bearings.  I read somewhere that it would be a good idea to use German FAG brand.  Where can I order them from?  Is it the only brand I should consider?

Thank you,
Andrew

We use FAG or NTN. NTN are a bit less expensive.
If you are in the US, we can get you some.

 Uneven spoke tension can place asymmetrical stresses on the hub /drum creating warp or run out.  You might consider getting the wheel trued and tensioned then sending it with the whole wheel assembly to a brake specialist for the fitment of modern shoes.

 Here's two shops I have not yet used but are highly regarded. Doubtless there are others.

Just saw this. Your bike sounds great! I was right there with you for every on/off throttle.
I liked your late apex riding style too; you where taking all the lines I would have .
Stay safe and enjoy!

So on Saturday I got the motor out and both halves of it are now apart.  The apparent noise I mentioned in my 2015.09.17 post was indeed due to NU 305 cage failure.  Now I need to remove the three original bearings.  On the drive side someone tells me to remove the seal first, then the 6305 and finally 305. On the timing side I am not sure yet how I am going to proceed. But I will do it somehow.
I would like to replace the original oil seals with some good quality ones.  Would anyone know of such equivalents?  I was trying to find something in Timken's catalog but I gave up.

Thank you.

This is what is left of the bearing cage.  Does anyone have any idea why did it fail?

[ace.cafe]

Heat the case half in an oven to about 300 degrees Fahrenheit, and drive the bearings out with a wood dowel rod and a hammer. They should come out very easily, or even maybe drop out when the case is heated like that.
Then, put the new cold bearing in while the case is still hot. It should drop right in.
