Topic: (Video): First ride after putting bike back together

Ok, here's the long-awaited moment!

nice pipe, nice bike.

Do you have some pictures about the bracket you made? And I'd love to hear that thing being revved.

[Tim2005]

That's sounding great. What running in approach are you using?

[jessezm]

I'm going to run it in the first 100 miles under 6-7k, short to medium bursts of loading up the engine on an incline (got a few hills on a nice 30 mile loop).  After I'm confident the rings are seated and it's not gonna be a smoker (first 30 miles and there's none at all), I'll increase the revs.  It's extremely hard to go anywhere at under 5k RPM because of the way the bike is geared.  It just begs to be around 7-9k.  But I'm going to resist that for a while...

I'll post up a longer video in a bit of the first start.  It's really loud when revving.  Almost too loud...

Felix, I'll try to get some pictures later of the bracket, though it'll be hard to see well since it's bolted on.

One bad thing so far--it's leaking a bit of oil around the base gasket on the outer left side.  I and really hoping it will seal up, we'll see after re-torquing, but that may be wishful thinking...

Bike looks great!

[jessezm]

Thanks!

Here's the longer video.  The smoke was just the assembly lube and whatnot burning off, it stopped smoking right after that.  Sounds like I revved it pretty high but I was keeping it at about 5k there...  She was skipping a little but that was just old fuel, which I drained afterwards and freshened up.

I'd keep idle revs well below that on a new donk...Ok when under load...but more stress at idle as I'm informed...
I'm glad you got past that car in the driveway - thought you were going to go over the hood for a moment..

[Robbnc]

Sounds good !

[kyre]

Sounds great! and loud! I know video never does the actual sound justice so I'm sure it sounds even better in person...

Looking and sounding good man.

I myself am of the older school way of breaking in a bike: ride the crap out of it. Used to be when a bike was rebuilt the standard op was to keep the revs high-get her ready for the life she's gonna live. Common though then was if you broke her in easy, you best kept easy.

That being said, do you have a build log? If so idots like me would like to read up on what you've done. I'd like to make the minor suggestion of adding a link to your signature?

Again man, great looking ride!

[bjatwood]

Sounds good !

Thanks!  I can hardly keep track of all the posts since I finished the build originally that detail the other work, but here is the original:

Since then I've had the motor apart a couple times--I snagged an oil ring the last time and ended up doing some other major work (well, to be fair, having it done...)  Had the carbs bored out, head ported, new valves and bronze guides, HD springs and alloy retainers.  Plus I rebuilt the front suspension with emulators and new race tech springs, and slapped some new Hagons on the back, and added a fork brace.  I really can't wait to really see what she'll do, but for now I'm trying to take it sort of easy... 

Gonna go another 60 miles tomorrow and see what gives with the oil leak at the base gasket.  I'll retorque the motor and I guess decide whether to pull it if the leak persists or gets worse.    And thanks, I'll change my signature!

+1 this is what I did with the CB810-K2. So far its paid off Have fun breaking it in!

I got my exhaust in the mail a week ago. Could you share some pictures of your bracket so I can get some inspiration for a bracket for mine? (Or steal the complete idea )

I'll try to get some pictures up this week, sorry, been busy!!!  Let me try to explain what I did, though:

I got a flat 1" piece of steel from the hardware store (aluminum seemed too soft to hold its form), and then simply found an object roughly the same diameter as the exhaust, clamped down a length of strap around the object and then hammered it out with a soft mallet until I had a mostly round piece with a long "tail."  Then I did some final cutting and shaping with an angle grinder, lined it up with the mounting point and drilled a hole.  It took some trial and error but I got it to work in all of about 30 minutes.  Then I painted it. 

The bracket does not close all the way around the pipe, however, and I think it would be better to close the loop completely and then bend a tab at the end which could form a clamp around the pipe.  I didn't really have the right tools for this but with some forethought I think I could rig something up.

I will do this over again and take my own suggestion above, as I'm not totally thrilled with my rushed job.  I really just wanted to get the bike on the road to test everything else out!  But next go-around, I'm going to make it clamp around the pipe, and I'm also going to dip it several times in rubber coating used for tool handles if I can find a product that can handle the high heat.  I painted the clamp so it wouldn't rust onto the pipe, but the paint job didn't hold well and it's already chipped.
