The bad:

There appears to be an issue with the oil pump and/or oil supply lines.  At least one of the oil lines that supply two stroke oil to the crankcase show rather large air gaps in the oil. Upon further investigation, no oil was passing through the L check valve at the crankcase, and all of these parts of course are NLA.
Dont worry, the motor has been run with premixed fuel to properly run the motor, running time has been minimal and it killing me! I am dying to ride this bike!!

I posted a parts needed thread on the Triples forum and a member in Hawaii responded rather quickly, I asked to ship priority and just received them today.  However, the parts have been sitting and are untested, so I am not positive this is as easy as slapping the pump and oil lines in and go.

The problem with at least one of my oil lines is the check valve, it appears to be stuck - no oil passing through. And for some reason, Kw=awsaki made these unserviceable. Looking at my [disassembled] H1 motor in my garage, the earlier check valves were serviceable.  I'm looking for info on how to modify the existing line.
Here is a pic to compare the two lines, the serviable H1 line is on the top...

Steve, do you have an ultrasonic cleaner? I wonder if you could free up the check valve with solvents and possibly some application of compressed air .

But in any event, great milestone! It won’t be long now!

No ultrasonic cleaner, Nils.  I was shopping for one a couple months ago but never pulled the trigger [was going to use it for the bag of hardware that came with this bike]

Have to be very careful using compressed air, these check valves normally only see 4-6 psi.  My buddy has some type of old school tool that we are going to test these "new" lines with, headed to his shop tomorrow.

 You've been a busy little beaver on that thing.  Good that you are really taking your time and catching that stuff and doing it right. You soon will be rewarded with a terrifying ride    Anxious for the first report !

This bike has been a challenge from start to finish, and not yet finished!   But it has really been a learning experience, don't restore an H2!  (Joking)

My goal was to have a rider by Oct 1st, I missed it.  Our annual vintage bike show is next weekend, I really want to bring this bike, but only if it's done. Doubtful, at best. 

I can't wait to restore another CB, it will be a cake walk!!!

Stev-0 the HF ultrasonic cleaner is a useful item and it only costs 70$   or so...Larry

It sounds good. I hope you the issues sorted out and get it in the road soon. It's going to be a real stunner

Thanks Dave.  It's the little things that are frustrating, like not finding quality parts.  You've had similar issues with your builds. 

At least I'm not rushing to get a rider before winter settles in, it was still 90 degrees here today. 

[grcamna2]

I wonder if you could soak those check valves in a mild solvent for a bit and then tightly hook-up the inlet to a Safety Clean parts washing tank(they have high volume/low pressure pumps)and try blowing some fresh parts washing fluid through the line Stev-o ?

Quick update.....if you recall, I purchased a pump and oil lines from a Triples forum member in Hawaii.  He promptly shipped them, sent tracking info, and when I tracked the package, it went through USPS in Grand Rapids MI. WTF? 

Anyway, I received the parts yesterday, and all looked good...




So at lunchtime today, I stopped by my buddies shop, he had an idea to test the lines.  He had an old tool [Honda!] that he's used to pressure test engines.
We hooked the tool up to the lines, pumped the ball and around 3psi, the check valves released...woohoo!  So, I am very optimistic at this point but not super confident that this will be the last of the issues as this bike has been a roller coaster ride!!!

Here's the Honda tool...









BTW - if any of you have had Nils vapor blast parts for you, you'll know he always sends a treat when returning your parts.
Well, Mike in Hawaii does too!

 I've been buying stuff from the wrong people !  Those nuts look good. That is kind of strange your package for awhile was 45 miles to the north of me after coming out of Hawaii. Seem like LA or a west coast city would be the major hub. Hope it liked our fall colors

It was a screw up, he shipped it Priorty and expected delivery was Sat.   Tracking info indicated there was a delay, then USPS delivers it on Monday - a Federal Holiday.  Go figure....

Love getting a little surprise in parts box when they arrive.  Nils is one of the best!

Well, it is a foreign country after all. 

Here's the Honda tool...

That is old-school! Looks to be the same vintage as my sync rig.

Are those oil lines nylon?

Me too!   Other surprises I've received include a key chain and a Yoshi piston

Yes, I believe they are nylon.  I bet one of you guys can figure out how to repop these

You're in the home stretch.  You'll be rippin wheelies in no time!

Try and source some serviceable check valves you will need them

The check valves are pretty low pressure units to open at 3PSI.

I spoke to Darth [Jim] a couple weeks ago about my oil pump, he gave me good info on how to rebuild it [pretty basic].

I've posted on his KTOP oil lines thread, no response and another member mentioned he is currently not making them [he bought a custom truck with a blower and is playing with that]

[Stev-o]

Well, we have a rider!!!!   There is still a few minor little things that need to be done but once the "new" oil pump and lines were installed that issue seems to be resolved.  Bike starts right up and idles nice.  Only have done about 35 test miles so far, was out of town for five days [Florida].

First impression: this bike is fast!  I'm trying my best to keep it below 5K RPM for break-in...

[MoMo]

Looks good, congrats Steve...Larry

[tweakin]

Nice!  Congrats Steve o!

[innovativems]

Ah ya!!!  Looks killer!
