A new project, the abandoned xj650RJ

I just ordered a set of gauges and a compression test kit with adapters. Only thing missing is the shim tool.

 

After having used the tool for years, I used the zip-tie method this fall........I found out that it's a WHOLE lot quicker, and a whole lot easier.

Yeah, and it is impossible to crack the cam or the head with the zip-tie method.

What thread does describe that zip-tie method?

 

Here is a video about replacing valve shims:

My project has come to a long pause due to weather. It has ben raining all week and I do not have a garage, the company that is shipping my motorcycle for parts is delayed and working on it. I can't wait to get back to work.

 

Technical question for the gurus: What frames are the same as the Xj650 Seca? I am thinking about looking for a frame for the parts bike... wait am I already talking about a second bike?

 

All right, thank you!

 

It's the only frame for the bike. Doesn't share it.

That being said I may recomission the original project as the "dragon warrior" and later find a frame to get a stock 650RJ up and running.

On the bright side, I feel more confident taking the carbs apart totally knowing that i have another rack aseembled to use as reference.

 

PLUS I have a rack that I just went through, as extra reference...........
PLUS I have two more racks that came with my 650rj when I got it PLUS that carb rack is common to all of the other non YICS xj650's.

So..............you have NOTHING to fear.

As far as the frame idea...........that's what I'd do, too. Swap what you need, and then mothball the rest til a good-titled frame shows up, then build another!

Thanks a lot!

 

And.... done! I finally got the last valve shim and now all of the are within spec.

The next step is going to be to get the starter back on the engine and test compression. I am hoping to get that done tomorrow, I already have a battery fully charged waiting for the task.

UPDATE: today I email the shipper that is moving the parts bike for me. He had a family emergency and will not get to it until the end of the month... I will have to wait two more weeks but that is ok, I have plenty of things to do with all the parts I have on hand.

 

Now I am a bit puzzled. I closed the engine after getting all the valve shim clearances within specs, got the starter attached and tested compression. All numbers went down compared to the first test, They are all between 110 and 125 on the 750 engine. I will read and check what "normal" is.

Normal pressure should be 156 and the numbers seem quite a bit low, not sure if this is because the engine has not been used in a couple of years or it needs a major overhaul...

 

This is the 750 that I am currently hoping to get in the frame.

 

It is not unusual for a motor that has be sitting to show lower compression numbers.

With all cylinders in the 110-125 range. I would continue onward to get the engine in the bike, and running again. The compression numbers will most likely stabilize after a bit of running.

Thanks a lot for the input Ghost. That is what I was hoping for now that I have plenty of parts to get this bike up and running (and even a few spare electric components).

 

While you still have the engine out of the frame.

Pull the clutch to make sure the plates are not stuck together, and give them a good soak in fresh oil.

Is this a common problem? I guess this is relatively simple task..?

 

Wow ecologito! You're really coming along with things! Thanks again for the airbox link you sent me. I'm not sure if I'm going to get one or make my own, we'll see. I'm certainly getting some aircleaner joints from chacal today as soon as I get the quote.

So, what is your end goal for your bike? Keeping it stock or changing the look of it?

Best wishes bro!

 

I agree with MiGhost
