My apologies about the full mailbox. I wasn't aware. I'm not sure how to initiate a pm, so please try again now. Sorry for the hassle.
I have four service manuals... Clymer XJ550 & FJ600 Yamaha XJ550 R (H, J, K) (white cover) Yamaha XJ650G (gray cover) Yamaha XJ650G/H/J/K (white...
Last call on this bike. If I don't hear from anyone who is interested by the end of the day tomorrow (Monday), I'm going to give it to a friend of...
I've bought many bikes at this time of year for ridiculous prices from desperate or impatient sellers. I can't believe that I'm doing this myself,...
Interesting, thanks.
I'll have to take a look at the needle tips. I've never had trouble with rubber-tipped needles, but who knows...?
This is possible, I suppose, although I've polished that float pin and the bores on the float that receive it. I've also tried a different float...
Howdy- I have been away from this forum for a very long time. We moved to a new city in 2013 and I started a different job. I have had no time...
As previously stated, fuel flows just fine with petcock in the "prime" position. Bike runs great, in fact. That also eliminates blockage in the...
Diaphragm, plunger, spring all seated and operating properly...on both petcocks I tried, (see my second post). The fact that this behavior is...
UPDATE: I swapped a known working petcock from my other XJ650 and replaced the vacuum line. The problem persists. I've got an in-line fuel...
I have rebuilt a number of XJ fuel valves using Fitz's procedure, but this time I'm not having good luck. The petcock is from an '81 XJ650. It...
Always good advice to go back and re-read the adjustment procedure. My most recent adjustments were not done with the motor in the "C" position. I...
Just went through the procedure you described, Rick, but I think I made it worse. Not sure what to try next.
Thanks, O 'n B. It's definitely not a 550 tank. To be clear, I'm not trying to find a tank to fit a 650, I'm trying to i.d. the tank I have. It...
I've acquired a tank that I thought was from a 650 Maxim. It looks like a direct fit, and the shape of bottom of the tank is also a match....
I've got a leaky petcock on an '81 650 Maxim. I've done a partial "Fitz rebuild" on it - pretty much everything except replacing the diaphragm -...
OK, I got it! Thanks.
Do this with the tensioner "unlocked" then tighten it back down, is that what you're saying, Rick?
"Manual" chain tensioner reset? Is this something different than releasing the lock nut and holding screw, then retightening?
Valves are adjusted, everything reassembled, and the bike is running great. BUT... I'm hearing a little ticking that sounds to me like it could...
That doesn't really sound to me like a recommended procedure, Josh. Did one of the experienced people on this list suggest that you do that? I...
I put the tensioner back on and released the spring, but I didn't tighten it down until I'd turned the engine a few times. That took care of the...
I just removed the cam chain tension adjuster and the click I was hearing went away. There's still quite a bit of tension in the chain between the...
Thanks, Polock. So I'm closer on my second attempt... [img] [img] ...but still not dead on. When I took the sprockets off I was not able...
Thanks for all of the responses. One piece of info that I should have included above: The sprocket bolts are only finger tight. Not sure if that...
You may be right. I think I'll have to remove the sprockets to get enough slack to shift one tooth back (or forward, as the case may be). Not a...
First time reinstalling the cams after head removal. Following the factory service manual ('81 650 Maxim). The dots on the cams are close, but not...
Better to do this dry rather than with a Scotchbrite pad and penetrating oil or similar?
Good news from the machine shop: head and valves look fine! Got a couple of final questions before I order parts... 1) Clean top of pistons? Is...
I'm headed to the machine shop to get an opinion about the head and valves. Here's what I'm looking at... Cylinders 1&2 [img] [img]...
I went ahead and rotated the motor to gain access to those bolts, then made sure it was repositioned back at TDC before I took the last two bolts...
Hey, Rick. First time pulling a head as previously stated, so maybe I'm not understanding what you're saying. I'm following the factory manual...
I thought I wasn't supposed to rotate the cam shafts or motor once I got it to TDC.
Two thoughts on this matter: 1) The bike will be sold soon. 2) It runs so great that it really doesn't seem like it needs a valve job.
The two cam chain sprocket bolts in the upper position came out easily. I can't get the two lower ones to budge. I've used six different 10mm...
"Remove the four cam chain sprocket bolts." Uh...so what's the trick to get at the two lower bolts AND keep them from falling into the motor...
Thanks for the replies. Fitz, I did replace the doughnut washers when I did the valve cover gasket. A close inspection makes me confident that...
Meaning that they are hard to remove or break off?
OK, thanks, Rick. I do have the factory manual, but I thought I'd check to see if there were any special details not mentioned that I should be...
Greetings! Been a LONG winter and spring up here. So glad to finally be back in the shop working on some bikes. This is a first for me, though....
I finally was able to test the shifter with an assistant holding a power drill on the clutch basket nut while I held the output shaft and operated...
I hear what you're saying. However, the shifter has been acting like this the whole way along, even when that gear was seized on the shaft. It...
Any recommendation on color? (Just kidding.) Thanks.
OK, but that input shaft spins CCW. Got a suggestion for how to keep that nut from spinning off? Not sure where I would find a big nut and a small...
OK, now I'm confused. In the second sentence above, are you saying, "AND (your gears) aren't lining up"? And how do I create that drag? Should...
Sorry to keep this simmering but, because I have no real experience with shifters and transmissions, I'm really struggling with whether or not I...
That makes sense. I might actually be catching on... Thanks again.
Here's an update... The machinist I usually use said the axle was too small for his lathe and sent me to another independent shop. That guy...
On the other hand, I just figured out that both that axle and gear are also used on the YL2 and YL2C. I can actually buy a complete used...
