What did you do to your Yamaha today?

Did it feel like a long lost dog showing up on you porch? Lol

 

Sort of like that.....

 

opened up my first set of hatachi carbs. bowls full of green gasoline, floats still moving
found the air jets had a cover over them may be the carbs are not original to the bike I thought this part was discontinued.
its an 83 XJ750 Maxim

 

Page 3-49 of your manual.

 

And you can't just install the rings. You have to measure and set the ring gaps before they go onto the pistons.

 

Did some paint. Still gotta clean the tank up from a little over spray BUT... for my paint job I'm digging it. No more home made camo tank

 

Ah yes the ring gap another item to the list a one or two day turn around for the rebuild is not looking like its going to happen. Back to square one.
Now I get to pull the rings off the pistons and then put them into the cylinders to measure the gap. Thanks for the reminder.
Any idea of a good set of ring compressors ? I have two but I am unable to work around the rods from the lower engine housing to the cylinder head

 

Just finished a quick how-to about installing rings. It is more involved that I realized, having assumed they came ready to install from the manufacturer. This is why I love this site. I learn something new all the time.

 

Yes, there is a sort of 'J-shaped" plate that is above the two air jets.

 

Finaly get the head back from wellding,now i can start reasembling every thing together.

 

Your fingers.
The bottom of the cylinders are chamfered so the rings can slide in.
You can also use a set of worm-screw hose clamps backed with strips cut from a cerial box.

 

Matti recommends front loops!

 

Went for a short ride today to take the gf her phone charger. As i turn onto the street hit a patch of gravel frontend slid and down i went. No real damage to me except a little road rash on my shoulder ( thank you helmet never ride with out one) and only real damage to the bike is i scratched up my right side yics cover that i spent so much time polishing. Still im lucky be careful everyone and watch out for gravel lol.

 

Be careful, and get a set of case guards. They show up on Ebay for between $60 and $100 (depending on style and condition) all day long.

 

Finally installed a new valve cover gasket with new grommets. Checked the valves and had to replace only one shim. Also, finally after 5 years I finally got that damn valve tool to work. For some reason it only works if I let the valve bucket move up about half way before installing the tool. But honestly, I think I still prefer the cable tie method. Sync'ed the carbs and took a nice ride. 8000 miles before the valve cover comes on again! Feels good.

 

Also, when I had the valve cover off for today I noticed for the first time ever a hole in the cover on the left intake corner and in the right exhaust corner with matching holes in the engine. In wood working dowels are used like that to make sure everything is matched up properly and I guess these could be the same things. However it doesn't look like anything has ever been in them. Any idea why they are there?

 

For the reason you think. There should be metal roll-pin looking dowels, but they aren't absolutely necessary.

 

I mostly went and did some lazy riding, with a short dirt excursion. This lake was nearly dry not too long ago. Now it's full.


The ride back sucked though. Winds came up from the south, so I was riding in a 30 MPH crosswind for 40 minutes.

 

I don't think any of the XJ engines use the locator pins (although there's no reason they couldn't use them....). I think their earliest appearance is in the FJ600 engines.

 

I investigated a new line of bike trailers:
