What did you do to your Yamaha today?

Yeah, I'm with you... the problem is the idle screw is already backed out all the way, to the point that the throttle cable cam isn't even touching it.

 

sounds like the throttle cable is not adjusted properly maybe needs lube and check the routing of the cable

 

This—

 

Snowing in the morning… Mowing in the afternoon

Got to love Central New York weather!!!

 

Brrr, we had almost 90 here yesterday...strange for this time of yr.

 

ya ya ya my weather was like daves without the snow

 

Wrestled a new rear tire on. Tomorrow will get it balanced.

 

Checked my break lines, 1985 oops... Ordered a master cylinder rebuild kit and the copper washers. Found the stainless steel brake lines of my previous X so next week I can change the lines.

 

Shoei Seca got his cylinders filled with acetone/atf to see if the motor comes loose. It moves just a little, not locked solid. Fairing is off for evaluation. Carbs are off for a trip to church. The last registration sticker is from 1989.

 

Don’t muscle too much.....a stuck-open valve could give you trouble too

 

Got the rear wheel with new tire back on the bike. When I removed the old tire from the rim I noticed the rotation arrow was pointing the wrong way. Nice job to whoever mounted the old tire!

 

Finally got the carbs back on the bike and proceeded to run out a tank and a half of fuel. Cylinder #4 still doesn’t fire until warm it seems. Some vibrations at speed. Feels like holding a palm sander. Other than that it got a bit of a clean up and some needed miles.

 

The head is off, valves are visually "okay" for now, all closed with the cams out. Stuck problem is piston #3 must have had the exhaust valve open all those years of sitting and acquired enough moisture to rust stuck. Now sitting with Evap O Rust on it and will proceed to PB Blaster or Kroil if not more successful. Many moving parts are now 1 piece, brake bits for instance.

 

Evap O Rust converts rust i dont think it removes it.
acetone and atf will work mix it at 50/50 and let it soak may take a few applications but it does work

 

Acetone/ATF did next to nothing after several days soak. EOR helped more this time. I think the biggest influence was PB Blaster down the stud holes surrounding cylinder 3, they were well stuck too. Anyway the jugs are off now.

 

Have a new Yamaha and installed my 650seca mirror on it

 

I know it's a cooler, but if you look at the last picture real quickly, it looks like you have a boat engine on the back of the cart.....just in case

 

Trying to drill out a intake boot bolt. Yes swapping engine and noticed the boot was really in bad shape. I need to get some good high speed drill pits. Welding a bolt to it did not work, just broke it off further in the hole. Fun and games.

 

ahhhhhhh jeez, that's the worst. Best of luck with it!!

 

Took the seca for a spin to check the speedo works - it didn't so I removed the cable from the clock and rode it 200 yds - no spinning, so I need to sort the gearbox at the wheel - it was in the box of bits, so maybe it's bogaad.
Took the 650 maxim out for a spin around the countryside, got home cold with white fingers, nice though. The maxim with flat bars is a good ride on loose surface, loads of feedback when the rear spins up. Did some practice stops, it really does pull up well with the smaller front m/cylinder and Avon tyres. I get some vibration from the brake pedal though, so it needs a look in there.
