What did you do to your Yamaha today?

I re-shimmed a bucket that I totally missed the first time (LOL). Fixed my fuel level indicator problem (no, I did not add fuel!), Replaced two HORRIBLE 'fuse holders' the PO had under the seat with weatherproof blade-fuse type. Put everything back together and rode this thing. MAN is this sweet! Sync and Tune is next...

My noise is gone (I fixed it d'oh) and the cover does NOT leak oil!!!

 

Got these little b******* out of their embedded state in the carb bowls..

 

Rode - in the darn rain - to my brother in laws - where I helped him schlepp a few pieces of furniture - rode home - still raining

 

Installed the front brakes after rebuilding, bled lines but now I have a soft brake handle. Worked great for 2 minutes then pulled in garage and went all most all the way to the grip. I am thinking I need to rebuild the master cylinder? I have bled it thoroughly. Any thoughts on this?

KH, your suspicions are probably correct, when you refurb one part of the system such as the cailpers, the other part, the MC becomes the weak link. The pressure wants to bleed back thru the cup on the MC piston.

 

Pulled all the valves and springs on the X head. I think I found the root of the reason why the engine had been removed from a bike in the first place. Turns out that most of the water passages are mostly to completely plugged with yellowish/greenish/brownish goop. Enough holes were open that the water could still somewhat circulate. My assumption is that the temp sensor couldn't detect that the engine was running too hot, it would start running rough, the owner assumed it to be shim=related so pulled the shims, found things to be relatively ok, or else found it to be too much work, pulled the shims and buttoned the top together again.

So, I'll clean the head, valves, etc......probably end up putting new stem seals in although these still seem to be perfectly fine, then lap the valves, and start re-assembling that.

I just got done resyncing mine...... smooth as silk!
But I din't ride today.... snow spitting outside today.

COME ON SUMMER!!!

 

I finally got to #1 carb of the rack that originally came with my bike, the float valve was stuck in the valve body. Here is a cautionary bit of info... don't soak your carb using W**mart carb cleaner if you want to re-use any of the rubber parts. I bought this carb cleaner from W**mart and it is not at all friendly to rubber. The float valve did get freed up though. I did, however, save the diaphram from harm, it was only exposed to the vapors. I did lose the choke valve grommet, the tip of the float valve, and the butterfly shaft seals. I knew this would happen, to some degree, but I have another rack of carbs that are in fine shape.

 

Today I cleaned up the stable a bit and started stripping the XJ down to the frame to ready for paint and polish.

 

If that carb cleaner ate those rubber parts, that means it was doing what it should.
Carb cleaner that works, generally eats rubber!

Be careful with your rubber parts!

 

Started priming carbs, centerstand, and swing arm for paint.
Removed 6 layers of paint from front fender...

 

Did NOT completely remove paint from left side side cover...
Turns out the sanding disc was too coarse, at 240 grit...

 

Well, I got the bike last summer. Came on here, introduced myself, showed a couple of pics of the bike as it came home to me, and disappeared.

Today, I started the tear down in earnest, pulled the carb rack to prepare for rebuild, and just for giggles, mocked up my new bars, grips and mirrors.

 

Today I dropped the rear spring preload and rebound dampening to the lowest settings. Doesn't seem to affect the handling with my 180lb carcass on it. Still trying to sort out a rear-end wobble. I checked the bearings, swing arm, and shocks. I'm guessing my rear tire is out of balance. And they just closed the Yamaha shop down the street. Obviously I didn't buy enough parts...

 

Filled her up with fresh gas and went for a ride, nothing to complain about after winterstorage.

 

It doesn't matter where you buy the carb cleaner. Walmart, Autozone, Advance Auto, it's the same. Been said a bazillion times on here, don't clean your carbs with the rubber bits in them or they will get destroyed.

 

What I did today:

Tested the waterproof-ness of the XJ. Shinko 712s have much better wet traction than the old tires.

 

melted your butterfly valve shaft seals? Can those seals be replaced? Are they available?

 

Yup. XJ4Ever
