What did you do to your Yamaha today?

hmmm, what did i do to my xj900 today? wiped brake fluid off the entire bike due to a front master cylinder that decided to start leaking mid ride

on the plus side, it gives me an excuse to put the R1 master cyl on in its place!

 

Stop teasing us 750R guys. ;-)

 

:lol: i'll report back when its done

 

bought a brand new Hyosung master cylinder instead of an unknown quality used R1 master cyl. almost the same price - and bike stops real good now

 

Disassembled for some final painting, and rear brakes.... did the throttle shaft seals last night. Hopefully gonna put the rack back together + bench sync tonightt

 

New front brakes and rear brake shoes!

 

Assembled my homemade manometer and synced the carbs. They were very close, just a little tweaking needed since I bench synced them while I had them off. Put the tank and beauty trim back on and went for a short ride to make sure everything was working as it should. Finally the bike idles and has the throttle response again that it had when I first bought it! Looking forward to tomorrow afternoon so I can put some miles on.

 

Took it to the tire shop and got the new Dunlap 501's installed.

Also enriched the warm up curve a bit and switched (again) back to just TPS accel enrichment. The result feels darn near perfect.

 

Pulled the front calipers off to check the pads. Thought I was going to have to put new pads on the shopping list, sandpaper and brake parts cleaner instead.

 

Checked the calendar and realized i still have a roughly 22 day wait for exhaust to show up

Might take the 400 on a little back road drive tho

 

took the 900rk out for a ride yesterday, and everything was fine for about 5 mi, then started bogging and starving. I tried switching to reserve, prime, etc...........no help. Pulled the clutch in and she immediately died. I rolled into a driveway (turned out to be a driveway for a guy whose kid is into motocross as it turns out) and it would only turn over, no fire. WTF!!!! First day it's out in the spring!?!?!?!

So, I he and I just chatted and looked at all the trophies they had while I figured out how to get my truck and trailer.

Just for giggles I tried it again and it started right up. WTF!?!?!??!

Found the problem..............when you're out of gas, you're out of gas and nothing will go through even on prime until you lean the bike hard on the side stand and enough gas can get around to that side of the tank to get down to the carbs again. I bought a gal of gas from him and rode the last 1 mi to the gas station where I was heading in the first place. DUH!!!!! That's what I get for not filling it up n the fall. Note to self: If I ever do that again, kick myself!!!

No gas gauge on that model?

 

Took the 400 out for a 40 km ride. Ran like a dream, other than a possible weak battery (That's what I get for leaving it in the bike all winter)

 

First day out yesterday with new s/s hoses, calipers done, forks done, carbs cleaned, tank Caswell sealed, yada, yada. HUGE difference in the brakes, thanks for all the info and opinions on stainless vs rubber. I filled the tank, brought it home and this morning when I went into the garage I noticed fuel leaking from the overflow on carb 3...Arrrgh.

Off with the petcock that was not shutting off and I found if you are REALLY careful, you can separate these without having any spare parts. I polished the seat that the diaphragm "o" ring seats on. I used a liquid metal polish with a sharpened pencil wrapped in a blue paper shop towel. The sharp end of the pencil conforms perfectly with the tapered seat. It took very little "lapping" to mirror-polish the seat.

I think it failed because I had the petcock out all winter with no fuel in it. The fuel evaporated and left a brown cruddy deposit. Tested it with my vacuum pump, new Rotella 10-40 and filter, and I'm back on the road. I think a petcock kit will be part of my fall-winter Chacal parts order.

I also had a local (Ottawa) shop replace the blue and red decals on my fairing that were damaged by the PO. They look perfect, I wet sanded the fairing with 1000 wet and sprayed on two coats of Nason clear to seal everything. I'll post some photos after I receive my newly ordered Stebel 139dB horn. Hopefully it will fit into the spot vacated by the original horns.

Many thanks to all the posters and to Len for parts and assistance. Great forum!

The 900 Horn Circuit is not a Heavy Duty supply.

The Horn Button Closes the Circuit to Ground.

To avoid potential problems with the Horn Button,, ... Rig the Stebel Horn through a Relay.

Run +12V from the BATT to the RELAY --> LOAD IN
JUMPER --> +12 LOAD -To- +12V Relay Trigger Post.
Run +12V LOAD OUT -To- STEBEL +12V IN
HORN OUT to ---> GROUND.

RELAY Trigger GROUND Wire -To- 900 HORN Ground at Harness
Grounded when HORN Button Depressed.

 

Yeah, it has a gauge, but I was looking at miles,not gauges. There was only about 119 mi showing n the odo, so there should have been plenty of gas. I do recall now, putting it away with a note that I need to fill it up. Oh, well..... all's good now................. 'cept I gotta pay more attention to the IDIOT gauge since it appears that is starting to register things now....

Thanks Rick, the only thing that I can add to your list is a fuse on the supply side.

A relay is supposed to accompany the horn.

New steering head, swingarm & wheel bearings. Rebuilt forks with new seals. Rebuilt anti-dive units & speedo drive. Painted wheels. Rebuilt front brake calipers. Upgraded fuse block to blade style. New rear brake shoes. Cleaned & lubed all control cables. Oil & filter change. Checked & adjusted valves-3 new shims. Cleaned & rebuilt carbs-stage 3 dynojet, polished bores-clunk test, clear tube & bench synch. Had ignition probs-replaced coils & TCI unit & tested pickup coils. New spark plugs. Had headlight probs-did some re wiring. Added inline fuel filter. Today I finally got to ride with the bike running right & am very satisfied with the results. Many thanks to all here (too many to list) who helped me solve problems. You all have made a fellow XJ rider very happy. Hope I can contribute back sometime. XJ Bikes 4Ever!

 

Rode it. Yesterday too. And probably tomorrow.

 

Fully disassembled the carbs and boiled them in lemon juice. Waiting for a package in the mail (throttle shaft seals) to finish buttoning them all back up and re-check the float levels. Fingers crossed it finally runs like it should after all this!

 

Put 150 miles on it!

 

Hit the 500 mile mark (since I bought it) on my way home from work. Time to become more adventurous and take a few extended rides. Still gonna ride it to work everyday though.

 

bench sync... didn't get much time at all today...

 

tore the motor down on the 750 need new rings

 

JUST GLOAT ABOUT IT WHY DONT YA



>continues to wrench on alternator<

 

Tried learning a few new songs for the girlfriend on mine today.

 

hahah I own that guitar!
I installed new alternator brushes and crash bars...highway pegs to go on tomorrow!!!!

 

Rotated my handlebars down some. All wires and cables still have plenty of slack and nothing hits the gas tank at full turn.



Also converted tail/brake lights and gauge lights to LED.

 

Replaced a tail light bulb, lol, have left side blinkers again!

 

New tires.

 

Reset the cam chain tensioner, hoping it would fix a knocking noise

No luck, and I still can't figure out my stuttering issue -_-

 

Tested my 650R to see how waterproof it is. Nice hour ride in the cold, wind, and rain.

 

Looked at it....thought about it while I was at the all day baseball tournament with my son...then when we left the ball field the storms rolled in. Still storming as I write this. But tomorrow I am riding! Got my rain gear packed in the bags.

 

rode it 280 miles and then dropped it ten miles from home
:-(

 

I went to a vintage motorcycle salvage yard and got sick rear fender for my xj and a set of handlebars.Now i get to figure out how to mount the dang thing!

 

Started it after 8 months undercover. Water added to the battery cranked over on it's own and came to life. These are great bikes.

 

Pulled the plugs and checked the color, cleaned them up, changed the oil and rode the piss out of it. Met up with some friends and got to ride a Ninja 650r, lol, that was pretty cool! He rode the XJ 550 and now he wants one, said he loved the sound (like a ferrari he says, lol).

 

Well I'm going to ask the question we all want to know the answer to....
WHO WON?! LOL :twisted:


Dried her off and went for a short 10 mile spin. Longer ride tomorrow.

 

I think the 650 might have had me at top end, lol, but it sounded like shit doing it, so I'm still happy, he he!

 

Re-installed my tank, with its new paint job.

 

Painted my gas tank. Black with a small amount of blue metal flake in an attempt to match the original finish. It turned out much beteer than I anticipated, even though I used more metal flake than the factory did. I used base coat, clear coat . I will color sand and buff it in the morning.

 

Wellll, this has been going on for a while, but this is how it looked before and how it looks now.

Made up block off plates and got a bung for the filler, it's one of those that as you tighten it, it expands and seals:

Threw in a length of small link chain and shook it for a while, gonna rinse and then put the "Metal Rescue" to the test.
Also put some more time in on the header after, before:

Now my knees are F*****G killing me, so that's enough for now.

 

Rode the heck out of it in the neighborhood. It goes like hell though! Love the sound too.

Still needs one carb gasket made, headlight, and brake pads. Waiting on a "SealMate" to show up so I can fix the leaky fork seal problem (that caused the pads to go bad). Then it's register and insure time!

 

Pulled up beside a guy on a Big Dog Chopper at a stoplight. We looked each other's rides over and gave a thumbs up. The light turned green and we started off. I shifted to 2nd and kept my acceleration even and I heard him gun his throttle and shift to 3rd. I just kept mine in 2nd and stayed even with him until........you guessed it. I hit that magic 7K and smoked him to the next light. Of course I let off so as not to exceed the limit and he blew past me. What great fun!

 

Got it out of the garage... it started raining... put it back in the garage... went out on the VFR instead (easier to clean).

Nige

 

Decided that while it was stripped down I'd get out the WD 40 and start wiping away the years of accumulated grime, grease and crud off the frame. Got about an hours worth in before the smell of the WD got to me. Must say the frame and various components haven't looked this clean for quite some time.

 

Replaced the tail light and put new springs, bolts and washers on the clutch pressure plate.

 

Spent the past two days defying mother nature and riding it in the rain anyways.

 

Put it on the Optimate... ready for next (Bank Holiday) Monday... more later.

 

Well actually I did this Friday...
Picked up another quad of carbs via the bay.
I'll have to doll 'em up when they roll in But,
I just wanted an xtry to fall back on.
