What did you do to your Yamaha today?

Started the install of a new fuel rail for the fuel injection. The original one sticks out a bit on the sides, but the new one should tuck under the tank nicely.



Also did some more work on the LED lighting conversion (custom flasher to keep self-cancel system with LED turn signals, and a mod to the computer so it won't complain about the tail lights).

Took apart instrument cluster(wouldn't say removed, as I just sort of spread it out to get inside it) replaced neutral light bulb, high beam indicator, cleaned instrument faces and lens, installed in-line fuel filter, but kind of screwed it up, think I need some more fuel line and get it in better position, treated scrap yard fuel tank with phosphoric acid to get rust out of inside, primed bottom of tank, still sanding top. Put headlight and instrument assembly back together and petcock and fuel level floaty switch thing back on tank. Uh, etc.

 

Finished installing the new fuel rail. Put the tank back on, hooked everything up, and ran the fuel pump a bit to pressurize the rail.... NO LEAKS!

Also rough-cut and base-painted the polycarbonate plastic I'm going to try to use to make new gauge faces for my instrument cluster.

If all goes well with the gauges it should be ride-able again by Friday... maybe even earlier.

 

Had a look at my new Colortune and decided that the time was right to try and get her ticking over better. I have been having issues with not idling too well and revving too high once warm.
I've been looking in the forums for days now, picking up the hints and tips from the rest of you guys. Phew! There's a lot of information in here.
I could really spend a whole day easy, 'just' looking at info on carbs and tuning.
Anyway, i checked the state of the plugs first..
Number 4 and 3 looked way too rich.

Number 1 and 2 looked ok? maybe a bit lean.

Anyway, i have adjusted the relevant settings and she is idling much better now. I need to take it out for a ride to see what the acceleration is like etc.
I'll let you know how i get on.
But really wanted to say that i only attempted to do this stuff to my bike after reading so much valuable information on this excellent site.
Thanks to all the contibutors that make it such a valuable resource of information.

 

Chaps,
Apologies, i just realised that the i tried to put some pics of my plugs in the last post (linked to my gallery) but that obviously didn't work. Guess i need to look up why. I also have some video of my Colortune (Need to know how to upload that one, or do i have to host it somewhere offine?

I finished the paint on my yamaha sport fairing now I just need to reassemble and install. That install part looks tricky I think I may need an extra hand to help hold things.

 

TORE ENGINE DOWN AND BEGAN REUBUILDING!!

 

I thought about my bike today didn,t do a thing to it all summer.Wonder if this topic will hit 100 pages?

 

well i can certainlety help. I hate my mufflers, want them to look nice so i took off the back caps, sanded down, repainted with black paint, heat resistant, and painted the bolts chrome looks pretty good imo, i have rust on the bottom of my mufflers, think about sanding that part down and painting it with that black paint.. will slow the rusting and u cant see it.

 

bought an LED light kit... half way installed and kinda workin on a how-to, any of you guys interested?

 

Lazy day. Just bled the brakes which was so much messier than I had planned. On the 750 seca's the cylinder is located in just about the worst place you can imagine on the bike. I had to remove the headlight bucket and it was still a nightmare. There was a 10 foot circle around my bike of brake fluid that I had tracked around lol. It's all good though. My brakes are not a concern now. Onto the next problem.....tomorrow.

 

Was a very busy weekend for my bike. I swapped out the 750, as I was having problems with 2nd gear not being there, for a 750 from a Seca. I am going to try a 4-1 exhaust, and see if I can get it to sit low enough for my saddle bags. If not, the 4-2 will be going back on.

Still need to bolt in the oil filter, fill 'er up with oil, and bolt up the drive shaft to the motor. Hopefully the weather is nice this week.

 

Today, I pulled apart the front end of the 750. Then I was able to get everything else off for the engine removal. I just need to rest a short while before I attempt to lug that motor out of the frame by myself. Basically the only things left on the frame is the wiring harness and swing arm (motor's just resting in there)

 

painted the bodywork of Maxim #2 after WORKS cleaning the inside of the tank and sealing it with REDKOTE...will make a link with pics

 

This....... :?

 

Cleaned up the rear hangers (that i bought from Fleabay). Sprayed them with matt exhaust high-temp paint (that's all i could find) Then i found some black gloss (Duplicolor) in the back of my cupboard. So, i sprayed it over the top of the matt...WOW...came out great (i'll try and post pics).
Also, cleaned the speedo cable (after noticing that it was going haywire). It was a bit gummed up at the bottom so i poured 3-in-1 down there until it came out the bottom (Yes, i read the "WD40 is evil" thread). Haven't tested it yet.
Last thing i did today was fabbed up a rear seat pad (out of some ply-wood and an old mud-guard from a suzuki motocrosser (long gone).
I've cut some 6" deep foam and glued it to the plywood (with carpet spray adhesive). Let's see how it turns out. ...Just remembered i need to get some vinyl to cover the seat pad.....off to fleabay again i guess.
(It's not gonna live permenantly on the bike, i'm gonna install it and leave it on for a few weeks).
The wife wants to go on the back...fortunately she loves bikes .

 

Started her up just to hear her run for a little bit. Didn't even take it off the center stand. *lol*
Covered her up before the cold front with rain arrived. That's it, I'm content for today.

 

Today:

I rebuilt both front forks.

The left fork was spitting oil out through the dust seal. Thus was extremely needed.

I have to mention one thing tho.....

I have torn apart many fork assemblies in the past. And the xj650 is by far the most difficult I've encountered. I'm not a huge fan of the upper plunger seal/circlip combination. Without the right tools (ie clamp and press), it makes the 650's fork rebuild a chore. I much prefer the 750's forks.

 

Yesterday i finished up the rear seat (pad). The vinyl arrived and i couldn't wait to get started. It looks really good (if i do say so myself). One thing tho i forgot to use adhesive before i stapled it. I also had to remove the first set of staples on one side because i hadn't stretched it enough. It's worth noting that the vinyl can really be stretched quite a lot.
The more you stretch it the better it fits. It's also waterproof.
So in the last week i have,
- Installed the newly restored rear pegs.
- Built and installed the rear seat pad.
- Re-tuned the carbs (still working on that)
- Got together a toolkit for the bike that i'm happy with (in my tool roll)
I will post pictures when i get around to taking the pics.
