1985 Yamaha FZ750 - rebuild

[GateKeeper]

How hard would it be to get that Laser graphic off the can?I'm sorry but it looks bad.

Not really sure.....I might be able to take it out with a good stiff wire wheel on the end of a drill, and give the whole can a brushed looked....

or I might have to wrap it with a new piece of stainless steel, but if I was to do that I would look for some carbon fibre looking type of material instead....

or paint the can in black or silver or......

then again I figured I was going to be going so fast down the road no one was going to be able to read what it said anyways......

I will look into doing something about it......

Tins.....

Well my buddy Spyug is not one to disappoint.......

he has been working on my tins, and what a job he has done.....

here are some shots he just sent me.....

and it's looking good.........












now to get them, and put them on the bike.....

She is gonna be a looker for sure........

[GateKeeper]

NO Joy......

NO joy today, could not get her started, messed around all day, checked and rechecked everything and she just did not want to start, 12 volts at battery, 11 volts at the ignition switch and starter button, and 10 volts at the coils, something is not right, and I can't figure it out....

very weak and almost no spark......on any of the 4 plugs....

.

[psyguy]

Oh no, that must have been disappointing...

10 volts at the coils is no good... if you know the battery is good then maybe temporarily run a wire directly from the battery to the coils just so you can see if it starts with proper voltage?
I'd also double check the ground from the engine.

[GateKeeper]

Thanks for the suggestions.....
did the wire to the coils from the battery, no change
checked the ground, no change
snipped the ends of the leads, no change
checked the caps, no change
checked the switch, the start button etc,,,,,no change

so I have a bad wire in the harness, or a bad coil or both, bad TCI unit, can be a multitude of things

tried using the car battery as well

I am at a loss......

going back at it tomorrow.....and double check everything once again....

[GateKeeper]

I show no reading on any of the spark plug caps.....I took the apart the little resistor is good spring is good, brass screw is good, the little resistor show 9 ohms, but once I put it all back together meter shows 0, now that is boggling my mind

The BIKE IS RUNNING............

Capital letters allowed in this case. Congrats.
Spill it...what was it?

[GateKeeper]

4 bad spark plug caps.....all were showing 0 Ohms resistance......I had 4 other ones put them in and she started up after about 2 cranks.......

go figure......

[Nessism]

Four bad caps? Wow!

Where's the video? No video = didn't happen.

[GateKeeper]

had to go to work, I have video, and will try to post soon....probably tomorrow...

but ya all 4 caps, funny thing, when I pull them apart and check individual parts it showed OK, but once together,,,,,,no resistance....0 ohms.....

[GSX1000E]

Why not just go to a local NAPA (or similar) store and get some new crimp ends and boots to add to the existing wires and get a good connection?

[GateKeeper]

I had 4 other spark plug caps, tested them all showed 10 Ohms resistance, screwed them onto the leads, plugged them onto the spark plugs, all was good, cause she started right up......

I can look for other caps but don't really need to, these are working, a bit shorter than the original, but useable....

I checked online, new OEM ones, are 45 bucks each, WOW.....

I am just happy the bike is running, this small issue of caps I can now overcome somehow or another, or just use the ones that are now working...

now to order new tires, and a chain.....I will be on track for riding this bike for this season....

.

[GateKeeper]

first start up

Well, as I mentioned I got her running, and here comes the proof.....LOL

4 bad plug caps, changed for an old set I had, and she started up right away, Spyug and I spent the better part of the day before and we got no where, and never did get her running, but the beer was good, stogies were good, and so was the late lunch, so not a total loss....

so here we go....

.....i don't need no stinkin' airbox.
Surprised it runs that well without one, nice.
I like the raspy bark from the Laser.
