5 mil deto ~ Yummy.

Yipper skipper. Here's what happens when:

you are in a hurry to ride :bigeyes:
you don't wait for your fancy ignition :bigeyes:
your carbs are too lean :bigeyes:
your compression is too high for your octane level :bigeyes:
you use crummy oil :bigeyes:

Ouch...sorry to see that.

I know it all too well, went from MSD total loss to modded stock with stator advanced, too much timing, too many rpms, etc.

Any damage to the cylinders?

 

[WaveDemon]

dude, I've been there. That sucks.

 

[wildman326]

I had a little damage to the cylinders, a couple of grooves that I could feel with my fingernail. The pistons were already at max clearance, so I ordered a couple of wisecos. They should be here on Thursday.

The deto was so bad that there was 0 (zero) compression on the rear cylinder.

MSD should be here this week and I'm having the pistons bored on Friday.

Anybody know how to use a timing light to time the motor?

 

[Matt_E]

Why not use the built-in MSD timing checker? It's got a timing LED on the brain.

 

[Frosty]

Ouch, that sucks!

 

[MADMAT]

Sorry to see that man. ZERO COMPRESSION?!? HOLY SHIZNITE!!

 

[ducesrwld]

i tried using a timing light on my 650 sx cause i tried eveything and couldn't get it to run. i tried using the timing light and it was off quiet a bit. later on i was told by a mechanic you have to run the motor about 3000 rpms to get the timing light to be accurate. so it makes sense that my timing was off when i was trying to crank it over but don't know if this has any truth to it, just what i was told.

i always use the timing led when i am setting up a msd total loss system

 

[Mile9c1]

0 compression? That sucks. Is the crank okay?

 

[onesojourner]

that really sucks. that pretty new motor... :doh:

 

[wildman326]

Crank seems ok.

MSD timing checker . . . I don't know . . . I need more info. I think I have to set up the static timing at something like 24.5 initial which I believe is about .170 inches before TDC.

I need all the parts on the bench ready to assemble and then I'll call someone who knows what's up . . .

I've hear that there may be 5 degrees timing difference depending on the msd ignition or flywheel . . .

Like I said I need more info.

 

[wildman326]

Pretty new motor . . .

Yeah, here's a few before pics.

 

[Matt_E]

Give Paul a call. He faxed me the entire manual for that same ignition before. Valuable info.
I believe there may be a five degree difference.

 

[wildman326]

Yeah. I've been talking to Paul almost daily. He's a life saver. I have the manual as well . . . just gotta get my poop in a pile.

Should have everything by Friday . . . test run Saturday or Sunday.
