Thanks a lot - Barron.

I took magnifing glass and found no cracks in the soldier on the contacts.
I will take it to work, to the electronic lab.

Do you think that Techforlife will agree to take a look at it, and maybe to fix it ?

I think so, PM him, he's pretty good at fixing these things from what I hear.

Yup............PM me i`ll repair it........but if you have an "electronic lab" at work......you can easily resolder the board.......

There is a chance that the CDI is garbage....and resoldering will not help...out of about 50 CDI`s if had sent to me........3 were not repairable..

Wow.
This was fast.
Thanks a lot.

I will try to ask at work if they see something, and if they can't help I will PM you.

Thanks a lot, again, and have great day.

Failure points

Here`s the MAJOR failure points........there can be others,,but these are the ones to really look at carefully...

The blue spots are the worst by far..

The red are the next worst spots

The yellow spots are the next ones to look at..


Like i said these are the most common......but a really good magnifier is need to find them all.....i just remove all the solder now and do the whole board......








Here`s my repair thread at TT...

Great
(Actually, I got the idea to open the CDI from your post at TT, which I found while looking at the index of this thread :))

Question fifth

BTW: I saw in your signature that you have FMX650 fifth gear.
Why is that ?

(The NX second gear I know why)

Jetting

Maybe Mendo or CW or someone else could weigh in on my question. I rebuilt my engine last year with a JE 102mm piston and since then I have increased my main jet up to a 170 trying to eliminate the slight ping I get on the highway at 55-60 mph. Stock gearing and Daves mods done to the carb. The pinging occurs under a slight load like a heavy head wind or a slight uphill.

I have not checked the plug yet, but I tried a 160, 165, and then the 170 main with a slight improvement I think.

I believe what Mendo was experiencing was a ping at lesser throttle than what I am hearing at the upper range around 3/4 to WOT.

What's your cam specs? Jetting won't eliminate the ping ping by its self.

The FMX fifth is taller,,,,,,,,,,think overdrive.........

Right now with all the engine work and FMX650 fifth.....i can go down the road at 55mph and just barely give any throttle,,basically apply enough throttle to tighten the cables and a little more...

Anything under 50 mph with 14/45 gearing and it lugs badly though,,chain slaps horribly.......

Lower rpm at highway speeds is what i was after...
