Default Bike Weak Spark won't spark

Hi Guys,

So, I've done a few things to my bike, I've adjusted the carbs checked compression, everything is good.

However, I can't get a visible spark. I replaced the wire and the plug cap. When I kick the bike over, and hold the plug in my hand, I can feel a week current, so I know I'm getting electric to the plug, however, I can't see the spark on the plug.

Any Ideas of what else could be the issue? I ordered an aftermarket coil that I will be putting on next (got it for a coupe bucks so I figured it wouldn't really be a huge waste if it didn't do the trick.)

Thanks in Advance!!!

Default New PLug

Yup, there is a brand new NGK in there. Do you know what the carb floats should be set at? 16 MM?

16mm should be right. i can probably come up with the stator resistance numbers if you have a multi meter. take off everything that grounds to the frame and clean the ground spot with emery cloth. do the same to the stator plate and mount under the flywheel rotor in the meantime.

Default cr 125 1990 gears

hi all
new to this hole thing and am really confused of how to post a comment or start a thread. i will state the problem i am having but some advice on how to correctly direct my questions would be a big help.

my problem is however-
i have a cr 125 1990, great bike spends half its life in my garage getting rebuilt, new seals, bearings etc still a great solid engine tho. but recently have lost 4 gear, it just began to slip and wouldn't engage. stripped it down and found that the centre and right gear forks are worn and has caused damage on the gears as its trying to force them into the gear. i cannot source the parts for a 1990 but there are lots of 1998 gear trans on the net for sale but would they fit? i mean they are all the same up to 1996 but don't know whether to take the chance.

thanks in advance folks

deff have the stator checked. As OSSA said, check all the grounds and clean them. Check all wires as well. sounds like a stator to me thou.
