Hey man, I'd suggest taking your problem to the big thread and asking some of the pros there. I have a link to it on my website on the valuable links page. I think I've heard of a couple of guys that had bad CDI boxes, but I don't remember quite well enough to know who it was. Before you drop big bucks on anything, I'd try swapping one of the CDIs out of one of you other 230s since you have such a nice collection! If you don't have any good CDIs, eBay has a bunch of them starting at just over $20. Here's the link:
suzuki 230 cdi, great deals on eBay Motors, Electrical Components on eBay!
And here's the link to the big thread. Lots of helpful guys in there that would know more about this than me!
Thanks, and that truck I see on your profile here looks bad a$$, I'm going to have to check it out!
