Quest Max 650 CDI BAD!

New member here. Hope I'm doing this right cause I sure need some help.

Bought a 2004 Bombardier Quest Max 650 with only 92 miles on it. Original owner told the guy I bought it from that he never used it much so when it lost spark, he put it in the back of his shop and forgot about it. I thought I scored a huge deal on an awesome machine.

Everything seems perfect except like the guy said, there's NO SPARK. Downloaded an awesome tech manual and started troubleshooting. From testing it and every other electrical component, I'm positive my CDI box is bad. Took it off and its been opened up and repaired before. Not sure when or who did that but it ticked me off when I found it. Oh well, just need to bite the bullet and buy a new one.

Here's the problem. Tried every local dealer around and they can't get one. Spent days searching the internet and I can't find a replacement anywhere.Can't even find one on Ebay. Called FullertonsPAC in Canada and they basically said its over 10 years old so Bombadier/Can Am don't produce replacements anymore.
I can't believe I have a like new machine that's un-useable because of a CDI box.Thought I'd get on the form and see if anyone could help.

MFG# 710000625-12370.
It says DENSO 071000-1840 on the actual CDI box.
4 pins on one connection, 6 on the other.

Anyone know where I can get a new or used one or maybe how to hack this one?
Any other CDI that might work with it?
Sure would appreciate some help. Thanks-

BRP trailing arm skid plate modification (pre 2017 design)

My BRP aluminum trailing arm skid plates were constantly bending and I'd get hung up on trail obstacles other quads were going through. I removed the guards and put the plastic cv boot protectors back on and immediately noticed I didn't get stuck anymore.

The aluminum guards are designed with a large "ear" that hangs down lower than the trailing arm. That ear acted as a scoop and the only function I saw for this extra part was to provide enough surface area for the Can-Am logo.

I took a leap and sawzalled my guards... sorry Can-Am, the logo was catching more than eyes...

I drilled a 3/8" hole at the intersection of my cuts to prevent stress fracturing and filed the edges smooth before I re-installed the guards.

So far I'm pleased with my results. Haven't gotten hung up in 50 miles of mud, snow and ruts filled with roots and broken ice.
