Up on the table and had a good look today. Nice to work on something different. Nothing appears to be missing, except the throttle grip. “Borrowed” the battery from the CRF230F and it cranks nicely, once I figured out the clutch lever safety switch. The engine and gearbox are full of fresh clean oil and we have a spark. I’m going to check valve clearances next, before adding fuel.

Pulled off a few panels and fork guards. The forks aren’t  soaked, but they are “damp”.  Seals, dust seals, and fresh oil before long. So far seals, battery, grips, pads, and oil filters are all available on Amazon for next day at very reasonable prices. Amazing.

USD forks  I never had any of them open.
I imagine they ride Nice !
I wonder if they need a special tool to work on them ?

12+ inches of front fork travel
16 position adjustable compression and rebound damping
How many grandkids are gonna ride this?
I think You’re gonna learn a lot John.

Bill….. Yes some big wrenches for the top caps. About 50mm.

Kevin….. Chris’s son is going on longer and longer “adventures” with the CRF230F. Building this one so either he or I can tag along!

Set it up with a fresh battery yesterday and despite cranking nicely, NO SPARK. David had suggested he had it running ages ago, which I doubt. He included a new plug cap/coil unit that I swapped in with no success. Lots of “black boxes” on this bike, so I’ll start checking connectors and continuity next. This could be painful.

First check is the kill button...unplug it at the harness

Congrats, always fun getting a new toy.   Confused, you had spark and then no spark?

Steve….. I should have written “He had spark”. David said he ran it. Now I find that strange as I crank and see no spark. Got frustrated late yesterday, will have a fresh look today.

Got it.  Personally, I NEVER believe a seller...

Bad coil?

Clutch or kickstand safety switch ?

I jumped those out and nothing doing…..

I hope it's a continuity issue,rather than an expensive part.

I’m a bit out of my comfort zone. “Static resistance checks for the stator and pulse generator” next time I’m in the shop.

Getting frustrated! All the electrical components test as “OK”. Beginning to suspect the engine control box or the throttle position instrument. If I could convert this to a set of standard points, I would!

How much do they want for good,used ones ?

There’s a guy not far away that has two control boxes for $60 each, so not too bad. Tim (the fellow I race the LEXUS with) is a factory trained FORD mechanic and a real electronics wizard. I sent him a note inviting him (and his testing gear) over for a beer! I’ll start ordering bits after I hear what he concludes. I’m normally not this clueless but this one has me stumped.

I'm interested to find out what it is.
Does the start button turn the engine over and all the other things work:just no spark ?

[BenelliSEI]

I’ve jumpered out the clutch safety switch (no neutral switch) and dismantled the kill switch to make sure there are no internal faults. The starter button works as it should. The minimalist head and tail light are wired to only come on when the engine is running (no switch) so there is nothing else. I’ve confirmed grounds and power in every spot that should have them. Resistance tests for the stator and igniter are within spec. Tried three different coil/ spark caps. Mmmmm.?
