Helping a friends son get his '74 CB450 running earlier today. A new battery got the bike to turn over with the starter but it didn't have a spark at the plugs, but they do spark when touching either of the blue coil wires directly to ground (points wires disconnected) using a jumper. I'm assuming that the insulators on each points set where the screw that secures the wire from the points to the coils has gone bad. I've never run in to this issue before and find it a little strange that it happened to both point sets though one set does have more resistance than the other. Have you ever run into this problem before??
Check the wires at the points. Make sure they have the insulators. Had a no spark issue on a 90. Tracked it down to the insulating washer. What’s odd is it’s in both.
@@motorcyclerewind The bike runs now!! After I got replacement points that looked exactly like the old ones with a redish silicone looking insulator, I tested the old ones on the bench and they had continuity at all times, opened or closed. I see some points on Ebay that have plastic insulators, similar to other points I have in other bikes. I think get a set of those in case these fail later. Thanks for responding!
Shop full of dreams there, brother. Test light and a good multi meter. Good to go. Test rigs are always interesting.
Thanks for watching.
Another great video. Yesterday live was great too. Thank you again.
Thanks Michael, I really appreciate it.
11:04 For some reason I love that bubble popping noise. Reminds me of the Willy Wonka Wonkamobile 🤣 Love that Bike 💙 Thanks for sharing!!

cheack the cap for resistance.
Great tip.
It’s the points it’s always the points or coil what else is there?
You are so right. Thanks for watching.
Any chance you have a 360 scrambler exhaust? even just the headers?
