Hey Guys!! Appreciate any help I can get here.

So I have a 1980 cx500 cafe racer build. The air filter box has been removed and there's a filter on each carb like most cafe builds. I've had a tear in the right inlet for a few weeks now, so the bike has been spitting and coughing a lot. But yesterday I had a weird thing happen. Was riding along, I was in 2nd gear and then shifted to 1st. As soon as first gear engaged, the bike cut out instantly. It now won't start at all. The bike has always started very well. I noticed the tear in the inlet is now all the way around, so the air leak is huge.

Would this cause the bike to not start at all? Or does this sound like more of an electrical fault? I've ordered a new inlet so will find out soon. Any suggestions?

Joe

your post is 3 weeks old maybe you found a solution already-if not....as per Dave I'd suspect a CDI/coil/HT lead issue first
The term "doesnt start at all"-doesn't tell us a lot- does it turn over?? but not fire??-check your fuses too (under side cover is the main-might be relocate in a cafe tho)
BTW??how old is the fuel

bahn: That's 3 days old, not 3 weeks.

Joe: If the crack goes all the way through it might make the engine hard to start. You could try wrapping something like duct tape or electric tape around the crack to seal it temporarily and see if that helps.

BTW: Welcome to the forum. Please add your location to your profile and your bike's model and model year (NOT year first registered as your UK paperwork will indicate) to your signature so that you don't have to remember to tell us every time and we don't have to keep asking when you forget (see Forum Settings link in my signature).

And welcome to the world of antique vehicle ownership (they own us, not the other way around). Your bike is about 4 decades old and the Previous Owners may or may not have done the maintenance necessary to keep it safe & reliable (not to mention how well the "cafe" modifications were done and whether they sill have a negative impact) so it is highly recommended to download the Factory Shop Manual for your model (available through the CX Wiki - link in my signature) and go through all of the service procedures, regardless of whether your bike has reached the specified mileage.
I also recommend looking on all rubber parts with suspicion because rubber does not age gracefully. Check the date codes on your tires and replace them if they are over 5 years old no matter how good they look & feel because old rubber simply cannot flow around the irregularities in the asphalt well enough to grip, especially if it is cool or wet. If your bike still has the original rubber brake line(s) (should be replaced every 2 or 3 fluid changes = 5 or 6 years) I recommend shopping for modern stainless braided ones (they last practically forever and double the life of the fluid).
