Engine Trouble - intermittently won't start! Any ideas on what to look for?

[Roadsterryder]

If I had the air box out like you have it out, I would call Ron up and see if his shop has got an air box delete kit - it's worth every penny you'll have to pay for it! You will be able to throw that air box away and you'll have all kinds of room to work on your bike anytime you want. I did it to my 2012 when I did the plugs and wires, it was a good addition to my farkles.

Ron is out of stock for this Item also. I really don‘t like to spend the extra $285, especially when I can make this one myself. I am a retired toolmaker and I don‘t see a problem making one… but most likely I am going to put the OEM box back in place. Thanks for the advice.

Oh, by all means, if you have the tools I would in a heartbeat! I just couldn't see putting that air box back in the machine, and it gives you so much more room to work in the motor area, not to mention it will breathe better!!

Besides getting more space to work on the engine did you notice a performance increase?
Did your fuel milage change and how much louder is the engine?

It may be a little snappier on the throttle; mileage, I am not one of those types to check my mileage at each stop, I just adjust to my gas gauge. You will hear a lot more throttle body noise, which made me remember the days when we used to flip the tops on our air cleaners over, because we thought it gave us more air flow and horsepower!! It will have a throatier tone to its breathing! Not to mention the weight loss also, that things got to weight 25-30 lbs!!! Why they go from one side to the other just baffled the heck out of me!

Thanks for your reply.
I remember those days when we did all kinds of stuff to our 2 wheel bikes. Took silencers out of the exhaust of my Honda 750 and changed the air box for a better sound and believed we added more power…lol.
These days I like it more quiet when going for a ride. Still have the matching Can Am trailer for it that we used when we went to Maggie Valley and Lake George for a Can Am sponsored rally, but the trailer has been parked now for years. Most likely this is going to be the last year for us with the Spyder. Life changes and we have to adapt to it.
In the next few days I will look at everything again and close it up. If anyone has any more ideas on what I should look for while it’s still open I would greatly appreciate it.

Yesterday I closed up my Spyder and this morning I added fuel system cleaner and fresh gasoline to the tank and went out for a ride… fingers crossed.
The engine was running great.
While on the freeway, after 74 miles of driving, the engine just died. It was like someone turned off the ignition or hit the kill switch.
It's got to be something with the ignition. It was an instant stop.
While I was at the autoparts store yesterday, one of the guys said to check out the ignition coil. I tried to start the engine and it sounds just like it did before when it died. I did the full throttle thing and watched the gauges, on there is a signal from the Crank positioning sensor.
Now I will wait 15 to 30 minutes and try again. Hopefully I don’t get run over here.

If you crank the bike and it’s not starting, look at the rev counter. If it bumps a little to some small value of revs it means at least the crank position sensor is sending signals to the ECU and hence to the rev counter. Whether it’s the right signals, that’s another matter. My experience though with the little buggers is they either work faultlessly, work intermittently, or not at all. When they are working they generally are doing the right thing though. I’ve found even the most expensive engines in the most expensive vehicles still use cheap $25 parts.
