Rev Limit at 5,500 RPM

Something just occurred to me... these motorcycles use a waste spark system where there are 2 coils for the 4 spark plugs. Meaning that the coils fire twice as many times as needed for the number of cylinders. I wonder if changing the number of cylinders to 8 would make a difference?
I could be WAY off base here, but what could it hurt?

Thanks for the suggestion, but I can only adjust it for 1,2 and 4 cylinders.

After doing a lot more digging on this forum, and I think someone may have mentioned it on my thread, I think the problem is in my ECU. Since changing out the meter I had to install a magnetic speed sensor on the front wheel. That means that the original optical speed sensor on the back wheel is no longer in use. I’ve read something about the original speed sensor communicating with the original speedo and that speedo translating the speed back to the ECU to keep the bike from going over its 110mph limit. Since the original speed sensor is no linger communicating to the ECU there is likely a fail safe that keeps the bike from going above 5,000rpm, because at 5,000rpm in 6th gear (don’t have proof, only estimating) might take you past 110mph which the bike is not made to handle.

I think my only hope for using this aftermarket speedo is to have a local shop reflash my ECU to release that fail safe and maybe set a new parameter somehow. But, the likelihood of them doing that is very slim as that ends up being a liability for them by trusting me to not go over that 110mph cap with the rev limits removed.

I think my only options now are to 1) live with the 5,000rpm limit, 2) reinstall the original speedometer, or 3) find a speedometer that will be able to use the original speed sensor and will communicate with the ECU. I’m afraid option 2 is the most practical, but I can’t stand the way it looks with the modifications I’ve already done to the bike.
