99 RMK 700 2 issues

Hey guys like alot of people I had problems with the voltage regulator on my 99 RMK. I put a new one on and all has been fine. EXCEPT after a few rides noticed that my speedometer along with my odometer (which is obviously on that same guage) and the lights on that guage dont work now. I dont really know what to check to be honest. Ideas?

Also sled ran great when i bought it and still runs pretty decent although at WOT it wants to kinda cut out. I changed the plugs thinking it was them because they were old but it helped nothing. Dirty carbs? New top end rebuild instore? Maybe just run better gas? Ive been running midgrade from Chevron mostly.

thanks for any help guys

Thanks guys. Sounds like I just need to pull and clean the carbs.

As for the speedometer guage, its just weird that the whole gauge doesnt work including lights and the speedo and the odometer. Ill look for a broken cable though
