This week, working on MP-250-A scooter. I replaced air filter under seat tray (where battery, fuses, ignition relay and CDI located) i had lawn tractor battery fit inside under seat (not in battery tray cuz its too big).. I forgot to bolt in side of tray. Tray fell out on one side and rubbed against rear tire and knocked off end of air filter. Air filter popped off, leaving 45 degree neck exposed.. I ordered new one with straight short necked cone filter (similiar to K&N filter but cheaper) for $10 from Ebay. Installed straight filter into Carb and repaired tray (forgot to bolt it in so I bolted it). After i did repair/replace, I rode scooter and its performance improved so much, no choking or suffocating for air in Carburetor while going 65mph or more on full throttle. I managed to get it to 75mph on flat highway (I rode on STATE and County highway, no Interstate "I-xxx"). Odd thing is that I noticed Speedo went 85+ mph and Tach show 7,500 RPM. I figured it was going 75mph not 85-90mph I followed cars in morning knowing they are travelling 70mph over 65mph limit. I was able to keep up traffic.
So I am suspicious that speedo isn't correct but Tach tells me otherwise. Is belt inside variator clutch slipping or wearing out? Just wonder. I guess that new filter have improved performance on engine and it runs stronger without suffocating or choking at high speed thus churns more torque on variator clutch which cause Speedo to go faster that actual speed. This scooter now have 3,200 miles on it.
(PS: Im planning to order correct size battery to fit in battery tray and put lawn tractor battery back to lawn tractor, my scooter body look beaten up but all lights, turnsignal, brake and everything on dash functions 100%. I bought it from my son for $50 )
