I have recently bought myself an 03 172 Cup and noticed for the first time on Friday when it was on the rollers that it has a 6.8k rev limit.
With this being my third 1*2 Im fully aware that its supposed to rev to 7200 once fully warmed up but it never goes above the 6800 mark.
The search function tells me that it's the thermostat but I just wanted one final check before I go ahead and get it done.
Is the stat likely to be the problem? There are no other heating issues i.e overheating/underheating and the car warms up fairly quickly the same as the cabin heater.
Any help is appreciated.
