Hi all, I recently changed my gears over to the 17 tooth bell clutch and 38t spur gear. Ran it for the first time and it had great top speed, very happy with it running on my local oval.
But after bout half a tank of fuel I noticed minor smoke coming from engine (around the cooling fins) so I turned off and rested it. After 30min I tried again, same thing happened.
I'm a little worried that changing the teeth may have changed something I'm unaware of. Do I need to re tune motor? It was great on standard tooth set up, only change is gearing.
The only other thing that I think it could be is that I cleaned the motor with a rag covered in Wd40 after changing gears over. It could be burning off that oil??
I have a thermometer does any one know what temperature it should be after half a tank flat out running???
Thanks guys, I'm a bit worried to run it without some further investigation.
