What are the cons of using a fuel with a lower lube % (Byron Gen2 specific)? Was I right stepping up to the 25/11 for run in?
the difference is almost negligible but 9% pro runs a touch cooler (again almost negligible) and higher rpm's . i do notice that the tuning is very very close between the two also , a touch more torque with the race 11% .
one question , why dont you run 30% nitro ?
yes you were right in running in with higher lube fuel
