From the dyno runs I have done the amount of ignition retard is not a constant. The power loss with the temp gauge needle midway between the halfway and 3/4 mark is not as great as with the needle at the 3/4 mark.
If I forget to turn my fan on and the needle gets a bit past halfway I can feel the slight hesitation, but it is not as bad as with the needle at 3/4, it is very noticeable.
There is noway on these skoots to check ignition timing, there are no access ports to view timing marks while the engine is running.
Different temp thermostats will not work to alter coolnat temp once the stat is full open, as the coolant temp will still reach those high temps in traffic.
The 1700's are the first skoots that my ole memory can, uh, remember, that has an ignition retard programmed into the ecu based on engine temp.
