Lead replacement additive, or not?
« on: March 22, 2010, 05:20:11 PM »
Are you using a lead additive or not (as I have read the threads about it distorting the carb diaphragms)?

Secondly, should we be running 'regular' unleaded petrol (95 RON) or 'Super Unleaded' (97+ RON)?

I use 87 octane, can't quite remember what that translates into, on your octane rating system .

I need to use mid-grade or premium once the temperatures start to get around 100 F. (38C), or the bike detonates on heavy throttle use .

Never used an additive and also never yet detected any measurable closing of the exhaust valve clearances. Early days though in terms of mileage.  I do retard the ignition by 2 Deg. to keep the pinging at bay.

I think the whole issue was overblown some when unleaded first came in.

This is just an observation from about the last 30 years or so .

Reading all of the articles in auto and bike magazines regarding comparison tests for after market fuel additives, and what ever is the newest hyped product of the time .

The usual conclusion, is that there is no real world data to back up claims of any better performance, or whatever positive benefit this product would have .

Most variations of the test results, were within the statistical error for such a test .

If there were any repeatable positive results, it usually was of such a small amount, that it wasn't worth the effort and expense .

Just the observation from another of life's  slackers .
