Title: Fuel additive
Post by: neat street on August 28, 2017, 12:28:45 PM
Good morning all, do any of you use a fuel additive (leaded fuel additive) I am unsure whether to add some to my 1976 F1, or is it needed at all? If so, what would you recommend? would the newer fuels run hotter and possibly damage the exhaust seats?, the lead in the older fuels was also a lubricant I believe.
Thank you all in advance
John

Hi John, no need for a fuel additive, Honda designed the engine/seats to run on any fuel the bike was likely to encounter back in the 60's, luckily that means that they are able to cope with the ethanol laced rubbish that we are sold in the U.K. now.

No problem John, btw I have to admit that I still haven't gotten around to using the down pipes that you gave me to make the 4 into 4 system for my CR, but they are there, in the garage, waiting for that burst of energy required to start the job! 🙂.

Although I'm answering a question that was not asked.. whenever I know that the bike is not going to move for a while I add a fuel stabiliser to stop the hydroscopic ethanol separating from the petrol.

Yes it's not expensive and can potentially save a bit of grief, I use this
