Regal Raptor 250 : Loves LRP fuel, hates unleaded

[jape]

G'day TR. Pics and a bit more of an intro would be welcomed.

Is there no 'premium' fuel you could try? Higher octane? Lead basically coated the valve seats and shouldn't affect performance, I am not sure that is really the cause and fix - but as it works for you I am assuming it is the octane booster component doing the job not the lead!

You can get 'octane booster and valve saver' additive and a small bottle does 40 litres of fuel for $10 or thereabouts. I used it for ages in my old car and yes, it did make a difference, goodness knows why. No idea on brands in Turkey of course but Redex is a brand I remember in Europe.

If that fails its down to playing with carby, jets etc. in which case the mechanical types here need to know exact model and year engine variant you have. You might find more info. here already using Honda Rebel and other search tags. Try 'octane' search as well.

Thanks for the suggestions and thoughts... The normal unleaded here is 95 octane, but there is 97 too, and only slightly higher cost. Might be worth a try :) Personally I think it's just a mix thing, but canm't convince the mechanic here. He just says these models are just 'like that'... not a lot of help.

Hey Jape... What pics and info would help?

We would enjoy seeing and reading more of where you live and ride, and the bike at work of course. About you, not the problem!

Unleaded
Saw the word and thought I must be missing some neurons... I clearly remember Leaded fuel being phased out in the early 90's. Where could one still get leaded fuel
I didn't even bother to lookup LRP (Lead Replacement Petrol)...
Stumbled upon interesting finds on Leaded fuel, the early days..

"Ethyl" brand leaded gasoline -- tetra-ethyl lead -- loony gas -- one of the world's greatest environmental disasters. Many thousands died, and whole nations were poisoned. General Motors, Standard Oil and the Ethyl Corp. claimed there were no alternatives and that it was just the "price of progress." But there were alternatives.

"Ethyl" brand leaded gasoline versus ethyl alcohol -- which was the best anti-knock additive for gasoline? Three grams of tetra ethyl lead and 15 percent ethyl alcohol both improved a fuel's power. One was cheap, but it was a well known poison. The other was a clean, renewable fuel that helped farmers and kept nations independent of political oil pressures. Dozens of countries were already using ethyl alcohol fuels.
Just after World War I, American engineers made their choice. Putting profit above public health was nothing new for American industry, but it had never been done on such a massive scale and with such deadly results...
