Bring Back Castrol R

[ruffdiamond 6,115]

I like the smell of grilled bacon,,, surely it would'nt be too difficult to bang a couple of rashers on the cylinder head before each race ,,, but maybe have to check that it would'nt offend any 'non bacon' folk first

Adding something to the fuel is of course against the rules! However, I know that many pros used to add either water or oil to the fuel to flatten the performance. Have used both synthetic and castor oils with little difference in performance or engine deterioration. Personal choice due to cost/sponsors etc. but with less smoke being emitted then I agree with earlier post that that's principal reason for lack of smell these days.

Why is Castrol R so attractive to the human brain? Creosote is another one.

 

I don't think it's related to memories of speedway perse...the actual aroma itself is very appealing.

 

Never understood why....

I am not keen on the smell of creosote, but do like the smell of castor, however, sometimes and according to my nostrils, in a concentrated form, i.e. lots of bikes chucking it out, it can smell like excrement!

Remember the days when riders added nitro to the fuel to enhance engine performance before it was banned.

Was this the reason John Louis was disqualified from the British Nordic Final in 1973? I can remember JL being disqualified after getting enough points to qualify for the next round, but can't remember the exact reason now. Always thought 1973 could've been his best year in the World Championship.

Apparently John bought a supply of what he thought to be pure methanol but during the British Final it was found to contain an additive - propylene oxide. He was cleared but whilst warming up prior to the European Final the FIM over-turned the verdict and he was withdrawn from the meeting at the 11th hour!

 

After the 1971 World Final the Russian rider, Vladimir Gordeev, had his points deducted (he managed to score 11) because, by then, nitro had been banned at FIM meetings and his fuel was found to contain the additive. Riders still continued to use nitro (highly volatile mixture) at domestic level and I recall that Garry Middleton once accused Ivan Mauger of using nitro at the 1972 (?) Will Internationale after it had been eventually banned.

 

Referring back to Vladimir it became somewhat of a speedway mystery that when he was banned (12 months) his brother, Valeri, suddenly appeared on the international scene. Western observers became somewhat suspicious assuming that it was the same person as they never appeared in a meeting together at the same time...hence the suspicion. I think that it wasn't until 1974 when they eventually appeared together that observers realised that they were indeed not the same person!

My son has always used castrol R and still does , when his engines go for service theres very little sign of wear , and no sign whatsoever of clogging . the oil gets thinner as it gets hot . and when it is replaced after 5 races its almost as clean as when it went in . the reason why some riders are using synthetic is the cost , with Castrol R now £15 a litre its an expensive game . Jawas need 500 ml for max 7 races £1.15 a race . Gms have 800ml capacity but still need to be chucked after 7 races , so thats nearer £2 a race .part of the reason for the lack of smell even when an engine is running Castrol R , is that modern engines have much better piston rign to Bore clearance , so all the oil gets scraped back down the bore to recycle . old japs had poor tiolerance so quite a bit of oil remained in bore and got burned . even a fully restored jap or jawa will smoke like a kipper and that smoke is the sweet smell of burning castor

 

Interesting stuff. Thanks for clarifying that Speedibee, I could well have been misinformed or my memory is as foggy as a fully restored JAP!

Notro would not work these days . for it to be effective over methanol the exhaust volume needs to be larger . open pipes no bother . with silencer attached the engine would stifle on back pressure and burned gas

i'm opening myself up to ridicule by saying this but its true -all the things i loved about a night at the speedway are just about gone:deep tracks, wide bars, gleaming bikes with proper mudguards, noise, black leathers, hardly any guests, local riders. I'm sorry - criticise me all you want but thats how i feel. Its likely that several thousand absentees feel the same

I have seen people using Smith and allen .castor . in fact i think Cov Comp sell it on their spares van . no doubt it's every bit as good as castrol . but I'm not convinced enough to risk finding out , there are quite a few others make racing castor , Beeline, rock oil , Putoline , and redline to name just a few , all are similarly priced . something for half of that price arouses my suspicion I'm afraid

Not sure about Notro, but Nitro still works well.........

Notro Damus , signals the end of your engine years before it happens

We use Castrol / Morris R in my son's Jawa and GM on Grasstrack, and in my Pre-75 Jap however it doesn't smell the same to me as back in the 70s. Maybe we build up a tolerance to the smell over the years ? Or as we get older does our sense of smell deteriorate like eyesight and hearing ?

certain times of year , early and late when the evenings are damp the smell seems to be more prevelant . but I think there maybe some truth in what you say . In an envirnment where you are subject to regular and large lungfulls ,a degree of immunity does occur

Maybe you bumped into a fencer and it reminds you of her perfume
