methanol vs 98/100 RON

[Freakshow]

So after all that do you still wanna do it ?  Swings and round about #27, but see where it takes you.

Speaking of methanol, are we still on for Nepean in 2 weeks Foss?
I can smell it already.

Me, EA and the Gally will be there for sure, Slides, organised some fresh methanol from me sprintcar mate, pick it up this week, fresh oil in the old girl and just gotta turn the rear tyre, see ya there !!!

BTW, Whisper said to say G'day to you, he was at Canberra on the weekend, still goes hard !!

Oh , yeah, seeing we are talkin about oil in this thread, I use Castrol Edge 25 w 50 in both bikes, blurb on Castrol's website says suitable for speedway motorcycle engines using methanol, as a single use oil

Interesting thats what i've been  thinking Foss, so that not a castor basejust a normal mineral oil

More info Foss have you used it in old Speedway bangers ? and is it safe you reckon for a 2 vavler ? and is it shit load cheaper then the price of castor ? its killing me, i even bought a collection tank to try to reuse the stuff later..

Freaky,
It is a castor/ synthetic blend, how-ever , it doesnt gum things up like Castrol R does after a while , but I dump it after the meeting as well as carb and fuel tank, part of post meeting maintaince, It does go milky if you over fuel your motor, ie way to rich, having said that, spoken to Sprintcar driver mate that runs the oil and Alky in the motor, he says the milkiness doesnt affect the oil and so does another GP midget driver mate of mine, and I have been running it for a while now and it hasn't affected my motors, Castrol Edge Sport 25w50 is a replacement for Castrol GP 50 which I used up until its replacement.
Check it out on Castrol's website.
I think it is cheaper than Shell M we use in TD's 84s, but my motors are Yammy 500s so was looking for an oil that suited recirculating oil systems
Foss

[Freakshow]

so....  QUESTION IS WOULD YOU TRY IT IN A 2 VALVE..

Special as its a one pass, it wont get the chance to go milky.  Web site says its mineral oil not blend castor

[JAP 454]

OK Freaky,
I did try to avoid giving an opinion, but, for what it's worth, with a 2 valve or a JAP I would stick with a tried and true oil like Shell M
Foss

[JAP 454]

Your right Freaksta, it is a mineral blend , got mixed up between Shell M and Castrol, I plead Insanity and a LONG day at the Skids yesdy, I'm still knackered from it !!

Foss

NOW after all that your sitting on the fence.  IF not why not given its non recirculating.  Someone somewhere must have tried it and figured it out by now.

Im happy to use castor but not at $15+ a litre unless its in a 2 smoker and being mixed.
Just to dump it on the ground ( total loss on the 4 banger) seem crazy and im going through shit loads ATM with PRac days and season starting up..... 

[JAP 454]

Have a yarn to the Tech boys at Castrol, I did, you are the only one who can decide which way to go, I guess.
but we are all traditionalists in many ways and reluctant to change, but $15 a litre hurts and to see it pumped on the ground nearly makes you weep !!
Foss

[Freakshow]

well the price can only go up from here as there is less and less market for it.

[suzuki27]

Thats great info guys. I reckon I will get the ports tidied up, up the compression a bit and try a 30-32mm carby. I remember talking to guy at the 2008 DT Nats in Canberra with a CR125 on methanol and he was telling me that he had a 2.6mm main jet in it. I know it had a GEM type reed block and a large carby hanging off it. It was fast but gearbox issues sidelined him that day.

[oldyzman]

Suzuki 27, have you raced dirttrack muck before? Cause if you havn't (like me) you will find it just as great a buz weather you use meth at the front pack or bang around with the middle of the pack running 98...
Brett

[Curly3]

I agree Brett, that's the intention/philosophy of just enjoying the experience.
BUT, there is a point you reach when you start thinking, now if I just tried this, I might beat that other bloke?
That's when the horn's come out of the forehead.

Kerry, Kerry, Kerry. Used oil back in your fresh motor - shame. Try turning the top end down after you have warmed her up. Just keep it on max into the bottom end.
