do not put ANY additives into your bike ..

unless you have a hi-comp performance engine .. i wouldnt even use octane boost..just a waste of $$ and effort ..

99% of the oil/ fuel treatments are snake oil man .. that includes carb and FI cleaners ..

end of the day .,.. a m/c fuel system is easy enough to strip and clean manually

slick50 is sludge in a bottle

just go to Kumeu and stop at the BP with a can then.. or your friendly neighborhood small airport.. dirtbikes LOVE AVGas

EDIT: sorry .. assumed Auckland ..

there should be some places to get leaded hi-octane race gas in the "Naki

Ive been using 50/50 95 oct/av gas or 95 with octane additive and lead additive will these be ok?????

i run 50/50 leaded race gas and Mobile 98 on my FJ

....i have similar compression to you and it does a great job..( i wouldnt run it on cast pistons but if you have forged you should be ok).. check that the gas you are running is a 'fast-burn' fuel though

if you a have a bit of extra cash .. you can get some F&L SP-3 or S/T from Sedgin (http://www.staparts.co.nz/) auto parts in 5 gallon cans for about $140

The indepentant tests Iv'e seen show Amsoil to be the best too but
"Mobile 1 racing 4t" rated a very close second and is around half the price at $50 for 4 litres. I get it from Allied petrolium here in Hawkes bay. I think there are other allied outlets around the country.

should be ok if its been working for ya so far .. on your next teardown .. have a look at the valves and pistons ..they should tell the story

AMSOIL for motorcycles has been independantly tested against all the major brands (its the best)

It's $23 a bottle, buy some... :cool:

Does anyone have a link to these tests?

Just do a search on ''synthetic oil'' and you'll get half a dozen pages of Amsoil - they seem to have done some sort of scam there.....and that puts my back up for a start.Amsoil don't make oil,I think the base is Mobil,but it could be anything.Of course the quality of an oil is in the additive,which is what Amsoil is doing.I don't like the way Amsoil market their product.....but that doesn't mean there is anything wrong with the oil.

HOW BOUT JUST USING A QUALITY OIL AND NORMAL GAS

95 octane on its own just makes the bike run pretty average and detonates a little and i use motul 5100 10w40

DETONATING CAN BE FROM OTHER THINGS NOT JUST GAS LIKE CARBON DEPOSITS ,OR IGNITION TO ADVANCED , BP HAVE 98 OCTANE AT THE PUMP

My 7litre (429 cubic inch) V8 is 11:1 compression, it will only run any good on avgas or 98(and even then it's not as good as the old leaded super).

Cold plugs, ram-air and a richer mixture helped - but I still need 98+ octane.

SO YOUR 1920'S PUSHROD V8 PINGS , WTF HAS THAT GOT TO DO WITH A MODERN JAP SINGLE

Everything ya wanker - it's MADE from those old V8's.

And your 'recycled V8' into 'modern jap single' wouldn't be doing 125,000 miles + unless said V8 carried it on its deck!!

I think the single came before the V8. I could be wrong though... :dodge:

A JAPANESE motorbike single in 1917?

Mr. Peanut

I still dont see the connections between V8s and modern japanese singles. Would they not have evolved from previous motorcycle design?

Bah humbug ^_^

"I don't think so Tim"

Mr. N. Shimazu built what is generally considered to be the first motorcycle ever built in Japan in 1909

In 1912 MSA (Miyata Small Arms - odd that) supplied the Asahi (morning sun) single cylinder motorcycle of their own design and constructio n to the Tokyo Metropolitan Police Department.
It was a 3.5 (RAC) hp 4 stroke single.so, a 500cc. 480 yen it cost. A lot then
The Nihon powered by a 250cc cast iron single cylinder engine cost only 200 yen.

Sorry , Tim

EDIT: Incidentally, Meguro, the manufacturer who produced the Meguro K1 A10 "clone" a fabled wonder spoken of in hushed whispers in the 60s, first made motorcycles in 1909. Single cylinder ones.

Well I am riding a GSX 250 and have been puting 91 it as most of the time I am only commuting. Going to Bp and filling it with 98 is that going to cause problems or go better? would it need a bit of a tune for the difference or are these happy with anything you throw in them??

Mr. Peanut

19th October 2006, 21:00

If it can run on 91, running on 98 is likely to result in reduced performance.

Mr. Peanut

19th October 2006, 21:01

We should all be using Avgas anyway.

Ixion

19th October 2006, 21:17

It's leaded isn't it? Definatelt not in a BMW. And a two smoker is never going to need more than about 80 octane.

Mr. Peanut

19th October 2006, 21:46

Yes, it's leaded, with no legal maximum. Illegal for road use too.

I just like the price. Burn a litre, save 50c :)

Are you sure about the two stroker comment? Last time I checked the RS125 was running somewhere around 12:1

Ixion

19th October 2006, 21:52

Nominal 12:1. But effective compression ratio is always much much lower on a two smoker cos of the porting ('cept, maybe, I guess on something like a Bridgestone with disk valves).Though the addition of the oil in a petroil machine does drag the octane rating down quite a bit. And no hot exhaust valve to touch off detonation.

Mr. Peanut

19th October 2006, 22:01

RS 250 - 12.5:1 - How is it my NSR makes a comparable amount of power with a mere 7.4:1 ??

Motu

19th October 2006, 22:22

The Japs measure 2 stroke compression ratios from the exhaust port closing,the Euro's do it from bottom dead centre like a 4 stroke.Imagine 4 strokes measured that way - the Eso motor with 14:1 compression ratio has the exhaust valve opening 100deg BEFORE BDC.....it'd probably have a 4:1 compression ratio.
