When to run Higher Octane & Best Fuel Mixture

[jkross]

I just bought my first Banshee - a '99 that was alledgedly rebuilt from the ground up in 2002. Not EXACTLY sure what all has been done to it...The seller claimed the motor was built in 2002 by a race shop in Oregon - WhiteKnuckleRacing - I have some receipts. However, from all the receipts, all I know for CERTAIN, is that it has a "mild port," and a shaved head. There is no airbox - only two K&N, clamp-on filters clamped directly to the carbs. The whole motor is polished - it looks really nice. I don't want to screw it up and I don't trust the guy I bought it from to tell me what to run in it...he only had it a few months and didn't ride it hardly at all - said it was too fast for him.

 

My questions:

 

1. When do you HAVE to run higher octane or race gas? Do the over-the-counter schucks-type octane boosters work? How do I know that I need to run????

 

2. What oil mixure should I use? I need to know the ratio and what the best brand is. I hear synthetic may not provide the best protection - but that the "Castor" bean oil provides the best protection. Too much conflicting info - so I thought I'd ask you all - the ones actually doing the riding.

 

Any advice would be greatly appreciated. Thank you all in advance.

Most people run 32:1 or 40:1. Personaly I run 32:1. A little more oil never hurt anything.

 

I also recomend running a Klotz Oil. I use Klotz Supertechniplate. It is a synthetic oil that has 20% Klotz Benol Caster oil in it.

 

Here is some info on popular oils.

 

 

Klotz R50

Flash point = 400 deg F.

Viscosity of 18 cSt at 100 deg C. or 950 SUS at 100 deg F. (Approx. 50 Weight Oil)

Klotz Supertechniplate

Flash point = 460 deg F.

Viscosity = 200 cSt at 40 deg C. or 950 SUS at 100 deg F. (Approx. 50 Weight Oil)

Klotz Benol

Flash Point = 520 deg F.

Viscosity = 220 cSt at 40 deg C. or 950 - 1100 Sus at 100 deg F. (Approx 50 Weight Oil)

Amsoil Saber (100:1 recomended by them not me)

Flash Point = 237 deg F

Viscosity = 99 cSt at 40 deg C. or 13.5 cSt at 100 deg C.

Amsoil Domintator

Flash Point = 198 deg F

Viscosity = 40.9 cSt at 40 deg C. or 7.6 cSt at 100 deg C.

Amsoil Interceptor

Flash Point = 183 deg F.

Viscosity = 40.9 cSt at 40 deg C. or 8.0 cSt at 100 deg C.

Well might as will add Maxima Oil to the list.

 

Maxima Castor 927

Flash Point = 420 deg F.

Viscosity = 133.1 cSt at 40 deg C. or 13.79 cSt at 100 deg C.

Viscosity = 617 SUS at 100 deg F.

Maxima 927 Castor LINK

 

Maxima Formula K2

Flash Point = 240 deg F.

Viscosity = 97.0 cSt at 40 deg C. or 13.58 cSt at 100 deg C.

Viscosity = 450 SUS at 100 deg F.

I am not a rocket scientist but to me thicker oil that burns at a higher temp = better protection.

 

I run Klotz Supertechniplate synthetic oil bleneded 20% with there benol racing castor oil. It smokes some but not as much as yamaha lube. If you want no smoke or very little try the Klotz R50. It is 100% synthetic. I think next time I am going to try Klotz Benol. It offers the most protection but it is a castor oil and it burns a little dirtier than the others.

Well first off welcome to the HQ............. :beer:

 

As far as octane Yamaha recomends runnin' at least 93 octane in your quad, and if you do a compression check and you are above 160 psi, you need to run AV100LL (ie aviation fuel) or race gas. The higher the pressure the higher the octane you should run to keep the motor from detonating (ie pinging).

 

Most people on here run 32:1 with no problems, and yes everyone has there fave's, but just get a good brand Motul, Castor, Klotz, H1R, take your pick and stick to it. Don't change around because a different brand was on sale that day............

 

Others will chime in here with their .02, so take the advice and figure out what you want to do. Welcome to the money pit from hell by the way (Go fast goodies, you'll never have enough power )

^^^^what he said^^^^ . as far as octane rating and what to run..... the octane is your choice. There aren't any specific octane to run for a specific event. I run 91 octane for everything I do, MX, dune riding, pissing off the neighbors riding up and down the street, etc. The more motor mods you do the higher octane you can go Otherwise 91 octane should do. Congrats on the new shee.

Great advice from All - Thank you for taking the time to respond. I really apprecaite it! I'll err on the side of the higher ratio - I'm not the most mechanical person in the world - I'd hate to have to rebuilt it...but I guess I'll have to learn how someday

 

Thanks, again.
