Well if my memory serves me rightly, the Yamalube is in fact only semi-synthetic.
Personally I prefer fully synth.

Also, I would hazard a guess that Yamalube is just a re-branded version of someone else, that is charged at an extra 50% mark up due to label glued to the bottle.

Here are the oil ratings:
Although that guide I believe is specifically for cars. Not sure how it differs for bikes...

Yes, I think the Yamalube is just a semi. It is made by someone else to a fairly cheap formula, so it's nothing special.

Something like the Silkolene Comp 4 or Shell Advance Ultra would be a big upgrade over the Yamalube and if you use the code SAVE there is 20% off the site prices at the moment.

Hello Oilman!

I have a R125 2009 with K&N fitted.
This christmas I am changing the fork oil and placing stiffer springs because I have soft springs and a too heavy oil that results in low damping ability and it is bad. I weight about 90-95kg with gear.
Well what fork oil do you recommend me? Silkolene RFS fork oil 5w, 7.5w or 10w?
What about front brakes oil (I have a can of a special brake racing oil that costs a lot but it is too bad that it is already open for more than a year, it is clear like water TBH).
What about engine oil? Do I have to use only SJ (service manual) or can I use SJ and SL?

Thank you!
Best regards!

Hi

I would use the Pro RSF 5 fork oil

http://www.opieoils.co.uk/p-826-silkolene-pro-rsf-5-racing-suspension-fluid.aspx

5w is the standard viscosity and as you are using stiffer springs, it should work out better than the soft springs with thick oil.

The best fluids for the brakes and clutch are the Castrol SRF, Motul RBF660 and Gulf RF1000, but they are overkill for 99.9% of people. The Motul RBF600, Gulf RF1000, Millers 300 Plus and Fuchs Pro Race are close to those, but don't have quite as high boiling points. The next step down (in performance terms), but still an upgrade over standard are the Gulf Racing 5.1, Motul DOT 5.1 and Castrol React Performance. Any of the other DOT4 fluids we have are fine to use as a standard choice.

http://www.opieoils.co.uk/c-450-brake-fluid-clutch-fluid.aspx

According to my data, the engine only needs an SE as the basic option, so SJ or SL will be fine.

http://www.opieoils.co.uk/c-782-10w-40.aspx

The best oils there are the Silkolene Pro 4 and Comp 4, Motul 300v, Redline, Amsoil, Shell Advance Ultra 4 and Castrol Power 1 Racing. The Motul 5100, Castrol Power 1, Shell Advance VSX and Silkolene Super 4 are good cheaper alternatives.

Cheers

Currently running the Castrol Power 1, was slightly disappointed with it to be honest, didn't notice any changes from the Yamalube I had in there previously.
Thinking of using either Silkolene or Shell fully sinthetic next time just to experiment with what works best with my engine.
I use only BP Ultimate in my bike, so want to treat it to only the best in oils too ;)

Did you get the Power 1 or Power 1 Racing? The normal one is a semi, the racing is synthetic.

If you want the best, go for the Silkolene Pro 4, it's one of the best on the market, the only similar ones are Motul 300V and Redline.

Cheers

Hi Tim,
I used the Power 1 as I told the Power 1 Racing was a waste of money, as they don't differ a lot.
I will look into the Silkolene Pro 4, thanks a lot for the advice.

Hi

I think the person who told you that saw that there is only one word different between the names, so there can't be much difference in the oils, but there definitely is. I would still go for the Pro 4 over the Power 1 Racing as the Pro 4 is ester based.

Cheers

First, check how old it is... I'd only use oil from an unopened container (Might sound a bit silly, but you never know... Don't want water or other shiiiit in the engine)

If it is GTX Magnatec it will be old as that has not been around for some time. It is now GTX in a white tub or Magnatec in a green one.

I wouldn't use it in the bike.

Cheers

Hi

I would use a 10w-40 in the engine.

http://www.opieoils.co.uk/c-782-10w-40.aspx

The best oils there are the Silkolene Pro 4 and Comp 4, Motul 300v, Redline, Amsoil, Shell Advance Ultra 4 and Castrol Power 1 Racing. The Motul 5100, Castrol Power 1, Shell Advance VSX and Silkolene Super 4 are good cheaper alternatives.

Chain lube is a tricky one, the best ones seem to vary from bike to bike and then the owners opinions seem to differ as well. I'd say go for any of the ones from a reputable company, or one of their race products if you want the best from them.

http://www.opieoils.co.uk/c-506-motorcycle-chain-cleaners-oils.aspx

I'd use this as the coolant

http://www.opieoils.co.uk/p-947-motul-motocool-factory-line-ready-to-use-cooling-liquid.aspx

Pro RG2 is a great all round grease and not too expensive.

http://www.opieoils.co.uk/p-824-silkolene-pro-rg2-racing-grease.aspx

This is a really good degreaser.
