what is the best oil to use in it?
cheers paul

i just used what the bike shop recommended, wasnt expensive. I can guarantee they know more about bikes than me!

synthetic oil or not ?

I use semi synthetic Motul in the bird, never had clutch or engine problems, get a free oil filter with 4 litres down at local bike shop so maybe that helps my choice a bit.

oil not a prob can get any grade (from work)
just heard about synthetic oil (slipping clutch)

Castrol R4 superbike

I am probably teaching you too suck eggs but if your getting your oil from work make sure whatever you do its for bike engines, car oil as too many slippy additives in that does cause clutch slip.

Apologies if Ive got you sucking eggs but I would rather do that than have you put car engine oil in......

Yep, as Jon said car oils will cause it to slip, but Ive never seen anyone have clutch problems with synthetic bike oil despite what some people seem to suggest.

Ive always either used Castrol R4 too, or Redline.

Just out of curiosity, how often would you change a fully synthetic oil?

The bike shops round here use Valvoline 10/40 exactly like I use in my pinto. No one ever suffers clutch slip from it.

Castrol R4 5W40. Fully synthetic but designed for wet clutches.

Blimey, must be a first for me, loadsa peeps agree with me..

Been using Castrol R4 in superbikes for years and never had any issues, plus it has a nice smell...



Its only car synthetics that cause wet clutch problems as the oil has additives such as teflon that cause clutch slip...

well didnīt run with the car but managed to waste a couple of time my oil!!

Started with 4litres of motul!

then i wasted another 4 of ipone...

i have now in another one but cant remember the brand should search for the
bottle... anyway i dont like mixing oil brands sow the last time i also changed the filter.. nad then the 4 litres are just enough! every other drop less and i cant get at max level...

Dunno its my first build, sow managed a couple of times to top it up, and then i needed to take it out, and because of the oil cooler i always had losses...

then i topped it up with ipone and i had a slow drive on a bad road (where no cops come) and i broke the sump!

sow another 4 litres in the middle of nowhere spoiled...

i saw the leak because the engine died (drove to slow)

then the river grow and i could see that i should shutdown if i wanted to drive again in my life!

was lucky that it only had a hair cut in the alloy sump sow the oil wasnīt gone with the second...

Donīt like changing sow often!!
not for the engine! not for my pocket..

but there is only one way to learn!

what i learnd, do it one time on your highest level possible...

and never change a winning team (something that works)

Hellfire, I usually do it maybe every 3-4 trackdays with a bit of road use in between as well, or earlier if it looked/felt like it was past its best.

Wy chris??

Isnīt a matter of miles? running meters??

how much hours is it??

regards,

Tks

Do you mean why so often? I guess in on average its probably a little less than 1,000 miles between oil changes, but when half of that is track use with the engine getting far more abuse than it could possibly get on the road, I don't think its unreasonable. In the scheme of things its not a huge cost either, ie an additional Ģ10/trackday if you change it every 4 events.

cheers
