Hi does anyone know if Silkolene Pro KR2 Castor & Ester Synthetic 2T is suitable to use through an autolube
Looking to get the old Castrol R smell from the castor oil
cheers

There aren't any 2T oil road specs. on that.

That isn't a road bike oil and why use that when so many good oils to the correct spec are available? It won't smell like Castrol R neither as it is a synthetic derivative.

Just found out it’s not suitable for autolube
Learn something everyday!

If we look at the JASO specs. for example, the 2t oil specs. FB, FC and FD state that (amongst other things) the oil is suitable for pump use, premix being a given.
The specs. also state that these oils are back compatible to specs. that are no longer in use. Basically, you can use this modern oil in an older design engine.

I got banned on a Triumph site for getting into an argument over what oil is best for a T120. I said of course that the best oil for the bike is the best oil that you can get now which is fully synthetic. He completely lost his rag because the manual for his bike said to use SAE30 monograde as it was "designed" for that. I said that if he preferred non synthetic he should use a 20/50 multigrade which was several leagues better but that 30 monograde was fine for hinges and not much else. |

This is the article I found that says not suitable for autolube.
The best fully synthetic ester based 2 stroke racing engine oil. For use in pre-mix use only in ratios up to 50:1. Proven on track with outstanding load carrying and control of combustion chamber deposits.
Highly resistant to ring-sticking and plug fouling problems, and maintains a high film strength, even at high temperatures seen in racing engines.
Incorporates special additives to prevent throttle sticking in wet conditions, a common problem in carburetted classic racing motorcycles.
NOTE Silkolene Pro2 is intended for race applications with pre-mixed fuel/oil only. It is not suitable for auto-lube systems as the viscosity is too high. For injector/autolube see Silkolene Comp 2 Plus.
I will stick to standard oil. Spent too much on the engine to risk anything
Thanks as always for the advice

Strange how it says the viscosity is too high for autolube. It states that the oil is SAE 30. That's what most 2t oils are. At least they were back in the day.

As a racing oil it will be designed for taking load only in a properly warmed up engine. A Monograde is fine for this but autolube has to manage a wide range of conditions and needs additives that racing oils don't need because they are only used in the moment. Modern oils are superb and possibly the best advance in technology ever. In the 60's engines only lasted say 30-40k miles before major maintenance but that is almost a safe change frequency in a modern engine. OK if somebody said that the best development was FI for 4T's I may agree on a tie. 2T's were totally finished when FI was perfected in 4T's to the point where the only plus that a 2T has is now apart from simpler engines is the narrow but steep power band but awful for a decent road bike. FI just never worked on 2T's as Bimota found out. We can only hope that one day it is perfected. |

My 2009 KTM 250 EXC pulls like a trials bike from tickover and then progresses to 45 bhp thanks to its power valve and mapped ignition. It does however, vibrate a fair bit. I got it new in 2010 to replace a DT125LC , and initially kept treating the engine like the DT, it kept trying to kill me in Enduro`s until I twigged how hard the thing pulled from low revs up steep climbs. Junior got a new 2019 KTM250 EXC TPI as part of the bribery deal to get the slacker to bother passing his GCSE`s and getting an apprenticeship, the lucky git. I put an hour or so on it running it in on the road before letting the lunatic mx racing Junior loose on it. I immediately thought that the engine would be fantastic in a road bike. Perfect "Carburation" and no vibes as it has a balance shaft. Electric start too. KTM have now moved on from TPI , Transfer Port Injection, to TBI, Throttle Body Injection. Quite a few manufacturers do injected off road 2ts now. I think the emissions are still a problem though, Juniors TPI is rated at a lowly 8KW or so on the V5, the dealers remove the cat from the exhaust, throttle stops, inlet strangler and re-map them before you take ownership. I think as part of the official testing bikes to accelerate at full throttle through one of the lower gears ? . 2nd or 3rd would not end well on his KTM in its "Full Fat" version ! |

Doug, I maybe should have said that direct FI has never been developed for 2Ts to the extent that it has for 4Ts, never achieved the incredible results that it has in 4T's? Sorry, the YPVS is the most modern 2T that I've ridden.
