    Which part of 14 landspeed records,an 1/8 mile speed record in a nitro class,crew chief of a dominant (4 consecutive championships including an undefeated season) Pro Stock Harley team,40 years of MX/hare scrambles/road/drag and landspeed racing did you miss .

    I am impressed.

    So twin troll list some of your accomplishments other than the trolling internet speed record you hold??????:ear

    Bringing the KKK and George Zimmerman into this discussion is retarded,

    I live near the Glamis Sand dunes and I know that there are issues about sand that make it unique and special. In deep sand you often need instant power to keep the front wheel light and not digging in. Sand can really absorb a lot of the power from your rear wheel. very often the bike that runs strongest on level ground is not the one that can climb a soft dune with close to a 100% grade the best,
    Every year I see lots of people with lots of theoretical knowledge and knowledge from other areas who put a lot of money into some sort of ultimate sand machine that doesn't work.

    Back to bikes, the geometry and power characteristics that make the best sand bike are somewhat different that what makes the best motocross, dirt track or trail bike.

    Guys I think it's time we stop responding to Twin-shitter:topes:topes. Let him pass his gas and ignore him. No one in their right mind will take him seriously anyway. You can't have a battle of wits with an unarmed person.:lol3 He's obviously got mental issues and a hard-on for Americans. Continue the threads , but let the TROLL die alone.

    Its very very easy to post up BS on chat forums isnt it! The fact that the person posting the stuff outlined above, doesn't seem to have a clue about very basic areas such as 2T lubrication, very much qualifies the fact it is BS dont you think?

    Joe up to now you have posted nothing whatever of value on this thread, and have merely taken issue about technical matters, which you clearly simply do not understand.

    If you do have any grasp of technical matters, then please post up something to support the idea of autolube oil being more suitable for use in pre-mix bikes, than a proper pre-mix product?

    Thats something that seems to be taken as read among the rather large troll community on here, even though not one of them has been able to provide any objective reasons for their curious claims.

    A poster on here made a rather unpleasant racist comment, and I simply pointed out to him that had he done this in the UK, it would have been against the law!

    Like many posters on here, you seem unable to grasp the fundamental idea of the need to reduce jet sizes, to compensate for lower air density at higher altitudes.

    This seems curious as its very very basic stuff, and is well documented and explained all over the net?

    Once again you have proved you are a mental midget.

    Joe is right we should just ignore your ignorant self.

    I'll give the person who can point out where I said autolube is better than pre-mix oil $20. The only place I've mentioned it is in what "I choose to use in my race bike[/i]".

    I use Amsoil Interceptor in the RZ because of it's base stock characteristic of not building up on internal parts,i.e. powervalves. I like the fact my 140+ MPH RZ 350 does it with the oil pump,pump gas and tags.

    In the YZ I use H1R which is a pre mix only oil mixed at 32:1 as recommended by BelRay engineer[/]. I used to run a leaner oil/fuel ratio until a conversation with a Bel Ray engineer at a trade show enlightened me to his view more is better when it comes to fat guys (me) on old air cooled race bikes in the mud on hilly race tracks, a la Budds/High point.

    And don't be impressed slideways. If you devote all your time to something for 40 years you'd better accomplish something. It's nothing many other people haven't done as well. all that hard work oughta amount to something.

    We must have spoken with the same engineer although I am sure twin douche will be along shortly to tell us we are wrong.

    I raced a YZ490 back in the 80's and ran it at 32:1 with Belray mainly because I was more worried about bottom end lubrication than I was ring and piston lube. Piston speed was not that high on that motor. The great thing about the YZ 490 I could pretty much stick it in 3rd gear and rail. My 140 lbs gave me a huge power to weight ratio against most the people I was racing against.

    With my shifter cart which had a TZ250 motor in it. I ran it at 20:1 with YamalubeR and race fuel again I was more worried about the bottom end than rings and pistons ,which were changed frequently.

    On my modern 2 strokes that do not get rebuilt as often and have power valves I find the Castrol TTS works very well. Thin enough to properly lubricate the top end and not gum up the power valve and thick enough to keep the bottom end lubed. I still jet for and mix at 32:1. I also stay away from ethanol fuels.

    I'm still impressed:D

    The Honda's have great power, but depending on the year, they have bad headshake at speed. The KX is a really stable bike and would be my pick.

    Hope this gets back to the OP's intent, instead of the ongoing crap in this thread. And yes I have rode both at high and low rates of speed in the California desert for than more just a few minutes.

    Is there an official big bore 2T picture and discussion thread here on ADV? If not do you think we/I/someone start one? :evil

    This one was off to a good start before the train wreck.... :huh :*sip*

    I think that's a great idea, Andrew! Make it any year, 400cc and up. :thumb

    You have a nice bike to open it with. :evil

    Great!

    That will be just the thread for Twin Troll to post up pics of all the big bore two strokes he has owned.

    I'm sure he has had so many that he will fill up the thread by himself...:lol3

    You dont seem shy in posting up how very ignorant you are! Castrol TTS is primarily an autolube type oil, best suited to autolube machines, and or pre-mix play bikes, where the use of excessive amounts of oil dont really matter that much!

    The main reason to avoid using autolube oils in serious pre-mix competition machines, is that the mix ratio required in almost double what would be used with a pre-mix only product, as autolube oils are commonly diluted by up to 30% solvent content.

    In terms of lubrication and corrosion protection, a proper pre-mix only full synthetic 2T oil such as Castrol XR77, will work a great deal better than the very thin autolube products.

    However as most on here seem to be play-bike riders rather than serious competitors, its easy to see why there seems to be so much confusion over selecting the best possible 2T oil to best suit a particular application.

    Something that seems to be overlooked by the very vocal community of trolls on here, is that autolube systems have the major advantage of being able to vary the amount of oil supplied in direct relationship to throttle position. In effect this means an autolube bike at tickover engine speeds, may be running at a mix ratio of 150:1 or more, and at full throttle maybe 15:1.

    Obviously bearing in mind the above, an oil designed for autolube use, is far from ideal for serious pre-mix bikes, and must be used at around about double the mix ratio which would be suitable for something like XR77.

    Like it or not using autolube oil in pre-mix bikes is never going to work as well as using a purpose designed product, and can be compared to using MX tyres on a trials bike, or vice versa.

    While you are correct about the auto lube system metering oil at different rates for different throttle positions, you forget that the carb also meters the amount of fuel at different throttle positions.

    So the auto lube pump increase the amount of oil to maintain the oil mix because of the increase in fuel drawn in by the carb.

    You're welcome.

    The level of ignorance concerning very basic facts related to the operational principles of 2T motors, is something that I find rather surprising!

    Those posting on this thread seem to have little grasp of the reasons for needing to use almost double the amount of autolube oil, over a specific pre-mix only product, and are seemingly completely oblivious of the negative effects that excessive amounts of oil have on the combustion process.

    Choosing to use a purpose designed pre-mix only oil in a pre-mix bike, over an autolube type is a win win decision, as this will mean improved lubrication, and better performance (if the autolube oil is mixed at 30:1 and the P/mix only at 60:1).

    However for reasons as yet known only to the troll community on here, it would seem the whats outlined in my last paragraph does not apply to 2T machines owned by them. Not sure why that is, but fine by me if the trolls choose to compromise performance and engine life by using oils that are not best suited to 2T pre-mix machines.

    It was amusing to watch you make a fool of yourself for a while, but now you just keep repeating the same crap.

    While I still do enjoy watching an idiot who has a small amount of incorrect knowledge gained by reading crap on the internet posted by equally clueless morons, being torn apart by people with actual experience and knowledge, you have grown tiresome and embarrassing to watch.

    So please feel free to quit posting your dribble in ADV, and instead read and learn.

    And as a friendly reminder, you are being watched by mods (as we all are), and I can see a well deserved banning in your very near future.

    Thank you, and have a nice day.
