ESE's works engine tuner

[peewee]

Sort of agree Frits, but beyond the dribble, there are some good postings by the serious tinkerers. But, yep, KB is outstanding.

rarely do i ever go on fb but i had to get a peek of the 2t development group frits was refering to. sure enough, alot of rubbish and nonsense from quit a few people that clearly have almost no 2t knowledge. yes there was some skilled members but it was painful to weed out all the bullshit and find the good info. i couldnt agree more with frits, fb is definatly not the type of place for sharing ideas, for the reasons he mentioned

Yes indeed, a very bad group...

Yes indeed, a very bad group...

one guy said theres better flow over a flat top piston. if this were true, wouldnt cars still have flat roofs as well

Thank you Jan for your kind words on here.
Getting to work for TM would not have happened without your support.
Have a very good year my friend.

I simply KNEW you would succeed at TM Wobbly!!
I would have betted on it....

Hello twostrokers happy new year 2019 to all members of the kiwibikers group and thanks to the two stroke pros for sharing their immense knowledge

Remember how finned the air cooled Suzuki twins and triples crankcases were. bloody heavy and hard to cast but they did it. i dont think it was just fashion.

Finning the crankcases may be a great idea, but maybe not in combination with those exhaust headers running right in front of it... Here is another example that makes you think how it could have been done better.

Do you mean my pipes could have been done better Frits - sorry I will try harder in the New Year.

Yeah, it's about time you'd start producing something useful - like better pipes for TM kart engines .
Seriously though, a heat shield between those beautiful wobblypipes and those crankcase pre-heating cooling fins wouldn't be a bad thing.

I really did have an unconditional love for the Ariel! - nice frame and forks, good handler - despite its crappy 'old school' gearbox with its sintered iron bearing, chain primary drive, crowded roller big end bearings, bronze small ends, shrouded cast iron cylinders with tiny transfers, crappy brakes and 16" wheels (more sensible 18" on this case of course). ........ its still beautiful and unique, and the 'wobblypipes' make it even more beautiful - but yes I do agree that crankcase really was designed to attract cold air !

Happy new year!

Happy New year to all!

So fins connecting exhaust and transfer ducts is no good. To 'disconnect' these two we have to cut fins on two pieces. Which duct is getting bigger part of the fin?
If we talk water-cooled engines Wobbly found redirecting flow on transfers first as a gain, and overcooling of exh. duct/spigot as a loss ..as I remember.
Could it be answered without Dyno?
I would go for transfers 70/30% of the divided fin area.

Bear in mind Frits, that the Brits didn't anticipate global warming - or probably export sales to a warmer climate either....
Or anyone getting more than about 19hp out of one....

Have a good year everyone.

I think all things considering as especially as the old 4t Boys network at Ariel were not that happy about the 2t. Val Page did alright with that engine.
He did borrow a bit from the German Adler but so did everyone else.
He did at least have the foresight to mount the clutch on the gearbox which took another 10 years before Yamaha figured that one out with their version of the German Adler.

I have not posted for quit some time. But viewing this forum is part of my daily routine. For all those on this forum that have openly shared their thoughts with the rest of us..... May the new year bring you happiness and prosperity. Thank-You Kermit Buller
