ESE's works engine tuner

[steamroller]

So smartarse show us the dyno chart showing an aircooled 125 making anything like that power at 10500.
And no I wasnt in the sidecar I was in the pit tuning the thing.

How are your 117 hp 400cc 2t going thats right they only made 98 and would not last a day on the track great job .

[wobbly]

Still no 30 Hp @ 10500 dyno chart for a 125, and not one statement of of facts about the 400 correct.
Sadly I wont be back to pass on any of my big headed knowledge as its obviously all wrong.
See ya.

Hey guys, this is not the thread.

[kel]

show us the dyno chart showing an aircooled 125 making anything like that power at 10500.

Can we clarify what "anything like" actually means. On second thoughts please don't, we are already at 28hp at 10.5 and don't want to stop development. Im not sure I could sleep at night knowing you might turn up at the door wanting to honour your offer.

So steamy - you're up here this month for the 2hr, bring the aircooler with you, we all want to see what it can deliver on the dyno

[FastFred]

Check with TZ, so long as the results are posted on KB he always seems happy to run the dyno (DynoJet) for a 2T Bucket.

Cheers guys, I think the boys would like that. Two hours on a bucket, hell, I could barely last one at the BOB! You must be Supermen!!

We will bring it would be good to see what it's at ridding it i think it will be round25 at this stage just don't want it to blow to bits

thought some people might be interested in these cylinders im working on. frits i know you liked them yamahas . im not sure what the hell the person who designed this casting was thinking as you can see the exh bottom is low and wide so ill correct that while im at it. the C seems to be tilted farther forward than what ive seen before. its angled forward 45* from the rear cylinder wall. is this normal practice nowdays ? i miscalculated on this first cap so ill have to make a new one then trace it on some paper and trace that on some tube and cut 3 more.

wouldnt let me put more than six photos

What on earth you doing to those poor athena cylinders The exhaust port needs lowering on those badly to say they are 'peaky' is an under statement but they don't need help making hp 421cc is over 90hp with those

Interesting. If I remember correctly, Phil Irving said somewhere many many years ago that 76* was the perfect angle for a V-twin.

76 in the Honda case was just a co-incidence to do with the 52 degree v angle.
Irvings formula /Theory something I think to do with Max velocity of the other piston rather than just mid stroke. I posted an article way way back. A few Triumphs and so forth have been done at 76 degrees. The jury's out on whether its better or the same than a 90/270 set up, but its still far better than a 360 set up anyway.
I will see how good the Kiwibiker search function is and see if I can find it. (I did)Plil Irving 76 Degree crankshaft.doc

theyre not athenas but i believe theyre loosely based on that casting. the timings are low. around 182/122 i think but i havent checked yet. these are also sitting at 65mm bore right now but ill probly have to go to 65.5 so theyll straighten up. athena bores start at 68mm i believe. i believe theres a few other differences also. now if i could get them around 100hp with methanol i would feel all the effort was worth it. totall cc will be around 391-397 depending how the bore cleans up
