  1. Well I got MY motorcycle "ticket" in the early sixties. .

    But have *you* designed an aircraft engine yet? - otherwise you're not allowed to comment in this thread 008_roflmao.gif.692a1fa1bc264885482c2a384583e343.gif

     

    Hmm, seeing some of the responses I should mention that is humour.

     

    Moto Guzzi ... It was their work with chrome bores first that led to their patent (Niguisil). .

    You mean Mahle in Germany made Moto Guzzi motorcycles? Well I learn something new every day. 066_naughty.gif.fdb194956812c007d0f5d54e3c692757.gif

     

    I have seen MANY,many bores with over 200,000 kms on them with very little wear..

    Sadly so have I but now I do work that makes money instead.

     

    The only time wear was evident was when people took off the air filters. .I saw lots and lots of rooted cylinders with nikasil bores but they were all two strokes ( Poor air filtration and ring problems) .

    Oh, so you have seen some worn or damaged then. Not always people intentionally taking the air filters off either, sometimes not seated properly, sometimes well overdue for a service etc. - humans acting like humans. My point and my only point was the result of that is much more serious than a steel/iron liner under the same conditions, you seem to have missed that point, twice.

     

    The bores are replatable quite easily ..

    Shirley your not alluding that replating is as easy and as simply running a hone down a steel/iron liner?

     

    Also you will have to send the cases away because there certainly ain't one around every corner and then you'll have to wait till they have enough to do a batch or you will pay a premium to have yours done individually.

     

    ...........The bores on the D-Motor will be fine....

    Besides you not being able to prove that statement either way, I never said they wouldn't be.

     

    Are we clear or do we meet behind the Mornington footy grandstand on Friday night to sort it out (harking back to my teenage days 006_laugh.gif.0f7b82c13a0ec29502c5fb56c616f069.gif ) - I grew up in Hampden St. (I see you're at Tyabb).

     

    Don't take this too seriously guys, I'm not 002_wave.gif.62d5c7a07e46b2ae47f4cd2e61a0c301.gif

     

     

  2. bexrbetter - lets all get cynical, sarcastic and generally nasty over this interesting and serious engineering endeavour.

    Yeah, nah - just having a technical overview and debate. Apparently you missed where I said the engine's lighter weight and smaller frontal area may "have advantages".

     

    Lets start by you showing us the aircraft-grade engine that *you* have designed, tested and built, eh?

    Hmm the words "cynical, sarcastic and generally nasty" first came to mind reading that ... 006_laugh.gif.0f7b82c13a0ec29502c5fb56c616f069.gif

     

    But anyway jokes aside, sure, in a few weeks the announcements will be made, just organising the company structure, land and factory these very days to produce *my* own unique bespoke to light aircraft 100hp engine. Designed by *me*, patented by *me*, tested by *me*, built by *me* and paid for by *me* - hope that helps, eh?

     

    If you want to knock the Nikasil then you've got another thing coming.

    Got my motorcycle mechanic ticket in the 70's in a Yamaha/Stihl dealership, have motorcycle engines that have powered bikes to Australian and Queensland titles in both road racing and motocross as recent as 5 years ago (all 2T). I've seen piles of 'effed' Nikasil barrels thrown in the rubbish bins out the back of dealers shops before some specialst shops started to find ways to repair them. I used to grab them out of the bins to cut them up to experiment with porting. Because you had a good run from one, as most do, doesn't change the facts of where one small mishap will leave you.

     

    Besides all I refered to was the cost that will have to be born when a bore has a problem and I provided example of a business who all they do is repair Nikasil linings, a bit self explainatary isn't it? Ok, maybe not so I'll explain it - the shop is in business because there's lot of damaged Nikasil linings to be repaired, but that's for single individual barrels, have fun trying to get a matched set of DMotor cases repaired.

     

    That you had a good run from an Italian bike is quite impressive by the way 006_laugh.gif.0f7b82c13a0ec29502c5fb56c616f069.gif

  3.  

     

     

     

     

    Q. But isn't that stimulating the economy of China ?

     

    A. Shut up.

     

    Instead, keep the money in Australia by:

     

    1) Spending it at garage sales, or

     

    2) Going to the footy , or

     

    3) Spending it on prostitutes,or

     

    4) Beer or

     

    5) Tattoos.

    How awesome is it to do business in China and come home a few times a year to spend my earnings!

  4. Aviation incidents are probably the most over dramatised and heavily reported accident that can happen, outside of nuclear accidents, so to the general public, flying is dangerous.

    Indeed.

     

    503, I come from a heavy motorsports background and have lost a number of friends from motocross, road racing, car racing and rallying over the years and then theres many others I never knew.

     

    Then there's horse riding, how many broken necks have resuted from that hobby?

     

    They don't get anywhere near the press that airplane crashes do, sometimes nothing at all.

  5. Hi Mothra and welcome,

     

    Know the pain well, stated off on a Honda SL70 mid 70's and been on them ever since to the point of arriving over here anyway.

     

    Getting older so in more recent times I started the Queensland Vintage MotoX Club and ran it for 8 years or so, oldies on natural terrain MX but still managed to bang a few corners every now and then!

     

     

  6. Thanks Bill,

     

    I talk with one of my Daughters in Oz often with Viber for free - that's talk, not message with my missus iPhone (i refuse to walk around with a brick in my pocket).

     

    Of course Skype (free) is still my favorite and has the world's largest volume of International calls at the moment.

     

     

  7. Jab .. piston speed of only 488.4 metres per minute at the rarely seen 3300 rpm spells low stressed .....Lycoming IO-233 comes in at 551.04 metres ...

    Indeed it is low stressed and glad to see someone recognises piston speed is the factor not rpm, as your example with the Lycoming shows, but it seems to be quite clear that Jab's do not have lower end problems so it's a moot point.

     

    The extra rpm however can effect many other systems but most importantly it is the extra heat that has to be disipitated (to the fourth?) which I think sunfish was alluding too?

     

     

  8. Call him. Win his trust. Take him flying.

    Exactly.

     

    Organise to have coffee with the guy and show him what responsible caring people you are who love a hobby that he may not fully appreciate. Explain that there will be no parts falling or buzzing at 2am and why.

     

    I ran a classic motorcross club for 8 years with noisy old 2 strokes and would always visit neighbors close to where we raced and explain what was happening the coming Sunday as well as didn't start bikes before 10am and out of there by 4pm.

     

    Consideration for others is the only way to go forward with any intrusive hobby and ignorance will bite you on the ass quick smart.

  9. It's quite likely that the plugs should be a different heat range also because of their placement.

    I was going to add "I bet the plugs are even the same heat range" but thought it was over the top 004_oh_yeah.gif.82b3078adb230b2d9519fd79c5873d7f.gif
