Interesting explanation of the various engine configurations in an explanation of the T plane Triumph engine. Why does everyone think that the Jota was the only Laverda triple? Sorry if it has been put up before.

Interesting, but not exactly new, Lee. I was actually wondering when one of the major players would come up with it! At OCT we calculated the balancing for a 90/270° Laverda triple about 12 years ago.

A friend is an engineering genius and wrote a series of computer programs to determine internal forces and to aid static balancing. Calculated component forces and the probable resulting performance were quite promising, but it would have been quite difficult to tame the vibes without a balance shaft! He also did the calculations for my lightened triple crank, which turned out very nice indeed!

About time for a 180° triple renaissance... before Lithium takes over completely. ;)

Yes, he put together a clear and concise explanation. But he's still fallible. He got the gap between power pulses wrong for a single cylinder engine.

It was a little disappointing that he failed to mention the advantage of a flat plane triple crank in that it doesn't have a rocking couple. But I guess it's not so applicable because nobody is building flat plane triples today.
 

You can buy his book " Life On two Wheels " .....Note he did this on his own with no backup vehicles , or spare BMW to jump onto when the first one breaks down ( Charley Boorman ) ....

This was back in 2001...I expect most of those muddy roads are now six lane superhighways built by the Chinese.....

And the part that follows on .....

( BTW...there`s no need to remove the clutch to disengage the chain that drives the oil / coolant pump in order to remove that pump....there`s room for a 12mm ring spanner to undo the bolt retaining the pump drive sprocket from underneath.....sprocket with chain attached can then be moved clear enabling the pump to be removed from below without bothering the clutch at all....only thing is , there`s no room for a torque wrench when re-assembling drive sprocket to pump....however if you`re sensible and don`t go mad with the tightening plus using a dab of threadlock you should be ok......) .......

Have`nt seen all of the Itchy Boots but remember one where she had ridden into a village in Peru , I think , just as the Covid thing was getting underway , and she was stuck in her hotel room frightened to go out as word had spread around the village about this female stranger who had just arrived , and the possibility she had brought the virus with her....I`ll have to search that episode out , and see it again , but I think she got safe passage out with the help of the local Mayor......
 
She had to abandon her bike and had to pay a local to do a non-stop car trip for I forget 100ks of ks to get an evacuation flight out. They passed through dozens of Army and Police checkpoints with big risks to be stopped and detained, her documents were close to ok and some Police Head honcho gave her his Cell number if they had issues. She got out waited out the Pandemic in Holland then went back to South America and, well I won't spoil it. I bet the way she is going there will be a Dakar in her at some point.
 

I expect most of you are familiar with these...but couldn`t resist it anyway...gives me the goosebumps everytime...especially the star / pentangle thing towards the end.....

Reminded me of riding the Crane box up 68 floors of The MLC Centre in Sydney and being told by The Dogman to crouch down in the open end as it wasn't strictly OK. Halfway up I started thinking if the sling slips and tipped the box towards the opening I would fall out. I didn't but it freaked me out a lot before that heights don't worry me. They do quite a bit now. I guess it's a tiny bit of PTSD.

I developed a fear of heights from one week on a Tower crew. Two towers: My First tower, the experienced guy was standing on top of a 300 footer and jumped out the the microwave dish, missed it and caught a tensioning bolt tore a nail off his hand. Second tower, a lightweight frame, in high winds the tower was twisting and bending in the wind and I freaked myself out thinking about the one safety harness, instead of two I was suppose to have. Ever since then I have had a a fear of heights. I learned you don't have to be crazy but sometimes that helps.
