I am busy getting ready to go to the Czech Republic for a special holiday to take part in the Dvur Kralove street races with Paval Simak on June 30 / July 1st. The Next weekend we are at the Grossglockner Trophy event in Austria. I do know that Reinhold Sprenger will be there with his Scott also. As the Grossglockner highway is a toll road, they can close it for a short while for the event, but practicing must be on a street legal bike on open roads. We had to do the same at the Klausen event with Charles Windsor and other Scott riders a few years back.
I am making equipment for holding the 1990 Yamaha RD350 YPVS on the trailer to use for practicing as it is the nearest thing I have to the Scott, which is, when you think of it, a great compliment to Alfred’s design. I just will need to remember the gearchange is the opposite side and backwards! There seems to be more events for the older bikes over the channel than here as the number of old bikes on the grids are down to a small handful. Roger
I am holding (for about 2 years) some Windle sidecar race forks for Pavel, do you have any spare room?
They would go on the trailer. Can you get them sent up to arrive next weds latest?
😀 😀 😀 Good Luck Roger!!!!!!! DONT Crash 🙄 🙄 😀 😀 !!!!!! Ted
I hope you have great holidays! I participated in the 2010 edition of Grossglockner trophy and indeed practising is done with normal traffic. I am sure that you will enjoy not only the race but also the views and the environment where this race takes place as well as the kind atmosphere and efficient work of the organisation team leaded by Thomas. I am actually regretting not being able to attend this year again. Good luck!!

PS. Be ready for the cold… it snowed in 2010! 🙂
Hi Juan. Your description reminds me of the occasion when Ted Parkin and I went to the Klausen event. It snowed there too! I am much looking forward to it. Kindest Regards Roger
Congratulations to Roger for his continued racing participation at the grand age of 71. I know he will enjoy the Alps again as much as in 2002.
There used to be an adage that “racing improves the breed” – AAS proved it 100 years ago and it’s still true. Roger, through his long racing career, has made many contributions to enhanced performance and reliability of the Scott engine from which we can all benefit. Linking this with the adjacent thread about Banbury Scotts and the subject of piston seizures (and the valuable advice about running the engine on the rich side ) there is the fact that through-piston porting to enhance transfer efficiency also helps to cool the pistons and reduce distortion.
Lofty Avis had his share of piston problems in the early days including severe skirt ovality. His successful use of wooden vee blocks in a large vice to re-distort oval pistons was documented. I know Roger will shudder but we must remember that most enthusiasts operated on a shoe-string back then. He also used a single crankcase packing block under the piston to displace trapped hot gases and help in the cooling process – having noted that Schnurle-type transfer ports encouraged the flow of cool mixture through the pistons in modern two-strokes but “which could not be applied to a Scott”.
I don’t know for sure who came up with the Scott version of through-piston porting – perhaps George Silk ? – but it was certainly not known about in the Lofty era, pre 1967. I can’t recall him writing about it in his later articles but he would certainly have recognised its value.
Thank you for your kind words Mike. AAS was a man who’s memory I hold in the very highest respect and was one of those rare human beings who were born with a degree of natural talent that is seen but rarely each century. It is a privilege to play a part to keep his creation in use and, as far as possible, in public view. I certainly do not claim to have originated ported pistons as George Silk was doing this before me. If an idea has logical merit, I will try it in racing conditions and develop it to my entire satisfaction before making it for a customer. Contrary to the belief held by some, I do not “Tune” engines in the way that reduces their suitability for road use. My efforts have been expended to make the engine smoother, more tractable and to have more torque. My greatest satisfaction is to receive a few words of appreciation from a customer. I am much looking forward to racing in the Czech Republic and Austria with other Scott riders and to demonstrate to others a little of what they are missing!
Thanks for your kind words re Roger Mike! 😀 😀 Your post re-kindled memories of the horrendous conditions we all experienced at the Klausen in 2002 where us Scotties (with my late fiancee’ Pam Gander) raced in similar weather. I still shudder at the memories re those conditions but have to laugh when I watch the video of you performing a tooth repair in your caravan as the rain hammered outside!!!!!! 8) 8) 8) “Wot Larks eh!!” (Charles Dickens) And as Roger remarked to his amazing wife Marina as they lay in his motorhome listening to the rain sheeting down on the roof in the early hours “Arrh! Listen Marina! The sound of Switzerland” 😆 😆 ! BTW its always been a complete mystery to me why Roger Moss has not been afforded Honorary Membership of the Scott Owners Club in recognition of his unique contribution to the Marque.????? 🙄 🙄 🙄 However, and personally, Im a great fan of Groucho Marx’s famous remark who said ” I would never join a club that would have me as a member” Regards to All Ted 😀 😀
