Current technology is the reason you now see a 2 stroke turbo application actually in the mix, Aerocharger (dynotechs Shawn Ray) used to have turbo kits out for all 2 stroke sleds that were popular, they worked good to ok, but they didnt set the bar for other to work up to, as far as hp or sled performance.
There were naturally aspirated engines that could easily win over them. Todays technology has become alot more sophisticated and yields alot better results then yesterdays, same way with 2 stroke engine design, a piston port engine has been superceded by the cylinder reed, then the current case reed.
As for banning a yamaha that does well, Its been like this in any kind of racing. Yamaha had the best 700 triple ever made, the other manufactures quit making 700 triples because the srx was hands down better,relaible, consistant,faster, etc. Grass drag rules catered to the current trend of twin 2 stroke class, causing guys on yamahas to ADD 75lbs more wieght to thier already hefty triple sleds, this allowed the twins to win. The twins already also made 140hp stock and were 80-90lbs lighter sled from the start! If you raced a yamaha in the grass in 700 improved were they mixed the twins and triples you mise as well went home because you were handicapped bad. So it wouldnt suprise me if they add extra rules for any other "non favorite brand" doing well in a motorsport event.
Mike Knapp crushed all the asphalt 1000cc sleds with a 800 cc sled and the other racers all cried and moaned because he had 4 cyls and they only had 3. Knapp took adavntage of the 4 cylinder engine and used it to defeat them. now if arctic cat would have had a current 4 cyl liquid cooled engine it would have been allowed and not protested to the extent that yamahas did for sure!

SPEC - Do you know if Jeff Simon is planning to defend Yamaha at Martin MI now that a power adder class is available. I was very disappointed when Yamaha wasnt even near the finals at ESTA.
Where is this grass sled now? I know it was the record holding grass 500 ft sled 2 years ago till they booted it from competition. It looks like it should be on the tar spanking the field. Looks crazy fast sitting still. Sleds at ESTA didnt look like this proline Yamaha. Must be the rules won't allow.
And this was my favorate sled I was routing for all weekend. Holly smokes if he goes any faster we will need another rule change. I beleive this sled is in the nines. Name on the back of the fold down shroud was " WAYNES WORLD ".

Tony - dont tell me you missed this creature. Don't laugh to hard this guy was fast. I wish I had the et's and MPH - please someone post times. Engine didnt look fantastic and if this guy (from Ontario) ever had the cubic dollars to invest in a motor program like the big teams - then they would outlaw him from competition too! Here's another shot.
