Sorry but this will be a long read.

Sorry, but a dyno test will have no precise bearing on engine size..

OK I guess many of you have never heard of Smokey Yunick a well know NASCAR guy... Well he is famous here in the States (his book makes for great reading in the winter)... He was very smart at his rule interpretation. When the rules stated a maximum fuel tank size, he used very large diameter and very long fuel lines... But he did NOT technically cheat..! When he got protested they took his fuel tank to measure, and he drove the race car back to the pits.. duh..! Then the rules on fuel lines were added... Not long ago here comes a race car that just didn't look right.. sure enough it was like 7/8ths scale.. Now they have "templates" to measure the car size.. and on and on....

Ahem, now I think a few years ago, someone got caught with a super big fuel tank...

BUT, when there is a regulated inspection the temptation to cheat is reduced for sure... Plus it takes away the "Bad Guy" aka the one who files a protest...

I am NOT suggesting more rules... I happen to like how clear the rules are overall..! And on motorcycles Vs cars you can see a lot more...

A few years ago at Daytona, the 2nd place racer had an illegal (by rule) component on his bike. It was obvious.. even the announcer mentioned it.!! No, I did not file a protest, as my bike was slower regardless.. However that rule was wrong, that component was used in the day... So what I did AFTER the race was suggest a rule change, and provided the documentation why that component was indeed raced in the day... the rule got changed almost immediately...

Now what I do not understand, is how this is a big expensive deal...?? Sure it takes time (some engines a LOT of time) to do it, but what a gasket or two..?? There is no need to do a total rebuild... just clean everything and put it together...

And yes I have seen a few racers that have like zero spares at the MGP... Wow..! With all the cost of getting there, not even having the basic spares is not a good race plan... I am as broke (or worse) than the next guy, but when I come to the Manx, I have almost a complete spare engine (I want a complete spare.. hope that happens this winter) complete spare ignition, etc... Some guys have a complete spare bike..! (lucky them..!!)..
