Mini Twin Police!!

Pair system removal(mine is removed is this illegal mike?)

That aint legal - several riders caught out last season at MRO minitwins with missing solenoid and pipes - all blanked off. It has to be present as per stock bike but doesnt have to work.

Straight from Mike Edwards (horses mouth)

Gav you cheat!:-p

Landed myself in it ther haha

Some very very good riders between the two clubs, and yes a good fresh debate.

The intersting point about this is the minitwins rules have always been based on SAE method and dynapro dyno's.

Dynojet dyno's read higher as you've demonstrated above, and are usually quoted in DIN rather than SAE. Pretty much any machine that reads 75 bhp or less on a dynojet machine will actually be class legal. Above that I'd start to worry about yer legallity!

The minitwins site is down, but the regs in full are on the BEMSEE site;

The rule clarifiaction is also worth reading, a ram air effect isn't against the rules (if done right)

as said the bhp limit is 72hp. for minitwins. is this why you dont see people racing hyosung gt650's as the quoted hp is 82?

so if a bike comes from the factory producing more hp that is allowed would you have to de-tune the said bike?

Rab Davie used a Hyosung in Minitwins at Knockhill and EF in 2008/2009. IIRC he won the KDMC Championship riding it.

More intresting points here;

Hyosung, dont think they are really 80 in stock trim (although Hyosung claim it, it has to be a crank measurement)

800ss is an easy one to explain; they dont need detuned, a set of cans, K&N filter and a power comander lift you up to the class limit from about 66-67 ish, and thats it, nowt else is touched. The Ducati advantage is more torque, but this is levelled out by the extra weight...... also it's all over by 8000 rpm, SV's and ER's rev higher and liquid cooling always gives a higher specifc power for a given capacitry compared to air cooled.

Did anyone ever read my build thread on Ducati up north? I did a couple of posts on dyno stuff between the SS and the ER6 (strongest engine in the class from what I've seen)

I think a 796 would struggle to get below the class limit; it's a modern engine streets ahead of the ss lump in design but; I reckon a 696 could easily be set up to be 70-ish hp and would be the better bike for doing so, lighter and more nible than the 796, double sided swinger helps a lot with this.


Apart from all that, I'm all for a dyno............... at a meeting near me soon!

Remember to generalise and not be specific

We all agree atleast a dyno test would stop the cheaters (i could be specific but i wont) as well as the wingers !

There were only 10 mintwins at Croft this weekend? Is that not telling the club summit? Gordon you choice to race where you want is exactly the same thought both Tony and I am thinking, so how many others have or will their be?

Clubs tend not to think in terms of the class but the grid. That much was evident at the club meetings I went to. And the ultralight grid was big so they see the class as a success and I can understand where they're coming from.

If we want things better for our class we're going to have to fight for it. 22 minitwins on the Sunday at east fortune I think, if you added the north east lads who don't race with Melville it would be over 30 minitwins. Only bemsee can better that in the whole country.

The interest is there, we need to take a leaf from bemsee's book now and start doing it right.

so what if your bike isnt making 72 hp. but you wack a tank riser in or remove the snorkel to give you that extra bit. so it makes it 72 hp. would that make any difference. as long as your bike is under that magic number
