Desmoduo newbie - maybe
 
Been wondering about this for a while. Maybe i'm missing the 1098 & need to own another Duke but i seem to be thinking about this on a regular basis lately.

I know it's down to corner speed & keeping the speed up but how likely am I to get above 10mph on a 620 when I weigh 17 stone without the leiderhosen?

Had a little look at the regs & can see it's aimed at keeping costs down, so does that mean most people are running totally stock motors that have just been refreshed?

Any major rule changes likely for next year?
Maybe a rule with a minimum overall weight for rider & bike & everyone under has to carry a haversack of lead shot around?

The intention is to keep the rules pretty much as they are

Depending on your build you may be more suited to one bike than another

If you have short body and arms then the Monster is probably a better bet than the Supersport due to the shape at the back of the petrol tank.

Rules don't allow the engines to be tuned so its all about getting the setup right, cam timing and fueling are the main things to concentrate on

That’s an interesting way of deciding that I’d not thought of. Short body, long arms (sounding more monkey than human) & 6’-1”. I’ve ridden 90’s 900SS, 916 & 1098 & all felt comfortable never even sat on a monster.
When I’d been looking I’d decided on the monster because looking on Ducati site they seemed to be lighter than 600SS as a road bike & a bit more power on the latest one.

Can you get the SS down to the same weight easily? I was surprised at the weight difference quoted & not fully looked into why & where it is located.

Can you change the valve seat angles at all or just ensure they are well bedded in? Offset woodruff keys for valve timing or do people go for vernier pulleys. I noticed you can change the clutch for a slipper, I can’t remember whether the 600 engine is a wet clutch, do you have to retain that or can you go dry?

The difference in weight between the ss and the monster is probably just the fairing .. once they are stripped down into race trim they're much of a muchness

timing can be advanced/retarded but that's your lot

get hold of a cheap bike and join the fun .. You'll not regret it

pbrown 08-Sep-2013 18:32

Weight of fairing makes sense.

Not many changes so I suppose it will be a cheap race series to do & fun.

I'm just waiting to see if i'll be riding in the HT paddock next year before jumping into the Desmoduo series as well.

I'm not far off 17 stone myself and just won my first race at Brands today, still on a high. :D

pbrown 08-Sep-2013 22:00

That's good going & good to know you can still do well even when carrying a bit more weight than some of the featherweights.

i'm nearly 16 stone now, I can usually run near the front,, but weight is huge disadvantage, i'm usually the slowest down the straights.

bradders not a light fella and he was propper fast too.

pbrown 11-Sep-2013 14:12

Not expecting to be a front runner, as long as i'm competitve enough to have a few dices with people thru' the race & not get left for dead on the start line I'll be happyish.

pretty much everyone has someone at about their level and usually someone just ahead to try to catch.. (unless your Dave Woods or Tom Halifax)

pbrown 12-Sep-2013 13:17

Sounds good to me. Just waiting to see where HT decide to go next year although I suppose i don't need to do full season.

Never mind the two racing snakes who have won their respective championships, all they have is; speed, energy, skill, youth, a lack of fear and the ability to buy slim Italian off the peg leathers that fit perfectly.
Whereas we have science on our side;
speed = distance x time; well I know with the amount of times I overrun corners, get on the wrong line and generally wader round the tracks I am covering more distance than they are, and at my age time seems to fly past, so it stands to reason the speed is good.
Then of course there is E=MC2; so if Energy is Mass x Speed (of light) squared....well many of us have pleanty of that mass stuff, so the combined mass and speed of everyone else is.....well, bloody staggering!
So I think the reason that these two have just buggered off into the the distance is that they have to, because if they slowed down at all, they would get flattened by speeding mass following them!
So come and join the speeding mass and have fun with us on the back seats!

love it, I wonder what the combined i.q. of a full DD grid is?

Somewhere between 20 and 36 depending how many are out there

I've got one of those i.q. thingys, my Mum and Dad gave it as a birth day present, but to be honest have not really used it, especially when racing when I just leave it at home!

So to deal with a vampire it's a steak in the heart, and now I find out that to deal with a ghost it's a pork chop up the nose!
Funny what you learn in DD

My only problem is that first, you have to catch your ghost!

Put a tin of Magners under a box that's propped up with a stick, tie string to the stick, keep hold of the other end of the string and hide.

on the DD forum, it doesn't matter what the thread starts off about...........

spotted where you going wrong

Lol well done Miles. The formula is usually quoted as S=VT where S is distance V is Velocity T for Time. :D

milesaway 15-Sep-2013 18:33

badger trap
 
question is would you fall into the badgers magners trap or wait till he's shot and drink the cider?

chris.p 15-Sep-2013 19:17

But when you facter in time and relativity, along with gravity, ability and weather, well any thing can happen :D

Doh! I suppose that means detention.....again!

So if the formula used to find the distance (s) which an object travels with a given initial velocity (u) and acceleration (a) for a given time interval (t) is;
s=ut+1/2at^2

This can be rearranged to get t where
s=ut+0.5(a)t^2
s=t(u+0.5at)
t=s/(u+0.5at)
t^2=s/(U+0.5a)
t= sqrt of (s/(U+0.5a))
Giving: t=[(2/a)(s-ut)]^0.5

This means that t is about quarter past four, u (speed) is....."Oh crap I'm in too hot again", distance is well bloody miles away from Oban, and all this gives rise to the inescapable conclusion that Mister DW jnr. and Mister TH will probably end up at the front...............again!
Ah well so much for science!
