I cant open either... i'd like to see a dyno graph, I'll bet the cams make more hp up top but you might lose that perfect torque curve which make this bike so great out of the turns

It works if you go trough the website.
Go motorteile, fill in KTM, then cc then 990 sd.
It shows the cams and pistons

Ahhhh Joe,

You strike a note with me there my friend.

When I was younger I was totally into motorbikes, it made my life whole and I found something that was, and still continues to be, a passion that has not been matched by anything since. But I had no cash and the experience was one of riding and the freedom and buzz that riding on two wheels brought me. I had old machinery that was barely adequate for the job but it's all I had. I had mismatched tyres, inadequate suspension, worn barrels and leaking engine casings. But I was out every evening, down the pub, with my biking fraternity. Riding every night and every weekend. Because I had no other commitments.

But I have grown older, and life changes doesn't it?

I have very little time now to ride like I used to. I own a company, I work long hours, I have a family, (my lovely Amy and children), I have SO MUCH OTHER STUFF TO DO! :lol: But although I have less time I have more money now and I can spend my disposable income on "bike stuff" so what happens is that in replacement for actual riding time I "improve my bike".

But this concept bothers me somewhat.

I long for the time when I just rode the fooking thing. There is nothing like hours in the saddle eh? I think that this is a new trend in motorcycling, the relative expense, insurance premiums, difficulty in getting a driving permit, (in the UK at least), means that the age of motorcyclists is going up and up and so this trend of bikers who have no time but plenty of money to spend on performance bling is going to increase.

I want to be out on my lovely SD every night, every weekend, every spare minute I have. But it's just not possible. So we spend out time discussing upgrades on this forum and scouring Ebay for the next bargain for a bit of go faster kit.

It is a paradox that I do not know the answer to.

so i saw a lof of interest from you guys i though i would be alone on this,the thing is that in my opinion if you are going to do such a job you have to do some haeadporting as well and maybe change the exhaust valves with the sdr ones.I have already contacted a German company regarding the headporting and they quoted me with 650 euros for both heads using a flow bench but with the quote is with the standard valves, http://supermoto-umbauten.de/755/Zylind ... lerie.html

p.s i bought before staff for my ktm lc4 640 from the gwracing company and the gains were really good

So is there much HP to be gained with the cams and pistons without any other work?

I woke up thinking about this. In my old Ducati life in the past, once you start adding high compression pistons or over boring etc, you usually start to also think about stronger con rods to deal with the extra forces involved.

Otherwise you end up with fragile engines.

I take it the bits bored out of the pistons is allowing some extra CC's?

clearance for the valves at the top of the stroke, the extra height of the piston is what increases the compression ratio.
13 : 1 is quite high, but depending on what cam timing is available you can run a high static compression ratio as the overlap between inlet and exhaust valve open time keeps it lower it in real terms.

Quite true,, fast gas also required,, balanceing the crankshaft comes to mind as well ,then the clutch, in all its a "hog it out and hope for the best"scenario,, its a lot of work, you could get it right the first shot, but could be not,, in all it would be a more finely tuned piece, but it takes much fine tuning,, can't help but think some reliability would be lost as well,,
