What do you mean a SV set off at 3K and a IL4 at 6K guess You mean you rev up and slip the clutch?

Anyway there is no point arguing I guess, its rare you have a razz of the lights and the difference is not great enough to matter in real world.

Either way Lloyd shouldn't have got left.
Its not realy shorter is it, only compared to a IL4 but remember the IL4 still has more revs than a SV and it revs up quicker.

Its higher geared and engine has more torque at any given revs than a IL4 at the same revs, if the SV was geared like a IL4 the bike would only do 25mph in 1st gear.

A ZX-10 has loads of torque, its gears are set so it will give near to 90-100mph in 1st gear, still does not mean it cant beat a SV.

ps. I saw you changed your post and amended what you said

TheGr33k spoken the truth no doubt...if the weather is good and the same situation presents itself again, I'll take onboard everyones advice and give it a go.

Thanks all for your comments, agreements and some disagreements.

Be Good, and Ride Safe

Just do it progressively when you do. i.e dont grab a massive handful of throttle, just wind it on, till you get used to how it feels that is.

I edited my last post. I tried to show a comparison in drive force but it dont matter, I cant upload BMP files Its the only thing these computers are allowed to save images as... GRRR.

Ill leave it. I guess it dont matter.

Best way for me to explain is a person on a bike is in 1st gear which does 5mph. Then a person who has slightly stronger legs starts in 3rd gear cablable of 10mph. Who would get to 5mph fastest? Thats the comparison we are making.
Why compare diffrent gears, lets say both bikes are in 1st gear.

My legs are already moving double the speed of yours before they touch the ground and they accelerate quicker than yours as they are smaller, yours are large and heavy and run out of puff earlier.

Ok granted I was a little aprehensive of giving it full beans, but it only seems to want it from 3rd onwards - plus the groan from the engine over 6K is a little loud.

I do have doubts that it might be restricted still, just can't afford to take it to a garage and fork out £200 for a check-up, just to be sure.
£200 pound well spent i'd say 33 bhp up to proper power, oh and there is a mod for a few bhp more in 2nd and 3rd on the engine management ignition timing, its connected to the gearbox, Ha Ha! have fun.

Do a check on the motorway for its top speed. Once you know that then it should not cost more than £100 to get it converted to full power. Even less if you know the right people.

I know where your logic is getting a bit mixed.

A 600 has more power and can rev higher, I give you that. Its not that that matters. 1st gear on both bikes are practically the same; So At 3K rpm the SV and the SS600 will be doing the same speed. At 4, 5 ,6 etc all the way upto the SV hitting the rev limiter the two will be doing practically the same speed at the same revs give or take a few MPH. Thats just how they are geared. So if the bike are doing the same speed say 30 mph and they are both doing the same rev's say 6500 rpm and they both open the throttle the SV will pull ahead momenterily because it is making slightly more power at those rev's. That is up until about 45mph when the 600 gets the power advantage and pulls away as the SV has to gear up...

Now what your trying to compair is the SS600 doing 6k rpm and the SV doing 3K, with standard gearing the Sv will be doing half the speed. Say 15mph while the SS600 will be doing 30 for example. Now Below is what you are thinking:

If you take the 600 and make 1st gear hit the limiter at the same speed as the SV does (about 48mph I believe) then at 30mph the SV will be doing ~6500K rpm but the SS600 will be doing ~9300rpm. That means that because the 600 is reving more its making more power at the same (wheel) speed and so would out accelerate the SV by a long way.

Does that make sense? Your trying to do the comparison of two bikes with first gear being the same. (my lower example) when in real life its the top example.

Hope that shows what im getting at... If not then forget it, its such a small difference its not going to be massivly noticable and both bikes get past 40mph so fast the 600 apears to have no disadvantage at all and pull away once they are past 40mph.

Cheers


Hope I haven't earnt a ban ha ha
