What would you gain by fitting 1000 inlet cams to a 750?
Are the cam profiles different between the two or is it just the same cam fitted to two different models?
:cheers
I had a whole bunch on here years ago. I'm sure they are gone by now. Dont have those dyno runs on my computer anymore an it's been years ago. You wont see much gains on the 05-08 1000 and I'm sure no one will posted them as they dont gain much from cams as those motors are really just cammed out 01-04 1000. Busas and 750 you will see the most gains from. A busa can put up 15hp from cams very easy. Did you know the exhaust cam on a busa has less lift then the stock 750 exhaust cam?? yes in deed
The 1000, there is not much to be gained but you do get some thing from a set of cams it wont be anywhere the types of gains a busa cam gets. They have big cams already. More lift the a stock Busas.
why do you think a 05-08 1000 make about 10 to 15 more hp then the 01-04 1000..? Bore is only .5mm bigger. that wont do it! it's the cams and the head man.
the 750s, well there is afew people that has cams in there bikes. Most dont spend the money on motor stuff as 1000 bucks can get you a 1000 motor.. or they dont have the know how to install the cams and dont want to pay some one to do it for them. Cams are expensive for sure and then you have to pay some one to put them in for you if you dont know how to do it. Then you still get beat up by the 1000 so whats the point?? thats how most people see it. But I did 3 02 750 and every one of them made over 13 hp more dynoed a week apart before and after the cams. Don't believe me?? call my dyno guy and ask him Rayn Schnitz at shnitz racing. he will still have the dyno charts from the 750s I have dynoed.
136hp on a 02 gsxr750
138hp 02 gsxr750
143hp gsxr 750 with a 2mm overbore
What did the graphs look like before and after? ie. on the 750, did it kill the low end to make gains on the top, did it enhance the mid and the top? Would like to know more, thanks.
there was a gain from 5,000 and up. mainly top end. but I used a small intake cam. with a bigger intake cam there would be more of a gain in the mid and lowend as well.
It is an accel line, but here is the proof lol. Balls to the walls after 5k unk
Slashed lines are stock cams
Solid lines are 06 1000 cams
Both lines are with eall other mods, just different cams. The new line is before I really got into tuning as well, so A/F ratio was not 100% ideal. The curve is even better then this now (I'll see if I can find or make a new line)
Ok, I've done some reading on this cam swap business and I'm just about sold on it. (especially after seeing prices of the yosh cams. Yikes!hmy) I have a 2005 750.
But I want to be crystal clear before I try this. So I have A few questions about this. I hope that you guys will help me out on.
I'm reading that the intake from a 05-06 1000 is the best year to drop into my bike?
How about the indexing of the cams?
Is my assumption of being able to just drop the 1000 intake cam in and lining up the index marks and running it correct?
In moving my intake to the exhaust side, what is the procedure for indexing it? Having the mark 180 out?
I have no desire to smack valves off piston heads. I’ve done that when the timing chain jumped on my 70 cuda. :gaah What a mess!
barrracudaboy you need to get adjustable cam sprockets and have them degreed in and check the clearances. get a thin head gasket while your at it and a manual cam chain tensioner.
I have a K3 1000 and just had some K5 Camz Installed At 105/105 and while I never got it on the dyno Cause I was riding my just bought K5 , I would Say There's More Power Sooner Which Is AweSome How Much Power Is Up To The Total SetUp I did a driveline change to so it pretty noticeable With the Light 520 running gear RollOn Power IS STOUT
You can run a 9.5 and even 10mm intake side of a 04/05 600 safely (with hc pistons).
You would just need 01-03 steel 750 valve springs with the titanium stock valves in the 04/05 600/750.
I went with the 04 1000 Yoshimura cam set for the 05 6
I see a lot about putting the stock 600 intake cam on the exhaust side and a stock 750 or 1000 on the intake side.
However, I believe you need adjustable cam sprockets when placing an intake cam on the exhaust side. So, for the sake of simplicity I would just do a set of in/ex 1000 cams. The stock exhaust cam is 8mm on the 1000 and the stock intake of the 600 is 8.4mm but you do not need to get pressed on cam sprockets.
