2v 1000 budget cams??

Thanks nessism, ill look elsewhere then.
That's what you said about the 550 and 650 cams, which completely transformed the bike's powerband, and it's also what you said about doing the 650 top end on the 550, which completely transformed the whole machine.
The difference in the 850 and the 750 is dramatic at higher RPM, and the difference mechanically is that the 850 uses the 1000's lethargic cam timing, and the 750 does not.
Not everyone worships the stock configuration for everything as you do.
To the OP, try it and see, it's easy to do and might just work wonders.

I put a set in my Gs1000, I degreed them at 106. The top end was crisper and seemed to pull better. Would I do it again? Yep, Jerry

Well i see them on fleebay for around 30 so ill probably do it with adjustable cam sprockets just to see

Probably that with the d port 1100 head pods jet kit and 4 to 1 is my plan for this year
Four degrees is big, eight degrees is huge, but what they are not saying in those specs is how the cam timing is set. A few degrees one way or the other will completely alter the characteristics of any engine. Another thing you would want to compare is her far the cam opens the valve, and the slope that it opens and closes them.
But all the technical mumbo jumbo in the world is useless without a test ride, or perhaps a dyno pull or three.
I haven't put a 750 cam in a 1000 yet, but it's the first thing I'm changing when I get the new 1000 engine in the old 750.
I have the parts for it sitting on the shelf, there's no reason not to.
Are you going with the 1100's pistons and cylinders, too?
That's the current plan for my 750 once the 1000 engine is in.

Ape lists a 75 mm piston set for 1100's, makes it an 1146.
No and no. The greater cam duration will shove the power band up the rev range a small bit at the expense of low end and mid range. 4 & 8 degrees is minimal though so no big deal. At most you are talking about 1/2 horsepower. But hey, knock yourself out.

And i have a dyno so there will be before and afters

Probably not this year unless something major happens. I was also wondering if the 1100 g crank would work in my 1000g because going from a 64.8mm stroke to a 66 and there are 76mm pistons available would make an 1198. Although i dont believe id want to street it at that point with how i ride but i definitely want to increase displacement either end of 2017 or early 2018 so idk

I just want to get the basics done first though no rush
Can't wait to see them.

Me either, im waiting to do a run untill i get parts coming.. cant wait! If i get close to 100whp with those mods thatd be sick
The stock 1100G makes something like 92 hp at the crank. To get 100 hp at the rear wheel you are going to have to do more than just bore the cylinders. Most likely you would need a header, pods, and I suspect some proper hot rod cams. Rapidray would know. Steve (supertrap) built his GS1000 into a similar beast but I'm not sure if he ever put it on a dyno. He should be able to provide some pointers though. Sounds like a fun project.

All of thats on the list right now except boring, see my previous posts. Close to 100 is my goal so i wont be disappointed if i dont hit 100 lol
