Pretty sure everyone just goes dual intake. I would think the Gen 2 cams would be a good upgrade to a Gen 1 on the cheap. They make more power up in the rpm range.

Anyone know if combined stock gen 1 intake with stock gen 2 exhaust if its a good idea?

I already did it on na motor but to know if its a good option on boosted application or switch back to gen 1 exhaust camshaft
I can say this much. When I first built my engine back in 2009 I was interested in the 2 intake cam mod but a engine builder told me the it will make more horsepower with two intake cams but the engine will loose some torque so I just kept the stock cams, oh and I have a gen1 as well. By the way I'm curious about the gen2 cams as well. Hopefully someone will respond with some info
Well if u compare a gen 1 ex cam and a gen 2, there’s a big difference. A gen 2 ex cam is pretty close to a gen1 intake cam, in lift. The popular swap is the dual intake on a gen1 but bcuz of that, gen 1 intake cams are like 150, but a gen 2 exhaust cam is like $60.
The swap isn’t as popular in a gen 2 bcuz the cams are already good, u don’t gain hardly anything.
The other thing is the lobes are slightly off when moving an intake to the exhaust side.

Hi. DME gave my motor combo to Webb cams so DME and Webb worked out a custom grind for me. You can not just open the Webb cam book and pick out my cams. Also I do not think my cams would work very well in most other motors. As my red line is 13500 RPM

Well yea we talking close to stock and then your wild motor, but technically your cams would work in any head/valve combo that was ported to match those characteristics, it’s all just math.
Just wanted to include all info
Na it has nothing to do with degreeing, if u look close you’ll see the lobes arent perfectly centered over the buckets. Kinda nitpicky but a few ppl (frank included, who y’all love) swear it’ll spit a shim.HEHEHEHE Lobes are never off when you degree them correctly Poke poke

I've used gen2 cams in a "gen1" turbo engine. The bike went 6.54 in the 1/4 and 228mph. (Not both in the same pass). This was 2 gen2 intakes I believe, although I have had gen2 in and ex in it as well.

I dont know about all that, but I have worked on a bike or 2 ;-).
I actually wasn't sure any forums were still around anymore.
Any questions at all about the setups I've used, I will answer. Need to get more people to stock with these stupid performance bikes, many have lost interest it seems. Not too many younger generation even looking at bikes at all.

So both Gen 2 cams will work in a Gen1? I am actually interested in the Yoshimura ST-1 cams in my Gen 1 but they are only available in Gen 2. I am not concerned about changing springs and degreeing them.

The gen2 cams will work in a Gen1. Bearing will need to be flipped around and the retaining ring needs to be removed. Cam pin on the Intake is offset ~7°. Not a problem with a standalone application, but may need an offset cam pin for oem use.
