Camshaft questions

Does anyone have the specs for the H2 and H2R camshafts ?

And also the camshaft upgrade that was announced in another thread, anything happening there ?

Thanks
Now thats very interesting
Real low cam centrelines for the intake even for the huge H2R cam
and conservative exhaust centerline on the H2 but way out there on the 2R

H2R ex cam specs up like the 08 zx10

When I showed these to Rich Sims, he had much the same comments as you.

So.... someone ask the the question they are dying to know?

The age old question?....

"What is are the best cam degree numbers for my _____ ?" (H2, ZX-14, Busa, aka modern sportbike - you fill in the blank)

My blanket response: "Is your engine stock?"
Them: "yes"
Me: "stock numbers"
Them: "but, I heard one-oh (fill in the blank) and one-oh (fill in the blank)"
Me: "It's still stock"
Them: "Yeah but so-and-so says..."
Me: "So and so can second-guess a multi-million dollar research and development team about the product they designed/tested and engineered if he likes. I have spent countless hours on the race track and dyno trying to 'beat' the stock numbers... I finally got it through my thick head, they know more about their engines than I do. It's stock."

Let the bench racing begin!

No disagreement here , over camming and wrong combos just wastes money

When i look at the H2 timing i see cams setup for torque , make it more usefull in the areas hurt by the low compression
they were shutting down the top end electronically anyway

Personally my aims are a bit different , Like Scott, Salt is my playground i dont care if i loose midrange as long as it can pull the tall first gear to the main power range
Ultimate plan is bigger compressor , intercooled , bigger cams ,E85 and probably a bigger bore exhaust
I want the bigger compressor over regearing the SC to keep the intake temps lower
Intercooler should be interesting , have a guy lined up here to do a billet plenum with Water/air cooler sandwiched between halves , and i already have front mount heat exchangers and electric water pumps from my Suzuki builds
Cams probably somewhere inbetween the H2 and H2R , thats going to take some experimenting , timing probably around 108-110
and if it makes the HP i hope the range of available exhausts is probably too small , but i dont have enough experiance in NA/SC stuff to understand what my exhaust needs are yet
E 85 is giving me great intake air cooling on the Suzukis, i see a 25C drop between the plenum and intake valve (EGT in port) , but will probably need an upgrade of pump and injectors
Thats the mad plan anyway , i think 250mph is within reach maybe more , depending on aero improvements

Oz, may be coincidence but I wonder if the post I saw on the Facebook H2 group yesterday is your project. That post included pictures that mimiced your description. I no longer can find that post on Facebook and now believe it was yanked.

Don't suppose you could share pictures of your project or if it is the Facebook post, share what happened to it?

Thanks!

I saw them,not mine though apart from the first pic in the set of several was my sheetmetal plenum on my road bike busa as i was building it
rest were RCC i think , but could have been from any one of several others that produce them
Same concept and i would not be surprised if there were others being developed
Water/air coolers while heavier than an air to air are about the only option when room is so tight
they dont hold a real lot of water , about 2 litres , pump draws a couple of amps , and a few braided hoses with anodised fittings brightens up the look

My H2 (second hand) was supposed to arrive today, but held up in shipping , now mid next week ,
