d207gp, is that an 05/06 Gixxer? Cause previously the 2 types of bikes I narrowed things down to was the 05/06 GSX-R1000 or a 08+ CBR1000RR. Then I came across this 07 and was kinda in shock.
noahb, I've got to believe that keeping it under 11,500 RPM would still be absolutely thrilling.
Nickj321, I never claimed that I could properly rebuild a motor. I had a few thoughts on this whole topic though... If it's truly 14:1 compression at sea level atmosphere and air density is roughly ~3% lower per/1,000 ft, then the motor will never see that high of compression if I kept it in Colorado above 5,000'?? (Technically it would, but it's starting and finishing density would be less.) I will mention that the builder said that it was properly plated, I can't member what type, but it sounded like that link you sent.
I'm an engineer, not a mechanical engineer though. So I'm more asking then telling. I could believe that altitude makes no difference on compression ratio, but I thought I'd ask. I know it does have an effect on lower horsepower though. I know you can even run lower octane fuel at higher altitudes without knocking/pinging.
Here's what I've observed in loss of power with altitude. I bought my friend an 08 1000RR with a carbon slip-on (he paid, I picked up) and thought it was fast. When I got a chance to ride it at about 700' where he live it was insane. I shit you not, the thing did a 2nd gear power wheelie, I literally started giggling with joy. He had added a PC III though, I can't believe it made that big of a difference.
Also, the first time I rode my 94 1000RR in the mountains, I thought my bike was broke. We went from 5'000' to 10-11,000'. It was so slow and weak, I thought it was time for a new bike. When got back down it was back to itself.
So, how much would a rebuild cost from a shop (maybe I could get a slight discount from the original builder)? Could I simply throw in new lower 3 ring compression pistons? Are the cylinder walls toast after 2,000-15,000 miles? What about just doing a straight engine swap at rebuild time?
I came across this last night. Made think 14:1 is really not a good idea. http://honda-tech.com/showthread.php?t=1801701
Keep in mind that all superbikes have higher compression ratios comparatively to cars and are reliable and also produce less than half the torque figures.
