Interesting you say this, ive heard someone else say this to as long as i didnt go past 8k according to their theory. I can drop my 8200 rev limit down to 8000 since i dont need to rev past 8k anyways, do you think these fp1x cams would be safe spinning up at 8k on stock head for any negligable amount of time. Its real easy to bounce of the rev limiter around corners and on the slaloms in autox.
