I have a 2003 R1 and i am curious if it is possible to raise the rev limiter on the bike. I have put in some YEC cams and now the thing is still increasing in power at the rev limiter.

All the 03's i've ridden do...:dundun:

And to the OP, I would think you'd need to have a YEC ECU. I don't know of a way to bypass it without one. I don't think a PCIII allows it.

12750 on the dot every time.... taktaktaktaktaktaktak of in induced misfire


Forgot to say.... do you have uprated valve springs in with the cams? i wouldn't go looking for more revs unless you do :)

:lol yep, it has a rev limiter that can only be increased cheaply with a kit yec ecu. and make sure you have kit springs in there too.

get powercommander, then buy ignition module, sign and fax form back to dynojet and they will send u software to raise rev limiter..but not recommended without working on motor first.

I have the yec springs on the bike as well. I have a PC3R that does fuel and timing. Guess i'll check with powercommander. I missed out on a yec ecu and harness cause i would lose speedo and odo, but now i wish i would have got it cause the bike pulls incredibly hard even when limiter kicks in, dyno graph shows power still rising.

I contacted power commander, they can extend the rev limiter if you have a pc3 usb not the r version i have. Figures. Shaved, your right it is there for a reason, in stock trim you aint making any more power, and second is rod bolts are likely to stretch if turned too high

Yea I don't have cams but I make my most hp of 137 at 10,771 rpms.redlines at 11,750 i think.And my most torque of 73 pounds at 7,000rpms..Unless you rebuild for it to handle it i wouldn't even mess around with the rev limiter.

Does anyone know if the 07 R1 has a rev limiter? i was racing a 08 gsxr the other day and when i looked down in top of third gear i was at 14,400 rpm so i shifted... If it does have one where does it come in at?

i have searched but cant find an answer thanks in advance!!!!!!
