I recently purchased a 06 R1. Let me tell you first, it does not run NEARLY as smooth as my 600rr by any means.

At lower RPM, like under 5k, when I am just cruising in any gear, the exhaust sounds like its popping or "gurggling". Do ya know what I mean? The bike has micron slip ons with no power commander. Also, the throttle response is not as smooth as my 600rr. I really want to figure this out, because it is very irritating. Even if you don't have an R1, maybe you can help figure it out. The valve train is significantly louder then my 600rr, and the cam chain seems to be kind of loose based on the noise, so I may have to change the CCT. Would a loose enough cam chain allow the valves to be a little off causing rough running?


My possible thoughts of which it could be: Exup adjustment, valves could need adjustment, TPS needs adjustment, needs a power commander to adjust A/F ratio

Any other thoughts? There is no reason why this baby should not be runnin smooth as butter!

Power commander wouldn't hurt, but if the cam chain is loose you would be wasting your time... if the valve timing is all over the shop then there is no way you are going to get a smooth idle.

I am going to check valve clearances this weekend. Also, just got some block off plates in the mail.

The timing wont be messed up by the cam chain becuase it has an auto tensioner on it anyway. The auto tension only wont work if the chain is really shagged. Might help to know how many ks its done and also how many since it was last serviced. The engines are normally smooth unless there is some serious setup issues with the bike. They dont have loads of power down low but go well once wound up.

The cct on these bikes is a POS and known to fail prematurely... when it does you get slight variations in cam timing that will give you an uneven idle.

R1s are funny at idle , def weird below 4k , mine [08]is nowhere near the silky beast the hoe7-RR is , valvetrain on them is loud and clunky, so dont worry about it, from R1.net, the failing cct are mostly on the 09s, and newer......get a powerC and tune the beast.

Yeah, the drive train is def. pretty loud. I have the stock pipe on my 600rr with 40k miles, never changed the CCT and never adjusted the valves and it doesn't make the slightest tick what so ever.
