Hi all again, back to the fold (had the 2000 model when they first came out - sold it since the kiddies came along, now bought an 02 model cause I just can't be without my 12.)
Anyway, I've just bought this 12 2nd hand, it has 23,000k's (14,000mi) in great condition except... When I've now finally opened it up above 9000rpm I find the power just flatlines... theres still heaps of power, just nowhere near the rush that usually starts around that RPM range..
By Flatlines I mean it doesnt increase at all, and it doesnt feel smooth in case your wondering if the last owner modded it to produce all power down low.. on that thought I'd say its not a rev limiter either since it kinda surges and very slowly builds up RPM, just with nowhere near as much power as it should have.
I've ordered the compulsory K&N air filter for it, I'll pickup new plugs (which reminds me, this site favours the CR9EK-PA plug (CR9EKPA for searches) but theres now the iridium plug of CR9EIX available as an alternative, anyone used this?)
Anyway, back to the issue... have you any thoughts whatsoever on this? I'm thinking it would be air related (reason for the K&N) but anyone else have any thoughts?
Note: I havent yet checked the plugs, but I'm sure they're due for a change anyway (Id like to know the basics are all of good quality and working order anyway), oil I havent changed -but will this weekend- although the dealer said they gave it an oil change (and since I rode it without checking the oil clarity I can't be sure now as it would be dark oil already), and I've gone through two tanks of fuel from different sources with the problem existing in both fuels. No Power commander is installed, but I cant be sure if it ever was the only mod was an alarm which was taken off before sale (only noticed that since the rear indicators were spliced into I guess for the flashing of the indicators on arming/disarming)
Any thoughts???
Thanks all
