R1150R QUESTION

DIESELPOWER · Post by **DIESELPOWER** » Thu Sep 07, 2006 11:13 pm

Ok guys I am new here and I hope this question hasn't been answered in previous posts but here it goes.
I just bought a 2002 R1150R used with 14,000 miles. I love the way the bike rides but have one concern. It has a flat spot between 2000 and 2500 RPM Once past this RPM it is perfect. I am not sure if this is a characteristic of the bike or it has a problem. Any input or suggestions wuld be greatly appreciated. Thank You. Joe

You might be detecting a bit of surging, since yours is a single spark.

No flat spot on mine...

Is the bike stock or does it have aftermarket exhaust or air filter? I know modifying the flow of how it was designed can change the way it feels.

I've got a 2002 R1150R at 12000miles so - snap!
No flatspots and will pull from 1000rpm on the flat with no hiccups or flat spots right through the rev range. No, I do not make a haboit of it, just forgot to change down one day.

I have no way of merging the two topics.

The bike is completely stock. I pulled the air filter and plugs and they appear to be new. Throttle body's need syncronizing? I may take it in to BMW and let them figure it out.

i don't know that my bike has a "flat" spot or not. but it is far better performing bike when above 3000. i try to keep the motor spinning at very least 3000. well, when not at stoplights.

DIESELPOWER......forget about the fuel filter for now, too early and is also a pain in the arse.

Do a TB and Idle speed sync, see what that does for your problem. If corrected, I will just look at the plugs and the air filter, not knowing the prior history of the bike.

Good luck, let us know how you make out.....

Might be surging, might not. I agree with other posters; the bike should never be below 3000 RPM, except in neutral to first and when stopped. Babying your baby can hurt your baby... waiit a second, what did I just say?

Anyway, try spinning it up like that, I think you'll be more pleased.
