Ok I have been having a problem with my GEN 2 since changing the exhaust.
When I am riding cold or hot weather every once in awhile my GEN2 will drop RPMs from 4500 - 5000 down to about 3000 - 3500. It's like getting whip lash all of a sudden and when you are cruising and don't expect it, it is quite scary. It was only happening in 4th gear at about 75/80 mph no it is happening in 5th gear at 85/95 mph too. I've tried it in high gears to keep the RPMs low and work up to high to try to replicate and to try to see if there was a pattern. No pattern and extremely difficult to replicate. Bringing it up to MO it got worse. I know what your thinking climate and gunck in the filter right? We took the fuel filter out and found nothing(that in mind on the gen 2 this is 1 piece now, thought I could change out the mesh thingy) That piece isn't cheap although if it is the cause I will dish out the funds for it. the last time it happened was two weeks ago while on the highway in 4th gear at 80 mph in a group. Usually I can down shift and slow the bike and then continue on(this time I was able to do just that) In September when it happened I had to stop the bike, shut it off and then continue on after a 5 minute rest. I can continue for about an hour or two before it would do it again. I bought the bike in FL and took it to MO. Right now it is in FL where it will be staying as I'm moving back.
I have an M4 full System exhaust that has been powder coated. Once put on it seems that every once in awhile it will just drop RPMs for no reason at all while riding. A bit scary since the bike seems to slow, body(me)keeps going. Makes me think my bike is trying to buck me over the front of it. Make sense
Ok so far it has been dyno'd and that shop put a racing map on my bike with the assumption I suppose that I was going to race my bike. That map was replaced with the correct map from M4 for my bike.
two people have been able to replicate the issue and it has taken them forever for it to happen to them. One was the mechnic who put the correct map on it, the other way my ex-husband. Both of them got the scare of a lifetime they said. Really duh.. try it from my perspective.
The bike does have a Power Commander III on it. I have not ever tried to connect to it as I really didn't know how. (I am willing to learn with proper assistance standing next to me)
I have changed my levers to the FP levers and changed them back to stock to see if that was the issue(someones suggestion) Nope did it with the stock levers too.
I don't know if it has thrown a code, no one has ever told me. The mechanic has had it for about a month or longer right now and in his down time is trying to replicate the issue. Good Luck with that. I do have a video with the sound of what happens.
My Questions:
Throttle bodies adjustment?
New filter? AIR & FUEL?
Put stock exhaust back on to see if issue is still there?
Connect to PCIII to see what I can find out?
Stand sensor?
Mapping?
Spark plugs?
What do you suggest? What are your ideas?
Any help, any ideas, any insights are welcome at this point. I'd like to also find out myself for the satisfaction of doing it and learning.
At this point my confidence in the bike is wavering. Makes it hard to ride. My gen 1 never did this. I want it back to normal and want my confidence back without having to give up my bike like a lot of recommendations.
All else fails I could turn it into a show bike..
Edited:
I still have the full exhaust
I do not know how to edit the ECU
I have not been riding the clutch
