So now that a few have had their 2020 RR's for a week or more, I wanted to see what build / quality issues ( if any) anyone has experienced. I have a couple issues and want to see if they are isolated to my bike or maybe a more wide spread problem for BMW.
1. I am getting a "clunk" sound from the front fork/shock when rolling over small consecutive bumps on the road. It is most noticeable when I let off the throttle and come to a rolling stop at a stop light or sign. As the shock compresses and rebounds and absorbs the bumps it gives a clunk clunk clunk sound ( if you will) . It almost sounds like plastic rattle and I thought it was maybe a rattle from some plastics but discovered that is not the case. When I turn the ignition on and the suspension de-compresses ( if you will ) I can bounce the front end up and down and the clunk persists upon each rebound / compression. Just doesn't sound normal to me. Can you guys / gals be so kind as to bounce your machine front end up and down with ignition on and tell me if you hear a persistent noise upon each compression / rebound. It seems to be the left ( ddc side) making the noise but hard to tell. I just can't see it being normal on this machine.
2. Bike sputters and dies upon cold starts. It acts as if a cylinder is flooded or injector stuck open? Anyone else having cold start issues? after a couple tries , it seems to idle out and run better. I am still not sure if it is idling smoothly even after it warms up. seems a bit rough but not severe by any means.
3. Poor throttle response / power between 6-8 k rpm in 2-3 gear. Is this the emissions control doing it's thing? very noticeable and unacceptable as far as I am concerned. Happy to buy the $2k titanium exhaust but concerned with engine light being on. Flash? ugh . Anyone else noticing this issue between 6-8 k rpm? did it go away when the bike was "unlocked"? I wouldn't think so but fishing for an explanation.
4. The ticking and engine noise ( especially upon start-up) doesn't overly concern me yet until BMW says theres a problem. I read a couple threads about insufficient oil pathways due to a milling depth problem but honestly don't remember the whole story without looking again. But I will say that the sound mine makes upon initial start-up ( once it finally starts) is a lot different than the sound it makes a few seconds later after the engine is running for 10 seconds or so. I am no mechanic and apologize for the Layman description of what I am experiencing. Could be tight tolerances from a new engine? or lack of oil in the places it needs to be lubricating? Or nothing at all to worry about just normal noisy BMW engine.
5. I am scheduled for my run-in check / unlock this tuesday with my semi-local dealership ( gateway BMW St. Louis) and have described all the above issues with them already but honestly , I doubt they know anymore about this bike than most of you guys. Not knocking their mechanical abilities at all. They do great work and have taken care of me so far with all my purchases from them. I do know They had a couple training sessions but its all new to them as well so they really have nothing to compare my bike to which is understandable but scary as well. sounds like they may connect computers with BMW directly the see what its doing if necessary with regard to the sputtering on cold starts / injector testing.
I really don't want my new 2020 rr pulled apart for anything! I guess one step at a time...
But do Love the 3 year 36k warranty ( just in case)
Other than these issues , great bike so far. ( BUTT that M seat has got to go!)
Maybe I can try to upload some sound / video later? oh boy that sounds like a technical challenge for me!
Thank you in advance. I hope to hear from new 2020 RR owners on this and more.
I have 1480 miles on my 2020 now today. I have already burned off 2 front tires and on my 3rd rear today. I am pretty sure if it was going to blow up it would by now.
1> I do not have any clunk noise consistently. I think, I did hear something like that upon going over a speed bump once and it surprised me I heard it, but, just figured it was the speed bump causing most of it.
2> Mine does not sputter and did not any time during the break in miles either. I have run 2 full bottles of Lucas Fuel injection cleaner in my fuel as well. I wanted to be sure if there was any injector issues from sitting on the shelf or trip from Germany to USA they got clean.
3> The throttle response is due to USA EPA requesting some limitation on carbon foot print. I guess this is how BMW engineers decided to do it. I have talked with 2 people in the Europe coded ECU bikes that indicate it is not as bad as it sounds like it is going on with the USA coded models. I have the ECE code, and I have decided I will try it this next week. I am pretty tired of my dead spot in 2 and 3 gears for sure.
4> Those ticks. Sounds like a bad shim adjustment. Mine started at 400 miles. It was perfectly quiet up to 400 there about miles. All the sudden it was like oil was missing from the top end. I rode with 2 other ///M bikes today. See pic of all of us getting rest and fuel. One has only 150 miles and the other is at 380. Neither ticks as loud as mine. However, the one with 380 miles is starting now. @bennymx
posted he inquired about it with a rep and the short story is that the shift cam technology is making the noise. I really hope BennyMX can get the long version of this story. Like what the heck is loose and sounds like it is going to come apart. Mine actually stops if you Rev up the engine to 4K RPM. But the idle to 2-3K is unreal loud.
5> Even the DFW HP certified BMW did not know nor care that I had a tick in my engine. He said ride like you stole it and bring it back if it blows up. I did have them write on my service work order CUSTOMER made complaint about loud ticking in engine. Service Tech said nothing was wrong with it.
6> The seat is hard as a brick. I raced superbike for 4 years and I never used that stupid foam one layer pad on my race body kit. I like a real seat for my butt to sit on and be somewhat comfortable.
