    HELP!!! Hesitation, engine light, now no power.

    So today I was returning from visiting my sons at college. I was riding about 85-90 on the interstate and suddenly the speedo dropped from 90 to 20 and the bike started hesitating.

    Oil leaking from chromium cap in top left side of engine?

    In this area (red circle) I see some oil (or other liquid) marks. Question: what is covered under chromium cap? Might be some liquid leaking from this place? What it is, as I do not find any info in service manual?

    Engine color

    I’ve always heard that the grey or silver engines were only in the 04 and 05 years. yesterday I saw a 07 posted for sale with the light colored engine. When I questioned the guy he said it was a 07 purchased like that. Any ideas?
  13. Is revving up bad for R3R engine?

    hello R3 owners, I am wondering if revving up engine at 5500rpm to make louder sound by exhaust when bike is not in gear and not in motion bad for engine? Something like what this guy is doing in video but at higher RPMs. If its not good then what could happen to engine if you do it often...

    Engine Code P0315 error - SOLVED!

    So I loaded the Penner tune yesterday with TuneECU, it loaded fine. I am not sure which version of the instructions I was reading, but it talked about resetting the adaptations, which I did, and now the bike is throwing a crank position code, P0315. It also threw a cruise control code, but the...

    Engine breather pipe

    Good morning people. I have had my 2014 Roadster with 12800 miles on it parked up for 2 months and today noticed a very small oil patch on the floor which appears to be from the breather pipe under the engine. The pipe has an oil mist around it so i assume this may be just normal? I hav'nt...

    Once per hour or so, my engine seems to lose its power by half, starts making extra noises and rattles, and pops and backfires until I turn it off

    If I restart it goes away most of the time. Maybe I have to turn off for a minute or so. I just changed out the ignition due to the jiggle/off known issue. I also recently had it serviced at the dealership and now it drives crooked ever since I got new tires put on. This bike is posing more...
