Greetings K bike experts!
I rode home today on a 2009 K1300GT with 14k miles on the clock. The bike appears to be immaculate. The selling dealer says that all the recalls are up to date.
Does this include the cam chain jump guard thingy? Is that something that the 1300 engine needs?
I think there's a put of hesitation when I open the throttle that maybe can be improved with a bit of enriching. I like the way the AF-XIED lambda-shifter helped my R1100GS. Do you guys think this is likely a good idea, or is there something else I should be looking at.
I'd really like quieter airflow round my helmet at speed. Is it true that the (expensive) aeroflow is the right choice? If it is, I'd rather not waste money on trying a bunch of others!
Also, I'm still getting used to the various noises the bike makes. I do feel vibration in around 4000rpm. Is this likely normal?
Here are my responses to your questions:
* Cam Chain:
Yes, if all the recalls are up-to-date, then the cam chain jump guard should have been installed. If not, then your dealer was incorrect about all recalls being done.
* AF-XIED lambda-shifter:
Sorry, but I can't help you there. I don't know anything about it.
* Aeroflow AeroScreen:
I recommend it highly. It may be expensive, but it is definitely worth the money, and probably the best third-party windscreen available.
There is completely still air and dead silence behind the AeroScreen. When I answer the bluetooth phone in my helmet, the caller does not know that I riding at 80 mph - they think I am in the office. It is that quiet. I am 5 foot 10 inches tall and I have the tall Aeroscreen. I tried the standard size and the tall size, and prefer the tall size. When fully raised, I can just barely see over the top, which is exactly what I want. When fully lowered, there is some air flow, but not as much as the original BMW windscreen.
I also have the AeroGards, and recommend them too. They do a good job of deflecting most of the air flow away from my hands, arms, and shoulders. I remove them in summer to give myself more air flow. They are easy to install and remove.
* 4000 RPM Vibration
Yes, it is normal. My K1200GT has been "buzzy" between ~4500 and ~5500 RPM it since I bought it new in 2007. I feel it mostly around 5000 RPM and just live with it. I notice it when changing gears, but it is rare that I would find myself cruising along in that RPM range, so it doesn't bother me.
I hope this helps.
