I love how these vibrations occur at the exact moment when it's least practical/safe to diagnose them. I can just picture some asshole riding down the street going 45, with his head cocked sideways and his ear to the dash.

- Will check vacuum hoses (don't recall what's on this bike in that respect).
- Will pull off and clean throttle body. Hmm ... no syncing needed with only a single barrel. (The symptoms feel like badly out of sync t-bodies, I think.)
- I guess would not hurt to check plugs ... oh, and air filter.

I wonder if the dealership wrote in a new FI map when she brought it in for rear-wheel and instrument cluster warranty replacement. Anyone heard regarding maps for this bike? Anyway to reset?

Anything else? Cheers.
My bike had a surging at 4k rpm that went away when I replaced the chain. A bad stiff link can make it run like that but I was at 18k miles. Quick and easy to check though compared to everything else.

Hmm ... I will check the chain, to make sure all is lined up. They replaced that and the sprockets when the rear wheel was replaced. Thanks.

Steering Damper

Anyone try one of these on their GS?

I hear its really handy in the dirt and there is a group deal that someone posted for the Ralle Moto RM2 Steering Damper for BMW in the vendors section that seems like a deal... wanted to know if anyone tried in on the G650 and how they liked it.

Cheers

Look the Heidenau Scout K60, really 50/50, good look, durability and performance in all terrain.

I just bought a Heidenau, The Honda dealer (no BMW dealer close by) gave me a good price, got it in overnight and will be on the rim by tomorrow. Pretty good service I would say.

You could expect up to 5 hp, but without the oven underneath you melting plastic. Your mileage rate should go up incrementally as well.

Being well tuned can match the cat design: it was a half baked idea, especially for motorcycles. Energy is wasted evidence by the oven heat, that could be directed towards useful performance.

Your problem on your model (I have the carbed F650ST model) will be tuning the efi, which is razor tuned to a BMW oem budget. You may not be able to tune an efi any better than what you've got, unless you get a single delorto carb with a DS650 Bombardier 2 in 1 intake manifold ($20 off ebay used).

http://www.dellorto.co.uk/merchandis...rtsectionID=20

The above carb was on a 1997 KTM Duke 620 rotax with about 55hp. Delortos are the easiest to tune and the highest performance available. EFI is impossible to tune except a very tiny window (not enough for ANY 3rd party vendor exhausts without pops and backfires and performance degradation).

Of course it may work, but I would not count on it. I wouldn't even count on tuning the vacuum stock carbs. The original butterfly carbs like delorto are the only reasonable chance for a good bottom to top throttle range and good gas mileage (when not getting it on). It will only cost you $30 for a tig weld job to find out, but you may scrap your exhaust which cannot be beat by 3rd party vendor exhaust in performance (maybe weight savings, but performance first).

What I'd do would be buy an used oem exhaust system off ebay and try it first. You may not have to do anything except get a used exhaust and a $30 tig weld cat removal. Good luck!

I loved my Heidenau K60s for all around greatness. Fared me well coming in to corners hotter than expected, on reasonable climbs with loose mud/dirt, gravel, and rocky climbs. If you're planning on running mud bogs all day I wouldn't suggest them... or a G650GS for that matter. Other than that I never found them to be a handicap to my off road or on road riding. Some people have complained about performance on wet grass but my bike never sees any sort of terrain like that. They are $20-30 more a piece than the TKC80s but my rear lasted 6000 miles and my front still looks new. I just switched to D606s for a good chunk of dirt/mud I have coming up. Otherwise I'll probably be sticking with my K60s for the life of the bike. Perfect do it all tire for the perfect do it all bike.

Edit: Just saw that you went with the K60s! I hope they treat you as well as they've treated me.

I paid 180.00 for the tire and 30.00 for the install(cdn). Very fair deal!

I just put a K60 (140/80 17) on mine. $150 for the tire and a tube and another $30 for the install.

I almost went with the stock size, 130/80, but figure the sold center strip on the 140 will be better on the road where I spend most of my time.

Now, does anyone know the torque spec for the axle nut? When I tighten it down the wheel gets hard to spin, but when the wheel isn't hard to spin the nut doesn't seem tight enough. This may be one of those times where going by feel won't do.

Thanks,
Eric

74 ft/lbs- source: Riders manual, be sure to check your chain tension while your at it, I would think the difficulty in wheel spin would indicate that your chain is too tight

That's a good price, where'd you get them? I'm trying my first set of K60s. I didn't think about using the 140/80 17".
We should compare wear since we are starting around the same time. I should have mine next week. I usually get my tires from Revzilla but am open to suggestions.

There is a place local to me, he hooked me up with a military discount, regular price was about what you paid. Didn't have to deal with shipping. I think they are a distributor. The only thing they had on the web site was old school scooter helmets and aviator goggles.
