Vibration in new 08 much better

[pehler]

may buzz point was at 4000 real bad...around town I would shift around 3000 to avoid it.I have changed my co # s to 14-18-18-24 and things have smothed out a lot! The buzz

point now starts around 5000 and is lot less,I find myself running it up to that a lot now!

Kevin

Please forgive my ignorance, co #'s?

Same problem here. Opening which gap?

As in Carbon MonOxide...unburned hydrocarbons.

European FJRs come from the factor with software adjustable, per-cylinder CO adjustments.

USA models can be "hacked" via The Barbarian Mod (search for it) to allow USA/North American models to be similarly adjustable.

So using blk_hole's example, assuming he increased each cylinder's setting by 7 increments, his "stock" CO settings were 7-11-11-17 respectively, cylinder 1 to cylinder 4.

Many FJR owners have found that increasing the "factory" CO settings by a factor of +7 for each cylinder leads to smoother idle, improved throttle response, diminished surging and Middle East peace.

It really means CO. Did not think it was adjustable. I will search for Barbarian mode. Thanks very much for the help.

I also have a 2008. However I have not noticed a excessive amount of vibration. My throttle bodies were not as perfect as I liked when checked at 5k and so they were readjusted.The horrid BT-2x tires were both replaced and newly balanced tires added to a nice smooth ride. A interesting thing I noted off topic but maybe somewhat relevant as vibration can come up for the tires . The independent shop I take my bike to one fellow had a SV650 with the same triangular wear pattern on his front. He was of course using the same BTx tire as the we get stock. He was complaining about vibration. Granted it is a different engine , but he was going to swap his for another tire , as he felt it would improve his vibration issue,

Unless at the track, if you are above 4000 in 5th gear, you are dangerously breakin' the law. Your choice to do so and put yourself and others at risk, but a choice usually reserved for those with less than stellar judgment.

So.... You never ride over the speed limit on your FJR? If you are serious, you are condeming a lot of your fellow FJR riders on this forum.

At the risk of hijacking this thread, I'm gonna havta go ahead and agree with GPRider. Talk about WRONG CHOICES! Don't understand the need/desire for an FJR if your gonna putt. Scooters and Cruisers serve that purpose for a lot less money. Could it be a STATUS thing? Do ya think you're a better Rider on a performance oriented machine?

I wouldn't call it poor judgement. Speed limits here are commonly 110KM/H with regular rate of traffic flow at 120. I believe that you are statistically safest around 5%-10% over rate of flow. 4000 RPM on my FJR is only 120-130KM/H (75-80MPH) which for a bike of this size and stability seems completely reasonable to me.

pehler, I did my plug change this weekend. Put a fresh set of NGK Iridiums in it and surprisingly my bike is less buzzy than it was. The buzz is still there at the same RPMs, but it is noticeably better. Now if I could just figure out how to mess with the CO adjustment.

I'll let you know if I figure the CO out this week.

Buried in RadioHowie's post is mention of the Barbarian Mod to allow changing of the Carbon Monoxide (CO) levels. He mentioned searching for it...

Here is the easy way to find all you will ever want to know: barbarian jumper site:fjrforum.com using the GOOGLE search function for this forum.

That search returns pages of discussion related to the modification.

Good luck!

While I haven't looked up and acutally read up on this, reading and doing are two different things. The procedure has been around about as long as I've been on the forum so I have read bits and pieces about it over the years. Seems like I remember reading that the Gen I and Gen II are a different animal when it comes to doing this. Howie has a Gen I, I have a Gen II. Howie, can you elaborate on this? Meanwhile I'll do a little reading up on it.

Even better.....CLICKY for Gen IIs.

Well I just read all that, then read a lot more about it. Very interesting. The only reason I had for doing CO adjustment was because I thought it might help get rid of high pitched buzziness at certain RPMs. According to Ionbeam. It will not help with that. So, back to square one. Looks like PCIII may be the answer whenever I get the disposable cash for it.

Who da hell knows. I just know it's buzzier than the old 04. (Here comes the GenI vs. GenII agument again) Ha! :lol:
