My take on the surging. And what I propose to do next.

How about an idea from left field? You've all heard/ had a trouble code reader for obd1 or 2 cars. How about 1 for bikes?

The link is one from a company in england that makes one, but yamaha was not listed. They say to call for future applications, maybe the website was never updated and those interested will luck out.

This product is recordable while driving and downloaded to computer, giving sensor info, etc.. well enuf with the discription, read for yourself, see if it might help in your altitude diagnostics.

If they dont have a program for yami's, maybe theres another company that does.

Without further ado,,,, Link : https://www.probike.co.uk/it080002.htm

P.S. maybe it's snake oil,,,, I donno

P.P.S. just figured the recording might give some info at altitude problems

A PCIII does NOT fix the problem. Bike runs great until you start riding in the mountaings then the surging starts. I tried just about every map available and none made any difference. Yep, the bike sure runs a lot smoother ...until you get into the mountains. A PCIII helps mask the problem but doesn't fix it. I got tired of pulling over every 5 minutes and shutting my bike on/off when riding with a group. It doesn't take long until you feel you are the black sheep in the group ...on a new bike no less. Pulling over/restarting the bike is not an acceptable solution on a $13K bike IMO. Would people be content stopping on the side of the freeway in your new car or truck 10 times on the way to work to restart it? Or would you go home and pull the motor with a cherry picker and dismantel it to see if you could find the problem?

The surging appears to be worst on some bikes then others. On a scale of 1-10 I would say my bike is an 8 ...meaning it's almost unridable unless you do something (get out of the mountains or park it). It's not a hiccup thing here and there. Perhaps the overall climate coupled with altitude is what contributes to a slight or severe problem.

All this talk of reverse engineering the FJR FI system in order to fix a bike that should run correctly out of the crate is just crazy IMO. I guess there are the technical types that like this kind of stuff but I bought the bike to ride and enjoy ...not to use as a guinea pig in my laboratory/garage Why don't we get Yamaha to fix the problem? If they won't, do you really want to own the bike? Yamaha should fix it, afterall they engineered the bike and sold it at ~ $13K a pop. Reading this thread reminded me of the cartoon Dexter's Laboratory Carry on.

I'm with you tophog, but yamaha is thumbing their nose at you guys with the altitude problem!

I don't think Yamaha is thumbing their noses at us but if you think about it those of us who take our bikes up and down hills are in a minority for sure. I think that Yamaha is trying to figure it out and come up with a fix. If all the mental horsepower on this site can't figure it out why would we expect the folks that built the bike to magically come up with a solution in a week or two without riding the piss out of a CARB 08 FJR up and down Mount Fuji?

I gotta put my faith in the company. I think their engineers will figure this out, and it just may be that with the emmission restrictions that California and the Euro gang have placed on these "heavy polluters" that we ride that this is just the beginning of the end for all bike manufacturers. The next time you visit your Yamaha, Honda etc dealer you may be required to purchase California Carbon Credits to prevent Global Warming (or how to reverse an Interglacial weather trend).

It's late............. :dribble:

I also think they are, just by not ACKNOWLEDGING the problem. I'd be much more patient if I knew FOR SURE they're working on the damn issue.

And yes, all freaking manufacturers have the same attitude towards problems, so certainly nothing new. I remember my overheating GL1800; Honda did nothing for 2 years, until it was slapped with a class action lawsuit. And as revenge, it slapped us back with a frame rewelding recall (sold the bike at that point).

Anyway, hope you're a prophet man, and they're really working on a fix already. And don't be so apologetic to them; they have sophisticated lab equipment to simulate just about anything. Plus if they had tested the bike properly in real life conditions, problem would have surfaced well before production began. NO EXCUSE whatsoever IMO. Later.

This is not "performance" problem, like the R1's. People are reporting that their bikes are dangerous under unexpected conditions and Yamaha remains unresponsive.

This not only reflects poorly on Yamaha's quality but also their ethical standards. As far as I know, they continue to sell these bikes without as much as a warning to their dealers, let alone customers, even in mountainous areas. Is their communications blackout financially motivated, or is it just arrogance?

They're acting more like an HMO than a Japanese manufacturer.

I've been off the board for the last month or so and it appears that this problem has gotten worse. Just for the record, my 2006 has never exhibited this problem and my altitude varies with every ride (I live at 8600 feet), usually in the 5k to 12k elevation. Is the problem only at the lower elevation changes? If so, that is interesting -- don't know what it means, but interesting.
