My R1 Thread :D

[insane79]

@insane79: The 09 R1 is coming soon.. maybe in a month or two. All the existing R1s have been sold off (nearly).

WOW thats awesome news, i thought they will get rid of the 08 model stocks first thats wat they did in 2008, they wre selling the left of stocks of 07 model + this way they get a change to pay abit less duty to the goverment, u have any confirmed source who told u this?? or its just a rumor?? If this is true its amazing news cause the 09 R1 kicks ass, one more thing u think the new R1 price will be higher cause of the $ rate increase

@rennycornelius: Please post the source of that info, it looks like a copy-paste job.

ya, it was a copy paste job......
but the original post can be found in the new issue of "BIKE" mag....it features complete road test of the 2009 R1......

dude pls...change ur helmet...dont spoil the look of the bike....get something better man..

[strider]

Akhil..
does that mean the buyers wont have an option, but to buy the 09 R1 Can the 08 version be still bought from the Yamaha dealer...

Hello !!
Reality check brother.. rossiter owns an Arai Corsair RX-7 : RX-7 Corsair

Im sure our bikes wouldn't fetch us an Arai in a trade

'Ahem' 'Ahem'....
Akhil, Are you listening???

[rossiter]

Yes...its been long. So the problems persist. To me, they still seem electrical in nature...probably something to do with non-legit inputs to the ECM from one of the sensors. No outright ideas from me either as of now. Check on the real basics though...like integrity of connections to and from the ignition switch, the tilt sensor and the impact sensor embedded up front. The R1 is a high vibration environment and that alone can cause loose connections.

Maybe cleaning the injectors and putting new O-rings will help. But that would be only if you'd got really bad fuel during one of your long rides. Hasn't happened to us as yet. But now that UP and Bihar are on...you never know.

Do get the bike up and running by the time we get there. Am looking forward to meeting you and of course, riding with you.

Update on the engine issue. Removed the ignition coils and got the plugs out last night. Plugs for #2 and #3 and #4 were in a bad shape. Had a sooty black insulator which indicated a very rich A/F mixture. This despite running with a cat con removed.

Anyway, replaced the plugs, but the issue still persists. Now it is going into the serious stuff. Planning to check the cylinder compression pressure, and also do a leakdown test. It will show if the cylinders are developing ideal compression and if not, where the cylinders are losing pressure, either at the intake or the exhaust valve. Maybe even at the rings, but that will not be the case hopefully. Keeping fingers crossed.

I believe this comment was posted in the wrong thread

I doubt that. Yamaha will only sell what they have, and they are specific about getting rid of the older bikes before getting the 09 in.

OMG. Are these problems a side effect of riding conditions in India (heat, fuel, dust) or because of the cat-con removal? Are all SBKs in India affected with similar problems like this, or its a one-off case? Cylinders losing compression! Cant imagine what would cause that....

Hope the bike gets up and running soon!

Does this indicate that the lambda sensor fed the ECU faulty O2 values leading to the A/F ratio being made rich..?

Precisely! Even I am baffled as to how an engineering marvel like the R1 is plagued by this serious issue(es)? What are the possible reasons behind this? Touring on different fuels, perhaps?

It might or might not be the case of cylinder(s) losing compression, but even then I am really curious to know how it all started Rossiter!? And is this by any chance covered under the warranty that Yamaha India is perhaps providing on their R1s?

[Aparajith]

Thank God Akhil got the official R1 and Yamaha is attending to it in the best ways possible. Can't imagine ur plight if it were a grey-market one. Akhil's buy has been an eye-opener of sorts to most people planning an SBK and those still undecided between grey-market or legal ones!!!

Hopefully the issues are resolved asap. All my(our) wishes to you for the same Rossiter.

It could be a factor. Like OF said earlier, our running environment is quite harsh. But I seriously doubt that it led to this problem. It seems to be a one-off case. But we will revisit this point after the problem is solved

And I only mentioned the compression test to check and see if the cylinder(s) is/are losing compression. It's not a confirmed thing yet. But I am slowly running out of possible causes.

One valuable clue I got was the condition of the plugs. So it's one of the first solid findings of the whole thing.

Does this indicate that the lambda sensor fed the ECU faulty O2 values leading to the A/F ratio being made rich..?

Even if the lambda sensor fed the ECU faulty values and turning the A/F into a rich mixture, this problem would have gone away when I put in new plugs. But it didn't. So it's not the lambda sensor.

OT: Good to know your Zma is better

It all started during my Southern India tour in December, when after a refuelling stop at Namakkal, the engine started spluttering and knocking. The knocking led me to believe that the fuel was the culprit and it would have clogged the injectors. So, the whole thing started with that.. Cleaning injectors, replacing the battery, checking the electricals and ground connections, and now replacing the plugs.

It has been a long and frustrating diagnosis, but one that has to be done carefully. If it can happen to me, it can happen to others so it must be done right.

It would be helpful to just check with someone else's O2 sensor.

My local mechanic had faced a similar problem with another R1, same year model as yours I think. I told him about the O2 sensor check, he eventually did fix it but I'm not sure if the O2 sensor check revealed anything. I'm going to call him at 3 pm (after his lunch) and ask him what the problem was and what he did to fix it (it was electrical/electronic in nature).

Thanks Ariz, I'm open to all inputs at this point. Post up his feedback here if you can. I don't think it's anything to do with the O2 sensor, but I'll be very happy to be proven wrong in this case

[Haroon]

@Akhil. Its been a long while since I visited this thread.
Just saw your problem. Dont know if you solved it already.

I had a similar prob on my Dodge car a long time back. It also happened after a refuelling. Apparently after checking injectors, sensors etc, the culprit was the fuel filter in the fuel pump located inside the fuel tank that was blocked due to some residue in the tank (mechanic said, probably when the fuel is poured in with pressure, it agitates the settled particles and could have gone & clogged it). That way the vehicle will start etc normally but will sputter. Anyway, I still think & hope its a small problem that needs to be diagnosed properly. Good luck.

To me O2 sensor seems the least probable as I know bikes that have had their O2 sensors (in the exhaust) removed. Whereas the throttle position sensor or air temperature sensors may be more related to such a problem.
