My R1 Thread :D

[insane79]

Damn why do our state have high taxes .. Lucky you guys are 40 Rs petrol,taxes less, Leh very close.. Damn

OOps OT

well the R1 uses 97 octane fuel which is a very expensi in mumbai, ard 70rs a litre

welcome to xbhp bro

[rossiter]

thanks santosh, rossiter or if anyone over here with a legal R1(bought from yamaha India) tell me wat their rear suspension preload is set on?? the default setting no is -5, i want to know if yamaha india soften the rear suspension for our indian roads,
thanks..

The suspension is left untouched. They don't change anything except the mirrors and the horn on the R1.

Yam India know or care jackshit about setting up the bikes so I doubt they would have messed with it here. Unless it was changed at the country of origin, but I doubt that too as then the manual would be wrong.

Manual does have few misleading instructions, but at the same time, Yamaha India do know a fair bit about the CBUs here

I heard Yam is offering huge discounts to clear stocks.

It's inevitable, but hasn't happened yet.

Welcome, or Ni haow Mr.Eric1984

So, my R1 is currently grounded because of some misfiring and sluggishness off the line. I've been having this problem on and off ever since my December ride around Kerala and TN. But now it's not going away with even good 97 octane fuel. So one or both of two things could have happened IMO:

1) Injectors are clogged (Most likely, and also Yamaha's diagnosis).
2) One or more of the spark plugs are not working as they should.

Either way, I'll know in a day or two.

From ur trip log u mentioned that the issue happened after some bunk's fuel, right? Too bad!! Anyways, take care. And BTW is cleaning the injectors and replacing all the plugs such a tough job? Will it take a long time(2 days)?

Yamaha is giving a 75K discount at the moment.

Really? I was at Bangalore Wheels on Saturday and they had the same price on the price list put up in the showroom. Since when is the discount being offered? For both R1 and MT01?

Akhil, I suggest you get a substitute battery in first before going in for injector cleaning. The Yamaha people can do that for you. Sunny's bike had faced a similar problem (misfiring just off-idle, overall sluggishness, sudden shut-downs and occasional refusal to idle). The Yamaha people took it in for two days, cleaned injectors, installed new plugs, new air filter, recharged the battery and gave him back the bike. Ran well for just half a day and then back to the same issues.

I suggested they look into the battery issue and the Yamaha people agreed. The old battery did show up 12.7v (under no load) but probably buckled up under load, esp the high starting kick load. They put in a fresh battery and the bike has been running smooth since. We have also been using fuel from regular highway pumps (Speed, Extra-premium) and have done some 1800 kms since leaving Delhi. Except for some knocking just off-idle, all is well.

why are the mirors & horn changed?? hmmmn..

OF, could you explain a bit more about why/how this was rectified by the battery change? The injectors just got back from cleaning and there is no change. Still a lot of sputtering and misfiring going on at idle.

I want to check the plugs now, but I'm starting to think that it's a battery issue.

They are changed to comply to our Indian motor vehicle regulations.

Akhil, I may not be right here, but am just giving a wild guess. As we all very well know the battery is loaded the heaviest during startup and after that its charged while the engine is running from the coil. If one of the plates in the battery is faulty or the charge does not stay on the battery, then while running, the power might not be properly supplied to the plugs et al, right? More so in the case of ur bike where the battery has to run the electronics, headlamps, radiatiors and is heavily loaded. I guess that's what Old Fox means. I may not be right though. So correct me if I am wrong.

[mithun.08]

another wild guess, did the battery got damaged while we charged it back by the charger( when the bike was halted in aluwa ) or some thing went wrong because of the security system..

This probably has to do with the all-digital engine management system. These digital circuits are pretty sensitive to input voltages. A certain threshold trigger potential is needed to make them work without error.And as Aparajith speculates below, there is probable damage to the battery plates and it is unable to retain the charge resulting in a dropped potential between the terminals.

Again check out the earth connection on the engine block before even going for the battery substitutrion. A loose connection there or even a little carbon build-up could cause similar symptoms. (you know how easily these 12V circuits can be affected by even a small resistance between connections)The engine block earth point can be accessed by raising the tank. Check the wksp manual for the exact location. If you dont have one let me know. I will mail you a pdf of the relevant sheet.

Yes, a quick-charger can damage batteries, esp like the tightly packaged ones used on bikes like the R1. The inter-plate gaps are very small and a heavy charge current can cause vigorous gassing resulting in pressure build-up within the batterry casing that in turn can warp the plates. Even one cell shorted can ruin a battery this small and this heavily loaded.

The Guru has spoken...

Hence.. If The One that Sunny's using for the GIR2 had exactly the same issue, then it doesn't take much analysis to isolate the problem with Akhil's steed.
Chalk up another diagnosis for the OF juggernaut..!!

[rossiter]

OF, I am now completely convinced that it is an electrical/battery related issue. I was on my way to the pump to fuel up (add drastically reduced mileage to the list of symptoms), and I was still having the same issues. But while idling at a traffic signal, I heard the engine note change and the roughness/sluggishness went away. The engine performed flawlessly till the pump (3-4 kms away). But once I started up again, the problems were back.

The concerned people from Delhi are coming down next week to solve the problem, but in the meantime, I'll source a battery and try it out. The diagnosis can go on in the meantime

I have the workshop manual and I spent some time last night looking at the the wiring diagrams, checked the wiring for any grounding/ damaged wires etc. As far as I can see, it looks OK. But I'll be checking the plugs just in case.

Speaking of plugs, how were the plugs on Sunny's bike when they changed it?
