Headshake head-way

I have been trying to finally cure my headshake issue over the last couple of days. This followed after I did an ofroad challenge last week where I kicked butt in the Orange route portions, but then have everybody overtake me again on the link dirt roads. Even an X-Challenge could go faster than me. Headshake started at 105 kph. I could manage 130kph standing up. But I live in South Africa, so that will never be enough...

I thought that a couple of small improvements might be possible, I did not believe that a single break-through would be possible.

The 1st major improvement came I dropped the forks below the flush level of the top Trippel clamp. Its now recessed about 6mm. I was concerned about dropping it that much, but on the Ozzie 690 thread I saw that it was not immediately harmfull.

The 2nd result came after realising that an upwind run on my test gravel road caused more headshake than the downwind runs. I've previously read in the Race Tech Suspension Bible that unbalanced aerodynamics can cause headshake. I've messed around a bit with the hand guards and mirrors at some stage, without effect. This morning I saw that the massive snow shovel front fender was not aligned with the front wheel. Adjusting that cured my headshake after almost 13 months of messing with it. I feel a touch stupid.

The only 3 factors that affected my headshake were sag, front fork height and the fender. In other words the basics. Sag must be in the 70 - 85mm range. The sag for PDS bikes will not work. Adjusting clickers affected comfort and lines through corners, nothing else. Same with fork pre-load and oil level experiments. The Scotts steering damper could not prevent it on dirt roads either, even running the high speed almost complete closed and with sweep set to the max. It did help on tarmac.

Hope this will help someone.

6mos old, 7000km - valve train noise

So this last week I've noticed an increase in engine noise from my '11 ER; specifically from the top-end. I thought it time to have a look at the valve train. Knowing a tight valve train wouldn't really be noisier I figured something was up. It looks like I have a rocker needle bearing about to grind to a halt. Should I change these myself or have the dealer perform the swap under warranty?

Short clip illustrating the buggered bearing:

I'm with you, mine wasn't straight / aligned with the wheel axis. I think that the shape is more likely (as opposed to something like a motard fender) to create the dynamic imbalance that will allow incorrect chassis set-up to come to the fore as headshake. From my understanding 2 things must be in place for headshake to occur: incorrect chassis set-up and a trigger. The trigger could be corrugations, aerodynamics, whoops, strong aceeleration that gets the front end light, etc. The focus should really be chassis set-up, as the triggers are likely to be part of off-road riding.

I have ordered an windshield today for pickup tomorow that will be interesting if that stops it which is my bet I will post up after 130 kph test ride -seems bigger guys and bikes with windshields dont seem to get the dreaded deathwobbles

Does anyone know where to find the auxillary starter relay on an 09? all roads are leading to it as the problem for my dead starter. As I understand it the ASR ties the bikes electrical safety devices into the main starter relay i.e. roll over sensor, side stand sensor, clutch sensor) so that if all the right conditions are not met the bike cant be started....which sounds exactly like my problem!!.

Try a yamaha dealer, some of thier bikes use the same relay. My local dealer let me paw through the bin until I found one.

If you mean the actual location of the relay on your bike,
I don't know offhand but I'd go to one of the online parts
fiches like Munn Racing and find it.
I think I'll do that now, just out of curiosity.

I think the relay you are talking about is just behind the battery to the left. People have had some issues with that relay in the past. Sometimes just loose connections. Mine has had no issues after 3 years of ownership and 11,000 miles.

I really like the new Rally Raid tanks. Is the older 990 style headlight set up still able to be fitted? Not too sure I like the new lights look.

Yes the new kit will still accept the older 990 headlight and screen

That looks to be a function of the Tripmaster. Do you have the switch installed?
