I hit the throttle to launch, bike almost always wants to go left under hard throttle. Goes straight just fine when riding normal. Mainly happens from a dead stop, but through the lower gears under hard throttle even when I am moving it wants to go left. Maybe I am just imagining things, and I don't believe I am sitting wrong. Gonna do some more test runs before I take it into my dealer just to see if I am not imagining things. I literally have to hang off the bike just to make it go straight if I launch hard.
 
Mate take it to the dealer.

Is yours the bike that was on fire at some point?
 
Yep. Not sure what is going on now. I'll tell you what... I ride the piss out of this. I have 12,500 miles on it so far. I told my dealer they should make me a long term tester. Cause if anyone is capable of breaking it, it's gonna be me! lol Regardless that I do maintenance on it all the time. I am scheduled to take it into the dealer on Monday. They have to replace my turn signal switch, probably my rear brake master cylinder (doesn't even work and I don't use it, been bleed several times now by them, I don't even touch it.) Rear cylinder is leaking a bit of oil again out of the head. Only thing that sucks about this bike right now is the reliability. Yes, I know some of you have never had problems. EVER. But again, I run the hell out of it. Hopefully something just breaks and I get a free engine before warranty is up next summer.
 
What happens if you take your hands off the handlebars at, say, 60mph in Neutral? 60mph in 2nd under engine braking?

Could be the rear wheel is aligned improperly, could be the tire itself. Could be a bent engine from all those launches! ;)
 
Are the 2 allen bolts you loosen to adjust the chain tight? I'd guess something is loose somewhere and when you accelerate hard the chain is pulling it out of alignment.
 
I will do a few more test runs and which two bolts are you referring to? Thanks for the info guys! Not sure what is going on here. I will definitely have my dealer check this out. But I would like to narrow the cause of this all down by myself. I'll do a run with 60 mph in neutral and engine braking to see what it does. I feel like the bike is always leaning left too. Like I said, might just be my imagination but I think something is out of alignment.

It goes left during launch and the bike feels like it is leaning left no matter what I do. I think a speed test letting it go in neutral might be able to help figure out if it is really doing it. I am starting to wonder if I didn't hit a bump too hard and threw the front forks out of alignment :eek: I am going to take a tape measure and see if each side of the forks are at the same height. Plus they seem too soft, but no blown seal. I have to go get a professional suspension setup soon to dial them in.
 
i'd be very carefull on testing. If something is wrong, or going wrong and it still hase to blow up, you could get in serious trouble..

Standing behind the bike there are 2 large bolts just to the right of the rear sprocket, the rear brake and ABS line runs between them, I'd check the are tight first. There's a picture of them on page 214 of the (UK) owners manual.

Torque setting?
 
I asked this previously to my mechanic,,, 25 Nm (19 ft lbs) with grease on bolt threads, tightening sequence is 1-2-1.
 
Torque setting?

Tight! I'd say 35nm is probably correct. You need to tighten them alternately until both are correctly torqued.

If the bike has been pulling to the left because of this then I imagine it would be obvious they are loose - would be interested to know if this is the problem.
 
I would first make sure you're equally distributing the weight on each foot. You can do this by getting a little bit off of the seat an neutral when rolling, hands off of the bars obviously.

I don't think it will be uneven weight on the pegs. When you're next out try an experiment - stand as best you can with all your weight on just one peg and see what happens. Provided you don't move the handlebars, the best you'll achieve is a very slow drift to one side.

Is it possible/easy to mis-align the rear wheel with a single sided swing arm?
 
I'll have to give my dealer a ring to see what the torque is on the swingarm. Never hurts to check. I'll try a few things you guys mentioned. Didn't get out today. Probably be out tomorrow.
 
So I called my tech. But I would like to check these with a torque wrench myself as well. Both are supposed to be 25 NM. The rear swingarm bolts (2 on the back of the swingarm next to the brake cables) and the brake rotor (???) I am not sure where the brake rotor is to be honest. Can someone explain it to me or take a picture of it? Much appreciated. I looked it up in the spare parts manual, hell I used to fix $1.5 million howitzers, but I feel like a dummy because I can't figure out what he is talking about. Maybe it is listed as a different nomenclature.

Went to the drag track yesterday and I am almost 100% positive it isn't the way I am sitting. Although my shifter is seized so I can't adjust it. But I confirmed it wants to go left through almost every gear. I have to hang off the side of the tank, just like if you were trying to take a right hand corner to get it to not go left, in which case it goes straight, doesn't actually come back right. Again, I am taking it to my dealer monday and they are checking that and doing some warranty checks as well. This bike loves to break a lot. Not sure if I may keep it honestly :( I love this machine like no other. But I don't want to have to fork over $$$ to be paying for things that keep going wrong after my warranty is up next year. It's just a thought. I will try to let my dealer have a chance again of sorting this out, as they did very well when it caught fire a while ago. Also, what is the torque setting for the sprocket hub bolts?

Watch this. It makes a cut for the center line, then you can see it slightly coming back right. At that point I am fully hung off the right side of the bike. Its the same on the street too or especially when it wheelies.

Your brake rotor is the silver disc with holes drilled into it. Basically it'd be a good idea to tighten every bolt attaching the wheel to the swingarm and the swingarm to the 'frame'. And I'd be careful giving the bike full throttle. If something is loose every time you accelerate hard you're stressing something that's probably not supposed to be stressed. Would hate for a bolt to snap from constant abuse and send you down the asphalt on your butt....

I concur, get it looked at ASAP and take it easy until the cause is identified.
 
I am scheduled to take it in monday. So I will be having them check it then. I would probably guess the right hand pivot since it wants to go left, would be loose maybe. Even when it isn't windy, the bike feels like it is leaning slightly left when I am cruising
