Hey gang. I'm finally part of this awesome family . Bought the bike with ZERO miles today, for exactly 10 grand (sans TTL, which I'll pay myself). My first observation was that the MSO (the original title from Yamaha to dealer) shows the HP at 148. WTF? Wasn't supposed to only have 135? There's no way Yamaha would put more HP on the title than the bike has, or it'd get sued... like it has happened before (and with other vehicles as well). So what's the deal? I thought US bikes had 135 and European bikes 150. Curious what's the deal.
Now, bike is awesome, but it has one issue I've never experienced this badly: Bike shudders A LOT when starting or accelerating from low speeds in 2nd (I'm sure it does it in other gears too, but didn't try it). Is that normal? The bike basically shudders with the engine pulses, so that tells me the main culprit is a very light flywheel (no inertia). Are all other bikes the same way? How do you tame that without having to start aggressively every time, wearing the clutch unnecessarily? Same thing when I approach a stop sign or something, in 2nd gear, like 10 mph or so (clutch out). Bike shudders badly when slowly accelerating again, so obviously not the clutch. Just want to make sure it's the 'nature of the beast', and the best way to tame that. Or maybe it gets better with miles? Hope so. At any rate, no 'whining' at all that I could notice, so a happy camper. I also started the bike for the first time, and it fired instantly. And no extraneous engine noises of any kind; just the normal valvetrain noises, and quite subdued, actually.
Have several specific questions about mods, but will start new threads to avoid rambling all over the place here. VERY HAPPY to be on a bike again, and especially this one. Thank you to ALL of the members here who helped with my decision to get this awesome machine. Take care, and hope to meet many of you in the future. JC
I’ve owned several dozen new bikes. Lol. In 2nd gear at 10 mph in a flat road, slowly accelerating is not lugging the engine. But I get it that this bike don’t like too low rpm. If I needed to accelerate quickly, I’d shift to first, obviously. But when just rolling a stop sign, didn’t think it’d shudder that badly. And no, never started in 2nd gear ever. Bikes have too tall gearing to pull that shit. Guess will try releasing the clutch quicker once rolling, bit it’ll shudder too. Unless I start with relatively aggressive throttle (1st), it shudders. But glad to read it mostly goes away with miles. Will check exact clutch play, and adjust if necessary (doubt it’s needed). And will downshift to 1st at lower speeds from now on. Seems like a fueling issue to me, but could be wrong. No bike is perfect, so not a big deal. Also glad at least 2017s are not as neutered as we thought👍🏻
10mph in second seems pretty low to me. My bike starts to lug at 18kmph or less in first. I made sure to stay away from that when I was breaking her in. Keep an eye on the rpm, these things idle at around 1200, at 18kmph in first my bike is doing around 1500rpm.
I was probably doing more than that. But my point was it just doesn't like low rpm. I already got the hang of it. I have to slip the clutch more than I like, but don't think will wear it out much more than if I didn't. I still never take off quickly, so clutch wear should be minimal. Until clutch is out I get on it. Or will get on it, since I'm in break-in, and riding it gently. Just doing lots of engine braking, to help seat the rings properly. Awesome machine. With a crossplane crank and even pulses, I thought it'd be smoother at low rpm than a regular I-4, but for some reason that doesn't make mechanical sense, it doesn't. Probably too light a flywheel. But the engine character is awesome, so an easily overlooked trait I'm already getting used to .
Yeh it was the same for me man. My z1k would do 7kmh on its own and have no problems with it. Took me some getting used to with letting the clutch out fully, later. But break in is quite simple. I rode around normally for the first 400km then smashed it at 2 track days in a row. Seems to have worked quite well, puts down some nice figures. 10k kms between services and no visible oil usage, level stayed the same to my eye. No smoke, no weird noise. Great bike. Loves to be taken to redline.

After break-in I actually was surprised how easy this bike can start from a stop in 2nd. No shuddering or complaints but yet if I remember first gear to the rev -limiter is about 80MPH if I recall. For the changes made to the standard "R-1" configuration for a more street tractable set up it's perfect for me. You'll have plenty of miles of fun, just bring your gas card with you
