A few impressions on the new to me 919

My new to me 919 has been sitting in the garage for a few weeks.
How can this be?
Piss-poor weather ( in california no less ) and waiting on a front fender ( I'm being a bit Nancy about looks ).

OK. Quick recap- Bought a 2002 919 with 4700 miles on it, completely stock. (Except missing a fender.)

So this wasn't exactly a trip thru the twisties, rather a ride into work.

a) The bike feels small. Tiny. I'm not used to bikes with no front fairing, and I think that's whats making me feel like the bike is small.
b) Is this bike for short people? Perhaps it's the slope of the seat, but coming to a stop, it seems like the ground is right there. (I'm 5'11, sorta average legs.)
c) The motor has a nice sound.... surprising really.
d) The low end of the motor coming outta stop lights is nice.
e) The low end of the motor coming outta stop lights... and sitting in the throttle for just a minute seems to lift the front wheel.
f) Repeat e

I enjoy a nice little wheely now and then on previous bikes, but the 919.... uh... this is silly. I'm not talking 11 o'clock high wheelies, I'm just riding a few 2-3 footers into the rev-limiter.

g) When accelerating hard (and not wheelying), the bars feel a bit like they're flapping. Perhaps I'm holding on too tight. Are tank slappers a concern here?

First, I'm happy you're enjoying yourself!

The 919 is quite peppy with the stock sprockets, I went +1 on the front sprocket which gives me more af an even feel throughout the RPM range, imho...plus equalizes the speedo a bit.

Since day one, I've enjoyed to feel of my 02 919 as it turns into a corner...it still feels very nimble to me, compared to my old bikes. I don't recall any flappyness going on, but I thought the handling improved a lot when I replaced the stock tires with some Michelin PR's.

Well, fire the engines! Spur this iron space-pony on!

Sounds like you are unloading the front end & its left to meander at the slightest imperfection in the road/your hold on the bars.

Right. And on some bikes ( I'm thinking of... say a Honda 929 ), that can result in a nasty tank slapper.

This happens a lot to me on full acceleration, and I have never had anything close to out of control or a tank slap. The 919's ergonomics don't seem very prone to a tank slap.

I've only experienced any amount of headshake when carrying a mighty load of groceries or when carrying fully-loaded sidecases and accelerating HARD. Even then, it self-resolved with little fuss.

You might want to check a couple things. Are your fork tubes positioned higher in the triples than stock (stock is flush at the top)? I've read 10mm will quicken handling with no ill effects but more could promote some "flappiness". Rear shock preload too high (insufficient sag) could also promote the same situation.

The forks look flush. The rear preload is at the 3rd step.

Let me say that this wasn't a horrible flapping feeling... just more like the bars were lightly wandering in my hands. And I was using full acceleration. But I tend to do that when I ride my motorcycles.

I left work a bit early last night and rode home the long way, taking a very twisty road home.
Calaveras Rd to Calaveras Rd - Google Maps

The 919 is an absolute peach on this road... able to flick from side to side very quickly, and the motor being smooth and responsive pulling out of the slower corners.
Everything you guys already know.

I like Calaveras--keeps ya honest and is fun on the 919. Fairfax-Bolinas, too, though my buddy on her 599 can wipe the road with me on that one.

Tank slappers are of no concern whatsoever on the 919. I laugh everytime somebody calls or posts up about trying to get a steering damper for the 919.

The lazy geometry of the bike pretty much precludes any need for stabilizing the front end even when landing crossed up wheelies etc... I've even romped the piss outta it with a slightly longer Honda 600 shock that raised the rear end & a 120-60-17 front tire that lowered the front and still didn't get any real disconcerting headshake that I can recall...

Fair enough.

I saw jesus a few years back on a 929, going straight... accelerated hard, skimmed over some rough pavement, and I ended up with 1 hand and 1 foot off the bike.

Oh. One more point.

It really seems to be missing about 500-1000RPM.

I have a complete stock 9er and have never had a problem with the bike wheelying on me at all, it must be the way you ride. I also probally heavier than you to, im 6'2'' 225 and the bike fits me perfectly.

I had a lovely squiggle coming out of a corner when playing in the hills the other day. But as per LDH, nothing scary at all, I actually enjoyed it.

Seriously though, I would love a steering damper and some swing arm blocks, and I would assume that there are about 3 others who would also. Going from 100-140 with 8 lbs of boost and a light front end and not really being able to use first gear over 5k are kind of down falls of the turbo system.

My 929 has almost 40,000 miles on it. Never a tankslapper. Some did, some didn't.....

Sounds like a fun problem to have.

a) Overall the bike does feel smaller to me as well. I switched from a 600rr. Only thing that feels different to me is the front end. 600RR basically had nothing up front, it did have a fairing obviously but flat out felt like there was nothing was there.

g) Again from the switch initially I though the same thing. It is just the different set up of the suspension. I can tell you flat out I landed a crossed up wheelie on both. Neither had a big issue no stabilizer is necessary

My '03 came with a TOBY side-mounted damper on it from the previous owner. Since it was already on there, I use it. 4-5 clicks on freeway speeds and just completely off when city riding in traffic. It's really long and will probably be the first thing to hit the deck if the bike goes down on its left side.

TOBY's COMPANY

Just wanted to add that I don't detect any changes in the way the bike behaves when it's on, but since its there I use it.

Ive had one good tank slapper once....all i did to cure it was keep the throttle pinned and shifted my weight to the front

I'm more interested in swing arm blocks. There has to be blocks from another bike with the same specs that would work, but I can't really find any information on them. I know I can just have someone cut and weld blocks right into the swing arm, but I don't know how much I like the idea of that.
