Throttle by Wire

I see your point

Zen I see your point, this is my first V4, I come from a world of Vtwins, so I suppose I am asking a lot of a V4 with the tuning issues this thing has. You are right I need to be in a gear lower than the 1300s to stay with him, it will be interesting to see if I have to go down a gear with the Dam exhaust and the Bazzaz Fuel controller and 1st and 2nd gear de-restricter installed.

You would think Honda could get this thing running smoother so you could lift the gearing on it, cause the acceleration would be crazy. But to be fair this thing runs smoother than a lot of the Vtwins I have owned. Mate thanks for the graph I kind see it all now.

 

Hope you get the feel you want, think I know what you're talking about it being a little jerky at lower RPMs in 2nd gear have felt that a few times but I always thought maybe I was running the rpms to low. I tried for two weeks to contact Damm Exhaust without any luck that's when I went with the two brothers can.

 

The motorcycle magazines attribute the throttle jerkiness to excessive driveline slack. I don't have a 1200, but I test rode one when they first came out and I immediately noticed this, it bothered me a lot, it was the only thing about the bike I didn't like. I wasn't sure what the cause was, but I thought it felt like something that would/could be fixed in the next model year production. We'll see.

 

It's not drive line slack. Get on your bike click it in first get going (you can do this in 1st or 2nd) cruise in a low rpm 2000 maybe give 1/4 or 1/3 throttlle and when the rpms build you'll notice at about 5500 rpm it will suddenly accelerate harder even though you are maintaining the same throttle opening. That is what I'm refering to.It's not too tall or too short of gearing it's not drive line slack .It's a pre-determined power output by Honda .Maybe it's through electronics and fueling and or butterfly opening intervention by Honda or maybe it's the V-tec and how it is programmed. I tend to think it's through mapping.

 

Bro I can back up RWR, this is not drive line slack, the Honda has the least amount of drive line slack of the lot, you want slack go ride a BM and find out the difference.

 

V-Tec? This bike doesn't have V-Tec.
Clearly if the Z-Bomb can fix it it's electronic. The guys at Bazzaz must have figured out what it is exactly. Despite my experience in mapping and on the dyno I can't tell for sure how it's done.

I love the drive slack by the way. Feels like you have a chain. This is my first chain-less bike in 30 years so I'm very happy about the way Honda did this.

 

The bike was primarily designed for Europe or at least in Europe, like the Pan. Since we have slightly higher highway speeds (in my case considerably higher) than in Oz, and a lot less chance of being caught - I have a mate in Sydney who came over a few times to ride - the Honda is geared properly. However on parts where 100 kph is 100 kph, I tend to leave it in 5th. Feels much better, more responsive. 6th gear feels like an overdrive most of the time.

I don't ride with a K1300S, that might help. :smile:
I do ride with a Street Triple R. And even two-up, I can shake him wherever I want. Granted, might have more to do with the R's rider than the bike.
By the way, he's in 5th when I'm still in 2nd. Talk about short gearing!

 

You get the point. From what I've heard the Z-bomb is what we need.

 

What BS

What BS, maybe you should go ride in Moto GP gun.

 

Fair enough, I formulated it wrong: the guy - my bro-in-law - does very little riding these days. I guess the few times we ride together are the only rides he does. Pretty sure my buddy could ride rings around me on his Dorsoduro if he still rode on the road. It was more of a compliment to the Honda, not to my 'riding skills'.

MotoGP? Nah mate, I'm far too old to start racing again. :smile:

 

pretty sure the z bomb will just be an application of what Dutch gixxer has already figured out. The fix will result in a 3rd gear dash display in 1/2/3 gears. It will just be a plug and play, but they are having to buy a very large quantity of connectors,
and it is being delayed until October they tell me.

 

My 1200 does not "surge" under steady roll at 5000 RPM. My 3rd Gen VFR had a very noticable surge at 5000 RPM. There is a different exhaust note....but no speed surge. You are not gearing down to 1st gear for much other than starting the bike. The bike is ultra responsive ...almost too responsive past 3500 RPM. My first few rides I was talking to myself to watch the throttle note on bumps as the throttle was very sensitive. I completely miffed at the descritpions of flat spots or not feeling connected. Not what I am experiencing.
