Uneven firing order

jose_jimenez · 08-18-2008, 05:37 PM

There are some rumblings coming about the new Yamaha and possibly the Suzuki having a 1-2-1 firing order. This would be a forward step in production technology.

smoothrideronli · 08-18-2008, 06:53 PM

What is the significance of that for those who are not engine savvy?

CBRVFR · 08-18-2008, 11:10 PM

I had that on my SV once - it went 2---2----2----2----2. I love production technology.

Uneven firing of the inline 4 engine. A vtwin motor goes 1-2-1-2-1-2, one piston hits, then the other. An inline engine, the pistons fire at the same time. A big bang motor staggers the firing order of an inline 4 engine. The effect of this is better traction, the tire hooks up better, more drive, kind of like a Vtwin. What this would do for a street rider, is give them a more rideable power delivery of such large HP. The side benefit is a killer exhaust note. I've been jonesing for Yam to do a production version of this ever since they went to the big bang firing order. Some people in the N/A motorcyle industry are hearing these rumbling about the new R1. We'll see. It's been discussed that the M1 uses 2-2, while a production R1 would use 1-2-1 for more reliability.

All is not lost. In spite of the OP's utter massacre of the subject matter, it is a very interesting topic. Fortunately there are a lot of articles and forum threads running (complete with accurate information) around the internet with which to "reclaim" your 90 seconds...

I've spent a lot more than 90 secs on this topic and I still don't understand it for shit.

Yes, but your newly enhanced proficiency with MicroSloth Excel should catapult you into the stratosphere when it comes time to do your weekly TPS reports...

Dewd...let's not talk about this anymore. It led to lots of sleepless nights last time.

My current intellectual project is much easier, going back through my calculus book.

So... does a "long bang" L4 give the same 2nd-order vibrations as it's screamer cousin?

I used to be a "long bang"...

They have pills for that.

Some of you should lighten up. Every year we enter the silly season, riders changing position, and speculation on new motorcycles. Unlike the auto industry where we know drivetrain, HP, design, spy shots, etc, months and sometimes years ahead of production, bikes are kept under lock and key with everyone left guessing. People with ties in the M/C industry get information first, sometimes correct, sometimes not. Is it a crime to discuss this? No, but for some people they act like their boyfriend isn't paying them any attention in response. Last year was a good example, concerning the Honda twin, and favorite needle sticking topic. I posted it originally, and in the same paragraph said we might not see it go into production, no guarantees. The comments since have been priceless, and a joy to read. Bunch of grumpy men, bitching and moaning over it.

As far as the original topic, please edumacate all of us and post up your infinite wisdom on the subject. Lighten up Francis

Hey, he may embellish his insider connections but at least he's not very accurate.

Perhaps. But you didn't provide any links or credible or even published information. Even at that, your initial post was just a shot in the dark, particularly your comment about the current firing order of inline fours. You clearly have been around here much longer than I have, but in my short time here, I've the majority of the frequent posters to be very tech and mechanically savvy. So some specs on this would be neat-o.

Oh, and I'm not an old man ... far from it. I just like to see correct or seemingly correct information. But hey! That's just me.

Where are the rules that I have to do anything? People on here bitch when I post links, they bitch when I don't. They (not finger pointing at you at all) aren't happy no matter what and will complain about any speculation. They'll post up all kinds of bullshit off topic banter but you want to speculate about new motorcycles, racer contracts, and the like, well it's off with your head!

It's actually fun to toy with them as some of them claim to hook people with a lure or hook and enjoy it but they bite as hard as the rest of us.

Motorcycles and the racing of them are behind closed doors business. These factories are as tight as a frog's ass. There are rumors of a V5 VFR, patents filed in England for it, now there is rumblings from some people in the N/A industry about a big-bang motor for Yamaha. Is it a crime to discuss such things? Some people on here act like talking about this stuff, on a motorcycle forum, is blasphemy, or they act like you just kicked their boyfriend in the balls. I heard this info from another forum, and googled the source since you requested it.

2009 Yamaha R1 speculation continues, big bang engine rumored - Hell For Leather

Apparently the magazine MotoRevue is one such source on the topic. Just like MCN, purely speculative at this point.

Baketech · 08-19-2008, 08:46 PM

Just to be clear, it's not the prognostication I have a problem with...quite the contrary. It's a great topic and speculation is one of the more entertaining facets of online forums...

My comment was directed at the technical inaccuracy and descriptive butchery.

Carry on...
