i guess the view is suzuki have all the foundations in place, but type approvals means having to destroy the power to meet emissions.. USA die hards think unlocking all the Euro 5 crap means a high revving drag motor anyone chump can take to the track and be an instant hero with launch control and run a 9 second quarter

are the carillos lighter than stock - they look heavy but strong

i copied this off another forum in response to Chris moore vid, the author is a tuner and gives ideas forwhy it happened and improvements by tweaking... Welcome chris, I’ve enjoyed watching you slay the track the last few years. I can’t help but laugh thinking how fast the pst guys are now in comparison to the top fuel bikes. All that tire and wheelbase, and y’all are within a second of those guys now on a dot tire.I myself started to do a video very similar to the one you just posted going over the detailed info on the revisions to the new engine. Then interpreted it to what it means to me in the aftermarket world. Just like you said in the video, I’ve been telling guys on here, and on all busa fb groups that I’d bet money that the G3 will have a high percentage of hp gained vs a g2 with the same mods.So since you made that video, I may as well cut loose All the things I noticed about the new engine. I apologize in advanced but it’s not too often I get to geek out with a fellow advanced builder and tuner. And the guys on this site really appreciate really technical stuff. So with that said...You covered servals of the same things I was thinking. But let me toss this out there. So suzuki came out with a redesigned set of cases to improve oiling 53%. Aside from dips in oil pressure from fast 60ft’s, and lack of oil returning back to the oil pan on land speed bikes, I’ve never considered the oil system on the other generations to be a weak point. Speaking from my automotive side of experience (mostly LS, SR, and 4G63 stuff) typically you don’t see excessive oil system mods unless the engine is going to turn unusually high rpm... hmmSo, major oiling improvements, and then the crank, pistons and rods have all been lightened up as well. We know that a lighter rotating assembly will spin up faster/be more responsive. Yes a, lighter rotational mass won’t wear bearings out as fast. But all that also lends its self to being able to rev higher as well. (I swear I’m going somewhere with this lol)Im really interested in the new exhaust camshaft. It has more lift, and both cams have been retimed to reduce valve overlap. I’m excited to mess with that cam in boosted applications as when you look at aftermarket or customs cams designed for turbo applications you’ll typically see they generally have more lift and not as much duration as you’d see in a NA or nitrous combo. I’m willing to bet those cams will be worth their weight in gold in a few years on psychobike when guys start wrecking and parting out G3’s. As far as the new cam timing “that has been updated to reduce valve overlap and boost low to mid rpm range engine performance” I think we can revert back to previous generations to see what this means, and how it affects the G3’s hp numbers.So suzuki constantly brings up the low-mid rpm improvements with the G3. Looking at the dyno graph suzuki posted you can clearly see it has a much broader torque curve, but peak HP happens sooner in the rpm range, and falls off faster then the other generations. This interests me very much as I’m betting simply re degreeing the camshafts on the G3 is where we’re likely going to find a big power gain.For example on the previous generations you can replicate that same dyno chart by advancing the exhaust cam and either leaving the intake cam alone, or retarding it a few degrees. (Referred to as spreading the centers) That will decrease valve overlap. When you do that, you’ll see the engine produce a much broader tq, and hp curve, but with the sacrifice of overall peak power. Definitely going to be some big gains there I would think.And for what it’s worth I’ll add this in. From tuning cars through their factory ecus that have variable cam timing you’ll notice that they’ll “spread the centers” sometimes for fuel economy, but mainly do it for emissions reasons. See what suzuki did there?Lastly, the improvement I’m most excited for is the new cylinder heads combustion chambers.pic from suzuki Australia: The “updated twin swirl combustion chambers” is basically something called un-shrouding the intake valves. Reworking the chambers like this is common practice in the LS, and Leads to 5-10hp gains just by doing that. Doing that allows for the fuel/air mixture to stay conical as it flows over the back of the intake valves and reduces the turbulence created when the mixture bounces off the cylinder wall. This helps keep the fuel atomized and a more complete burn is the result of that. But if you look a little harder you’ll notice some other changes. There’s more chamber work done to the area between both the intake and exhaust valves. It may not be so obvious in that pic, but the area around the spark plug is recessed in to the head more as well. It will be neat to see the gains from the chamber improvements in conjunction with addressing cam timing, exhaust, tune etc.But now look at a pic of the actual head vs the G2, and you’ll see the chambers are vastly different. You can see the chambers on the new head have a much more pronounced spherical shape to them. Does Doge Hemi come to mind? The new head should really shine in nitrous/boosted applications.The G3 has the same 12.5:1 compression ratio. We know the bore and stroke are the same between the G2 and G3. But assuming the cylinder deck height is the same as the G2, the compression ratio would be a lot lower with the g3 head, on less the pistons are different. And they are. Any time you remove material in the combustion chambers you’re effective making them bigger. (More volume) the only way to get compression back up is to have a taller piston, or one with a smaller dish. You can see the difference between the two here. On the sides of the piston that run in lone with the wrist pin, you’ll notice the areas that are more pronounced in comparison to the G2. If I’m correct in my observations then that would mean the chambers are bigger. In boosted applications the bigger the chambers, the more air that can squeeze in, which means more fuel can be added which means greater power potential. This engine is gonna love boost... I think.Again Chris, sorry to write a book here, but I geek out of this stuff. I’d love to hear your thoughts on my speculations and maybe add to them. And my explanations here were intended for the members as I’ve found over the years they eat up real technical stuff. They’re not intended as me trying to big bobo you, or anything of that nature.My pipe dream assessment of the G3 engine is this. With all the lighter, stronger internals that more suited for a higher revving engine, cams that just so happen to be very well suited for turbos, and larger, more efficient combustion chambers, lead me to think maybe. Just maybe is suzuki setting the stage with this generation for a factory turbo model? Again, that’s a pipe dream that I generated since studying this new engine.

Gen1 with Gen3 Arse Gen2 with Gen3 Arse

haha Cant be once 3 restrictive cats are removed He said bigger exhaust cams just by looking at PC monitor , and 11% more airflow possible via airbox, as john says many are hoping for 40hp increase i have subscribed to his channel USA bikes are released June 21, UK bikes are here end of march. i am pretty sure DVSA MOT don't give a feck about motorcycle emissions. so let us hope a brave owner will let John loose on Gen3, maybe Madmattt's

so i watched it... what do you think John and Mika he is super excited.. lighter crankshaft up to date pistons and valve train. says with bigger air box, 8 injectors with downward baffle plates, aftermarket exhaust and that all important RBW remap what power and torque i'll guess at 194 rwhp and 114 lbft ???

my data of made up guesswork and trollism from 16,000 post of being on year how many man years of typing have i done

ah ok , i did not follow all, i will go check again

well it certainly will fit same soggy front suspension, that needs re-valving and re-springing like i did to mine

yes believe A member off here mentioned here earlier - i'm not flicking back through the 400 odd pages i'm surprised your not getting one together with 2 sets of panels and 2 sets of wheels , you seem flush with cash

right crazy pointless benchmarking 0-200 metres acceleration and 0 -100 Kmh Gen 1 7.1 secs and 3.3 secs Gen2 6.9 secs and 3.4 secs Gen3 6.8 secs and 3.2 secs https://www.bennetts.co.uk/bikesocial/news-and-views/news/2021/february/new-suzuki-hayabusa-2021 bullshit , how convenient to choose and pick data i'd like to see via mags 0 - 180 mph 0 - 1mile 40 - 120 mph in 4th (zzr1400 Gen2 = 6.1 secs) good indicator of wide torque

those were dark days indeed

john where is the comments from Japan about some Suzuki guy falling on his sword (jeez 400+ posts)

john where is the comments from Japan about some Suzuki guy falling on his sword

been on quite a few USA Forums and after 1 day ....these guys are convinced that by binning Euro 5 exhausts and unlocking the ECU they will release another 40 hp why the elderly japs said , customers tend to custiomise and there is a lot pf potential, also suzuki mentions in the hype "cam with increased lift "

i think 2017

yes, but you get paid more over there , you know like in Iceland where a Mars bars the universal benchmark cost a £5 Mars = horrible sugar chocolate bar We've just arrived in Reykjavik and staying self catering, so thought we'd pop to the shop and get some bits in. I'll try to attach the photo of what we bought...but was 12 items including eggs, bread, milk, Cola and cheese... this cost us £42!!! I have read some reviews on here about how much things cost, and that it wasn't as bad as it used to be, but this has really shocked me! It's 4 times as much as the same items would cost at home.

yes Mika he has that stiff neck again bear in mind that video was released prior to launch , chris may have assumed it would have 1441 cc etc not with a reduced diameter throttle bodies and mild cam no doubt the exhaust will be binned and he may well open the engine and tweak we shall see he has been bragging on Hayabusa.org how he will spank Ricky Gadson and the zx14r again we shall see

Martin my bike has done 99,355 i don’t think I would would get anywhere near £4K part ex I would need to sell the Carbon wheels And ohlins rear shock that would be the same price as the bike

I went to bed excited like a 5 year old on Christmas Eve. I woke up expecting a 6 milion dollar man, a GI Joe with the the kungfu grip, and an Evel Knievel action figures waiting for me. Instead all I got was a pack of socks and draws. You had one job Suzuki.

Hill hold, hope it can be turned off good point that Mick

Mika i pm'd you
