Any info on what you did on the carbs? I'm doing a turbo on my VF750C which is very similar overall and have been trying to figure out if I need new needles in the carbs

@TheFlyingDuckTheory Ай бұрын

Just balance the float bowl pressure to the plenum. We used a pitot tube taken from the charge tube directed through the breather tubes and a variable (rising rate) fuel pressure gauge with the pressure tube taken from the plenum. The size of the pitot tube will vary depending on your area and jetting. I have an 8mm outer diameter tube with a 5mm inlet hole bored into the side. The needles are standard in my case and I am using 130 main jets. Nothing else has been changed.

i think this is BS yes you changed the firing order ie 1 will fire when 3 was suppose to and then 3 will fire when 1 was suppose to here (link below) is a reresentation of vfr (180 degree crank) firing instead of firing in a cross pattern now it will fire 2 on the left and 2 on the right, ie you just stuffed up the x balance a bit , it is impossible to get a big bang without taking the crank out cutting it and rewelding it in 360 fashion , that is according to stories where the rc30 comes from, a privateer team actually did this with a vfr750 and whipped the buts of the factory teams and then the RC30 was born or so the story goes kzbin.info/www/bejne/qou8f41-odOie5Y google the different cranks rc30 and other 360 variations you will see the two wide journels point the same direction and the 180 variations they point opposite directions it is techinically impossible to make a big bang by just rotating the cam that is exactly why we have wasted sparks ie 1/3 spark together but only one of them is on the ignition stroke and the other wasted , that is why the bike still runs when you do this since you just moved the ignition stroke to the wasted one and the wasted one to the ignition stroke also adding the 360 big bang notice how the two cylinders fire so close together and then nothing for a while because of the way the crank is built the 1/4 fire close together and the the crank has to go all the way around before those 2 can fire again hence the big bang, same applies to 2/3 kzbin.info/www/bejne/Z2KTqmuLa7OIq9E

2+2 =4, so does 1+3, so does 0+4. There is more than one way to create a big bang engine. Simply, given the fact that the RC36 is a 180 degree crank as opposed to a 360, there's no need to cut it up and reweld it, it already lends itself to the configuration. The ignition pulses are brought to 90° intervals the way I did it, with a firing order of 1-2-3-4. I don't know what the RC30 spacing/firing order is but I'm willing to guess it isn't any closer than what I've done. So you can call it whatever you like but you'd still be wrong.

@leondavibe Ай бұрын

@@TheFlyingDuckTheory i don't get what you think you are doing, the firing order is already 90 apart swapping one bang for another doesn't create a big bang ie you don't create a dead spot by rotating the cam on 180 you just swap which one is ignition stroke ie you swopped 3for 1 and 1for 3 Moving when the bangs can happen creates a big bang Rc30 2 cylinders fires close together ie the cylinder 3 fires then as that journal reaches top om 2/4 90 later, 4 fires then because the crank is 360 On the next 90 there is no piston that is tdc the next one will only be tdc again 270 later , thus the bangs have been moved creating what is regarded as big bang because longer break Ie the cams follows the crank if you want to change bangs or the space inbetween you must change the crank

@TheFlyingDuckTheory Ай бұрын

@@leondavibe@leondavibe I haven't made any mistakes. I have changed the firing order by utilising the wasted spark system. That's what make this work. Rotating the cams moves the original ignition events of cylinders 1 and 3 to what would have been the exhaust stroke so that it is now the compression/ignition stroke. It subsequently changes the firing order to bring the ignition events closer together in a regular 90° crank rotation pattern. It's as simple as that. Big bang doesn't mean all the cylinders ignite at the same time. It can, but it doesn't have to. In this case it just means there is a significantly short ignition sequence compared to a much larger non ignition period. As for no gain, you have never ridden a VFR with this configuration so how would you know? Stop speculating, ignorance is not a good look.

Unfortunately, aside from the early days when the VFR was used by the likes of Ron Haslam, Freddie Spencer and Bubba Shobert, very little development has been done on the VFR compared to inline 4s. This was the main reason I went the supercharger/nitrous route. Aside from lowering the compression, you don't have to modify the engine much for it to give good power. There may be different cams available for the RC24s if you hunt around long enough but the 36 onwards was considered more of a touring bike so power development was very sparse. The bike as it stands works well with standard cams so I see no benefit in changing them.

Hello and cheers Mr. Langdon. I‘ve got some questions about the engine. I‘m driving a MY '92 RC36 in Tasmania Green Metallic and I love this bike so much. But after I‘ve found out, that you made a Bigger Bang version of the engine (that‘s how I call it, because the natural state of the RC36s engine is already Big Bang), I totally lost my mind in rejoice. Now that I found out, that HRC uses the same crank as the VFR 750 F in the MotoGP, but with a configuration similar to yours, I’ve got more interested to convert my bike to the same specification. Now, after I asked some questions how to properly convert the engine to that firing order in the forum of the German VFR Owners Club, I got some messages, regarding the fact that the starter freewheel would crash because of the double pressure on the pistons and the airbox like the exhaust manifolds would need an adjustment too. Because I know, that you went already through all that stuff, I’m asking you: what beneath the cam gears on the rear cylinder bank have you changed on the engine and the bike? Kind regards and thanks in advance from Germany

@TheFlyingDuckTheory Жыл бұрын

Hi Johannes, thank you for your enquiry. Can I ask if anyone who responded on the forums where you asked the question had actually performed the big bang engine conversion them selves? I find that a lot of people dismiss ideas without ever having tried, or seen in person the thing they are rejecting. As far as the starter gear is concerned, there is no more pressure on it than on a standard engine. With the big bang, the ignition pulses are closer together but do not happen more than one at a time. The standard airbox is perfectly adequate for the running of a big bang engine as well. The only differences that were outside the engine was a custom made exhaust because the bike was constructed in a very non standard way but all engine internals were what arrived with the original engine. I used this engine for approximately two years in this configuration without any issues at all and the bike was used daily. I hope this answers you sufficiently. If you want more information please ask. Cheers.

@johannesk.6885 Жыл бұрын

Good morning and thank you for the fast answer. I think none of these persons did that conversion, they all wrote in a subjunctive way ("would crash”, "would need a new airbox", etc.) So, now I‘m more convinced to get this job done.

What would happen, if I would drive in that new configuration with a standard exhaust system (with a Remus Stainless exhaust on it)? Best regards again

@@johannesk.6885 Hi again. Using the standard manifolds would have no negative effect on the way the bike runs. You would still have the same jetting ratio of air to fuel per cylinder so the stock exhaust would be fine. If you are already using an aftermarket slip on silencer and the engine works fine with that then it would work exactly the same with the big bang configuration. The best part about this is that if you don't like it, you can reset the cams back to standard as you are not physically modifying any parts just the timing on the cams. 👍

@@jesuschrist-alphaomega I don't care about drag times either, but you're deflecting now anyway, you stated it was BS just because you had this same bike back in the day. But he has done way more to that bike than the stock bike you had so 9 seconds is perfectly doable, Don't comment stupid things in future...

@@jesuschrist-alphaomega it doesn't say anywhere in the video that it is turbo'ed and it won't. The bike is supercharged and uses nitrous oxide. If you cared to look at my other videos you would have seen this. My FB page Team Flying Duck Theory also shows everything that has been done to this bike. So no, it is not bs and I also have an ACU verified timing ticket to back up my claim. I am a member of the National Sprint Association in the UK and they are very strict about the timings. If you still doubt it, I am more than happy to demonstrate how fast this bike is, all you have to do is show up at one of our 1/4 mile venues and you can see for yourself.

Thank you for sharing, but... How do you manage the spark timing for the new ignition order ? Thank you

@TheFlyingDuckTheory 2 жыл бұрын

Hey, no worries. The spark timing is taken care of by the fact it is a wasted spark system so what was the unused spark automatically becomes the ignition spark.

With gear driven cams it is essential to align the silencing gear when tightening up the can bearing caps. If the gears jam you can snap the shaft

@TheFlyingDuckTheory 2 жыл бұрын

If you mesh the cam drive gears correctly, that will happen automatically.

Is this changing the motor to fire 2 pistons at a time? I am unfamiliar with the big bang setups purpose.

@TheFlyingDuckTheory 2 жыл бұрын

No. It makes the firing order happen in quick succession rather than spaced out as per standard. The purpose is to give a better drive out of corners, better torque delivery away from traffic lights (if that is your thing) and less fatigue on the tyre because it is getting a 'rest' between the ignition sequences. It sounds evil too. 👍😁

@TheFlyingDuckTheory 2 жыл бұрын

Unfortunately not. I will advise to remove the front mudguard (fender) first to prevent damage and either use a winch or engine hoist to help lower the engine in a controlled manner. Or at a push, a trolley jack underneath. The engine weighs 75kg on its own and is difficult to manage without some kind of assistance tool.

Either way, if you are doing a complete strip down then taking the frame off the motor is the way to do it. If you are just dropping the motor you can do it either way. You'll need another pair of hands though.
