Sure thing! I'm glad I can help out and spread some knowledge. This should work with any carb. The same concepts apply. Every fuel delivery circuit needs to be opened up the appropriate amount. Now... Some carbs are jetted lean from the factory for emissions etc. It's best to get a rock solid gasoline tune before you begin a methanol conversion. On the thought of using a 4 stroke motor, you need to remember that methanol is extremely corrosive. It will blow by the piston rings into the oil below and contaminate the oil. it will hide in the oil and corrode surfaces if left untouched. Now it's possible to get everything running very hot during the gasoline purge and that might be enough to burn the methanol off the oil and burn it off any surfaces the oil could have carried the methanol to... like the valve train. If you watch Cletus Mcfarland and/or Steve Morris his engine builder you'll see where methanol contaminated and corroded the valves, rockers, and springs on his 4k+ hp engine since he didn't purge the engine with gasoline hot enough and long enough. Same concepts apply here. Your oil change interval goes up and the gasoline purge cycle is much more important. Hope that helps!

The PWK28? IDK what carb the predator has on it. The PWK28 inlet/outlet dimensions should be on google. Measure you current carb/boot and go from there. You can force a slightly bigger carb into a stock boot if you have to. It's hard though. The 2000's 250cc 4 stroke carb race dirt bikes pretty much all used the Keihin FCR39. That's a 39mm throat. If your vavling/cam/porting/exhaust are near the performance levels of a 250 4 stroke race bike then a smaller carb like the PWK28 will probably cause some power restrictions. I can't say if the 28mm 2 stroke carb will be adequate or if the 39mm that all the 4 stroke race bikes run will be adequate. Keep in mind you will have to change oil a lot more frequently with methanol on a 4 stroke since the oil will get methanol contamination and can cause corrosion problems.

New here. I was surprised with few things. a) I read some place, they actually build some type of engine for methanol. I can hardly imagine that they have to clean the carburator with gasoline after each use. Or injector, whatever. b) The other thing is the ignition. Computers and programs. Come on, for a garden tool F1 garage? There have to be something with ears and eyes, I guess. Or not.

a. The only difference between a methanol engine and a regular engine is the high compression, ignition advance, and fuel injector/carb jet size. other than that it's all the same stuff. It's just a different fuel. The fuel is VERY corrosive. It'll eat through aluminum and rubber seals if left sitting... Hence the purge process. All engines that run methanol are required to do a high temp purge. on 4 strokes the piston ring blow by allows methanol to enter the oil bath beneath and it contaminates engine oil very quickly. The engine oil cycle time is severely reduced on 4 strokes. Not a problem on 2 strokes since there's no engine oil haha. b. You have to be able to adjust the ignition timing to maximize power output for methanol or any high oxygen content fast burning fuel. Simple advance/retard of a mechanical adjustment is typically not good enough. It's really not too difficult to learn the process. The unit comes from Ignitech Ignition. It's really cheap. The launch control is really fun as well.

Unfortunately you can't just mix it in a can and run it, methanol and gasoline won't mix together, at least from what I've been told by the folks at Sunoco. It may be possible that it can mix in the combustion chamber if you figure out a way to run a dual fuel system. I thought about it in the past and decided it was easier to just run straight methanol. Like maybe you could build a carb with a powerjet pulling from a methanol reservoir, so it only brings in the methanol at wide open throttle. But that almost requires a separate carb/fuel bowl + float just for a methanol system. No idea how you would jet something like that as well. It would be very hard to figure out if you were rich or lean as methanol doesn't do plug coloring like gasoline. The math gets super complicated quickly. You'd almost have to build the dual fuel system on gasoline with an inline main jet on powerjet and then do the math to upsize the powerjet system just for methanol. Very complicated work, but might be possible. There might be enough turbulence in the combustion chamber to keep everything aerosolized and ignitable. I've actually been thinking about running what I described above but with the methanol carb and nitro methane as the secondary fuel that only comes in at WOT. I don't think the ignition system will be able to cope though, probably not enough spark power.

Hi there, I'm a bit unsure what you mean by "diffuser" and "Pistonette" needle. The air flow amount doesn't change when switching from gasoline to alcohol, only the fuel mass changes. You shouldn't need to make changes to any airflow components like exhaust or porting etc. It never hurts to test changes to mufflers/silencer though. My muffler/silencer works best as a long straight pipe/stinger with no baffles. Make sure you aren't TOO rich. Too rich and it won't run well. When I first started I used a 230 main jet, it wouldn't run well so I decreased the size in steps to 215 main jet and that worked great. Also if the engine is cold it will not run right. It takes FOREVER to get the engine up to temperature with methanol. When I race the bike I roll around the staging area at low load and low rpm for 5 to 10 minutes to warm the motor to full temp. It takes a VERY long time for methanol to make the engine warm and the bike will not run right until it reaches operating temperature. For my carburetor I made sure every single fuel passage and fuel metering device had it's flow area made larger by about 2.3x to 2.4x bigger. Here's a screenshot of part of my excel sheet I used to calculate the flow area of the fuel that passes by the needle and the needle jet as the throttle slides up and the needle rises. This calculates that "doughnut" shaped area as the needle rises with the slide in steps of 0.1mm. i.imgur.com/piMu1NH.png I have highlighted the comparison ratio between new flow area and old flow area in blue. The flow ratio is right about 2.4x the flow area.

I hope this makes it more clear. i.imgur.com/SKSSJjW.png Focus on getting your math figured out. It saves so much time and tuning effort to determine the sizing by using math rather than guess and check tuning. If your needle jet flow area is too large compared to the needle diameter your needle doesn't actually limit fuel flow. If the flow area subtraction of the needle jet hole diameter and the needle diameter is larger than the flow area of your main jet.... then the main jet is ALWAYS on full and always sucking the entire fuel load through the main jet the moment the throttle opens and vacuum pulls through it. I hope this helps clear it up and help you understand why the needle is so critical.

It's the GPIO port on a Raspberry Pi 4b. It's running through a voltage splitter to get the voltage in range for the Pi. From there I wrote custom software with Python to read the signal and filter the data and record it to a file. From there I use excel to do the air resistance and weight resistance calculations to estimate power/Tq. I skipped the rolling resistance calculation(don't have variables to put into a rolling resistance calc). The software portion was the hardest part for me since I'm a mechanical engineer, not electrical/computer.

@@flyonlynz It's been awhile since I wrote and looked through the program. To capture my data I wrote a loop that only runs when a switch is on. When the loops is running it writes time data to a memory array when input is detected from the RPM signal, otherwise it just loops. When the switch turns off it does a multitude of data processing to convert the recorded array events into RPM and a few other data points if I remember right, then it writes the array to a csv file. I remember in testing I ran the for loop with a simple array write function only, so every iteration of the loop it would write data to the array, just to see what sort of times it could produce in theory at maximum. I don't remember the exact time sequence that wire function took but it was faster than the highest RPM I could expect to see by a decent amount. In other words the collection frequency is faster than the max RPM. Noise reduction is a HUGE problem though. the Pi was almost unusable for data collection with how noisy the spark signal is from the CDI. The noise showed up on oscilloscope, not just recorded data.

My excel sheet is a mess. I haven't played with it in a long time and there are no comments or instructions. I recommend using Google Sheets or excel and constructing your own spreadsheet calculator then you will fully understand the process and understand what you are doing for your unique application. Remember you want roughly 2.3x to 2.4x as much fuel over the correctly sized gasoline components. You want that same to apply to the fuel flow that the needle provides as the slide opens and closes. The fuel it provides is variable depending on how far you open and close the slide. You probably want about 2.35x more taper. To make your own excel or google docs sheet you use the needle jet hole diameter and needle diameter to calculate the doughnut shaped area that the fuel travels through in between the needle jet hole and needle. Run this calc for the stock gasoline diameter and taper across it's entire range of motion, then compare that to the new methanol needle taper and new needle jet diameter across it's entire range of motion. You want the fuel areas to be as close to 2.3x to 2.4x bigger for the new methanol components. You have to calculate the flow area as the needle travels vertical in incremental step sizes. I think I used .1mm step sizes. So you calculate the area at throttle closed position and the fuel flow area at .1mm more throttle open than the closed position, and .2mm above closed position and on and on until you reach full wide open. In your sheet set the new methanol needles taper as a variable you can easily adjust and the new methanol needle jet hole diameter as a variable you can adjust. Adjust the two variables to reach roughly 2.3 to 2.4 times more fuel across all opening positions as best as you can. Here's the link to all the CDI manuals for the ignitech units. There is no manual for the ACCDIP. You have to use the DCCDIP manual. It's the same unit, and basically the same wiring, the only difference is the AC off the stator being used to power the unit rather than a DC rectifier off the AC stator powering the unit. Hope that helps. www.ignitech.cz/en/stahnout/manuals

@@flyboyfs Each install will be unique, you have to figure out how big to upsize everything for your unique application and your unique carb. Telling you my jet sizes and needle sizes is not going to be useful for your bike. Every fuel delivery component needs to have it's flow AREA increased by 2.3 to 2.4 times bigger. You have to calculate everything with AREA, not diameter. Area = pi*r^2.... So if your main jet is a 140 keihen it's a 1.4mm hole. So we divide 1.4 by to to get .7. Area = 3.1415*(.7*.7) = 1.539. We take that flow area provided by the main jet and multiply by 2.3 for methanol. Methanol main jet flow area = 1.539*2.3 = 3.5405. Since Area = pi*r^2 we have 3.5405 = 3.1415*r^2. So we do some algebra... 3.5405/3.1415=r^2... 1.127=r^2... So we use square root. 1.176^.5=r = 1.061. Now we have the radius of our new main jet for methanol. So we just double radius to get diameter. 1.061*2 = 2.1232... So that's a 212 Keihen main jet. Repeat the same process for every fuel delivery hole. Just like in my video I explain there's a bunch of small fuel delivery passages that also need to be upsized to allow the flow requested by the jets. So make sure the passageways are at least larger than the jet size you are asking for. If the jet is sized larger than the fuel delivery hole in the aluminum body of the carb then the aluminum hole will be the jet size and it doesn't matter what you do to the jets... unless you upsize the hole in cast aluminum carb body. Hope that helps.

Good question! Yes it would work very well assuming you can get the fuel multiplication factors right. Nitromethane is a very good option. I don't know off hand what the fuel requirements are or the expected power gains. I like Methanol because it's not too high on the fueling requirements. I've done 20 minute moto's on the relatively small fuel tanked supermini. Not sure if you could accomplish the same with nitromethane. Watch the old 2strokestuffing nitromethane videos if you want an idea of what it takes.
