If you go that small on your main that your going to seize your engine. You will be so low on power before it happens. There seems to be this rule of thinking that engines make the most power just before they lean seize. Not true at all. They start to make power as you go down in the jet size...

How is reverse jetting going to equal more blown up engines in the carnage thread ? What 50mm carbs did it have. What ignition system did it have in it with what curve. Just because it didn't run it doesn't mean it couldn't have run. I'm not here to say what you did was wrong. I'm here to speak...

Fair enough. I'm interested in fuel burn in my car not in my ski. How good do they sound with loads of fuel and lots of timing. Like a drag car and they hit like it as well i can understand that if your going for miles that the extra fuel may be an issue. I haven't found it to be excessive but...

I will add more when I get a proper kb in front of me

:woot:

Please if you don't understand don't decide that it can't work but ask away. now I talked about depression across the main jet. When you speed up the air flow you get a low pressure this is what makes your planes fly. When you do it in a carb throat you decrease the air pressure in relation to...

Ok it seems that the mb in my laptop is cactus and so going to be a while. So here we go please excuse my more mistakes than normal. As you know your carbs have a butterfly in that controls air movement. Well when you crack these open the air starts to move and for that brief second that the...

I will explain it when I get on my laptop I'm writing on an iPad and I hate that. There is a very good reason why it works so well

Looking forward to seeing it in action. I would love to get my hands on one of these cylinders and have a play with it

please post the curves you are running

It would go hard but twins would go better

I have used reverse jetting on every set of carbs I have tuned for the last 10 years except full spectrums. I have tried to tune some full spectrums about 8-9 years ago and found them very finicky to set up. This is not the right place to discuss this. Im more than happy to discuss my findings...

I love reverse jetting for a surf boat it works awesomely and will always be clean you just have to take the time to get the top jet set right. If its dont right you can cruise around for hours in the surf and have it hit right. Conventional jetting just doesnt make the torque that reverse does...

Of course if you are starting with an engine designed to make bigger power from the start then your going to get better results that stands to reason. as long as you have the 118 centres its always going to be a compromise. However this is the best design I have seen to work with this...

Ah yes most likely

Lol leg dragger you seem to read alot of the same forums I do

What a cool setup. msd total loss on it and away you would go. use a set of 785 polaris pipes. How much fun would it be

I heard your brother was a homo. Has he come out

That would be so dependent on who builds the engine the porting spec squish etc etc. Kinda hard to answer that question I would be expecting

I am But thats just an outsider looking in
