going off your dyno sheet I see your point, 5-6000 rpm would seem like the weak area in the power output of your engine, You really cant afford to make that dip any bigger

Why would you assume or implie that what i write is a theory, Do you not think other people have tested. As i said I don't have a dog in the fight or i didn't, im just saying it how I see it from years of racing, porting and being successful at is as well I talk theories around beers with mates...

Yes I have a rough idea. Let me explain it to you When the exhaust port opens there is a set time before the transfer opens sends the incoming charge into the cylinder. The amount of pressure drop between the exhaust port opening and the transfers opening is called blow down and can be...

Do you actually warranty what you sell ?? But no I didn't read over it was early in the morning before the gym . But other than a few grammar mistakes please show me where I was wrong. Or are you just being a grammar nazi. If your coming here to just pick a fight your going to get the thread...

On another note the only cylinder here that could afford to run that lower port timing on the exhaust is the tpe. The other cylinder with a single exhaust port wold still have way to much pressure in the cylinder when the transfers opened and actually stall or even worse reverse the flow in the...

im not sure you really can. It's more of a saying than a science. I used to tune with a gauge that measured my g-force. After all that what I wanted up the start straight the max acceleration. The interesting thing I found was that the lowest pitch prop did not always give me the same...

The reality is if the cylinders shared the same port timing some one has screwed up. There is such a thing as blow down port time area and the tpe has way more of that There blowdown port time /area is way larger than the et. I have no dog in the fight but an educated eye can see that the tpe is...

stop making sense, the amount of people looking at the wrong end of their skis always makes me laugh. I remember when I was racing 650 limited in 1993 every race event they were looking at my engine trying to figure out what was up. The would have been way better off with a torch up the pump. A...

Don't worry mate. We want you to keep the doors open as well

16/23 in my slightly modified blaster it would fry it off the line. It had so much torque it scared me so im putting the engine into a superjet

Nice looking pipe Tim. what made you decide to go for a pressure formed pipe over a welded up system. Is it just an economic thing as in time taken

gold coast life. going over to an island for a holiday

Yeah Im hearing you on that one, Some times I go to post and go you know what fook it. Im just going to have to deal with the muppets who think they know because they read it some where

Can you put your finger in there please and measure the voltage on the ouch fook meter

This is what bad tuning on a dyno looks like, Surprised this engine didn't blow it would hardly pull on the lows, Actually at 3:48 is where it sounds like it blows and some one starts to say a rude word

yes that's what the delay is for, When I set up an ignition I normally just throw in a flat line say 15 degree and just rev it up and see how it reacts in regard to the timing moving. I find you get a fluctuation but its normally pretty stable. I have not used compensation ever before on a...

Dual curves as much as it sounds great is not that much use to you as it changes the fuel curve needed, You could run it with a low limiter on the same style curve like a hole shot button for racing. But even then its just going to foul the plugs, You could run it really retarded and make it...

Im a little confused as to what you are asking. In the picture that they have in the manual it says 35 degree and they say there unit is 40 degree is that what you are refering to ? What ever that value is is the most ignition timing you can run on an ignition. I didn't get any walk or not much...

The ignition needs to know how far in degrees it sees the lump so it know how long to hold the spark. I have not needed to run the delay compensation before it's never been an issue. X2 and I have spoken about this ignition backwards and forwards. It looks like it's going to be a good reliable...

Does anyone know of hand what the stock pump hub size. Im trying to work out areas of the pump versus another pump Thanks
