A few more of those little horses jammed into the motor today. After an intake mod and a plug heat range change. Every little bit helps. Good for 35.17 hp and 36.55 ft lbs. consistently on the Dyno ....
Because it's winter , and I'm a little bored
See if we can stuff a couple more of those little horses in there ... Maybe ? I have been thinking about the placement of the Injector, in particular it's distance from the Intake valve. I "THINK" it is rather close to the intake valve... at least for performance. And I think from what we have seen here, that fuel puddles a little too much in the intake port. Not so much on mine, but the stock bikes seem to do it. I also think that a little more distance from the back of the valve will give the fuel spray from the injector a little more time spent in the intake port to atomize. Hopefully.... gaining a little more efficiency from it, and in turn a wee bit more power. I know from tuning on the bike, with the intake modification in the manifold placed behind the injector helps. It atomizes the fuel better and is good for 1-4 hp, depending on the configuration. Can't do much with the with the stock intake manifold, the injector location and it's angle ? Also... I know the stock insulator between the intake port and manifold is crap. At least for my needs. It deteriorates and gets blown apart on the inside, around the intake port.
So , with that in mind I figured I would play around and see if I could kill two birds with one stone..... Sorry Wildbill.
From some scrap Phenolic material, a new insulator was made at a little over double the width of the stock insulator. Moving the injector back a wee bit, and hopefully the material will prove better then the stock insulator. Witchcraft ? .... Maybe
But what the hell, lets see ? I'm bored ! LOL !......
