2006 Honda 919 Project, phase one. Notes pictures and bad drawings...

All,

Attached is a document that I built while doing a little project on my 919 this winter. I have done several projects years back but never really took the time to document the work. Parts and pieces of the project were posted on a thread started by ahung called “winter build”. I mentioned on there that I would post my entire document when the project was complete. I thought this would give each step of it some continuity. In any case, this is how it turned out...

So it was mainly just switching the cams to the 900RR cams and working the head, and removing the cat. You got a 14% improvement from that... unreal.

Amazing job.

The welding of the cam is one thing that would scare most away. Glad someone actually did a dyno on this because most mods never get past "if feels faster".

I hope that Google Drive doesn't end up the same as those picture hosts we've had before where after a few years, it's a dead link.

Thanks KarlJay,

If I had to estimate the hierarchy of what made the difference in terms of net gains, I would say: 1 the cylinder head, 2 the fuel injection or TB's, 3 the cams, and 4 the exhaust. That would be my estimate based on visual assessment and specifications, but again, this would just be my estimate. In the old days I would make changes one at a time to really determine individual component values. Some things are more important than others and some add no value to a given configuration. In my old age, I am looking forward to riding more than working once the weather breaks. So I just drew from past experiences and touched what I thought needed help. In any case on initial disassembly, I was very optimistic about the potential of this little motor as it pertains to making a few extra ponies without selling the farm. Great bikes for such tinkering or anything else one wants to do.

The upside is that these bike aren't very expensive compared to some others. You can pick up a good one for < 3K.

I did that kinda work on my 700S, it was about an 6~700 investment. Alum heads aren't so hard to port after you've done iron

Did you make the velocity stacks?

With the 700S the carb jet kit and K&N combo make a good difference.

I haven't gotten to the point where I'm at the edge of the 919's stock power. I was on the 700 canyon carving and after a while I was getting to it's limit on power, but I haven't done that with the 919 (yet).

No, the bike has velocity stacks already on it that are in the air box.

I'm hoping you and I can get together sometime this season, Mark. You can ride my 990 Super Duke, and maybe you'll allow me to try your "919RR".

Where did you Dyno your bike?

Sure Snyder-X, we will definitely get together this summer and you are more than welcome to ride the 919. I had my bike dunked at Commonwelth, the same place as you.

My bad... I should have looked at your Dyno sheet closer. This is mine after the Rottweiler intake, before and after being tuned. My point being if you got a 919 to equal a KTM 990, that is quite an achievement. In my book.

Very impressive Snyper-X. I an sure that is a great ride, especially with all the instant torque! Do you have a picture of your bike?

Mark, what a small world. John and I have known each other for years, worked together, and rode together. Same goes for Bernie. I live right down the road from John. Nice work on the 9'er.
