Dear sweet baby jeezuz!

So I went ahead and did all my mods at once.

Micron header (Thanks Big Dave)
Graves velocity stacks
BMC filter
Vcycle nut flash
AIS block off plates
NGK Iridium plugs

I just had a slip on before this but that was all. (Not de-catted)

Took it for it's maiden voyage today. It is quite a bit faster. From 7,000 RPM up it pulls harder. I am a skinny fella and it seems that no matter how far forward I get on the bike the front end comes up in first gear. (Stock sprockets) It is amazing! Oh, and the sound......it is definitely louder. But good God it sounds like Godzilla getting it on with Mrs. Godzilla and that special moment lasts as long as I hold open the throttle. (that is a good thing) The biggest difference is at idle, much deeper tone and sounds WAY better.

Here is a pic header (dirty ass bike). I have no idea how much HP I picked up but I figure I would be just like the other fellas that got between 150-155 at the wheel. I will dyno it later this spring.

Nothing new in this post but thanks to all of you who have done DIY write ups for everything from Lars airbox mod to Crazy Biker's AIS thread.

I thought I would post it as the forum has been slow.

Nice work, these bikes are a doddle to mod up.

Just FYI, they don't make 150HP at the wheel on an honest dyno. 135-140 with stock piston and cams. At least it sniffed for AF ratio before calling it done.

Several people have achieved 150hp, including Ivan who showed the dyno results.

Another good (and cheap) mod is putting the R6 throttle tube on. I don't remember the numbers but it takes a lot less rotation to reach full throttle.

Nice work. Whether it's 140 or 150, it's a nice strong pull in the fun zone. Nothing quite like that.

Now go put some miles on it

IIRC.......not quite a 1/4 but close to it. It will get you in the happy spot right quick. One other mod well worthwhile is 1 tooth down on front sprocket. Others have played with different ratios front and rear, maybe search those threads as well. Just a thought.

Thanks fellas. It is plenty of power regardless. For cars i know dynojet always had higher numbers than mustang dynos. I guess it just depends.

I will get it done and post up #s later this spring.

Nice! And per Vcyclenut dyno runs I think the most he has gotten with those mods and his tune is 146. Ivan gets 150ish with same mods.

It will also depend on the weather on the day, hot or cold and humidity. As long as the graph has a nice steady pull through the rev range you'll be happy! don't get too hung up on HP numbers.

For sure Dicko. It is plenty fast for me. I tried to dyno it last last Saturday but the dyno guy went home early. I think we are in for rain this coming Saturday...

Put a -1 front sprocket in there too.
Fully modded these things are a fricken rocket ship!

I am a skinny fella, first gear the front in comes up on it's own. I thought about a -1 but it is fast enough for me........for now
