Not the best worded statement you ever wrote Jimmy.....

Well, with your design and fab skills you've earned the right to get a few words wrong here and there.

Oops. Blame it on lack of coffee or perhaps alcohol withdrawl.
What I REALLY meant to say was “all you’ll get is a glimpse of my a$$ as I blow past you sucker!

Better Mick? 

Yep   
Although i still don't like ass, sucker and blowing in the same sentence....

No I haven’t tried different offset setting because the spot that I have it at now already increases trail over stock and the other setting just increase it more.
Don’t need anymore trail than what I have.

Yea, this is gonna be an even bigger problem on the 400 since the stock offset is 60mm. I'm gonna gain too much trail. Well, I have a line on the front-end, and once I get the wheel/brakes sorted, I'll machine new triples if I don't like the steering.

Jeez, I better start my own project thread

Not to hijack, but if people want to see me try the R6 front-end on a CB400F, look over here.

Thanks for the inspiration Jimmy. I picked up the front-end today.

[Retro Rocket]

There probably are, but the guy I use (beer for anodizing) mainly does silver and black, the basics.
I think he also has gold, green, red, orange and purple, but those don’t run as often. 

Thanks mate, you have to love the Beer Economy.....

Well that was then, you can call yours a modern, Bada$$ bike! enjoyed reading the whole thread and will probably refer to it several times during my build, which is not to impressive right now as it is all in peices but it will start coming together soon!

[brettster26]

if your putting those on there, PM me if you want to sell the ones you have on there they look like they are in much better shape then the ones that came on my bike...

those will look pretty cool!

Actually the intake tract is approx. 20mm shorter than the stock intake tract using this setup, and I think that moves the power up the RPM range slightly.

Correct.

Nice work!!!

]Is there a formula to work inlet tract length out or is it trial and error.? I am building a big engine and want more torque or power in the lower rev range,,

You could probably get a decent approximation with just a simple function of intake tract length, target peak RPM, and the speed of sound.  But here's a calculator.

Thanks for the link but when using small amounts {2-3 inches} it replies with rev ranges in the 10's of thousands...?

Sounds about right.  Look at how long the runners are on a tunnel-ram intake that's tuned to ~5,000 RPM, or the old Dodge cross-ram intakes that were tuned to ~2500 RPM.

Better tighten up the bottom end then. 

Thats an understatement ....   some readings for a 2 inch intake were at 30,000 rpm, so its useless trying to work inlet tract length using that converter.....unless i am totally missing something..?

Mick

[syth82]

2 inches is pretty short. You need to figure intake valve to the end of the throat of your stacks.

[syth82]

Also that calculator is a little too simple. cross section, at least throat diameter, should be taken into account also. I have formulas for all of this somewhere... In a box in 300 miles away, most likely.

Yeah i know , i just posted that as an example....

That Brembo is a 13mm and with the single R6 caliper I find it a bit firm for my liking. I prefer a more progressive (softer) feel at the lever, so I’ve ordered an 11mm Brembo that should be here soon.

Jimmy, did you ever get that 11mm master? Which do you prefer? My goal is to use a used OE part from another bike.

Thanks,
Dave

Looks amazing. Wonder if you could make another set? I have a set of Mikuni Smoothbores adapted to a modified honda 4 rack.

[Syscrush]

Just when you think you’ve got it all sorted out, you find another obstacle.
What to do when your fuel petcock is in constant contact with the carb?

Replace it with a vacuum-operated petcock like on an SV650.

[Syscrush]

Before I send it out for a full polish I wanted to get some feedback from you.
What do you think?

I think it just moved. 

Wow.  What's in there for baffling?  How loud is it?

[Greggo]

The pipe looks fantastic there Jimmy.  I'd love to hear it!!!

[Kemp]

I like it, interesting look but not quite what I expected looking at the prototype on Motogpwerks. Maybe it's the angle of the photo. I expected the mid-section/tail pipe to curl under the middle of the engine and then finish with an "S" section curving out and then back in and up

[ivanhoew]

just a beautifull thing . only personal changes would be off with the wing mirrors and on with one mirror on the offside coming from the switch gear , like the trad honda ones ,and a longer silencer out to the wheel rim .but purely nit picking ,im in north vancouver for a month in may, i'll can look out for this now ,as well as the scenery .dont know which looks better !
