Trickster!! Was that cool bit of billet a special gift with the pipe or did you just fab it up in your spare time? Looks very good and the pipe tucks in well. I guess it's cam install time and then off to the dyno for you.

carbon fiber and Kevlar cloths
Hi Jimmy,

You didn't ask, but I'll share what little experience I have making stuff with the Kevlar cloth. It is really hard to cut with shears, unless you have the special micro-serrated type. I only used Kevlar cloth where puncture and abrasion were factors. You might have an all-around easier time with just carbon. But I love how the carbon/kevlar weave looks.

like a snail, the slow snail trailing in the back :-\. I found out I have a son last September so that's been takin up a bit of time and money. Don't get me wrong I love him but... ;D. On top of that ran into some problems with my 500 (super loud valve chatter, and possible tranny/primary issues). So I'm gonna pour what I can into the 500 to get it ready for the relay

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

I expected it to be different too Kemp.

I deleted the photos of the bike with the MotoGP Yoshi replica pipe cause I really don’t want to promote products like that on my build thread. These MotoGP pipes have been a Royal PITA.

I've had two different ones to date and they where both plagued with fitment and build quality issues.

I’m gonna stick with the tried and true Kerker megaphone exhaust that you see in the pictures from now on.

I actually have two Kerker megaphones. One chrome and the other flat black, and I’m thinking the black meg might look a bit more menacing than the chrome. I’ll snap some pics and post them tonight for your comments.

Cheers

Hi Jimmy, not trying to be a pain in the arse mate but why keep dredging up the moto gp pipes problems you had.? That quote was from February and i think you should be over it by now, remember that you weren't the only one to get his pipes and mine are excellent and i will buy more. We all know that you had problems mate, might be time to let it go..... ;)

Like i said Jim, i don't want any drama mate but dredging up 4 month old posts just to have a #$%* is grabbing at straws. Yes i have had my pipes on and there was no fitment issues, {i have an engine in frame for mock ups} i expected there to be none as he has made hundreds of my style of pipe {750} for Carpy and others. You had a bad experience, i get that, but one bad experience does not make a bad seller mate, it may for you but to put it in the bad sellers section would not be correct as that section is there to warn buyers of bad sellers, Chris, in my and many others opinions and experience { he went to great pains to make my pipes so that they could be shipped to Aus cheaper and then charged me NO SHIPPING}, is not a bad seller, i am sorry you had a bad experience Jim but one bad experience does not make a bad seller, sometimes #$%* happens.....Time to move on..... ;)

Well it looks like I’m down to the last couple of decisions before spending the summer racking up the miles. That is if summer ever arrives on the wet coast.

I have a black Kerker megaphone and a chrome one and I think I have already made up my mind which one I like better, but I’d like your opinion too.







The chemicals are nasty, that's why you almost can't do it in the USA anymore. We now have to ship the plumbing and door hardware items I deal with to Mexico now.

I'm not big on shinny but on that bike I would go with the chrome Kerker.

I just read your whole thread again. I think you have inspired me to buy a lathe and a mill and teach myself how to use them. I used a lathe once or twice in woodshop in the eight grade. Haha!

I haven’t purchased a mill yet, but the lathe has been invaluable and great for my mental health. You can pickup some good machines from Grizzly Industrial (http://www.grizzley.com) in Bellingham WA.

Good fun with great friends.




This picture should be in the "INSPIRATION GALLERY". Great looking bikes, and a great tread:)

I just do not see the improvement with the yamaha front forks.
You still have telescopic front forks and single disk brake.

I bought that exact bike the first week it was introduced and was racing dirt track motorcycles (not the 400F-4), at that time and I rode my 400F hard on the street and it handled very well with the stock front forks.

Question...Why do you keep giving measurements in mm's?
Are you from france?

"As an example, a bike with a front tire having a circumference of 1890mm."
That would be 74.4 inches circumference.
Makes no sense. Diameter is what is needed

" a 23-degree rake and 27mm of offset will have 98.5mm of trail. Note that in the range of variables we are dealing with"

That is 3.87 inches of trail. = 98.5mm
But why throw in the offset? The offset of the bottom and top triple tree are the same.
With less offset the rider just has less leverage over the steering .

I just do not see the improvement.
Matter of fact these modern sportbikes have such steep rake that they all have to have steering dampners now. That is NOT an improvement as far as I am concerned.
Some Suzuki's now only have 24º of rake!! Crazy.

The stock bike  CB400F
rake/trail/and wheelbase
numbers that were not seen
before or after: 26.5 degree rake,
3.346 inches trail, and a short 53.5”
wheelbase.

26.5º was seen as very steep rake at that time.
The most successful racing motorcycle ever designed had about 29º-30ºrake.
It was the XR750 H-D.

Matter of fact in the last 6 months almost all references to the measurements of the XR750 frame have been removed from the internet due tho the fact some people started to copy that frame design.

This is not directed at lucky, because IMO he's a troll.  But just in case someone else new to motorcycling is reading this wants to learn something:

There's a huge difference between damping rod forks and a proper modern cartridge fork, and a similar difference between a 40 year old single-piston 2-piece caliper and a modern 4-piston monobloc caliper.  Lastly, the larger semi-floating brake disc works better than the stocker.

I live in TN and the metric system is ten times better to use than US system.  You know how much of  pain in the butt it is to do conversions using US standard?  I used to always convert to metric on my exams then convert back to Standard if that's what the professor wanted.  A hogshead, a furlong?  Seriously?
