Ahhh. Makes sense. Thanks for the info!

We were also discussing having the mill table ground square. (Blanchard ground) Thoughts on that?

You adjust the head to be square with the table; the head is adjustable, while the table is the constant, unless there is severe damage or wear to the table surface. Minor boo-boos, or tattoos can be "stoned" off with a common flat 3x5" sharpening stone, like your grandfather used to sharpen his fishing knife. The idea of stoning is to only remove the very slight ridges left at the edges of the tattoos, but not the rest of the table surface; you can feel the drag of the stone over the ridges.

Wow, what a great addition to the shop!

Is $1100 a mega-bargain, or should I start planning to get one of these too once I have a shop again?

FWIW, I'm not a shill for Race Tech - I've just got a thing for good suspension and the RTCE's are the most cost-effective mod for these old damping rod front ends.

I honestly don't know. Someone who knows better please chime in. It was a bargain to me because we went halfs on them.    8)

Looks good erick.  I did some test fitting and have some issues to work out in regards to cooling flow.  ???

I will hit you up tomorrow and see what you think.

Without digging back through, what do you guys have to do to qualify as a rider there? I just read an article in American Motorcyclist about running 175mph to qualify the rider?? Maybe I missed something.

That is for SCTA riders that have entered a bike in a class with that speed -record or higher. Those runs are made on the long course.  All others are on the short-course.  If you want FIM sanctioning, you also have to submit a recent physical with your application.  I think I understand that SCTA also requires a rookie-run but has just recently allowed that the run may also qualify for a record attempt on the short-course. The BUB event has very similar AMA rules and also has FIM sanctioning...........I am not aware of a rookie-run requirement.

I think its a very good idea to take a cruise on the salt to familiarize yourself with the course markers and how to exit and return to the pits.

At BUB they do a rookie orientation where you can drive your car or bike down the salt to see everything it is very helpful.

Anyone have experience with steering dampners?  Any reason to spend big bucks on an aftermarket, or will a used factory one be sufficient?

Monday they are there for a reason, its your backside  so  spend accordingly  ;).... bit like a helmet decision I guess

I posted a pic of the latest Honda dirt bike CR 450 or something, very small and mounted vertically on the front of the head stock....... light , not sticking out into the wind on one side,    new about $400.

Has anybody gotten one that they didn't like, and if so, what didn't they like about it?

How about one that they liked well, or upgraded to?  What made it better?

Are there better/worse brands, not just higher/lower price?  Do they fail? 

Is there something that would make them not pass tech?

Looking for some experience and specifics.

Gday mate, i always use them on my 750/4's, actually, nearly every bike i ve ever owned either had one or i fitted one. On the Old Honda's i just use the old Kawasaki style NHL dampers, cheap enough and make a noticeable difference to stability, if you set the to the higher settings you will notice and induced weave at slow speeds as the front end is tighter and harder to steer, great at high speed though, also i fitted them after experiencing some scary tank slappers, never had a slapper with a damper fitted.  I use the 3rd setting on them for the street, they can be adjusted on the fly...

Ignore the price. they can be found cheaper... ;)

I have one from a '00 GSXR lying around my garage someplace. Let me know if it'll work and I'll try to find it.

The critical aspect of the "bargain" dampener is the effective movement at the center-point........ie.....no play and equal restriction in both directions.  I have seen several 'cross' mounts going from the fork-tube or outer portion of the lower tree and then to the opposite side of the frame down-tube to avoid hitting the head on a wide motor.

Going back to your intake design.....others have commented and I agree....a prolonged lean condition on any piston can lead to a grenade condition......Its a long way at WFO between the timing lights.....The Lake Gardener reports confirm.

Well that's gospel for LSR. Anything using nitrous (the worst IMO) or forced induction will blow through the edge of the piston and your seal is gone. The best case scenario is you lose power and cut the run or you really hurt the engine. I never got into turbo stuff though I enjoy the concept. Guys I know tell me to "boost" my busa but I like NA and always have.

I definitely don't want any lean cylinders.  A lot of effort was put into trying to design the manifold to flow as equally as possible..... lets hope it all works the way I hope  ;D


A very awesome benefit of running this fuel injection is the ability to control individual injectors.  This year we will have to do some plug reading to dial in each cylinder, but there is discussion of running 4 widebands in the future.

Never had that as a problem on a 750 so it should be an easy fit on the 350.... ;)

Erick (EBCB) gave me a call last week and wanted to contribute more to the project.  Cant say no to that!  It amazes me how eager people are to help out others.  Learning a lot of life lesson on this project.  He just made one to test fitment with.  We made it nice and solid to retain strength, but Im worried it will block too much airflow to the head. 









Next up was more work on tank template fabrication.  Another new friend Jay Basler stopped by to lend a hand getting some measurments for the top of the tank.  Big thanks to him..... It gets pretty awkward trying to sit in full tuck position with one arm holding a ruler while blind measuring!  :o











I reached a point with the tank that it was time to start making final decision on where to mount the battery and intercooler, which made for the most logical routing of the hot and cold intercooler pipes.  First up is the battery. Thanks to my dad and friend Chris Kellar for coming out Thursday.  Dad provided moral support while Chris put some time in on the camera.
















I decided the idle air control valve had to go.






The week ended on mixed emotions.  Saturday morning at 5am I received a call from my brother informing me of the passing of our grand father.  He has been battling cancer for many years, but since his wifes (our grandmother) passing about a year in a half ago things started to go down hill.  He has been in a lot of pain lately and it has been extremely hard to see him in this shape.  He was a greatly compassionate, patient, humble, loving, humorous man.  Only now do I realize what a noble life he led.  Im not sad, but proud to have had him in my life.  I hope people see my life the way I see his when Im gone.
