Chilly New England spring day here, and I finally got my bike to the dyno for tuning.  60 miles to Gardner MA started at 48F and ended up dropping to 45 on the temp gauge.  No matter, this was my slot and Rob's Dyno is booking out to mid-June now... I've had the headers and PCV on for a few weeks now and took a few shakedown rides with it to make sure there were no issues...  

-Stop at Cumbies to warm up.

-Ready to rock!

Here's the particulars:

• 2000 VFR800, 38k miles on the odo.
• Headers (of course!)
• Two Brothers Racing carbon C-series slip-on
• PAIR Valve and snorkel mods
• BMC air filter
• O2 sensors jumped out with 300 ohm resistors
• Power Commander V

Happy to report Rob was able to tune my 2000 with no issue on the Power Commander V!

The base map's AFR was in the toilet.  He was able to clean that up, and ended up very happy with the results!

It ended up being a wet, cold ride home instead of just cold... so I didn't get to enjoy the ride home too much, but the throttle response and fueling is amazing now.  Thanks for putting this group buy together, and if you're thinking about pulling the trigger, don't wait!

Cheers,

Sean

Ok, let me dig through this thread and see who I need to contact for a deposit.  Unless that person wants to contact me first 🙃

Send a note to @sfdownhill and @Duc2V4.  they can get you sorted.

Since this thread has become the all-things-custom-headers-thread I'm posting here.......

 

I was in on the first batch of custom headers and after install it was immediately clear that the bike would benefit from a dyno tune. Surge at small, constant throttle openings, a general lack of crisp response to inputs, etc. This wasn't a surprise, I was actually pleased - the motor needing more fuel because its moving more air is a good thing

 

 

Who did the tuning for you?  Rob's Dyno??  I'd like to have a chat and figure out a game plan for my 5th Gen.

Thank you and appreciate the update.

I was more worried that, given the state of things, that with COVID and whatever else there was a bigger issue.  Relieved to hear there is not!!

When you have a moment, a solid number on how many are left for the new minimum order would be great.

Thanks again

Just to give an update. We currently have a new list going and are at the minimum number we need, just waiting on confirmation of the deposits. Most likely we will be there to move forward within the next week or so. If you are thinking about getting a set, now would be the time to chime in. Send me (Duc2V4) and sfdownhill a PM and we can get you sorted out.

I thought I'd add pricing here just to make it easy.

 

Headers: $830.00

Passivation: $90.00

Gaskets: $20.00 (set of 4)

PC Map: $50.00

Shipping: TBD (Based on your location) Prices range from $50-$90 within the lower 48.

 

Any update here?  Been a little over 10 weeks since we had the minimum for another run.

Just checking in here...  We ready to go on the latest set??

THANKS!!  Can't wait to get these on my bike.

I just finished the final install of the header, it's midnight here in Denver but I went ahead and rolled the bike outdoors to run it.  The install is a success, no leaks, sounds great.  I let the bike idle up to about 170 degrees on the temp gauge then shut it down and pushed it back into its parking spot in my garage.

 

In the end I decided to use the 41mm copper gaskets from Delkevic.  They are just a little less than twice as fat as the 42mm copper gaskets that Delkevic sells.  Because they are fatter I knew that during the installation "crush" they would probably end up spreading inward to about the same inner diameter as the original Honda OEM gaskets.

 

I didn't like how much the OEM gasket protruded into the exhaust flow and wanted my install to be better than that, so I decided to experiment a little.

 

I purchased 8 of the 41mm copper gaskets directly from Delkevic at their location in Littleton, CO.  Got to meet and chat with Matt (at Delkevic), he was very friendly and helpful.  I modified the 41mm gaskets by "pre-pinching" them inward, only by a little bit around the outside perimeter and then by as much as possible around the inner perimeter.  I did this so that when the crush of the install occurred the gasket would have a smaller starting point from which to spread.

 

The results were pretty good.  I practiced installing a couple of my "pre-pinched" 41mm copper gaskets on the front cylinders and after the crush they ended up with an inner diameter that was noticeably wider than the original Honda gaskets (although they do protrude slightly above the inner edges of the exhaust ports).

 

So I'm satisfied, the modified 41mm gaskets provide a very good, generous footing for the end of the header to bed into and their inner diameter is better (wider) than the OEM gaskets. 

 

Good enough for me.  On to other maintenance items...

Go back to page 19.

Honda Service Manual does not mention anything about seam.  IMHO this guy is making a big deal about nothing.  Again... the exhaust gasket, if properly installed, should be squished between the exhaust header and head opening.  There should not be any part that is in the flow of the exhaust gasses.

seem facing out from engine.

 

If you have it the other way, when crushed the seem will/may be catching the gases if it is outside of the internal wall of header.

This has been discussed.  If installed correctly, it should not interfere with the exhaust gas flow at all.

F it.  Quarantine brain and reading through all of this has finally broke me down.  Deposit sent.  Sorry Scottie, I can't steal your set... you need to hold onto them.
