  1. Great idea! @JKBoyd, can you connect with Darryl or Lance? They would have a list of all the 5th gen header purchasers to PM.
  2. I with you, put me down for one of each
  3. I checked with my engineer and passivation and polishing/wire brushing are not the same net effect with 304 stainless steel. 304 stainless steel is more than 50% iron, around 20% chromium and about 10% nickel. Passivation dissolves the iron on the surface leaving the chromium, nickel, and other trace elements on the surface. These metals left on the surface oxidize when air dried after the acid treatment and form the protective oxide layer that prevents the iron underneath from oxidizing (rust). Polishing/wire brushing exposes fresh top surface of metal; in 304 stainless steel this is more than 50% iron so when the oxides form it doesn't make a protective barrier because of all the iron on the surface. It was explained to me that is why we passivate the equipment in the food processing plants after polishing them. @Ducnut, your headers look awesome and I congratulate you on getting them to a show bike finish. 304 stainless has corrosion resistance but this resistance decreases as temperatures rise, which unfortunately exhaust pipes get hot. Also, 304 stainless will corrode when exposed to chlorides at higher temps. Most of us ride in nice weather so it may not be an issue at all. If I can offer some friendly feedback, keep them clean, dry, and away from road salt (sodium chloride) to keep them looking great and avoid potential corrosion at the welds... or passivate them before installing. Your bike, your call. Have fun and be safe!
  4. I'm familiar with passivation. I've worked in food manufacturing for decades and passivated plenty of stainless steel equipment. The reason I asked the question is it has been my experience with stainless steel storage tanks and other equipment we always passivated after polishing the tanks. I wasn't sure if polishing the headers after passivation could compromise or remove part of the oxide layer and leave the polished headers more susceptible to rust and corrosion.
  5. Does anyone know if polishing the headers effects the passivation?
  6. I'm with you, Man! I'll take one too... I think I'm going to need it in the near future
  7. Are these bung plugs short enough where they don't extend into the exhaust stream?
  8. Hey Seb, I hope you and your family are safe and well ! I’ll take one. Thanks Man!
  9. Look what BEAUTIFUL curves showed up at my house today! Box and contents arrived immaculate... thank you for taking such good care packing up my 5th gen goodies. I think these will become family heirlooms to be cherished by my descendants for generations! Lance and Darryl you guys ROCK!!!
  10. Thanks for checking. I might just swap in a 6th gen cushion and get rear sets and quick shifter in the process
  11. Hey Seb, I know it is for 6th gens but my 5th gen mid-pipe doesn’t have a stop. What does it mount to and could I use it on a 5th gen? Russ
  12. Yeah, with the active noise canceling I couldn’t hear the engine. I would have to look at the tach to see if it was running. I thumbed the starter button on a few different occasions thinking the engine was off. My ear buds did a great job canceling engine noise... too good a job in my opinion. I need that engine feedback when I’m carving twisties to know where I’m at in the power band. I wish they were able to cancel wind noise as well but they don’t. They aren’t able to produce all the out of phase frequencies to effectively cancel out wind noise. Now I wear my custom molded earplugs I got at TMAC and get the best of both worlds. I hear everything I want to hear but appropriately attenuated to protect what hearing I have left.
  13. I have used active noise canceling with Audio Technica ear buds. Very highly rated and well reviewed piece of kit. They worked well on planes... as matter of fact, I could hear the bench seats creaking as they were expose to increasing loads during take offs and I could hear peoples conversations two rows away. Unfortunately, canceling wind noise is a tricky business and and there is a background whoosh as the electronics try to compensate and cancel. You end up trading one noise for another. My hearing loss is substantial from loud radios, concerts, about 100k miles of riding without protection, and 23 years in manufacturing... I have significant “ringing” in my ears after riding with active noise canceling. Mine sound more like cicadas than crickets ( a simultaneous confluence of 13 & 17 year periods)! ... and you lose the glorious whine of a 5th gen engine singing its high notes!
  14. Thank you for all you & Duc2V4 have done!!! Most people will never realize the amount of work it took to bring this to fruition. The hours, days, weeks, months, years of effort... like having second job but not getting paid for it! You did what none of us were able to in the past... What you have done is amazing and our community can never thank you enough! I look forward to hearing from you on the 5th gen headers! With my sincere gratitude and respect, Russ
  15. Nice! Just in time for Christmas... ... makes me wish I had a 4th gen!
  16. FedEx emailed that my 8th gens should be here today... so excited!
  17. The front sprocket is interchangeable between 5th & 6th gens. IIRC, the 5th is a 17 teeth front and the 6th is 16 teeth, both bikes have same number of rear sprocket teeth (43t). Switching to the 6th gen front sprocket is common 5th gen mod to give better acceleration because of the gear ratio change. I advise replacing both front and rear sprockets when you install a new chain to get the best results and longest life from the chain.
  18. You are correct, sir... the Rapidbike can use the narrow band OEM sensors with a standard map or the upgrade Autotune with a wideband O2 sensor. Heh, heh, heh... Bung-holio!
  19. 5th gen motors and gear boxes are practically bullet proof. The PO might have changed the gears and not the chain. Go with a new set of chain and gears and you’ll be happy. They are maintenance items and they wear out...
  20. Go with a new chain and sprockets set... especially, if you don’t know how old the current ones are
  21. I’d be surprised if it is not your chain and sprockets. 6th gear low rpms accentuates the issue because of the power pulses from the syncopated firing order engine. That, plus tight and loose sections of chain can give weird sounds. If you hear hoof beats think horses not zebras (unless your in Africa!). How many km on your chain and sprockets?
  22. Some states put a prefix letter on the title ( A=1, B=2, etc.) to indicate how many times the vehicle has been titled. This may give you an idea on how many previous owners.
