  1. 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
  2. Nice! Just in time for Christmas... ... makes me wish I had a 4th gen!
  3. FedEx emailed that my 8th gens should be here today... so excited!
  4. 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.
  5. 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!
  6. 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...
  7. Go with a new chain and sprockets set... especially, if you don’t know how old the current ones are
  8. 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?
  9. 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.
  10. Sorry, 5.5 gen and 6th gen have two stock O2 sensors... I think 8th gen has one. I apologize if I caused any confusion. The same explanation applies though.
  11. With this arrangement You can use a single Rapidbike wide band O2 sensor in conjunction with your 2 stock O2 sensors. The Rapidbike will send a constant message to your ECU that everything is cool with the fuel mixture and and you won’t get any error codes for missing O2 sensors while the wide band sensor will adjust the actual A/F ratio to whatever you target. This will keep you from throwing “Check Engine” error codes and entering “Limp Home” mode because the O2 sensors are actually reading a too rich condition (if you target 13.1 A/F ratio for optimum power). You are correct though, putting three 18mm bungs would have been more flexible because it would have allowed the use of two wide band O2 sensors for those who wanted too but you would have to have wired in resistors into the stock O2 sensors wiring harness to trick the ECU into thinking the stock sensors are still there. The current set up is the most user friendly and easiest to set up for the greatest number of people.
  12. Hi Guys, Any update or possible ETA on next available lot of headers? Do we need to obtain additional orders? Thanks!
  13. Hi Guys! I have read this whole thread and I don’t recall if it is stated... what type of stainless steel is used in the construction of the headers? Is it 304, 314, 409, 430, etc.? I was thinking of having them electropolished and the metal finisher needs to know which stainless steel alloy is used. Thanks!
  14. Great looking vintage bike! Welcome to the forum!
  15. Wow! Must be incredible living in an area with such natural beauty around the next bend! I’m jelly...
  16. No worries, do what works for you and I trust Jamie implicitly. Just for clarity, Jamie isn’t saying the 929 shock is dangerous to ride he is saying if he didn’t attend to all the details it would be dangerous... I just wanted to head that off before any swirl started 😎
  17. Jamie makes and installs an adapter for the top bolt on the 929 shock that makes it a direct swap out/in with the stock shock and adds a little rear ride height to improve handling.
  18. If your up for it, I would recommend buying a used CBR929 Showa rear shock and send that to Jamie for rebuild/respring. They are cheap on the auction sites and it will give you greater adjustability for compression and rebound dampening and it has an external reservoir to help keep the shock oil cooler and last longer than the original... I'm pretty sure he does it for the same $295 as your stock shock and you will get better performance 👍
  19. BR - it’s cool to come back after a year or so and see some things haven’t changed... it’s quite comforting actually. I’m glad to see your still around! I look forward to connecting and catching up on a ride someday
  20. I’m glad to be back. I can’t wait get back and ride the Smokies again... eastern TN is where I wanted to move to for the riding but the wife wanted Florida. ... so we moved to Florida lol i look forward to getting back and connecting! I’ll definitely look you up when I’m in the area! Im actually a couple of hundred miles closer with my new address than I was riding from STL
  21. I’m glad the fork tube adjustment is working well for you... it really improves Handling on most of our bikes...
  22. All of my bikes are V4s too... I’m digging the groovy classic variety though! if I had the room I’d include a similar Beemer and many other examples of two wheeled Nirvana!
  23. You can change my order to two (2) 5th/6th headers if that helps move the needle closer to production. I’ll buy an 8th gen for front rads at a later date. Let me know where/when/how to place deposit or pay in full.
  24. I have 98-99 headers with the welds ground flush on my bike. Losing the cat makes a very noticeable difference in sound, weight, and top end pull. We are trying to get another batch of performance headers made so if you are interested we need the numbers.... and they are better than 98-99 and they are stainless
