    That'll do.

     

    Was the bike just positioned incorrectly on the roller?

     

    Ciao,

    Yes. My wheelbase must be a bit shorter than Mike's due to chain and sprocket differences. It was an unfortunate oversight. The shop owner has told me to bring the bike back to run again another day. I'm going to hunt down some good fuel or maybe even proper racing fuel and have another go in the coming weeks.

  2. ***Dyno numbers are in***

     

    Michael Dixon me this morning to run both of our bikes back to back. He has a slip on, but otherwise stock. He went first and his 07 Anniversary pulled 96.06hp.

     

    Mine went up next and pulled 152.86hp!

    Unfortunately, this was with the tire rubbing on the table(see video), but that just means there's still meat on the bone. I guess I'll have to find some race fuel and go back for another run!

     

    Roughly 60% or almost 60hp gain is not bad for a little old VFR800 🙂

     

    We did very basic runs, hp only, we didn't connect to the ignition to pick up torque and rpm numbers.

     

    I had 91 ethanol-free with a splash of octane booster in the tank. Not sure what fuel Mike had.

     

    This all goes to show just how important doing a baseline run is. This same exact unit pulled 202hp on another dyno on the previous owner's bike, but no baseline had been done. I am using the dyno map from that run in my bike.

    This is 3 of my pulls on top of one of Mike's:

    Since I've got one A&A supercharger kit and two 5th gens, I have often thought about making my own.  It wouldn't be rocket science to reverse-engineer what A&A did and assemble a new kit of parts doing pretty much the same thing, but neither would it be "cheap".  Ethically, once he abandoned the market, he can't really blame people for thinking about resorting to "self-help". 

     

    Unfortunately, I didn't measure anything before I installed mine, so I'd have to remove it from the bike to do that.  If only someone with mad engineering and fabrication skills had had such a kit in his hands for an extended period of time before installing it... :tongue:

     

    Ciao,

    The thought crossed my mind.

     

    A new 5th gen kit would have the same issues I worked through on mine re: oil reservoir location and re-plumbing the Rotrex oil supply with an oil cooler.

    This is a work of art and you have a gift to be able to do something like this.  My mind is blown.  Totally amazing work.  Congratulations.

     

    Thank you! 

     

    I've been enjoying putting a few miles on it, now that the weather is nice again.

    We did converse through your build and I could see that you were undertaking a very complex project but when I finally read this thread… Wow, I mean, wow, my mind is blown!

     

    I had to go back and read the posts several times to even start to comprehend what you did to the stock kit. Excellent work, great craftmanship, beautiful bike….

     

    At least I can claim to have contributed to your success. I did buy the kit in the first place 🤪

     

    You were very helpful along the way - the dyno maps were a godsend, thank you

    Any thought that this could be done for the 5G, adapting the 8G cover? It looks like the 6/8G cover may have an extra dowl?

     

    I want to say yes, but I'm not sure about details of fitting. I have a 99 and another 2014 cover here, but the bike isn't in a good position for me to pull the cover and check.

    Wow, amazing skills and attention to detail! Awesome how you fit everything in there, and made it all functional to the highest order. 

     

    Any dyno numbers, or a weight, for us "numbers geeks" out there... 😀

     

    Thank you!

     

    I wish I could report some numbers... I tried to get in at Wheeler's during my trip south, but his dynos were both down. I don't have any local to me, and the nearest want way too much for a simple power pull. I was hooing to get a tandem run with a stock VFR800 and mine on the same day/same machine for a true comparison. 

     

    I do have a great lead on getting an accurate weight - I have an in with a local scrapper who will let me roll it up on a scale. I didn't get to it last year, but later this spring I will.

    As you may recall from my build, a VTR fan blade will reverse airflow and blow outward through your left radiator. It appears to be a more efficient design, as well. 
     

    Also, my suspension was done by Traxxion with slightly more front spring rate and the same rear. Internet experts have claimed the rates are too stiff. Riding it proves otherwise. Like yours, it’s amazing. 

     

     

     

    That fan absolutely crossed my mind as I was pondering all the mods. In the end, I decided against it for a few simple reasons.

     

    1. I'm using the oem fan location as an auxiliary, so top efficiency is less important. 

    2. In stopped or slow traffic, it makes more sense to draw outside air in, and that's when I'll be using that fan. 

    3. Cost of adding another part

    4. Internet evidence suggested a small chance of catching debris between the fan blade and my (now very custom) radiator made me most hesitant. No room left to add a debris shield. 

     

    Thankfully, the choice worked out. It was in the mid to high 80s and pushing 90f during the spring ride & very humid too. I had zero overheating issues. I did see some higher temps, but nothing I hadn't seen with the stock VFR.

    Oopsie indeed. Did he u-turn and discuss your acceleration performance? Had a similar fly-by in the Adirondacks a number of years ago, same blue with orange stripe, but he kept going.

     

    Keep posting those beautiful bikes!

     

    I was expecting that, but no he never turned around. I quit while I was ahead, turned around and parked it.

  10. One of my Dragon runs with my buddy Travis chasing on his GasGas supermoto. Unfortunately the camera cut off toward the end, just as things were getting spicy. 

     

    Watch in hi def and you can see the rubber stripes being painted on the corner exits 😎
