I went to the Thunderbeach Rally in Panama City this weekend. Estimated that there were 50k bikes in town for it. Rode my M2 over there. Yamaha had a demo trailer setup. I went for a test ride on a new Vmax with stated HP of 190 (160 @ tire I think). They actually let you ride it and not in a parking lot. This was scary fast, but made me appreciate my Buell even more. But, with only 90hp, I feel lacking now. What is the highest hp that anyone has achieved and still have great daily driving abilities? This is just a knowledge hunt... Thx Cory | ||

about 100~125 RWHP Highest HP Pammys late X1 160 RWHP, the bike was said to be largely experimental. | ||

NRHS has an m2 that has 124.8 at the rear. I have a bike motor being built as we speak and i am expecting somewhere around 130 rwhp depending on how the dyno goes it will be close or we may need to get a new ecm that is more programing friendly and more common than the race ECM buell makes. What i have found is that almost nobody is familiar with using ECM spy to tune on the dyno, They all want to swap to a better ECM or carb the bike so it can be tuned correctly. | ||

Large Fries with that? | ||

Tell us a little more about the V-Max... | ||

Preybird, steer away from those folks, ECM Spy on a dyno is not hard,(even I can do it!!) and pray tell, what other ECM is even available?? | ||

Apparently hd has one that is programmable but you have to have a race license, and i also heard there is one by thunder max that will work for buells but it is $899. | ||

I remember reading about ideas for using the delphi efi system from the newer xl's. Iirc the delphi system would require modding to change from cam pos sensor to a crank pos sensor, but it would be cool to see if such a project has ever been completed. | ||

+2 FMJ this man knows of what he speaks.... {Apparently hd has one that is programmable but you have to have a race license for the 1125 IIRC, NA for our motors FMJ and Co Are sponsors, too.. } (Message edited by Oldog on May 05, 2009) | ||

Its your cash bird, Tuning, adjusting mechanicals, fuel/air, and timing to get the desired characteristics from the machine. The premis as I understand it, put the machine on the dyno, set up the monitoring equipment ( exhaust gas ), and set the brake parameters as you test the engine under various loads, you create the desired condition, and you adjust fuel and timing for those conditions. with spy you open the program and adjust fueling values for the speed and throttle conditions. you may have to disconnect the o2 sensor, and or set and keep the afv at 100 you do a range of speeds and loads to try and aproximate driving conditions. there is limited to no adjustability for timing other than mechanical. why is that difficult? any one who can't change the values in the fueling table, may not be qualified to be a tuner. my 0.02$ | ||

Yes oldog jim is awesome. I would like to go to california and meet him and have him tune my bike further and set up my suspension when i get the new works shock. I just don't like carb's at all they have left me stranded on more than one occasion. | ||

PK, you were probably reading all the info I collected from John Self. He mentioned wanting to do that conversion on his X1 for a long time, and I had big plans to do that on my S2. Yes, the Delphi EFI is ten times better than the DDFI of any variant, but of requires a lot of work. One of these days I'll press to do the conversion again, but the consensus for me was that I missed out on my opportunity to do it cheap. I couldve gotten all the electronics and ECM needed for $400, including the XL wiring harness. One of these days I'll find that deal again when I have money. | ||

BTW, FMJ's turboed bonneville S2 is fitted with a crank positioning sensor and EFI, though I don't think it is Delphi. | ||

A bit late to give my impression of the Vmax. Well, it's like driving my 66 Mustang and my wifes Acura TLS. One is muscle, one is refined. The Vmax had a very upright seating position, very wide tank and it doesn't give a comfortable feeling when you twist the throttle. I was very fast, my friend was on an R1 which is supposed to be the fastest bike out there, but he didn't have anything on the Vmax. But it didn't make me feel comfortable sitting upright with the front tire trying to lift off the ground. If you cruise with your wife a lot or just like the looks, and have 19k to spend, it would be a great bike. But I would rather put another handful of money into my M2 and have my idea of the perfect bike. Many of you probably would agree. It was just an interesting comparison that made me even happier riding mine home.  | ||

Also, in the long run, is a carb model or Fuel injected the easier to get the most out of? Thinking about getting an X1 or XB. Give mine to the wife. But should probably just work on my M2. Thoughts? |
