The Yamaha Road Star Warrior Forum

Apples to oranges comparo here. With water cooling the vrod should smoke us with little trouble. Yes the warrior has the cubes but the air cooling severly limits our engine. The warrior is usually compaired to other bikes that are running liquid cooled engines aka vrod, any of the other brand rice bikes. That the warrior can not only run with them but beat them at times is a testiment to the superior engineering at the Star camp. For those of you who do not understand what a difference liquid cooling makes do your research before responding to my post.

The design of the V-Rod is much higher tech. Think about it. 107 hp (using average Dynojet hp numbers) from 1130cc is = 94.7 hp per liter. The Warrior at 1670cc making 75 ponies puts out a blistering 44.91 per liter.

I doubt many here who read the standard motorcycle magazines (Motorcyclist and Cycle World) would argue the V-Rod's power advantage. We've all read the quarter mile times and seen the quarter mile terminal speeds.

I guess what would prove the original statements made here would be some drag strip time slips and a dyno chart or two. Of course, I'm sure if he posts a chart showing a shite load of power there will be arguments saying the dyno is a 'happy' dyno. Or if it's low maybe the dyno is one that reads low.

Personally I am one who is looking forward to the graphs.

Congratulations.  Now share DETAILS of what you did to make your bike be able to walk away from a V-Rod that everyone generally accepts to be faster than a Warrior.  Could be that the rider of the V-Rod just isn't as good at racing as you are?  Maybe that's what happened when I walked away from a Warrior with my Harley?  I'm just sayin'... 

 

Ya the Germans did a great job on the V-Rod. It's pretty fast.

Shag:

Exactly.  I don't own a Warrior motorcycle anymore and my Harley just *barely* puts out enough power to walk away from a Warrior.  

 

ROFLMFAO!!!

i finally got to the dyno last friday. i was a bit dissapointed. it was a dynojet dyno. my bike registered 77.8hp at 4600rpms and 95.9 ft/lbs ot torque at 3150 rpms. the good news out of all this is the bike made more power when a fan was blowing air to the intake i made. it was a wind blast equivalent to about 35mph and it bumped me up to 79.7hp. the dyno guy said the bike was most likely making better power when its rolling. i guess its ok considering i have the 240 tire out back. i know the big wheel robs a bit of power.  i will tinker much more with it as soon as i put it away for the season. my air/fuel at higher rpms was around 11-1 so im gonna order the leaner needle for the carb. i suppose my v-rod buddy lacks a little balls when it comes to roll ons. i dont know what else to say. i hope the results make sense to you guys.

yes it all makes sense, your warrior is making below average power with a stage 1 set up, and your buddy on the v-rod is laughing his azz off .......dont feel bad. most here never believed it anyway. good luck with your carb build, nothing like going backwards on technology

I haven't tuned mine for all out competition yet but I'm at about 94 HP (at 5250 rpm)(SAE)  and 107.6 ft lbs of torque (at about 3500 rpm) and I would not expect to be walking away from a Vrod......

I did have a good showing with a bunch of sport bikes one night though ! See my post here

I have never EVER had anyone come into my dyno shop and tell me his bike is way slower than his buddies bike. I often have guys with built bikes come in and tell me how rocket ship fast their machine is compared to all their buddies and how no one in the area can keep up with them. Those are often the bikes that show less than spectacular results. For example, the supercharged H-D that came in and the owner said the manufacturer of the blower kit said he would make around 80 extra hp.

I asked him how much boost it made, he said 9 - 10 psi. I explained to him that:
a. 10 psi is 66% higher than ambient
b. Roots blowers are 50% efficient,
c. Thus expect about 33% more power
d Since his engine was probably making around 70-75 ponies naturally aspirated he should expect around 90 - 100 horses.

Almost on cue he told me how the manufacturer said it would me more like 150 horses. In addition his machine blew Hayabusas off the road.p>

First run was 93 horses. We finally got 99 ponies with carb jetting and ignition timing work. He was not entirely thrilled with the numbers, but couldn't understand how I could predict the power it was making or would make. In reality it's just math.

Personally I believe you walked away from the V-Rod more than I did before. If you're honest enough to post the numbers you just did then you were probably telling the truth about the race. It's not like we haven't all heard of a bike that makes less horsepower walking away from another one before. Even a couple of times in a row...

There's always a 1000 lb gorilla in the room of these conversations which never gets mentioned ... rider weight. Hp to weight ratios are completely critical to track coverage. And with the low vehicle weight of a motorcycle, the difference when one bike is sporting a 160lb rider and the other is lugging along with a 230 lb rider is HUGE!

So if you want to know what's really affecting the results of these street races, hit the scales and add the weight difference to all the formulations you're using to explain who's beating who!

Peace,

6'3" @256lbs ... I'm screwed. I need to race tanks.

When I beat those sport bikes , I'm guessing they ranged from 145- 180 lbs. and I was sitting at about 250.

I usually try to pass of these posts, but I am throwing a +1 to this. But there are so many variables you really cannot just pick one.

I am 6'2" just under 300 but I have smoked a couple v-rods...They were smaller guys, but they just could flat out not ride. They were older v-rods but even a new v-rod with a crap rider with no skills is going to get smoked. Heck I have seen my girl on here v-star 650 classic blast past a few people. Yes I said it. I have smoke 2 v-rods right here in Michigan. They caught up at the next gas station I pulled off and were cool about the fact they got left behind. But when I asked one of the dudes where were his RPM's he was shifting he could not answer. Was it the bikes, I am pretty sure we will never know. But I have to side with crap skills 

I guess the only time I really pay attention to these kind of posts is if it is in a controled enviroment. Similiar riders skill and size. I don't remember even getting smoked off the line by anyone riding two up. Even a rocket with two up is not going to chirp off the line as well. SO since I = 2 up. Doesn't mean I cannot stomp it, just that I sometimes may have a slight disadvantage that I have to make up with skill.

As far as this story. I am going to agree with shag. The man has posted his dyno results he doesn't seem like he is hiding something. Just seems like he was having a good day. Even recently I was screwing around with a buddy on his Triumph triple speed and I got him off the line and stayed there till about 50ish when after that I thought I was in reverse. Even he said he could not believe I jumped out like that. All I told him was, "thanks for doing a crap job getting off the line"

well, first off, thanks shag! i appreciate the vote of confidence. i was never lying about this whole thing. that being said, my buddy franky, (the v-rod rider) does weigh in at a hefty 306lbs. honestly, he told me how much he weighed the day i dynod the bike. he doesent look that heavy but why would he lie? my search for more power will continue. not sure which way i will be going but, i will keep the forum posted. for now, i gotta get working on my 280 single sided arm. -peace

Ok I'm going to put my two cents in here. I think on the 5th gear 60 mph roll on you could have beaten the vrod just because at 60 mph a warrior is running around 2000-2200 rpm if i remember right so you are closer to what i call your powerband, I feel my bike start to really move around 2600 rpm. But the poor vrod in 5th gear 60 mph isn't near its powerband. I like to think of vrods as crochrockets, because they have such a high rpm level they need to keep the rpms up to make there power. So maby try the warior in 5th gear and the vrod in 4th gear and that might make it more eaven. And as far as off the line I think you will get the jump but thats about it. And alot of these guys make great points about the other rider just cant ride, or weight o power ratio.

I want to see a V-MAX V-Rod drag race?!?!?!?!? they are both liquid cooled and high tech wonder who would win?!?!?!?!?!? LOL!!!!!!
