Mick and Capt.

I don't have a copy, but it's the April '97 issue

Bingo!!!! Get that man a prize

 

Sweet, thanks RK. By the way anyone race it?

 

Ha! I love prizes! I'd settle for a post with the VTR performance data from that article if anybody finds it.

 

I'll post it when I get a few minutes of uninterrupted time (very scarce these days).

cheers

 

so whats it supposed to run? evryone says that fuel doesnt matter as long as compression and timing isnt bumped. i personally try to always feed mine 94

 

its funny. im seeing mixed mphs depending on where i go. and from my drag racing background it would just make sense that a bike trapping 10 mph more would pull away from the sh. but that doesnt always seem to be the case. ive got a buddy with an 02ish i think cbr600 and hes lighter than me. a bike which pulls a higher trap speed out of its ***. and yet i out run him. ive also got a friend with a 2010 triumph daytona 675. again a bike that should pull me, and stock for stock id put a few lengths on him every time we'd do a pull from any speed. mind you now he tossed on an exhaust and tuned it and pulls on me, but that should change this year as my mod list went from power robbing bafflectomy to whats listed below. but still bikes that are pulling higher mphs are going down to the sh. kind of weird the way it works, and all of these guys have been riding longer than me. but youre right, ive been on a few new 600's and they feel weak in the power department. i took my buddys brand new gixxer 600 for a test ride and wasnt really impressed with it. maybe its just the butt dyno and their lack of torque vs the sh's instant power at any rpm that makes it feel like it isnt pulling as hard.

 

I run 87 octane in mine (this despite decked heads and Stage 1 cams, and living right at sea level, where air density is the highest). Running octane rating above what is required to prevent pre-ignitiona dn detonation only results in a slower burn and reduced power. I recall a chap doing a test on a Ski-Doo MXZ700 snowmobile (granted, a two-stroke but an irelevant factor in this case) which was delivered to run on 87 octane. When dynoed with 91, he lost 2 hp. This engine produce very similar power to a VTR so I would expect the power loss from running premium to be similar.

 

Before this turns into another Regular vs. Premium...

Good point. How could we forget the other two essential topics:
- what oil to use?
- which is the fastest colour?

 

Very true, can't forget those. They will definitely play a factor in the outcome of this bench racing.

As far as I can tell, his SH is at a disadvantage due to it not being YELLOW, the fastest color.

I hope he's running the most expensive super slippery synthetic oil he can get his hands on.

 

I don't think that a few octane points will make that big of a difference. Mine felt like it ran worse on 89 and I'm about 200 feet aboce sea level.

Anyways I'm curious to see the outcome. Ill agree yellow is the fastest color especially if you scream vvvvvtttteeeeeeeeeeeeccccccccccccccc at 7k it'll add 15 more hp

 

Not too slippery though, or it`ll make his clutch slip (unless, of course, you are referring to the chap with the FZ1, in which you should recommend he use "energy conserving oil" for the documented benefits of the moly ).... I am surprised no one has mentioned the documented benefits of the famous flux capacitor, add one of those babies and you`re a shoe-in for the top step on the podium....

 

Well, the dyno detected 2 hp on a sled engine..... noticeable while riding? likely not, but 2 hp here, and 2 hp there, and it soon does become noticeable..... I ran mine on 87, 89 and 91 and saw no difference in running quality so I now run 87, keeps my wallet in better shape...

 

I'm right there with you. I know mine idles better on 87 and unless you up the compression ratio there is no need for any higher octane rating. Like you my info comes from dyno runs and trying all of them in the 12 1\2 years I've had my SH but I am just a guy on the internet so as always YMMV.

Oh and I still haven't made it over to Dans shop been dealing with swingarm issues but should going within a week so I'll get back to you with any info I can squeeze out of the grumpy ol' Brit.

 

if you switch bikes with your buddies on the 600 and 675 for a drag race, you need to get pissed, I mean mad as hell, like you want to blow their motors to hell. Then scream them babies till you are appraoching 16 on the tach before you full throttle shift and then you'll see your yellow SH in the mirror. Now don't tell them to do this bike. hahahahaha

 

So anyway we haven't raced yet. I need a new rear tire and my CCT's scare the crap out of me. However today we left work together and we were at a light and I told him hey let me roll out in front a little so he said cool. I rolled out about 30 feet after light turned green and twisted hard on throttle did a twelve oclock for a second and at the next light he was grinning. I told him sick huh and he said yeah im scared to do that. He is my good friend and I just wanted to give him a taste of what's to come. Oh by the way my orig post I went from cruiser to sport but I have had about ten sportbikes before that. I guess I forgot to mention that and I have been drag racing about a few hundred times. LOL. Rider is going to take this race. HAHAHAHA I can't wait. Tires and CCT's holding me back. I love my Hawk.

 

I smoke my buddies VTR every single time we race when Im riding my old 1999 gsxr600. That 600 keeps up with the new crop down the straight away at our race track though, its geared short and runs great.

Just gotta know how to ride them, I launch that thing at 11000rpm Ive ragged that bike for 40,000km before selling it and it still hasnt had any issues.
