Those i-factory exhausts are cool (and sound good too).

Fight, Fight !

Very Happy

Those I-Factory's do look good Rich, prefer them to the DFR's,


Fight, Fight !

Laughing

BTW, I did notice he was running just a standard card - he also owns the RGVr if you've watched the other vid's.

Harsh but fair.

I'll take a guess, if it's got the HRC card...58bhp, if not...51....either way spanked senseless by a stock wirespliced '18 or '21 Wink

And that comment was before I'd even seen the other video!

Put my 21 or Steve's F-III on that dyno and it would probably (falsely of course) show about 90hp as it span the back wheel up! Laughing Only a '28 could be run without strapping it down! ROTFLMAO

Had that been my bike, after about the 25th or 30th time it was revved like that I surely would have grabbed a stick, rock, or small animal running around and beat him to death with it! AAAAAAAAAAAARRRRRRRRRGGGG!

You wouldn't want to see Steve run mine up then! Poor old nsr.monkey was almost crying on the first ever dyno day when Steve really ran mine up! Remember that Fontyyy?

I do admit though, those i-Factory pipes do sound nice.

Really? Do you honestly need to "blip" it like that a gazillion times to get a good run? RING, RING, RING, RING, RING, RING, RING, RING, RING, RING, RING.......

RING, RING!!!!!!!!

Oh goodness, you'd have to strap ME down, not the bike! haha!

Not if it's well set up. It sounds like he's trying to keep it clear for the run. (Especially when you listen to how rough it is in the other video!)

Steve only blips them during warmup and as he shuts the throttle off at 12000rpm after a run to keep the pistons/bores well lubed.

He canes the crap out of mine because we think it's funny! Very Happy

It won't (shouldn't) hurt it. It'll get worse (a lot worse) on the track and if it doesn't you're not trying hard enough!

Andy's bike on the GT Dyno way back was funny, IIRC that was when the crank seals were on the way out and we all thought (hoped) it was something else. Steve just made sure (very very sure) it was clear.

Nope, it was on the new motor... the motor that initially did 4 miles to the dyno to run it in and then got a good seeing to! Very Happy

There wasn't even any need to run it on that dyno day other than for comedy value! Can't say you don't get your money's worth out of us! Very Happy
