Re: Billing's Bikes
Sam, my NC24 slides have come today :DBillingCBR wrote:Nothing changed, still clattering and knocking, so fearing the big end has gone bang, so stripped the bike down to see if it was something simple like a loose shim or something. Nothing obviously out of place, so fitted my RVF cams and put the tops back together (first time taking cams out of a V4, wasn't too scary, and setting the cams was a doddle, thanks Honda!)
While I have the carbs off I decided to clean them up a bit and do some of the jobs I wanted to but couldn't be bothered to strip the bike down to do them they were that minor. Double checked the pilot screws were set to 2.5t out, and fitted my NC24 slides with J51 A and B needles and an extra .5mm washer.
Couple of pics from the last few days;
My view from my bedroom door
Spark plug colours in the rear cylinders
Slides, Jap NC30 on the left, stock NC24 on the right.
As you can see the NC24 slide is higher, with 2 small holes instead of 1 also small hole. The needle exits the slide at the same height, the sides have just been pulled down a bit to smooth off the venturi at WOT hopefully it'll make a tiny difference in throttle response, and a bigger difference if I start going big power :)
did you feel any difference?
mine only have 1 hole in and not the two like yours,

Re: Billing's Bikes
Hey Ricky,
I didn't notice any immediate difference as the engine was kaput, but what I have noticed is it's a bit better at the top end, it used to struggle to 130 on the old engine and setup, but now it zips up there and has plenty to go :)
Don't know what the difference is between the 2, maybe they're a slight change in the years, or yours are actual HRC?

Re: Billing's Bikes
Still fiddling with things, going to grab a pic of the rearsets tomorrow after I clean the bike 
I put a new map on the Ignitech, HRC -1, it seems to pick up a little better than the stock +2 I had on there :)
Does anyone know if you can write a program into the CDI to make the tacho needle do the cool flippy roundy thing? Stupid I know, but it would entertain me

Re: Billing's Bikes
You mean when you switch the ignition on and the needle spins round?
