Road: Going back to ignition

This one is short and sweat, a simple bolt in mod in fact.
The stock ignition has a hard red line, top speed restrictor and a restrictive ignition curve that an HRC ignition unit would sort right out along with associated HRC mods.
Clearly these mods aren't about anymore but GF Racing UK have you covered with their fully programmable plug in ECU which conveniently comes with the HRC map already installed.
I ordered mine after the dyno runs  previously mentioned and very quickly got an email from the owner of GFR. He didn't have an ECU in stock and offered to lend me his unit from his own bike! I was in no hurry for it so thanked him and waited patiently (what a guy though!).
When the box did arrive, fitting up was a pretty easy process:

  • Remove tail fairing on LHS.
  • unplug and remove stock ECU.
  • Fit GFR ECU under OEM ECU rubber boot.
  • Plug in GFR ECU.
  • Reassemble fairings.
Then all all I needed to do was chuck my kit on and go ring the little CBR's neck!
The bike now felt a bit more eager to rev but more noticeable was the increased revs you now have to play with. In low gears this can be a bit dangerous as the bike develops power right up there and if you aren't paying enough attention you can find the bike revving a bit more than you might want on your daily commute.
The other restriction that is removed is the top speed. Now the bike just keeps accelerating in 6th to as fast as the road and engine will let you go.  Not something you really need for the road but indispensable should I decide to track the bike.

Race: Other engines for the NC29 chassis?

Image
The " From Road rashed to race " Blog entry very quickly got a bit out of hand so I have removed some detail and made it more of a story. The real bones of any particular job, such as this one, are now in separate blogs which I will link between whenever relevant. This should make it easier to find useful info whilst still getting it all down. Seeing as I had the engine out of the bike during my initial strip down, it seemed like a good idea to drag out one of the spare engines I had bought to see what the differences were and if they would fit in the NC29 chassis as the forums seemed to suggest. I had a choice of an NC23 motor which would need different carbs due to different inlet port spacing or another NC23 motor with NC29 heads which seemed okay for a straight swap should I decide to go down that root. I picked the NC29 head/NC23 case' hybrid as this should be most similar to play spot the difference. Turns out quite a lot.  Engine mounts are differen

Stuff that fits the CBR400 NC29 v1.1.2 060120

Early NC23 on left with NC29 head NC36 engine right. Intro This blog entry is to list and share what will fit the CBR400RR-L NC29. I have mostly collated it for cross compatibility of NC23 parts as such I will also have a list on parts that do not fit from this machine. I will also list items such as fuel pumps that will fit from other models but clearly aim not going to tell you that an AUDI A4 door does or does not fit, because that would be silly. It doesn't by the way, you can have that one. I will update this periodically as I find things that do or do not fit and update the version number as I go. All of the latest updates will be in red. Engine Stuff: Engine code: NC23E102xxx CBR400RR NC23 1988 Too far forward & low Different upper mount The engine is not a straight bolt in. The spacing is substantially different at the rear with the rear barrel mount missing. The case rear upper mount is too high and aft so it fowls the water tank before far

Racing: Cartridge Forks, R is for Racing! *In progress 20/10/20*

This is a work in progress but as the blog is being written at the same time as I am working (for a change), I thought I might as well publish it to make it a live update of sorts. So do pop back in the future to see when I finally give up and set the lot on fire. The " From Road rashed to race " Blog entry very quickly got a bit out of hand so I have removed some detail and made it more of a story. The real bones of any particular job, such as this one, are now in separate blogs which I will link between whenever relevant. This should make it easier to find useful info whilst still getting it all down. During the time I spent fart assing with engines, for the bikes strip down, I had spent a lot of time head scratching on the computer. Some of that time was on ebay and in doing so I had found the odd useful part. One in particular was a set of forks. They were listed as tidy but missing a damper rod and listed at a fairly low price as a result. Nothing remarkable there
