CBR400RR NC29

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

Intro The short version is (spoiler duh): There are now two CBR400RR's in the shed. One race and one road. Most stuff would be relevant to either but for the specific bike you should see the Road/Race prefix on the title.   I had always had the CBR400RR as a road bike but on the back burners was the option to turn it to the track should I decide to enter a SS400 class. There was no such class in my club (CRMC) so I was in no hurry to do this so had focused on tidying the old girl up. This was the case up until recently when the CRMC changed the Constitution to allow machines up to 1994 in. There still wasn't a class but the likelihood of one coming up had suddenly grown. I was also well aware that I could race this bike at the Bob Mac' and at the Belgian TT Geddine (and many more) as well adding value to another track bike. In this time though the bike had gotten too nice to race so I searched for an alternative. I resisted Andy Greens suggestions to race the NSR

 Sorting the scruffy Bumblebee I kind of liked the yellow CBR400RR but the bodywork was scruffy so I started looking for a replacement. I had a number of options open to me from repairing what I had, OEM replacements and aftermarket replacements of various qualities. As this bike was never intended to be a painting I didn't want to spend loads so out the window went any plans for Tyga performance bodywork or anything else expensive.  I'm not convinced yellow was ever a factory option so it looked like a colour change might be in order without faffing with paint. As it turned out the bike made the decision for me when its left mid fairing flew off into a field on the way to work. Funnily enough this is exactly what happened on the last CBR400 I ran but this time I didn't find the misbehaving panel. So my hand had been forced and now I'm fairing shopping a little harder. I had decided on some pattern Chinese bodywork like on the NSR250 MC28 . they are c

This is another brief one. The clutch showed itself to be a bit worn on a track session with the British Superbike School at Blyton Park. When the crap tyres weren't slipping on the damp surface there was a noticable climb in revs occurring at peak power that wasn't sudden warp speed. It wasn't bad bt enough for me to take notice. A replacement race spec EBC SRK clutch was ordered and an evening set aside for the work. I had a clutch basket tool borrowed from Andy Green to hand so time to get to it. I know I photographed this but Christ knows where I put the images, I'm sure they will crop up and when they do I will update this blog entry. The job comprised of: Removing the right centre fairing Tip the bike to the left (keeps oil in the engine and off of the floor). Remove the clutch cover. Undo the pressure plate bolts. Swap friction plates(lightly lube plates as you go). Inspect Stator plates. Swap springs. Rebuild. Stand bike up. Top up oil that

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
