NC29 Race engine project

[greggo]

The engine and frame in one place together. A big moment in the build...


So I finished the clutch, doing up the centre nut with the rattle gun and using thread lock as there is no where to stake the nut.

I then put in the cams without silencer gears, the one with the blue plate is the one I did using a 2mm thick pressure plate and 3 4mm Stainless bolts to hold the gear in place. The one on the right is the one that was already in the engine, and uses 3 5mm bolts with no pressure plate.



Once the cams were in I checked the valve clearances, and all were within tolerance. There were a couple that could do with sorting as they were right at the limit. But the plan is to have the cam cover off after the bike has been run in so I will recheck and do them then. I also threw in a new set of plugs while it was easy.

With the engine all sealed up into the frame it went! Piece of cake. Rear mount first, then tilt the engine up an you are away. The R&G crash bungs are a well made piece of kit! With the engine in the exhaust went on. I decided to use the set I got from Sam Hornsey, the link pipe to the muffler and the muffler have been down, but it has a plug for a Lambda sensor and I would like to get my hands on one to help with tuning. New gaskets, new engine case bolts (stainless), everything looking good so far!!!! You can see I need to fabricate a new exhaust hanger, as the muffler doesn't sit in the same place with this set.



Once the exhaust was on, I fitted the Samco hoses that I needed for my R1 radiator. I've used the flexi hose as my two link pipes to the rad are unique.





After that I laid the bare loom over the bike and called it a day. Another concerted effert next weekend should see her fire up for the first tinme! I'm getting excited. Though there are lots of littel jobs yet to do!!!!

Wow, looking good greggo! Youre making it look real easy there.

IT IS ALIVE!!!!!!!!

I figured after yesterdays effort there wasn't much I had to do to hear it run. So before I went to sleep last night I made a mental list of things to do before starting it, so I could hear it run.

I plugged in all my connectors, which meant soldering on a couple for the oil, neutral and temp senders. Then plug in battery, relay, fuel pump and ignition pick ups. All easy stuff, a quick check of the wiring diagram to remind me and it was plug 'n' play.
I mounted the carbs, I seem to remember someone telling me you had to grind the frame to get the flat slides on. Rubbish. I didn't! So with the carbs on and the electrics plugged in I hit the run switch (mine runs from the run/off ignition switch).

And....

...Nothing. Ummmm. A few moments of blank staring and blinking I realised the dash wasn't plugged in. PLug, plug, plug and badabing I got lights. Press the button I got whirry clickety clicky of the started and everything seemed right. So I sucked some petrol out of my friends van into a jar and attached a funnel where a petrol tank would normally go. I figured it would take a while to start and suck the fuel through, and there was no risk of it starting before the oil had a chance to circulate. I was right.

Took some cranking and she fired up easy. Not sounding right, and cylinders one and two weren't firing. Ummm...

....A quick check with the voltmeter and I'd put the coil for plug number 1 in cylinder number two and vice versa (remember this bike runs stick coils off an R1). A quick job with the electrical tape and they were in the right spot. Start the bike and BROOM! She's a runner. Had a fiddle with the new tacho so it is reading the revs right, and calibrated a few of the sensors. Everything is working. Sounds spot on, no missing or farting, everything is oil tight, but there is a water leak out of the old hose from the water pump to the oil cooler. An easy fix, i'll use some of SAMCO stuff for it, but not today.
Starting to look dead sexy with some clothes on!






For the rest of the day I fixed up a few little things. Started wrapping the loom but ran out of tape half way. Modified the exhaust bracket so the muffler hangs properly. Fitted the gear lever. And then spent some time diagnosing a busted alternator on my friends car.

All that is left is small jobs, some will take a fair amount of time, like mounting the front guard (its off a CBR600 F4i), iftting brakes, chains, wheels, etc etc.

Hi Greggo,the exhaust has a Lambda sensor in because it was made from an R6 exhaust.

[cajun]

Greggo, so you are saying stock R1 coils will work on a NC29 engine? The reason I ask is because I am building mine basically from scratch and the coils are shit. Which years? 99-02 i would assume.

[greggo]

Nope, I'm using 04-06 stick coils. All you need to do is make sure the PAIR of stick coils has the same impedence as the stock coil pack. The r1 stick coils are a tight fit in the cylinder and cam cover but I ran them all last season with zero issues. If you want more info I will post the wiring drawing etc later in the week.

[cajun]

Oh ok, so coils for an injected bike on this one? But yeah if you could post what I would need that would kick ass.

Are these what I would need? http://cgi.ebay.com/ebaymotors/06-Yamah ... ccessories" onclick="window.open(this.href);return false;

[greggo]

Yep, those are the jiggers alright. It's handy if you can score them with the 'sub loom' as that has the plugs.

But it can be done without them (I have one set with, one without).

[tanuki]

mate that is an awesome job you have done there...

Hope she goes as sweet as you are hoping...

[cajun]

Ok........ So these will work??? And how do you plug them in to the existing wiring? Is it a straight plug and play or what? I'm just tryin to find out before I buy these. Thanks again Greggo
