SELEXON'S NC29 Pre Modern Racer
Posted: Fri Dec 10, 2010 2:53 am
Hi Guys,
Picked up this NC29 for okish money to start racing in a Pre Modern class that our Post Classic racing club now runs.
Just a quick run down on whats been done to the bike from previous owners.
1. Front Forks have Gold-Valves and the shim stacks are set-up for 70kg rider
2. Rear Shock is a CBR600 unit re valved. Looking at replacing with a Nitron unit.
3. Exhaust is a big bore 4-2-1 with a no name can. Have a Carbon Aka RSVR end can that may be shorten and used.
4.Thick core alloy race radiator.
3. HRC Copy Airbox.
After finding that the fuel pump had failed and setting up a mobile fuel tank to get it running the thing smoked like a two stroke.
So the decision was made to get in and have a good look around.
On inspection I found 2 of the inlet cam lobes damaged, exhaust ports full of sticky black oily carbon.
I haven't pulled the cases apart yet to check the rings but more then likely they will be shot as there is a bit of oil sitting on top of the pistons.
Here a a few photos of it striped down.
