my nc30 rothmans project

[m6rk]

I thought i'd post up how far i'd got with it as you peeps have helped me a lot already :)

started like this



bleugh!!

poor thing... looks like a Picasso version of what a bike should look like

[m6rk]

humm this will be fun to drill and tap out not to mention new upper rad



clocks held on with electrical tape only bonus being a mph/kph motrax converter which aren't sold anymore and are like hens teeth, also means i don't need to restrict it :)



where the risers hit the tank.. nice...

[m6rk]

mmmm bodge tastic



looks like i get to try out my new parts washer then...



at least the forks look ok, and they are the newer model forks and shock



exhuast is a mess, sounds nice though

need to resize a load of the pics.. watch this space for the rest of it!!

So decided to busy myself with stripping it down..







spark plugs are tiiiiiiiny!



Then decided to do a little engineering.. only done 1 or 2 helicoils in the past.. but this one went well.. First used a 2mm drill to drill through the middle of the bolt.. Then a 4mm Tapped it out and found the hole has been ovalised so went with a M6 tap to replace the m5 bolt.. worked a treat.







Just waiting on a 41mm socket and I'll do the head bearings.. decided the frame isn't worth powercoating, will check on the condition of the swingarm next.

frustrating couple of days..

Front wheel is too foobar'd to fix.. located another for £82.. anonying but not the end of the world I guess. When the front arrives both wheels will go off to ze powercoaters.

Decided to continue the strip down of the rear end.. What a Bitch that was! everything was siezed, so brought out the big guns and a few hours later the swingarm and shock components were apart. The bolts were totally white with oxidation even with the nuts removed I needed to drift and twist them out..

windy gun and 41/46mm sockets were my friend and a special castle nut tool



chain angle grinded off



rear caliper might need some work



Some vandal's ripped half the splines off the chain adjuster.. I'm watching a complete swingarm on ebay, but i reckon there's enough left on this one should I not win it..



Complete hub ready for degrease

Small rockery in the swingarm



every bit of work i do and it's looking less like a bike... hopefully will get to put bits ON it soon



time to tackle the head bearings...

old ones were pitted and dead





removing the bottom race was a complete pain in the arse.. gave up in the end and attacked the bottom dust seal and race carefully with the grinder..



new races were taper bearings



and went in easily





Next job was caliper rebuild.

First the rear




tada!

then onto the fireblade calipers i'm fitting to it









Next job the swingarm

I bought a replacement swingarm off fleebay which was much better. However some cockend had cross threaded the nut which held on the sprocket carrier.. One big windy gun and air chisel later.. it was seperated, but i needed to use the axle of the original swingarm..

Much cleaning later, the hub bearings were good. But it needed new swingarm bearings. Linkage is gettng replaced with a jackup kit with new pressed bearings which i can't do at home. Collect those later in the week so the swingarm can be refitted.

bike looks quite sad without a swingarm



last job is to mask up and spray the discs as they are straight and can be reused.

That's some fine work you have going on there. Will be a great project to follow.
