Funnily enough I was 30 when I bought this, must be a mid life crisis thing.

I Really Need Parts For My Bike

Dilusi · Borekit Bruiser Joined: 08 Oct 2006 Karma :

As requested a few more pics. Fitted and painted some parts this weekend and replaced a couple of dodgey connectors on the wiring loom. I'm not taking as much time as I'd liked over things as I'm trying to get as much done as possible before the extension on my house is finished. Ideally I need to get it on two wheels and running before then as I'll have too much work to do to spend any time on it.

what fuel tank you using?

because if its a 'f' tank i'd try and keep the 'f' clocks rather than R as the f tanks have fuel gauges on them and hold almost 1L extra fuel.

also for a little more poke up high you can chop the atac bolt shorter. i see you should have 2 like i do Very Happy

. can swap them around for sifferent styles of riding.just noticed teh allspeed pipe Very Happy

oh if you need a mudhuard i have 2 BRAND new white ones here Very Happy

I was going to use the black fuel tank as its in slightly better nick. Not sure if its from an F or an R. Can't use the F clocks I have as they are broken. Fuel gauge doesn't bother me as I've never owned a bike that had one, always used to just have a look in the tank to see how much fuel was in there.

Atac bolt?? Is that the one in the side of the cylinder barrel? Will the allspeed exhaust mean it's pretty much de-restricted? What restrictions did these bikes have

Might be interested in a mudguard, going to see if I can repair the one I've got first though.

Hi

They were restricted in the exhaust, plus not being fitted with the operating mechanism for the ATAC system.

Not sure that cutting the bolt down should help. The chamber is meant to be closed at high revs for full power. Cutting the bolt mean the chamber isn't closed which would mean it is in the low revs situation. Might well mean you have more low down power but you will lose top end power.

All the best

Thanks Keith,

Any idea what the jets should be to match the allspeed? Hopefully they are already the right ones but as it was seized when I bought it I'm not sure.

Kickstart · The Oracle Joined: 04 Feb 2002 Karma :

Hi

Afraid I am not sure on the jetting. Probably safest to go up a couple of sizes on the main jet and then work down.

All the best

What a great thread.
I got a NS125R last week and I'm still at the stripping down stage. I've never owned a bike before, so it's a steep learning curve for me.
Can I ask how much the powder coating was? I was thinking about it, but might just go with paint. (Incase the project goes belly up.)

Dilusi · Borekit Bruiser Joined: 08 Oct 2006 Karma :

Powder coating on the frame was £25 for silver, it would have only been £15 for black. Paint would have cost me that much for rattle cans. It did cost £35 for shot blasting though.

Cheers, let me know if you have one. Been trying to find a decent one on Ebay.

Just checked and the jets are standard, 110 main and 48 pilot. So you reckon a 120 is what I should use with the allspeed?

Needle looks a little bent too so may need replacing but can't read whats stamped on it.

Nice project. I wish I could be bothered to do as much as you. I have so little to finish my bike and yet I can't do it.

Did a bit more the last couple of nights. Made some brackets to fit the clocks and a few other bits and bobs. Need to modify the headlight cowl now to fit over the R clocks.

Bit more done yesterday.

Rear mudgaurd and swing arm fitted

Linkages sprayed

Need to get some new dust seals to fit the shock and and linkages. Also struggling to get the new lower bush in the linkage. Almost got it in yesterday using the draw bolt method but stripped the thread on th only bolt I had that was suitable.

I also started modifying the fairing to fit round the new clocks but haven't taken any pics yet.

Thanks, swing arm isn't perfect and is a slightly different colour than the frame but its not bad for rattle cans.

Recovered the seat today and I'm quite chuffed with it to be honest. Bought half a metre of black vinyl from Dunhelm for £3.49 and stapled it on. Going to try and make a strap to hide the indent from the old one.

Underside isn't pretty but its not like anyone will see it.
