Suzuki RG125UN wolf project MK2.

Been a while since I've been on here but I've bought another little project. It's an import, French or Swiss, I meant to just get it running & blast around on it during the summer but I couldn't source a spark plug locally so decided to strip it. It has been bodged to buggery & a lot of the fittings are missing but the engine is in good nick & still pumps out over 100psi compression. Will update the thread as I go. Thumbs Up

That was how it looked when I picked it up. But when I couldn't get a plug for it I decided to just strip it.

I've already ordered another headlamp as the hockey mask monstrosity has to go. Ordered quite a lot of parts already I'll hopefully have it done for the summer.

Nice project, and so is AF1 project too!

Ben what happened to that nice white one you built up? Did you ever get the RG150 top end fitted and working on it?

Good luck with this one, there's very few RG125F's around now, much more rare than NSR's or TZR's as is the TS125R compared to rivals.

Got some more stripping done today only to find the forks are actually bent! Rolling Eyes

I don't know if it shows in this photo.

Also found out why the bike was being run on pre-mix.

All for the sake of a cable that costs 12 quid Rolling Eyes

.

I ordered an SV650 rear shock which turned up during the week & with the help of some cheap spring compressors I took it apart for blasting & paint.

How do you mean you couldn't get a plug for it? Oh and RGV 250 barrel fits them as do the power valves ! Slightly higher state of tune on the 250 top end as twice the cc makes setting off from the line a bit easier! Check them power valves for wear or cracking or your in for ££££ rebuild costs but if you look after them and if needed change the pin and make sure they are adjusted correctly then damn good little bike.........shame you can't buy a 125 that does 90 mph+ anymore .....oh and the 125 had straight plug heads and power valve breather that was a race kit add on for the rgv250 so well sought after by those that race 250 2t class!

Hi all a small update. I've dropped the frame, fork legs & all the smalls off to be shot blasted & powder coated & I've been collecting parts:

Also bought myself one of these:

https://i59.photobucket.com/albums/g308/bennyboy73/IMGP1719.jpg

23 quid delivered from eBay. Thumbs Up

It'll do for working on the engine. Speaking of which whilst I'm waiting for the frame & assorted parts to be done I thought I'd crack on with it.

https://i59.photobucket.com/albums/g308/bennyboy73/IMGP1720.jpg

I took the head off & everything looked good:

https://i59.photobucket.com/albums/g308/bennyboy73/IMGP1723.jpg

Then when I actually got the barrel off the truth emerged:

https://i59.photobucket.com/albums/g308/bennyboy73/IMGP1724.jpg

As you can see the piston is totally screwed. Thumbs Down

This in turn has knackered the barrel. It looks as though rather than replacing with a new piston kit a previous owner has just replaced the rings. Rolling Eyes

https://i59.photobucket.com/albums/g308/bennyboy73/IMGP1725.jpg

Still there is some good news there's no vertical movement on the con-rod & the big end bearings look in really good condition & no swarf. The powervalves are intact & move freely. I'll get the barrel & head off to PJME next week. Thumbs Up

Stuff back from the coaters looks nice. Good luck with the rest of it. I had an rg125r also, PJME is a legend Thumbs Up

Well I received the head/barrel back from PJME today & all I can say is I'm extremely impressed. They both look like brand new, very very happy. Photo's to follow. Dance!

Ok so progress is slow at the moment but here's a few pics.

I finally got around to painting the rear shock.

https://i59.photobucket.com/albums/g308/bennyboy73/IMGP1729.jpg

I was going to do the bottom mount black but I already had some chrome effect spray lying around so went with that.

Put it back together so it now look like this.

https://i59.photobucket.com/albums/g308/bennyboy73/IMGP1732.jpg

Ordered a few more parts, 37 quid for this little lot! Shocked

Some pics of the barrel post re-plate.

My old bike (the white one) is now on eBay -> eBay ad I'm glad it still looks in fine fettle although not white anymore. I'm a bit dubious of the amount of "work" he's done on it as all that's changed is the bellypan is missing it's been resprayed & stainless steel hoses fitted. Rolling Eyes

It's way over priced as well.

Hey, it's nice to see your old white one is still around! Thumbs Up

I wonder why it was re-sprayed again though? It does look pretty nice still and as you say they are pretty rare now. You don't see many of the fully faired versions now either.

BTW what is that round hole in the side of the cylinder barrel for? It looks like a core plug?

Hope your new project is still going well too mate!

That's a fantastic job done on that shock, looks amazing.
