96 RG125 restore

[Docker]

Hey guys, managed to pick up a 96 RG125 for £300 with spares which I will be working on over the next few months to get looking pretty and on the road.
Decided to get this as I thought it was a steal and I have been on the look out for a 2 stroke project and jumped at the chance for one with 33bhp (I have a restricted licence)

This is it currently:

Plus the fairings and loads of lose bits

This is what they look like finished:

That's gonna be a bit of work there mate!

Good luck to you though, should be good fun putting it back together.

Remember though, if the 10mm spanner doesn't work, standard procedure is to hit the bolt with said spanner, and swear for a while. Only then may you act rationally.

Also, keep your tea/coffee away from anything that creates dust - chrome flavoured tea don't taste pretty.

Always try n get the engine going as early as possible - that way you know where your at.

And the final picture has stretched a lot, making it look like a mini hayabusa set up for drag racing.

No meaning to piss on your BBQ, but are you sure that's a 96 model? The later models had a 'banana' swinging arm but yours looks to be straight.
Also 33bhp is optimistic for a mito / RS125, which are known to be more powerful than an NSR, which is known to be quicker than an RG. In great condition i'd say an RS125 is 28bhp, NSR 24bhp, RG 22bhp?
They did a 150cc version in thailand and i remember riding one felt pretty quick, though that might just have been relative to the speed everyone else was doing Might be worth seeing how much effort aquiring a 150 top end?

You sure it's not an import first registered in 96?

I've seen RS125 claimed power figures in the high 30's which seems to be based on people googling for a power figure than adding a bit cause they've got a K&N filter or 'race' exhaust. 28bhp is what you'd get from a good one running perfectly. near rebuild time or after someones attempts at making one go faster it'll drop from that.

Obviously they'll all be sold restricted to 12bhp so when you fix yours make sure you do whatever is needed to derestrict.

I bet you an RG FUN is a quicker bike than any of the official u.k. Honda NSR's and the u.k TZR's.

The Italian import NSR's and TZR's are a different thing altogether and then there were lots of spec changes year by year and also SP models too.

The RG is always said to be 1/2 an RGV250 engine, and it has a 30mm Flat slide carb which helps I would think. I'd be guessing 30bhp at the motor and 26-27bhp r/w.

There's no way it could be 22bhp at the engine for the speeds they are supposed to reach.

Hi

From memory they were easily derestricted. Just chop the black / white wire to the CDI.

All the best

Big power claims were made about the RGV250 too, but in standard trim they usually came out at about 50bhp or sometimes a tad over. So halving the engine would git ~25bhp which is a bit better than my 22bhp estimate

[Docker]

Once its done I will see my dyno man and have it tested for you all so we know for sure what it puts out either way people have recorded getting 100mph out of them, as long as it can do 85-90 im happy.

[Kickstart]

Hi

A true high 90s shouldn't be a major problem. Early AF1 managed 98mph in the road tests on 22hp (they had a fairly flexible power delivery)

All the best

Just bought this shed for £100 to store my project in

Sweet. Just remember that there's no such thing as too much light when you're doing a project. Also a heater will help massively both with motivation to go outside and with drying any paint

As I had the day off work and it was nice weather I decided to spend the day in it stripping the RG125, thats the longest part done, now I can begin the small cosmetic jobs.

Rgv250 top end will indeed bolt straight on ( you need to blank off one of the water ways) and the rg 125 was slightly lower tuned than the 250 to give a bit more torque for setting off. Early rgv250s made 45ish bhp on the dyno......55 ish with pipe and air box mods and 60+ with a bit of head work and blended power valves......talking of power valves....inspect yours closely for wear/ cracks and adjust them carefully as they as std are a weak point on these motors!.....shame for the 125 lot of today there are no more 2 t versions available

Another nice day so got the fairings out to have a proper look, gave them abit of a clean and got started on the sanding/filling.

Got the filler out on the two side panels and front mudguard so far

I'm going to continue using filler on the remaining fairings then ill sand them down properly and primer them to bring out any imperfections left to filler.

[Docker]

Today I sanded down both side panels and used a filler primer on them in order to bring out any blemishes I couldnt see, I plan on doing this a few times until ive got rid of all the imperfections and have them looking pretty again.

As my phone is broken at the moment I only managed to get a few pictures today.

This is the first filler primer coat I have done, as you can see it brought out new marks which I will be re-filling and re-priming.

[Frost]

Surely you should be sanding back to plastic rather than putting filler over paint?
Small imperfections are fixed using the primer rather than filler.
The cracks are because you've put the primer on too thick in one coat.

That looks like a paint reaction to me. I'd be tempted to get it smooth isolate over it all and try again
