As per my "anyone ride off road" thread, I recently picked up a 2003 Beta Rev 3. The Rev 3 was a long running, capable and successful trials bike and has a wealth of parts available off the shelf. With regular maintenance it is still capable of much more than the average rider, and you still see them used in great numbers on clubman events around the country - hence my choice.

I picked this one up for... well, let's just say after some negotiations it cost me about half of what a reasonable Rev 3 of this age should cost.

On first inspection the bike is obviously tatty, tired and neglected - as most off road bikes tend to get when they hit this price point.

After a brief inspection it was hurled into the back of the car and driven home:

I'm not a bike expert, but as far as I can see it wants the following:
Rear tyre - advertised as "cracked but holds air" is utterly knackered
Chain - in urgent need of lubrication, possibly replacement
Front brake - Master cylinder leaking, caliper seized solid
Brake levers - Adjusters missing so the levers flap about in the wind
Plastics - In horrendous condition, deep scratches, faded/discoloured, covered in insulating tape. No cracks which is good.
Clutch - Works fine but the master cylinder is weeping
Fluids - All need draining and refilling at a minimum before I know anything else
Handlebars - Bent
Handlebar grips - Awful motocross things falling to bits

So that little lot should keep me busy. Some of it doesn't really need doing, like the bodywork, but I'd like to at least feel something positive when I look at it so it's getting done.
Once it's back together I'll put some hours on it and see what else needs doing.

First thing was an expensive visit to Trials and Tribulations for some parts and some very helpful advice from the bloke who owns the shop.

Michelin X11 rear tyre
Disc guard
Master cylinder rebuild kit
Caliper rebuild kit (pistons & seals)

Also picked up some plastic primer, fluorescent red paint and flexible polyurethane lacquer to give the bodywork a bit of a refresh.

After lots and lots of sanding, 3 coats of white plastic primer, 3 top coats and 4 coats of lacquer this is what I was left with:

I know on the grand scheme it wasn't an important job, but for £20 and some effort it makes me feel a lot more positive about the bike.
I also know that it's all going to get beaten up and scuffed again, but hey ho!
The camera doesn't do the colour justice - it's properly vibrant and outdoor it looks awesome :cool:
 
Cheers, reasonably happy with how it turned out - the red matches the factory decals pretty well:

Turns out all that insulating tape was doing.... nothing at all. One mounting point was enlarged, the bolt had pulled through - that's been repaired with epoxy adhesive and a guitar plectrum and is now as good as new.

Rear tyre feels like it's made of chewing gum compared to the rock hard old one, not looking forward to changing it though:

Jobs done:
Bodywork painted
Master cylinders rebuilt
Brake & clutch levers sorted
Handlebars replaced

Jobs to do:
Refit bodywork
Swap rear tyre
Rebuild front caliper
Fluid change
Remove frame decals
Decals - not sure what to do about these. I'd like to give it a refresh with some white and blue Evo style graphics but they aren't designed with the Rev seat unit/mudguard in mind. I'd like to design some but even basic vector shapes are beyond my limited design abilities :o

Yeah, having somewhere to ride can be an issue with bikes like these. They can be road registered but they're not exactly built for the commute.

This weekend will see the rebuild of the front caliper, my new grips should have arrived, and hopefully I'll be able to replace that rear tyre - never done a bike tyre before.

Some trials, the sections can be spread out and can only be accessed via a road. So these trials you have to have a road legal bike to compete

Test fit of some of the plastics. Camera does not do the colour justice, it's blisteringly bright

Next steps - get those frame stickers off.
 
Yeah the Michelin tyres are soft, but considered the best. I have pirelli mt43's on mine are they are to hard. It came with them, as their new and I'm learning, I thought I'll leave them on for now.
Get some long tyre levers and its not that hard to change them.

Bleeding the front brake - OH MY CHRIST what a pain in the backside job this is! Need to dig out my vacuum bleeder, getting nowhere fast with conventional bleeding methods.
 
Front brake bled, the bike now stops.

Had to use a syringe and inject the fluid from the caliper in the end, even a pressure bleeder was having none of it.

And now I've noticed the clutch cylinder is leaking. FML!

Front end rebuilt:
Brake master cylinder stripped and rebuilt with new seals, springs & plunger
Clutch master cylinder stripped and rebuilt with new seals, springs & plunger
Brake caliper stripped and rebuilt with new seals, pistons & pads
Handlebars (bent) replaced with unbent ones
New disc guard
Forks painted (which will all get scratched off anyway :o )
Mudguard painted
Wheel spindle regreased
Front tyre needs to wait until next year. This one has plenty of tread but it's old, so in January it will get a new Michelin to match the rear.

I'm away this weekend but hopefully on Monday I'll get the new rear tyre on (took the old one off last week with just a pair of levers and some washing up liquid, easier than I thought)

After that she will be ready to ride :)
 
Yeah, major potential issue on an off road bike - I've got a pair of those poncey anodised ones that look like pistons :o
 
Rear tyre fitted (would never have got that on without my Yoomee tyre beader)
Bike reassembled and test ridden.

Clutch is a bit grabby and some minor bits and bobs still need doing but essentially it runs and rides again, great fun!

Think it looks a lot better than when I picked it up :)

So an update on this.

Basically I rode it about until September. Fell off it a lot and generally learned loads.

Then disaster struck. Where the air box lid securing nut should be (captive nut) the previous owner had replaced the broken captive nut with a replacement, that I think was glued or Araldited into place. At some point the nut and washer fell off into the air box and eventually got ingested - smashed the piston and rings to smitherines and chipped the barrel.

I bought a new Evo Factory so that I could keep riding but elected to also rebuild the Rev 3, planning to sell it when finished. Watch this space for pics and updates....
