New to the dirt bike scene! 1991 CR125

[DrunkenMistake]

So I have finally got my hands on a 91 cr 125, needs a couple of things fixed up, Rear brake needs some attention I suspect its a stuck piston, and the front brake lever needs replacing, it also needs the rear tyre tube repaired and rear tyre replaced,
It came with 12 spare tyres front and back all different conditions, god knows why it has 12 tyres but never mind!
This is going to be a bike to take on a few trails and for a fang in the dirt, so no competition stuff, and its a bit of a long term tidy up project,

What I want to know, is if anyone has any handy tips as what to use as tyre irons, I have herd of big flat head screw drivers filed down and rounded and bent used as tyre irons has anyone tried this?

Also curious if anyone has any idea how many hours roughly I might get out of a tank of gas?

and maybe some handy do's and don'ts when it comes to taking it for a thrashing and what have you.

Cheers guys.

I suggest using tire irons as tire irons....

You can certainly get away with using flat heads but why wreck your screw drivers and still get a less than satisfactory tool...

Check these out on sale - I've got the exact same pair in one of my tool boxes and they are all you should ever need.

As far as the gas goes it is entirely down to how you ride it. But keep in mind the going out riding for 5 hours with friends you will probably actually do approx 2-3 hours of riding and a bunch of waiting and shit talking. And this sort of trip should be acheivable on a tank of gas.

Get some proper tire irons/spoons and a rubber mallet, to be honest the cost of getting a tire fitted in a shop as opposed wrecking a tube is less hassle.
First things to do give it a service new air filter, gear box oil, spark plug.
Next strip and lube the suspension linkages. swing arm bearings. Change the fork oil and get the shock serviced. Replace the brake fluid and pads, check chain and sprockets for wear.
You should get up to 1 1/2 hrs on a tank if trail riding half that if your racing hard out.

+1 to they tyre levers idea, they make way better tyre levers than screw drivers do...

+1 to lubing the swingarm and linkage, also check and lube the wheel and head bearings.

Engine-wise, do a piston and rings if their current lifetime is unknown, not sure if the 91 had powervalves but if so, check that they operate correctly. Change the gearbox oil and radiator fluid too. Give the brakes a good going over, clean out any corrosion on the piston etc.

Fuel hours depends completely on the riding, you get a lot less on a track that you do on a farm! I'd expect it to be good for trail ride half day length anyway, most of em have refueling options at lunch iirc.

Make sure you have a few spare parts with you too, couple of clean plugs (2Ts love to foul em on trail rides with novice riders), few levers, spare bolts and spanners etc in case of some plastic mishaps.

Also, 12 spare tyres, and a man who needs practice at changing them, skids time anyone? :bleh:

What he said, especially the maintenance stuff.

Regarding tyre changing, I keep two of the blue levers that RITTR indicated and one drc spoon which I got from my local bike shop for <$30 which is better for getting under the tyre. Also use the bead breaker set up which you can get off torpedo7 for $60 on special - http://www.torpedo7.co.nz/products/T7TO4N1TB/title/torpedo7-portable-tyre-changer-with-bead-breaker
