Hello all,  
  
I am new to this forum and (hopefully) about to buy my first trial. A friend of mine offered me his 2001 beta rev 3 250 for a good price and I am tempted to buy it. However he said that it needs some maintenance/repair and I am having troubles to estimate how much money and time this would require. According to him the following things need to be addressed/changed: 
  
- replace chain 
- clutch is stuck (though i found some solutions for that here in the forum) 
- Air and oil filter 
- spark plug 
- brakes need to be bleed 
- Suspension service 
  
  
I have no former experience with motos or engines in general but I am comfortable servicing my mountain bikes (brakes, forks, gears...). 
  
I assume that most of the things are rather easy to fix. I am worried about the clutch. Any ideas how much I d need to invest to get it up and running again ? 
  
Thanks for any comment !
