(1 year warranty)

1. RAT can repair your worn or damaged cylinder back to stock piston size.
   
   
2. We first strip the old plating from your cylinder and assess the damage.
   
   
3. If your cylinder is only worn, we size the cylinder to a new stock piston.
   
   
4. If your cylinder has any scratched, grooves, or cracks, we weld the damage so the cylinder can remain stock.
   
   
5. If you're looking for more horsepower, we can bore your cylinder to fit an oversized piston.
   
   
   • When big boring a cylinder the existing port angles are machined away. To restore the proper porting angles, you have a couple of options.
     
     
     1. For increased horsepower we can match the ports.
        
        
     2. For maximum horsepower we can do a full port job.
        
        
     3. You can leave the ports as-is, however you will not get the full benefit of the big bore kit.
        
        
6. Before plating your cylinder we chamfer all ports so there are no sharp edges to catch the piston rings on after plating.
   
   
7. We then plate your cylinder with durable high-quality nickel. The cylinder is then honed on our precision, self-centering honing bar with diamond cutting bits. The result is a cylinder that is straight with precise piston-to-cylinder wall clearances.
   
   
8. For the final step we chamfer the ports again to remove any plating buildup on the port edges, removing any sharp edges for the rings to catch on.
   
   
9. After gapping the rings for proper clearance, your cylinder is shipped back to you, ready to race.
   
   
10. Our average turnaround is 6 to 8 days so you'll be up and running in no time. Click here for our current turnaround time.
    
    
11. If you need gaskets, plugs, sprockets, etc., we can ship them out with your cylinder. Just let us know what you need.
