***PLEASE NOTE***

You may need to match your power-valve to the liner, as the new liners are bigger than the standard barrel.

We can offer this service for £25 extra or you’re welcome to do this yourself by filing your old power-valve.

Any barrel re-sleeved or rebored to suit a new Mitaka piston & Mitaka/Winderosa top end gasket kit.

For these unbelievable prices...
  • 60/65cc (KX Only) - £235
  • 80/85cc - £244
  • 100/125/144/150cc - £254
  • 200/250cc - £274
  • 300cc - £280
  • Rebore alone - £65
Wossner, Namura, Pro-X or Wiseco pistons can be supplied at an extra cost. The same applies with gaskets kits.

Powervalve reassembly FROM £15

You will be required to post your barrel to us and from there, the service takes around 4 weeks to complete (the service can take longer during busy periods) - THIS IS THE TIME FROM RECEIVING YOUR CYLINDER - NOT FROM YOU POSTING IT TO US!

Once it has been carefully packaged and returned to you, all you have to do is bolt it back on your bike and away you go!


Please Note:

When you send your barrel to us, please ensure you enclose your personal details with it. This includes your name, return address, the model and year of manufacture of your bike and most importantly, a contact telephone number/email address.
