Avail Motorsports has worked hard to put countless hours of testing and years of development on the track with the help of DH1Mods to bring you the best performing cylinder head on the market. Whether you're a back yard rider or a national competitor, this is the solution you're looking for to wake up that bike of yours. 

Your cylinder head must be OEM and UNPORTED.  

Once you check out, we will email you a shipping label to get your cylinder head to us.  We will strip it down, have the CNC porting completed, and email you with any recommendations such as new valves, new valve seals, HD valve springs, etc. Your head will also be cleaned and vapor blasted before it is returned to you. We can install any of those items before shipping the head back to you!  You can also add any items you would like installed to your purchase and leave a note on checkout requesting them to be installed or sent back with the cylinder head.   

Turnaround time is typically 5-7 business days but can be longer during peak season.
