Piston / sleeve resizing
We take your worn out piston and sleeve with little or no compression and we clean and Resize the piston/sleeve. You will have restored compression with a top quality 3 stage "factory" taper. That will add gallons of life to your engine and restore lost power and tuneability. Our tooling is top quality in the industry and gives the best, most accurate results possible.

We resize .12 to .30 engines only.
Bearing replacement for most  .21 - .32 size engines...
Some engines model price may be higher for special size bearings ...

Ceramic bearing replacement which includes front and inner Ceramic  bearings
and installation.
Steel bearing replacement service, includes high quality steel front and rear bearings and installation.
Head button reconditioning
If your head button has heavy carbon buildup and minor damage or pitting due to detonation, we can recondition it and remove carbon and pitting.(carbon buildup can have an impact on your engines performance by raising compression)
Crankshaft  fill
Whether your crankshaft silicone has come loose, fell out, or if you are looking for the extra performance and want your crank filled we can do it! We use Oem Spec Silicone that provides great performance and longetivity.  The silicone creates a "ramp" to smooth and guide airflow to the ports creating more power and quicker revs. also reducing crankcase volume to better "charge" the combustion chamber.
This fill is only for engines that already have a void in the crank where no drilling is required

Crankshaft drill & fill
In this service we lighten and drill out the built in metal ramp in your crankshaft and fill it with OEM spec silicone filler. This reduces crankshaft weight by approx 10% meaning less rotating mass, quicker spool up time and higher revs. There is a reason why all the high end engines have it done. Now you can have it Done to any .12 to .32 crankshaft!
Business hours M-F 9 to 5 eastern time
Piston sleeve lapping
Piston sleeve lapping reduces break in time by approx 60% and reduces  stress on the engines crank and rod during the break in process  by  reducing the tightness of the piston/sleeve fit.   This is very helpful on very tight engines like Novarossi, Alpha , Arrow and other brands. It is  also helpful  for racers who do not have the time to waste with a very long break in.  (complete engine can be sent in or just piston/sleeve/rod)
