Suitable Replacement Stihl 090 G Piston & Cylinder Kits
Performance Parts Supply Pistons & Cylinder Kits meet or exceed OEM specifications for Stihl 090 G chainsaws and they cost less than OEM filters while maintaining excellent quality and durability. Pistons & Cylinders should either be replaced or honed per manufacturers specifications that are located in your owners manual. You can quickly buy our suitable replacement Stihl 090 G Pistons and Cylinder Kits for sale in our online store and get it shipped fast.
The two cycle oil should be a JASCO
rated oil (FB, FC or FD). The oil has only one chance to properly
lubricate the piston, rings and cylinder before being burned off
during combustion. Oil is critical to operation of the two-cycle
engine. If the oil is mixed too rich, you can cause carbon build up
on the piston, cylinder head combustion area or behind the rings.
This buildup can cause the rings to stick and will result in poor
engine performance. Also, the use of stale fuel will cause cylinder
and piston damage to your saw by causing ring sticking, poor
lubrication and spark knock (pre-detonation). Pre-detonation in a
chain saw engine will destroy the piston in a short period of time
and usually results from low octane or old stale premixed fuel. We
recommend using gasoline that is 90 octane or higher in your saw once you have installed your new Stihl 090 G Piston & Cylinder Kits. You should
also shake your chain saw's mixed gas before refueling your chain
saw. Another proven tip is to give the saw a good shake before
staring it to ensure fuel and oil is mixed properly. The gas should
be fresh (not older than 60 days) and stored in an air tight
A properly adjusted carburetor along
with the proper gasoline/two cycle mix will help cool the engine. A
lean running two cycle engine will overheat causing Stihl 090 G piston and
cylinder damage. Also, an air leak will cause an engine to run
extremely hot and will almost certainly cause extreme damage to the
piston and cylinder.
Performance Saw Supply pistons and

Specifications of Performance Saw and
Supply pistons and cylinders:
1- Material - The factories use the
highest grade material which comes from Japan. The material is called
2- Casting - Before coating, all
Performance Saw Supply cylinders are put through 13 preliminary tests
to ensure proper tolerance. The cylinders are then coated to ensure
maximum penetration, thickness and coverage. Coating thickness is
.04-.063 mm of chrome which increases the life of the cylinder.
Certain cylinders are NiSi [Nikasil] plated which wears extremely
well in two cycle engines.
3- Machining - Complete machining
of all cylinders is performed by accurate CNC tool machines.
4- Die-Casting - All cylinders are
made by slow gravity fed Die-casting. This increases the weight of
the cylinder which enhances the performance and life of the rebuild.
5- Toolings - Each cylinder tooling
has limited life and is replaced after the manufacturing of 50,000
pieces. All tooling is checked on a monthly basis.
6- Quality Control - Special
inspection is done on every cylinder inlet and exhaust port which
includes chamfering of all burrs. Every 20th cylinder that comes off
of the production line is thoroughly inspected for accurate
tolerances. Performance Saw Supply cylinders and pistons are
manufactured by factories that have over 30 years experience in the
piston and cylinder industry. These factories provide OEM cylinders
and pistons to saw manufacturers in Western Europe and China. The
factories also provide OEM cylinders and pistons to a major American
Note: We recommend using a piston ring
compressor kit when rebuilding 2-cycle equipment to ensure
Note: Some cylinders may only need
honing to clean up the cylinder bore and a new piston and ring
assembly instead of a cylinder assembly.
Note: Nisi[Nikasil] cylinders can not
not be honed or cleaned up using sand paper. Nikasil coating
penetrates into the aluminum [Liquid Nickel and Silicone] and the
hone will remove the coating process exposing bare aluminum.
