Engine Tuning/Maintenance
Maintenance
Here at Marshall's we have many years of Tuning 2 and 4 Stroke engines, one thing that is very important to keeping your motorcycle and engine running at peak performance is maintaining your engine. This requires just a little bit of time and will go a long way in keeping your engine running at optimum performance.
2 Stroke Engine /Chassis Maintenance
Cleaning your bike

First Step of any maintenance is starting off with a clean bike (making sure engine is really clean), You should always use a bike wash soap, Simple green works really well. Dry bike off and use WD 40 on chain and areas of bike that cloud rust. Warning do not put on brakes and disc.

Clean Air Filter

Clean Air Filter
A clean air filter is a key factor in keeping your engine running at optimum performance. A clean filter prevents dirt from getting into engine and causing wear to internal components. Always use a pour on type filter oil, (we do not recommend spray on type). Always use a Hi quality filter such as Twin Air or Maxima.

Top End Pre-Mix Lubricaction
Clean Air Filter
Keeping your engine oil clean on a regular basis will help improve engine life. On a 2 stroke engine the oil lubricates the clutch and transmission areas of the engine. A cleaner engine bottom end helps keep engine running cooler and longer. We recommend Maxima lubricants in all your motorcycle engine and chassis .
Ignition Cover Area

It is always a good choice to clean inside your ignition cover after every couple rides. Dirt does get into this area as well as condensation. Always clean with brake clean and if the cover is a plastic one its always a great idea to replace with a aftermarket aluminum one. This keeps stator area dry from dirt and possible rust.

This is the most important part of your 2 stroke edge is the Pre Mix. Most Top Engine builders recommend 32:1 ratio (4 OZ per US gallon). This is what lubricates your crankshaft bearings as well as your piston. Using a good quality oil is a must. Again we recommend Maxima Products. From 927 to K2 is a great starting point. Check with your engine builder for more info.

On a 4 Stroke engine your oil lubricates the whole engine, this makes it more important to keep it clean as it is whats protecting your engine. You should change this oil every couple rides and your filter every other oil change. On some four strokes there is a second filter to clean, always refer to your owners manual.
Valve clearance

Valve clearance
Your valves can really dictate what your engine is doing, I call it the vitals of your body. These should be checked every 10-15 hours of riding time. Proper clearance on most bike are .004-.006 on intake and .006-.009 on exhaust. Always refer to manual to check specs for your year and model.
