DIO Piston Install TIPS
These are some tips on installing or taking off your two stroke pistons from the crankshaft. Always keep the parts clean and take your time and do the job right. Remember that the piston always goes on with the arrow on the piston crown, pointed towards the Exhaust port. Put your rings back on or take them off with a piston ring expander. Rings are very brittle and can snap in half, very easily. Line the rings up with the single ring pin in each slot. Oil the rings and cylinder walls with two stroker oil and carefully lower the cylinder onto the piston. Use a new base gasket , scraping off the old one. When changing or working with the cylinder off, stuff the crankcase around the crank rod to stop foreign debris from entering and fallin in the crank well. Use a new head gasket every time and torque the head bolts in a cross-hatch pattern to avoid warping the aluminum head. Take your spark plug and screw it into the head before installing to make sure the plug sits flush with the top of the cylinder head chamber.

how to install motorcycle crank bearings
never hit the bearings, even if you use a block of wood with it or a rubber mallet, these cases are designed very precise for this, If you do this job I recomend using an oven or a propane grill (top rack only) to heat these cases. Also since you shouldnt put an open flame on your new bearing stick the crank in the freezer that will cause the crank to shrink ever so slightly and it will slide into the WARM bearings. Sounds crazy but if your crank doesnt spin right or you have premature bearing failure, you will relize why this is done. Yes you can use open flame on the cases if you prefer but dont use it on the bearings. Make sure you remove the seals before you do this too.

Yamaha YZF R1 crossplane crankshaft technology explained
The crossplane or cross-plane is a crankshaft design for V8 engines with a 90° angle between the cylinder banks. The crossplane crankshaft is the configuration used in most V8 road cars.3d model of a cross-plane crankshaft demonstrating the 90 degree angle between the crank throws and the large counter weights.The crossplane crankshaft has four crankpins, each offset at 90° from the adjacent crankpins. The first and last of the four crank pins are at 180° with respect to each other as are the second and third, with each pair at 90° to the other, so that viewed from the end the crankshaft forms a cross. The crankpins are therefore in two planes crossed at 90°, hence the name crossplane. A crossplane crank may have up to five main bearings, and usually does, as well as large balancing weights. Crossplane V8 engines have uneven firing patterns within each cylinder bank, producing a distinctive burble in the Exhaust note, but an even firing pattern overall. Their second-order balance, owing to the 90° bank angle and 90° throws, means no additional balance shaft is necessary to achieve greater smoothness. Without the 90° bank angle, a balance shaft may be required. The other prominent design for a V8 crankshaft is the flatplane crankshaft, with all crankpins in the same plane and the only offset 180°. Early V8 engines, modern racing engines and some others used or use the flatplane crankshaft, which is similar to that used in a straight four or flat-four engine. Flatplane V8 engines may use any angle between the cylinder banks, with 60° and 90° the most common. They lack the V8 burble and the superior mechanical balance of the crossplane design, but do not require the large crankshaft balancing weights. Inherent balance of the big ends is like a straight four, and modern designs often incorporate a balance shaft for smoothness. But without balance shafts, flatplane designs have the least flywheel effect of any V8s, which allows them to be more free-revving. The crossplane design was first proposed in 1915, and developed by Cadillac and Peerless, both of whom produced flatplane V8s before introducing the crossplane design. Cadillac introduced the first crossplane in 1923, with Peerless following in 1924. Inline-4 engines can also use the crossplane concept. The 2009 Yamaha YZF-R1 motorcycle uses the crossplane crankshaft and, in the absence of the 90° bank angle of the V8, must use a separate balance shaft geared off the crankshaft to eliminate the inherent vibration (a primary rocking couple) found in this type of crank. A crossplane crank has been used in Yamaha's M1 MotoGP racing models in the past. Yamaha claims advances in metal forging technologies make this a practical consumer product.

Connecting Rod Bearing Failure - 1997 Honda Civic
1997 Honda Civic, with a SOHC VTec 1.6 LT Engine, has a bad connecting rod on the #4 Cylinder. This video shows the basic steps I perform to confirm which cylinder was effected and the sound that is made when you have a bad Rod Bearing. (In this case the issue was caused by a bad head gasket, which was leaking internally between the Oil and Water Jackets. Unfortuatly issues like this are not usually detectable untill it is too late, unless you have your oil tested to determine if it has glycol in it.)





Crankshaft Refurbishing
Many of you have seen this one before. I apologize if bringing it back offends anyone. Domestickilla gave me a crankshaft, and it's a nice one that I want to clean up and use again. You'll be seeing a lot of it and because of this, this video deserves to be here. I fixed what I broke, and this was my experience. In this video Ballos Precision Machine demonstrates magnetic dye penetrant testing, crankshaft polishing and inspecting the balance of a "butchered" 4g63 6-bolt crankshaft.
