Replacing Ignition Wires in Stock Coils

Submitted by xjcdadmin on Sat, 10/27/2012 - 18:05

This is the 5th set of Yamaha coils (4 XJ sets and this MaximX set) I have repaired this way. I have tested a set (engine running) with the full force of a pressure washer. I highly recommend this to anyone who is having problems in wet weather. Net cost is about CDN$10 per set -- 30 if you buy new NGK resistor caps too. Compare that to the cost of a new set of coils!

Turbo Oil Leak sources

Submitted by Dave Jackson on Sat, 07/31/2010 - 04:24 
Hi all

Anyone in need of the main shaft seal for a Seca Turbo oil pump -

The seal is not listed by Yamaha as they only ever sold complete pumps which 
are now obsolete.

I have managed to track down what appears to be an identical seal as used in 
many Honda model oil pumps including the GL1800 Gold Wing.

The Honda part number is 91208-MN1-771 and the seal size is 11 x 15 x 3mm

If this seal has failed you will be getting oil flowing back to the turbo

Cylinder and Piston -- Inspection and Repair

Submitted by xjcdadmin on Fri, 07/02/2010 - 10:59

F. Cylinder

1.    Inspect the cylinder walls for scratches. If vertical scratches are evident, the cylinder wall should be rebored or the cylinder should be replaced.

2.   Measure cylinder wall wear as shown. If wear is excessive, compression pressure will decrease. Rebore the cylinder wall and replace the piston and piston rings. Cylinder wear should be measured at three depths with a cylinder bore gauge. (See illustration.)

Cam Chain Adjustment

Submitted by xjcdadmin on Fri, 06/18/2010 - 01:46

The cam chain becomes stretched with use, resulting in improper valve timing and engine noise. To prevent this, the cam chain ten-sioner must be adjusted regularly.

1.    Remove the timing plate cover.

2.    Slowly rotate the crankshaft counterclockwise until the "C" mark on the timing plate aligns with the stationary pointer.

Fuel Level Adjustment

1. Measure fuel level. Adjust if out of specification.

 

Measurement steps:

• Place the motorcycle on a level surface.
• Shim the center stand as required to level from side to side using a level across the carb bank

Chapter 1, GENERAL INFORMATION and SPECIAL TOOLS

Submitted by xjcdadmin on Tue, 06/08/2010 - 01:10

GENERAL INFORMATION

Introduced in 1985 the Maxim X resulted from a request of Yamaha USA for a "little brother" to the upcoming V-Max. Mother Yamaha already had the 750 Maxim and the 750 Virago, and plans for the new FZ750 (to replace the vernerable 750 Seca). They balked at building yet another unique engine in that class, so a compromise was struck: Yamaha would design the new FZ "Genisis" 5-valve motor to fit on a standard XJ transmission utlizing the strengthened gearset of the XJ900 and 650 Turbo models, and the MaximX was born.
