Motorcycle Repair: 89 FLH - ENGINE & TRANS ALIGNMENT, harley factory, rev tech

Question
HOW DO I ALIGN THE ENGINE OR BIKE TO RUN NEUTRAL/STRAIGHT AT LOW SPEEDS. I REPLACED THE ENGINE & TRANSMISSION CASE. THE BIKE PULLS TO THE LEFT WHEN I TURN TO THE RIGHT  AT VERY LOW SPEEDS. WHEN I AM RUNNING THE BIKE AT AVERAGE SPEED OR ABOVE 30MPH OR ABOVE NO PROBLEMS. WHEN THE BIKE IS ABOVE 2000RPM. I REPLACED THE UPPER & LOWER MOTOR MOUNTS WITH NEW ONES. THE BIKE RUNS STRAIGHT AT HIGH SPEED 50MPH PLUS. THE ENGINE IS A REV TECH 100CC. HOW CAN I STOP THE BIKE FROM PULLING TO THE RIGHT, HOW DO I ALIGN THE ENGINE/BIKE.

Answer
first you have to aline the rear wheel in the swingarm, If you look in the Harley Factory service manual they show you how to make a tool out of a long wire that goes into the swingarn piviot shaft and past the rear axle center, Use a small o-ring on the wire tool. axle center on both sides should be equal, the motor aliment you will need two 9 foot stright peaces of metal and bungy them to the front tire and the reat tire. the front tire should be with in .030" of equal of both sides. The factory service manual will explaine it much better then I   JOHNNY
