Fitting Instructions

 

  • Slide the rubber boot down and disassemble the throttle housing, remove the old throttle tube taking care not to damage the throttle cables.
  • Carefully remove grip from the old throttle tube if required.
  • Inspect the cables and housing for excess damage or wear, clean and lube them or replace if required.
  • Clean the handlebar and inspect for damage where the old throttle tube has been spinning on the bar if a ridge is present replace the handlebars.
  • Slide the new throttle tube on the handlebar and lube using a penetrating lubricant preferably Maxima MPPL (do not use grease as this attracts dirt and makes the throttle stick after a short period of time).
  • Re-assemble the throttle cables and housing again using some penetrating lubricant.
  • Tighten the throttle housing in the correct position on the handlebars.
  • Adjust the cable to the required (free play amount) of your liking.
  • Rotate the handlebars to their maximum position to check proper operation of the throttle and correct cable routing, some re-adjustment of the cable may be required.
  • Slide the rubber boot back over the housing.
  • Cover the hole in the end of the grip with some electrical tape (To stop glue entering the throttle barrel) and apply a small amount of RFX grip glue to the outer end of the throttle tube on the outside diameter.
  • Apply a small amount of RFX grip glue to the inside of the new grip and slide onto the tube.
  • Twist the grip to the correct position and leave to dry.
  • Apply RFX safety grip wire if needed.
  • After the glue has dried again check proper operation of the throttle.

A Great Buy - But Might Be Too Long
Special Size: Low Stretch, Size: 34W x 32L, Color: Dark Midnight Wash
These jeans are an excellent buy! I have only bought Eddie Bauer jeans for the last 25 years, but this time I couldn't find my size in the correct style. I prefer classic/relaxed in dark blue. I don't like the "pre-washed" or worn look. The Dark Midnight Wash was exactly what I wanted - new jeans. The waist measurement was perfect. Unfortunately, the 32 length was waaay too long. (All the Eddie Bauers were 34x32). So I just did an exchange for a 34x30, which should be good. Eventhough the length was too long, I'm still giving 5 stars. Different manufacturers cut sizes differently. It is what it is. And the return process was EZ and the replacement size was in stock. Seriously, there is really no quality difference between these Amazon Essential jeans and my old $60 E.B.s No one sees the label anyway!

Weird sizing, snug in some places and much more “relaxed” in others
Special Size: Rigid, Size: 33W x 28L, Color: Black
Comfortable and close fit around waist, buttocks, crotch - but from thigh down trouser cuff it’s a VERY relaxed fit, much bigger than I need even with thick muscular legs. Not quite clown pants or bell bottoms, but a still a strange look. I’ll probably be sending them back.
