| Post subject: | fork emulators |
Can you guys clarify for me what the PVC spacers do? Just so i can clarify in my brain what i am attempting to accomplish while i am working. And is there any better way to modify the holes that need to be drilled on the bottom besides welding them closed? Can they be JB welded or bolted? The directions are VAGUE!!!!!  Finally got my bike out for a ride last weekend for about 50 miles with NO issues!! rode to a vintage swap meet and was famous as i rode in!!!!  Thanks!! |

I've used high-temp acid-core solder to plug the holes. You only need a propane torch to do it. I suppose you could drill and tap the holes and put a set screw in the hole, but that's doing things the hard way. JBWeld might work... Lane |

The spacers are to adjust spring preload, if that's needed. |

Take a look at the text I have highlighted in this document from Race Tech: https://dl.dropboxusercontent.com/u/399336/Pictures/Posted/Emulator_Fitting_Requirements.pdf Based on this I decided to modify my piston rods as shown in the following picture.  The instructions I received called out for 6 ea. dia. 6.35mm (1/4’’) holes which is a total area of 190mm^2. Instead I decided to just add a second set of holes just above the existing ones which means I have 8 ea. dia. 5.5mm holes, also with a total area of 190mm^2. Obviously, this doesn’t weaken the rods and I didn't have to weld or braze. PK |

Thats funny. Most comon line of thought is that stock forks of triples are underdamped. To increase compression damping, two of the four holes at the bottom should be closed to get some compression damping. And from the two 2 mm holes which gouvern rebound, one gets closed and the other one reduced to 1.5 mm. The reason why racetech suggests to enlarge to lower holes is to prevent disturbing their alternate system fitted higher up. |

Maybe it's just me - but over the years with all my bikes I've had good luck just varying the oils and/or amounts - little more/little less. |

I'm not going to argue with the experts here, but I thought the whole idea behind the Gold Valve was to replace the stock compression damping with a more sophisticated system. So, instead of squeezing oil through holes you are squeezing oil through an adjustable spring loaded valve. |
