Yes, but technically i think they supplied ya with enough to possibly do both bikes should you have two and maybe rig up an extra clamp or two from the garage. Gonna get one myself when i have piss away $$. I, like you, enjoy trying to drop every ounce off my bike. Looking at your bike reminds me i need to wash mine! Love the tricky bits on that bike Pete!

The problem with HRC tubing is that it sweats brake fluid. It literally is semi-permeable tubing that lets the fluid seep out of microscopic pores in the tubing and it will continue to do so until it gets old and brittle and then doesn't work properly at all. Back when all the HRC bikes used it the first things a technician did when handling the bike would be to wipe the tubing with the rag they always had in their hands...

Most people don't realize it, but brake fluid reservoirs are vented which is how they get moisture into the hygroscopic brake fluid which in turn requires the fluid to be changed at regular intervals to retain its effectiveness. The water absorbed into the fluid can be turned into vapor with excessive heat and then you get the dreaded brake fade we have all experienced. When you use a kit like that with a solid plug it can create pressure issues and improper operation of the braking system if not maintained attentively. Granted the rear is generally used a lot less than the front, but it can certainly happen.

Tygon tubing is a much better choice for that type of reservoir.

I actually new the oem was vented LDH and when it arrived I thought it might have a tiny pin hole but no it's solid!I thought it was Tygon tubing that's why I purchased it but I will check that out!and Captncalyx I already have cut 35mm of that long mofo already lol!and thanks for the compliment also

Hmmm i hadnt looked closely enough at HRC's package apparently and assumed it was Tygon. At any rate im hunting down tygon when the time comes no matter who it comes from. So the HRC kit on Ebay is NOT tygon?? Hmph!

Edit - nice tip on venting the plug.

been there done that, the Honda tubing part number 43503-nx4-000 in the "kits", sweats, and is worthless.

as or10r stated, contact kurveygirl, and get REAL TYGON TUBING.

you can use it for the reservoir mod, and for replacing the tubing from the front master, to the reservoir as well. I keep several feet of both sizes on hand, in clear, for just such an emergency. :D Ski
