That Tom Cruise might have loved… or maybe not… Top Gun.
Haven’t seen the new one… or the old one either… sorry about that. <\/p>\n\n\n\n

Work is progressing smoothly. <\/p>\n\n\n\n\n\n\n\n

Since the mileage hasn’t increased much since last time, it’s better to do it as needed. <\/p>\n\n\n\n

Checked the antenna issue with the mysteriously discontinued Daytona radar.
The current installation should be fine. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The brake noise issue.
If you want the noise eliminated, I can pretty much eliminate it, but whether that condition persists depends on the owner.
I basically think it’s either a compatibility issue between the disc and pads, or hardening of the pad friction material surface.
So I’ll hone the disc
and peel off a layer of the pad surface. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The machining is on the right side. With honing marks like the right side, it will be reborn with that new-like “shoo-shoo” sound. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The pad contact is a bit subtle too.
The center doesn’t seem to be making contact at all. Once you smooth out the surface and repeat hard braking a few times, it should settle into a nice balance. <\/p>\n\n\n\n

The caliper condition is decent.
This is a Tokico 6P 90MM pitch, so in the future switching to a Nissin 4P 90MM would be even better. It should fit as is, probably. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Labeled both discs left and right with P-TOUCH.
P-TOUCH is more resistant to chemicals and solvents than Tepra, and no adhesive residue remains after peeling. <\/a>
Tepra leaves color 100% of the time… <\/p>\n\n\n\n

Cleaned and lubricated the chain and charged the battery. <\/p>\n\n\n\n

Also replaced the brake fluid. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The throttle cable was stiff, so I lubricated and adjusted it. <\/p>\n\n\n\n

The noise is completely gone and it should be running great now (*\u00b4\u03c9\uff40*) <\/p>\n","protected":false},"excerpt":{"rendered":"
