Weird (historic) MOT fail
Discussion
Just checking the MOT history of a bike I'm looking at and in 2010 it had a weird fail, immediately rectified and 12 years ago so not putting me off, but trying to understand what it means.
Rear Locking device(s) not correctly fitted which may make the motor bicycle dangerous to ride (6.2.1h).
All the MOT fail lists I've seen stop at 6.2.1e and I'm not sure what the rear locking device is. Does it mean brakes? Does it mean a chain/disk lock was dangling off in a silly place?

Only thing that springs to mind could be the locking mechanism for the seat? My mums 2014 ER6-F has a lock to remove the pillion part of the rear seat then the riders part just comes out with no additional clip or anything, it's just held in place by the latched pillion part. If that lock was faulty, I can see it being a fail because it's possible the seat could dislodge and fly off while riding.

05 ZX6R, I'm not aware of any weird mechanisms on it.
Assuming it was something silly.. although I'm not sure how a chain/disc lock could even be stored on the rear end. Swingarm looks tightly wrapped around wheel. Underseat exhaust so wouldn't want to hang anything there.
I used to have an 05 ZX6R. I do reckon it's the split pin.Assuming it was something silly.. although I'm not sure how a chain/disc lock could even be stored on the rear end. Swingarm looks tightly wrapped around wheel. Underseat exhaust so wouldn't want to hang anything there.
They are awesome bikes. But. Be very careful if it has an aftermarket exhaust fitted I had a nightmare with my, as the fitting of aftermarket exhausts tend to require removal of the heat shields. Which cooks the ECU in the tail. Would run perfectly for 40 minutes then become unrideable. Which reminds me I should update my thread on it. Internet hearsay suggest the 06 model has better protection but I don't know whether that is true.

A solution I've seen for VFR regulators that often suffer from being cooked is to fit a CPU fan off a PC, that's wired to an ignition switchable supply. May work here and is cheap/easy assuming there's space.
That's a daft solution ,as you are adding another electrical load. The regs failing is solved by finding the corroded connection and fitting a electrex reg that goes direct to battery.

It has a Yoshimura and I've heard of this cooking issue/06 being better. Will have a look at the installation and think about what can be done.They are awesome bikes. But.

12v fan might work depending on airflow.
The extra current draw does not even remotely add as much heat as a fan removes, otherwise power supplies in general wouldn't be fitted with them would they..

Whatever you're attaching it to on a motorbike should already be able to handle its own cooling but some things through poor design/location or changes to other parts may suffer from overheating (such as the CPU mentioned here and the VFR - and some other Hondas- rectifier.) The fan is only there to help ensure good air movement.
It's cheap and easy to fit. It costs peanuts and may allow the avoidance of breakdowns and issues. I've seen it fitted to bikes that did suffer issues but don't afterwards. Your choice if you try it or not but keep the reasoning real please!

The issue is not *enough* load. The reg/rec generates heat when it's "regulating", the less regulating it needs to do, the cooler it runs.
All SCR based reg/recs will fail eventually, it's just a matter of time before the heat cooks them (and not helped by the location on the VFR, it gets toasty thanks to the rear cylinders). The MOSFET based ones are better as they don't generate as much heat but certainly on my VFR it's tricky to find the room for one.

I had the same on a Thundercat i questioned it and he said there wasn't enough threads showing on the rear wheel spindle after the nut was done up. I put a thinner washer in and he then passed it.Rear Locking device(s) not correctly fitted which may make the motor bicycle dangerous to ride (6.2.1h).
