K3 Removing Rear Sub Frame
 

The rear sub frame on my K3 is begining to go rusty, so I want to remove it to strip it and re-paint it. Is this a major job? What problems should I look out for and will I need any specialist tools?

Last of all, how long will it take roughly to remove.

Thanks.
Tim.

I would strip the plastics off and repair it in place as there is a lot involved in taking the subframe off.

Pretty easy, if it helps take a few pics once the bodywork is removed that you can use for reference when you put it back together.

Dont forget the tip over sensor has a right way up and a wrong way up (there is an arrow on it that should point upwards. Its a small matchbox sized black thing just in front of the battery box. If you dont have the right way up the bike will not start :-)

Also, be gentle if you decide to remove any of the wiring loom connectors, especially to the ecu.

To remove, if you've never done this before, allow 1-2 hours. The process is roughly:
- remove side covers and seat
- pop plastic rivets along the rear bodywork and remove the four retaining bolts under the seats.
- remove the grab rail
- unhook rear seat release cable from the seat locking mechanism
- lift off rear plastics
- release electrical cable ties and unhook fuses etc.
- Disconnect and remove battery
- unbolt battery box / undertray plastics and remove
- undo four bolts that hold the subframe on, and lift away.
- careful not to snag on the electrics.

Thanks for the tips. I also have a aseries 4 alarm to contend with.

It's pretty simple to get off. Don't bother painting it though, you'll just end up painting it again next year. Get it powdercoated. That's what I plan to do this winter :)

My K3 subframe is away getting powdercoated the noo. P/coat is a better than factory finish compared to paint.

My tip is to get some different colours of electrical tape and colour code all the connectors (for there are many) you undo. A lot easier when you route the loom back in and re-assemble,( in my case months later!)
