Removing/replacing subframe. - SV650.org

Im about to replace the rusted mess of a subframe on my 99 sv650 naked with a decent one and just wondered if anyone has done this before and were there any problems i should look out for?

I did it with no problems although I would suggest that you get the replacement powdercoated before fitting as it'll last much longer and shouldn't cost to much. The other thing I did was took some pictures of where the wiring went etc so it would go back the same

oh and i also replaced the normal bolts etc with stainless steel ones

IIRC its pretty straightforward, just make sure you remember the routing for all the wiring, brake hose etc. Might help to take a photo once youve removed the plastics.

why do i type so slow? lol. I also went powder coat + stainess fasteners. I kept the standard M10 subframe bolts tho, didnt fancy changing them for a different material.

If you do replace those M10, measure pitch. They are fine thread, not standard coarse thread.

I left those ones as standard, wasn't sure if they werehigh tensile or something. Didn't want the subframe falling off with my fat **** on it!

Just had mine powder coated, and i am not sure if it's the coating process, or some rough handling, but it didn't line up when it came to refitting, but just fit 2 of the 4 bolts, and it's easy to twist back into shape. Same would apply if you have a slightly bent one.

Oh and you will need to tap out and clean the threads up, even if they used bungs.

I didn't go the powder coating route but used some black hammerite on my sub-frames . . seems to do the trick

But pretty straightforward process taking them off
