Shite quality disc bolts

[Rexr]

Well there's one thing u can rely on with Yamaha and that's their shite quality standard disc bolts, I think their made of fecking cheese and why use different ones on the back (in fact beefier ones on the back) where's the fecking sense, I can see the drills coming out this week, if the heat and torx bits don't work........rant over for now lol ggggrrrrrr.........

So is it worth attempting to take mine out,57 plate FZ1s , to refit then and know they will move ????

Yes. But don't try it without an impact bolt. Probably worth replacing them with titanium whilst you're at it - about £35 a full set off eBay!

OK, there's a challenge, oh and any reccomendations on refitting, i.e ,,dry..with grease,,threadlock , paint ?

If you do get titanium, i'd definitely recommend some copper grease, otherwise they will dry weld themselves to your wheel, and you'll never get the bastards out. Just a little bit, and make sure if you torque them up you drop about 30% off the torque value to account for the grease!


Then just check them every now and again - I've never had any come loose due to the above, but better late than sorry!

You should use a semi permanent thread lock when fitting disc bolts, not copper grease. If you buy new Yamaha ones you will see some blue stuff in the threads, I can't remember the loctite equivalent off the top of my head.

And that's the stuff that locks down hard over time and makes them a right bugger to get out!

I've spent the last 2 weekends stripping, polishing and painting my wheels on my gen 1. Surprisingly I didn't get any real problems removing the disc bolts; I was obviously lucky...

I have replaced them however with Stainless bolts from Ebay knowing I'd get issues with the old cheese bolts in the future!

Getting new tyres fitted this afternoon and I can't wait to get the wheels back on the bike later... :-)

Well with a bit of heat they came out very easy (bang in a torx bit take it back out and heat the bolt up for about 30 seconds and insert the torx bit and undo.... )

The front and rears come out easy with a bit of heat and an impact wrench, you need that to break/soften the loctite.
