Exhaust Studs

[Dead Eye]

Haven't heard anything from the garage yet but going to give them a call tomorrow as I was hoping to have heard something by now - plus my car is booked in this Thursday so I will be otherwise vehicle-less if I don't get it back...

[Exupnut]

i could get mr vfr to av a werd. he's used him for years. if all else fails we could garotte/hang draw quarter/kneecap/behead or  :2guns  him into admitting it was all his suppliers fault :lol

IT LIVES!!!

The Fazer is back at home with some nice shiny new BT023's and discs that don't judder the crap out of me when braking

So, time to bed the pads into the discs and scrub in the tyres a bit more Looking forward to Sunday a lot more now

YAY!!! Awesome news buddy!! Now take it easy out there!  8)

we've been having fun today, got all the nuts off though..

[Dead Eye]

Looks like you are having as much fun as I did when this all began... Thankfully that sort of drama wasn't required, the buggers just fell off so damn easily - the metal studs had obviously warped and the material had become useless

[Tilts]

studs seem ok, we just used the dremell to cut groves into manky nuts, plenty of gt85, old screwdriver and copper hammer, and tapped them loose, took all afternoon, but all nuts off, now we need to try and get the headers out of the head without damaging the head...  going to take mine off and replace.with decent stainless nuts, before they start to corrode.

[His Dudeness]

anyone tried a nut splitter on the exhaust nuts? might save a bit of hassle

[Andy Smith FZS]

Nut splitter, bought one...  Didnt use it.  Wouldn't really be enough room to use it anyways.

Imperial sockets have a purpose after all... whacked one on with a hammer and it worked on a couple before I ruined the socket. (3 dodgy nuts)

Cutting a groove in the nut then tapping it round with a hammer and a screwdriver does the job if other attempts fail, just had to do this with one of the screws on my front brake res as I butchered the head on it. 

[Dave48]

Andy-had same prob with front master cylinder reservoir screws recently. I use small then progressively larger size drill bits to remove screw head then remove cover & get molegrips on shank of screw. :eek Never failed yet.  :lol Mine had been overtightened & corroded in.

[Andy Smith FZS]

Dave 48 - any idea what size of screw I'll need to replace it?

Had a trip to toolstation yesterday to buy some nuts for putting the new downpipes on, not sure if they would sell suitable screws.
Dont really want a pack of 1000 either!

[Dave48]

Andy- the Yamaha part no is 98707041200--cost from local dealer £1-12 for 2x They are fine thread and the screw heads are designed to fit flush with top cover.

[Gingernutz]

Was just contemplating doing this job- replacing the down pipes myself- think I will let the garage do it having read this thread. As a mater of interest, if the engine has done 85k and you are removing it to get the studs out why not just get a replacement low mileage engine?

[Dead Eye]

Because a replacement low-mileage engine costs £250-350 and removing the studs cost me £40

Besides, I have a second low-ish mileage (24k) engine that I am rebuilding at the moment which will go in once its done

[yamy]

What size drill and what size easy out would i need
as the fourth one from the left as snapped off at the
engine head ?


Cheers lads

[Dead Eye]

As far as drill bits go, I would suggest nothing larger than 5mm - start small and work your way up if this is the route you want to take. Not sure on the easy outs as I haven't used them before - as noted at the beginning of this thread, I removed the engine and had a local machine shop remove the studs for me

[yamy]

Sure as hell can't make it any worse  :rollin

[His Dudeness]

stay away from easy outs. if you snap one of them in the engine you'll never get it out

[yamy]

with that said I've decided to drill it out and re tap it out
and hope for the best
