GSX750F banging noise?

[MSTRS:Me]

Machining is not an option (will go below minimum thickness before the warp is removed)
If it's just drag, then remove the calipers, pop the pistons out, clean everything, fit new seals, reassemble, new fluid and bleed. Recommend this.
Or put new pads in...sometimes the bores in the calipers get a bit 'weathered' towards their outer limits for piston travel, causing them to stick. The new pads are so much thicker, that the pistons are back in a clean part of the bore.

Thanks for the great advice (as usual!)

I'll pull the buggers apart, clean them up and do the fluid.

I'm really enjoying working on this bike, learning a lot!

Just took her for a spin over the hills and back through sumner then town.
I took it easy but she went bloody well!

Good to hear it is all up and running....
Now all going well, you won't have to pull all the plastic off again for ages.....

[sammcj]

Think again, new front visor coming next week!

arghh.....

Oh, man... I feel for you.
I did heaps of miles on my 1997 600 Teapot, and hardly ever pulled it to pieces.

I did have to pull it completely apart after one of the Brass Monkey Missions, and Oh boy, what a mare!
Once I was going to take out the little fan that used to stay on after the key was turned off (Californian Model), but couldn't ever be bothered pulling it to bits again.

To be fair, i was using it to commute from Auckland to Bulls, so didn't really want to spend time with it in pieces (it was only 3 years old at the time).
Did well that bike to be fair. Everything I asked of it. Just a little under powered, and a little too heave for a 600... So got my current CBR to replace it.

No bad memories with that bike, so long as I rode it within the envolope.
Never had any reliability issues... once i replaced the stuffed battery....

That's really reassuring to hear, I'm glad I made a wise purchase, even if I am going to get called a teapot rider from time to time

Could be way worse

[sammcj]

Indeed.
I'm doing my first ever long trip next month.
Christchurch to Oturehua, Then 3 days later: Back to Christchurch

Way Cool!
You are making me miss the Mainland now! (Was from Ashburton myself)

There are some really neat roads around there.......
Have a great trip....
Oh, best thing about GSX's... SACS!
No need to worry if your radiator fluid is going to freeze over night! Especially handy if you are at Iderburn Dam on Queens Birthday weekend.
Got to love Oil Cooled motors for that.

[sammcj]

Oh I didn't realise they employed SACS tech, rad.

My old man has the tavern there so hopefully I'll park her up in the garage anyway

Yes your bikes based off the 1st generation long stroke gsxr 750 oil boiler (SACS) engines. Very few differences internally, and identical externally except cable clutch I believe possibly.

If you want reference for what bad noises are from these engines i've got a couple of video clips. One from my gsxr 750 when it bent a conrod (no vacuum petcock + leaking carbs = fail bigtime) and one of a 1100 with stuffed output bearing (fairly common failure for these 750/1100's not that much fails on these engines when cared for really).

They use them in 3/4 midget sprintcar races, with only 2nd/3rd in them and rev the nuts off them so they must be pretty strong Enjoy the bike, it should be really good to you

[sammcj]

Thanks for that fruitloops!
Yeah I actually had a stripped sump bung which I got a decent fellow over in woolstown to repair, he rebuilds the 750 engines to put in those very stock cars!
The bike is going sweet now

[FruitLooPs]

Yeah Glen Durie re conditioners huh, seems to be a great guy. he pulled my engine apart and crack tested stuff when I bent the conrod. Reassembled it myself though. Sold him an engine too, mean to be a 13:1 high comp ex-racebike engine from a guy in the USA when it arrived it was stock as a rock, pretty pissed I was..

[sammcj]

Yeah thats the guy - top bloke!
