I recently went through this when looking for stainless bolts.

For steel bolts this is typically quoted as 4.4, 8.8, 10.9 or 12.9 etc.
For Stainless it seems to be 70, 80, 90.

80 is equivalent to 8.8 as its tension strength is 800 MPa.

For my front mud guard mounts I just used A2 70 and they've been fine.

I've just recommissioned Wendy's track Street Triple and putting it back to road spec. Not exactly a polisher as it's been down the track a couple of times but now ready for its MOT next week and is an amazing fun bike. Also recently acquired another Gen1 Tuono without MOT it failed on front discs and had and electrical issue with the light switch. Also the tyres were 10 years old. That's all sorted apart from discs which will be fitted at the weekend. That can then go off for it's MOT. Then the RD250 needs to come back apart to re fix half the stuff previously done as sitting around for a couple of years takes its toll on a 46 year old bike. Also need to balance the throttle bodies on my other Tuono which will hopefully cure it's poor cold starting. I think then a few will go up for sale to pay for something else.

I was surprised when I learnt that s/s is weaker than normal hi ten steel! Good tip that.

Now I have the time in retirement, I’m starting to recommission my Ducatis from being laid-up for so long. I only hope my old body can still bend enough to ride them! Look out for a tubby elderly bloke grimacing in pain on a bright red sports bike next year!!

Any problems Dave, this other greyone can help with riding the Dukes

Interesting; I knew that not all s/s was equal but not what the differences were. So what's the pro's and con's for each of these?

Just google: difference between A4 and A2 steel
Mainly, Corrosion resistance (against salt), yield & tensile strengths.

A4 is generally better than A2 in all respects, and therefore more expensive. It is worth noting that the best A4 are still not as strong as a standard 8.8 spec steel bolt. Stainless is fine for non-structural applications, but be wary for anything that is load bearing.

Additionally (sorry for late entry to this thread), beware Stainless-Stainless threaded joints (unlikely on a bike, but can happen elsewhere), especially if a high torque load is needed (if properly designed, at least one side would not deploy Stainless) - stainless threads are prone to galling if an anti-gall paste isn't used, and when that happens it may as well be welded together because it'll never separate.

I took a chance on cheap Busa coils from AliExpress. At last I had a chance to take it for a spin today. With new plugs and the air filter cleaned it all works fine again. No idea how long the Chinese pattern coils will last but the cost of OEM is horrendous.

Glad you got it back on the road cost effectively

Where did you look for the OEM ones?

Suzuki UK are taking the piss with pricing so I'll now use Webike Japan for any OEM parts.

After a lengthy front end overhaul my trusty old Sprint ST has just whizzed through it's MOT. Still to do is fitting a new-to-me rear shock, a de-catted under seat silencer plus accompanying Tunecu upgrade, new n/s rear flasher pod and a strip and service of the rear hub and linkage, also all the other ongoing odds 'n sods that goes with running a well used 18 year old bike. So see y'all early (I hope) in the new year.

Richard, Webike are still very pricey. The best price I found for OEM part number is (courtesy of John - kata) from:-

Set of four coils from China less than £30.

Famous last words. Pulled out the sump plug on the Benelli to find a stray gear tooth stuck to the magnet. Striped out the clutch to find the culprit.



Now starts the search for suitable parts.

Looks nasty Jason. I bet Benelli gears are cheaper than official Suzuki stick coils.

Well i'm going to be taking the wheels off the FJR and get then sprayed/powder coated.
Also i'm think of getting a sublime wrap from the track bike.....just wondering what style to go for now.....
