I had to replace my K75s top triple clamp due to a broken bolt where it clamps the fork leg.

I sourced a replacement one online.  It was a bit grotty when it arrived so I thought I'd give it a clean before fitting it.

The result:
This forum is having a bad effect on me. Tripleclamp_zps4ccc1acc

To achieve this I separated all the bolts, washers, clamps and soaked everything in a bucket of Chemtech Blitz aluminium cleaner (200ml:3 litres water) for about 24 hours.  Then gave them a final wash in hot soapy water with a brush to get into the tricky bits.

Before I would have just bolted it on and said bugger it.  Now the triple clamp puts the rest of the bike to shame.

I'll be using this witches brew from now on.

Al

Looks like you've do a grand job. 


We don't seem to have that witches cocktail in old Blighty, and was wondering if you could give us a hint of the main ingredients so I could see if there is a similar brew to be had here.

Watch that stuff Shocked...it can set off a chain reaction, pretty soon it will have spread to the gearbox casing, then the final drive will start to shine.

Yes. I know what you mean !!!!

I removed the clutch to find the cause of a rattle.... (I think I've sorted that.. Thrust washer was knackered)

I'm now polishing the heads of bolts, painting battery trays, polishing exhaust headers, powder coating wheels etc. etc. etc.

Do you think this stuff would damage a throttle body? I got some here.

I'm pretty sure my R1100 TB repair kit is at the post office, I got a pickup card today. The TB itself is filthy.

Hi Postman, tried some stuff called Bar Keepers Friend--- IT WORKS. Cleaned last winters muck off forks and casings with no real effort. Its based on Oxalic acid and Citric acid. Web site is www.
kilrock.co.uk   I got mine from my local hardware stores £2.50. Don't use it on mirror finish, but it works well on the stippled casings and used well let down on stainless brake rotors:D

Whene I soaked the triple clamp, the shiny machined surfaces were still shiny machined surfaces, it did not eat into it it or degrade it in any way just removed the ingrained discolouring on the cast surfaces.  I dont think there would be a problem.

I have been using Blitz for a long time and I have found that you need to give it a really good scrub to clean the final application or it gets the white alloy bloom on it very easily.
I got put onto it by a customer that used it to clean the alloy bull bar and mudguards on his truck.

To clean a throttle body I use the carbie and injector cleaner, I don't know what is in it but it gets rid of the varnish build ups in no time flat.

I just used it on the outside. Put it on with a toothbush. Took 3 goes and left it on for 10minutes each time but it got the filth off. 
Check the state of the bypass screw Very Happy
