Re: Wheels could not be removed

It's less to do with salt and cr@p and drainage.
It's a chemical reaction between steel and certain alloy'd metals. Steel on steel don't suffer the same problem.
Any metalergists who can give us the technical?
I did oxide and carbon systems but didn't cover metal alloys at Uni.

Re: Wheels could not be removed

That'll work as well!
Sometimes wonder if a sheet of cling film would work just as well!

Re: Wheels could not be removed

sorry mate but that's fairly standard when you mix steel and alloys.
baulk of timber and a sledgehammer is the only way to go.
might be worth a quick spray of WD-40 (other release agents are available) before reassembly so should be easier next time.
probably not what you want to hear!

Re: Brake Front disc’s

It doesn't sound too unreasonable.
Only got 21k on my 110 so not at that point.
My old C3. HDI seemed to need new rotors at around 40k and pads at 25k.
Guess it depends how often you use the brakes🤡

Re: 110 owners

Misfire or hesitation? Going off throttle to on throttle? Might just be a fuelling issue. For some reason people expect perfect fuel and throttle response in all conditions. Example: Suzuki SV 1000. Lovely motorbike, twist the grip nothing happens then it suddenly it dumps a load of fuel in and off ...

Re: Is 95 Celsius (203 F) water temperature normal?

As a closed pressure system the boiling point will be significantly above 100 deg.C (105deg.C?) so even 98 deg. Is a long way from being a problem. The thermostat and the temp sensor are mass produced I wouldn't be suprised if they are spec'd at +/- 5 deg. (+/-5%) and the opening and closing temp wi...

Re: 110 owners

Which may of course be programmed in so that the oil pressure has come up before the turbo runs up. No oil = detonation.
Turbo runs on a film of oil not a traditional bearing.

Re: 110 owners

Could I respectfully suggest that when cold the ECU is running the fuel injection rich (choke) this could be enough to overfuel on acceleration and reduce the turbo until all the sensors are with-in parameter. And external air temperature and density have a significant impact. One of the first thing...

Re: Engine noisy? Petrol 1.2 (82) 2016 model.

It's a 3cylinder engine. The off beat or growl is typical of the firing cycle of a triple.
Triumph motorcycles are good examples of triples.
Half of a BMW straight 6. Half of a flat 6 Porsche boxer.
Be happy its different!👍
