Re: DC System and sip speedo issues

You are simply suffering from low voltage... I dont like optimates... they eventually overcharge the battery.

Change the battery for a new one, run the scooter regularly and you shouldnt have any issues...

Re: Rapido Race 225 exhaust and gearing recommendations

4.8 final drive or there abouts should be perfect for those pipes....

Re: 60mm crank

If you dont change the rod length you may have the piston skirt hit the casing, and you need to trim it. Using a 110mm rod with your 60mm crank gives you lots more flexibility with tuning etc

Re: Action cams

I'm using a drift HD... only trouble with it is wind noise pick up from mic... wee bit of fur elastic banded over it eliminates that though...

Best results from a helmet mount vs a frame mount

Re: Leak down test spark plug

I'd try a new plug an crush the washer down to suit.

Failing that a little grease to try to create a seal...

But if its that bad i'd be looking to get the seat machined flat..

Re: High Revving - air leak - failed gasket

The marks on your piston tell me that you have had heat seize issues or stuck piston rings... you need to take the top end off and check these out...

Anything else is putting lipstick on a pig, IMHO

Re: High Revving - air leak - failed gasket

I would doubt whether a leaking exhaust gasket has caused that much damage.

I would suspect that you have bigger problems elsewhere.

You really need to strip to investigate. Are you in a local club? If not reach out to some of the local guys from the Falkirk Steeple etc to assist you

Re: ScootRS disc brake Caliper whats it off

Youre right, it was the CBR125, but cant remember what year...

careful buying one from a breaker though... lot of seized ones for sale
