Anyone had issues with header tanks leaking ? Mine got warm yesterday and was bubbling around the fixing nuts

I know it's a issue on the v1/v2 phase 1 type , but not on the later classics .

Doesn't mean it's not faulty though , just not a common problem .

Have you checked the cap spring/seal as it might be stuck .

Or the overflow blocked mabye ?

Will check overflow pipe mate just got loads rusty staining around top now lol

I got the same...I thought it was the cap leaking on mine

Got uprated cap
