HI, I'm 90% through the install of the TEC Centre STand for my 2021 Triumph T100. Got it fitted, and the spring in place. No problem so far. Do you think I can fit the rubber bung that fits in the hole at the base of the LHS Exhaust? Anyone have any ideas how to fit a big rubber bung into a little hole? Tried Grease, washing up liquid, silicone grease, silicone Spray and even spit. Cant get the little sod to fit in there. Anyone else found/suggetst a solution? Adrian
