Re: Carb Heat Insulator. Cork? Update.

These BSA singles, both SV and OHV are very 'cool running' in terms of heating up the oil...OHV models in particular are known for it...Ian

Re: Carb Heat Insulator. Cork?

Prompted by John Parker's request for problem solvers, this is my solution for hot carbys. I machined a shallow groove on each side of the insulating spacer to take a 1/8inch viton O-ring sitting slightly proud of the spacer to be compressed/squeezed into the groove & against the barrel on one side & the carby flange on the other side to give a air tight seal. No other gasket is required. You do of course have to make longer studs to suit. My bike is 600cc & running Goldie touring cams & in Queensland (OZ) with summer temps of 30plus I have had no problems over a couple of years. I pulled it down recently & could have used the O-rings again but hang the expense, new ones went in.
