Interestingly, Suzuki recommend the inclusion of Bars Leak in with the antifreeze for my RG500 with conventional cored radiator. I never bothered but after an engine rebuild I had an antifreeze leak but only when very hot. After much head scratching I tracked it down to a leak between the crankcase faces. With nothing to lose I tried the Bars Leak and it cured it and avoided me having to strip the engine again. Ten years later and a couple of antifreeze changes (without Bars Leak) it is still fine. I’m not saying it would work in a Scott or restrict cooling a little but would certainly be worth considering for a non-honeycomb rad?
