Well, I've just taken in the radiator for a "professional" clean (where they pull the side-tanks off, as opposed to spraying water into it), and I changed the plugs & leads yesterday
(gone from 8mm silco supressed silicone leads (no brandnames), Denso plugs (garden variety, v-groove, also badly fouled after only about 10-15 thousand km.. to NGK Iridiums with a tiny center electrode, one heatrange colder (they'll foul too quickly I think ) and some 8.8mm spiral wound cords which I got cause they were out of Magnecore KV85's, but these should do the same thing for $100 less, I hope)
Aaaannnyyywayyyy, I should get the radiator back in a while, I'll chuck that in and take it for a spin, and tell you all how it goes.. I expect some minor improvements in power / responsiveness, and a much better idle (it was pretty poor before). As for the radiator cleaning, I expect (hope for) it to run a lot cooler, as I have eliminated all other reasons for it to run hot.
P.S. Took mums Ka down with the radiator, and managed to chirp the tyres going into second around a corner, but it sounded like a full-sik (tm) blow-off valve... Never thought I could have so much fun with a 47kW engine
