The early Honda's sure did suffer with rain due to the crap metal plug caps.

Pretty certain mine had phenolic NGK caps, Jerry - may have been fitted by the PO, as I bought the bike second hand @ 2 years old. IIRC the problem area appeared to be where the non-removable HT leads were bonded into the coils.

Wouldn't have been a problem if I had bought an RD400 like I wanted to, but my father (who was guaranteeing the bank loan) wasn't a fan of two strokes, hence the Honda.

Not a great bike - sieze-very-quickly flappy front brake caliper which was also reluctant to stop when it got wet, loads of problems with the carbs overflowing (which wouldn't have helped the sub-40mpg fuel consumption) and dubious wet grip TT100 tyres. I didn't keep it very long - sold it privately after about 6 months taking an MZ TS150 in P/x. Actually preferred riding the MZ !
