On the last lap.... having resolved all the niggles on #8, which included having the poxy carbs being taken off/on 5 times before i could stop them flooding (ended up lapping in a new seat on the needle valve (unobtaneum) ... ). also tap leaked, so service kit fitted to that (3rd attempt at getting the right one from M&P).
thought i'd treat it to a new iridium plug ... sodding thing wouldn't start ... put old plug back in ... carbs off/on (AGAIN !) bingo. .. she lives !
, seems to only need half choke from cold, so some adjustment required there ...
full pre flight checks carried out ... and a round the block ride as a shakedown .... all seems good so far except the front tyre is absolute sh*te ... goes round corners like a threpenny bit (if you don't know what that is, then you're far too young to be reading this sort of material) ...
local tyre depot (who pride themselves in supplying ANY tyre for bike or car or van or lawn mower) .. reckoned i must be mistaken ,,,, a 100/80 - R18 just doesn't exist ... bunch of tossers!, so i got on his PC, and showed him yamaha spec for the srx ...... 'oh' he says ... 'hang on, i'll call bridgestone' ... 'we can get one, special delivery .. 2 week lead time' ... shan't be going there again ....
oh... message for Bill .. 2 things i've noted about these (bluddy) carbs ...
1. item 42 in fowlers exploded view of the carb is called 'pilot screw set' . it's a spring loaded needle .... no information about haw far it is screwed in , i have 2 spare units here, one was backed off from fully home 1.5 turns, the other 2.5 turns, so at present i have #8's set to 2 turns.
2. item 43 on fowlers pic (the needle valve set) ... when i removed this from #8's carb, on top was fitted the tinyist filter, about 8mm dia clipped on... not seen this on any of the other standard carbs i've stripped ... maybe left off, 'cos once blocked with crud it's going to be a 2 hour job to get it cleaned.
