Just finished a major nuts&bolts rebuild of the 500 hundred from the ground up.its an 89 model and every seal,bearing,gasket and just about every part that needs replacing due to ware and tare has been,only performance mods ive made are a gnarly pipe and hitech dual stage reeds,the trouble is know when i come to start it back up. Checked all all the jets and striped and cleaned the carb but found a 190!! main 62 pilot and a 1 step richer needle!!, what i cant get my head around is that the plug was a nice light tan colour and it started 1st/2nd kick and hardly smoked,it was on 60-1 putoline mx7.After reading the jetting charts i settled on a 170 /60 combination but left the original needle in,but now its a pig to start,wont tick over,smokes like hell even on the same ratio and oil and when it warms up it dies as if its either still got the choke stuck on,wich it hasnt or its running out of fuel,only thing i havent checked is the float height but how do you do it,do you need a tube and an adapter for the float bowl or is there another way? thanks for any help and advice,the forums been a big help over the last 2 years its taken to finish this bike,now all i wanna do is ride the thing!!
