HI mate. 90 psi is far too low for that gsxr engine. They usually run 150 -190 psi hot with no plugs in on the comp tester. What are your compression readings cold across each pot? I know 73 engines pretty well but not 76 so much, but they have similarity's right? If your ignition is only a degree or 2 out it will start ok. Use the std twin electrode plugs maybe?
+John Jackson the problem i had was a coil checked out at correct homes then when running it whent down to nothing never had where ya check leve the meter on and it then goes from 3.5 to nothing changed coil fired 1st time
Hi, have you worked out what it is yet. I have a gk71f import and similar level of frustration with awful compression. Also is the timing inspection cover a normal clockwise thread? Ta andy
i have had it started but electrics are old on this one everything has to be right carbs compression etc now it seems to have gone again of all the bikes i have built thisn one you cant get new parts for like pistons oversize then you know thats right its a case of buy some barrels check dimensions and chose the best ones
Carb problems needs to be syncronized..
