Congrats, thanks for sharing! Just goes to show persistence and a little ingenuity will pay off in the end! Not the first time us DIY-ers have had to "invent" our own specialty tools, ha!
Thanks, please count me in! My poor old 750F Super Sport is starting to feel neglected after his new bigger brother showed up unexpectedly ('97 Triumph Daytona TRIPLE!)
THANKS, good to know! May have to keep an eye out for a decent set of those on eBay - sure would be nice to know all those side orifices are clear too!
Thanks amc49, excellent recommendations across the board! Pretty sure the plugs were bone dry when I pulled to check (both original and new one I installed afterwards), but may be worth checking again just to be sure.
Understand the limitations of cleaning the pressed-in idle jets - will clear...
Yep, seen some tough carbon deposits in my day, but the cylinder head and piston crowns of this bike were completely decarbonized only a year and a half ago when I had the top end apart, and I've only put a few hundred miles on it since. Seems unlikely given the low time on the engine since...
Thanks again to amc49 for continued help, as I continue to try and track down the source of this problem...
First off, good news about earlier compression test - low readings were operator error, ha! Been awhile since I did a check and forgot accurate readings only achieved with engine hot...
Well, surprisingly, after reshimming the valves on #4, adjusting both camchain tensioners, & refilling with Rotella T6 15W40 synthetic, I restarted the bike and she actually sounds pretty normal - at least nothing I can detect clearly as a rod knock or anything.
However, I'm now getting a...
Hmmm, must be getting old... (oh wait, I really AM getting old - 65 this year!), but I'm having similar problems with my '80 750F Supersport and need someone to clarify what mrmach5 means when he says his problem was "ignitors." I see he mentions coils (yep, still know what those are), but...
OK, dropped oil pan and inspected sump - very minor debris and nothing that looked catastrophic. Pulled plugs and inspected piston heads as best I could - nothing abnormal there either...
Finished checking valve clearances - all good except #4 (one intake & exhaust a little loose, 1 exhaust...
OK guys, got a 1980 Honda 750F Supersport with almost 29,000 miles on it. Recently drove bike down for the annual safety inspection we have here in Texas and noticed LOUD metallic tapping noise developed on return trip. Roundtrip mileage was probably less than 7 miles or so. Tapping was there...
Hey, count me in 2! Free parts will go a long way to counter-balance the fortune I'm spending trying to track down obsolete NOS parts for my Honda 750 obsession!
