Hi all! I recently bought a 1994 VFR 750 with 67.000 kms on the clock. Unfortunately it had no service history, the owner claimed it had been done by his brother or brother-in-law over the years he owned it. However due to the bike's reputation of being bullet proof, it running fine and being cheap, I couldn't resist buying it. First thing I did was change the oil, oil filter, air filter and fuel filter. After driving it a few times I noticed a very small ticking noise coming from the engine. At first I thought it was the natural sound of the cams & valves but the ticking has become more intense, as can be heard in the video. Furthermore, I caught an incident on camera where the bike seemed to stall of even hit something after a small rev. What do you guys think of this ticking noise? Is this the end of this block? First thing on my list is replacing the spark plugs and see what the effect is. Valve clearance needs to be checked and carburetor has to be synced as I think it started running rough. I am however a bit cagey running the engine due to it ticking.
Change the plugs, but I really suspect you need to go thru* the carbs, including a synch. Did the bike sit before you got it? *Definition "go thru": A real, proper V4 carb clean and highly recommended 0-ring replacement. It sounds to me like it's sruggling to idle, running rough, and may be dropping to 3 cyl at idle. That clunk is just the starter clutch grabbing slightly when the bike died idling low/rough and kicked back a bit. I've heard it many times on 90 - 97 VFRs I've worked on. If the bike has had any kind of oil change schedule, it is 99.99% just fine. Just needs some more TLC.
Thanks for the replies! Not yet, will check when changing plugs! Yes the bike sat most of the past year, owner said he only drove it from storage to his house for about 6 km. Dreading the carb clean and sync a bit, contemplating trying to do it myself and learn or sending it to a mechanic.
