Hi all,
I just got my fazer back on the road after about 5 years and I’m having a few problems. First major problem is monumental clutch slip. Initially when I got the bike back on the road, the clutch was fine, but it seems to be pretty bad now. Tried all the things on the clutch slip thread, i.e. making sure there's no gunk behind the front sprocket cover. Taken out the clutch push rod and autosol'd it, so it can move freely (however when returning the push rod into the engine, it feels a bit 'notchy'/ like there's a bit of resistance there). Normal?? Adjusted the clutch free play on the lever, as per the manual to give it 25mm free play, which seems to have made it worse.
Thought it might have been the oil (oil with friction reducing agents), so dropped the oil and put fresh oil in with wurth wet clutch engine flush, suitable for bikes. Then put Halfords 10/40 bike oil back in, all to no avail...last thing to do I’m guessing is adjust the clutch on the engine side. Silly question, but is the adjuster screw and locking nut found behind the front sprocket? Or is it the other side, near the clutch basket etc?? Maybe it’s the case that the clutch plates/springs need changing. Slip seems to get better when the bike is warm
Problem number 2 - carbs!
Took the carbs off, cleaned out the bowls and ultrasonically cleaned all the jets at work. Didn’t take the mixture screws out. Should that have been done?? Put everything back together and had massive over fuelling from carb 1 and 2 (2 left carbs), so gave the bike to a bike mechanic, who sorted that issue and he also balanced the carbs (he said), but idling still doesn’t seem to stable. Engine tends to bog down when pulling away and when shutting off throttle at a junction for instance, the engine takes time to return to idle. At idle it tends to rev on its own sometimes. Also when starting the bike with choke, full choke makes the engine sit at around 4-5000rpm, and I have to fettle the choke to get it to sit at around 3000rpm. Is 4-5000rpm a normal engine speed with the choke on? Pretty sure I’ve got the choke and throttle cable round the right way...reset the TPS also, which I think improved things a bit. Plugs were changed just before I took the bike off the road a few years ago, do they degrade even with little or no use over time? Lastly, the inlet rubbers have a few minor cracks, but nothing going all the way through. However if the engine is pulling unmetered air in through the inlets, it might contribute to rough running. I don’t fancy paying 75 quid for a new set, so maybe a repair with araldite. Any ideas would be greatly received or if there’s any fazer riders on the isle of wight, please give me a shout.
