Hello Everyone, I have three FZ750's. Two 1985 and one 1987. All bikes have sat for a decade and need tlc. I found only one shop in Calgary that would tune the valves. They were like "this is a big job". I'm cool with it knowing that the bike is due proper maintenance. I did have some issues with my fuel pump, so I thought. It was a corroded solenoid giving the pump the wrong electric. I tried a couple of fuel pumps and they were all the same... not pumping. Found the corroded solenoid and the pump runs great. Now she needs the valves adjusted and the tank coated inside due to rust. Are there any other old FZ's out there? Love to hear from you. Cheers, Sean

Hi Sean. Thanks for registering with us. I don't want to discourage you from using this forum as it is full of very useful information if you care to search for it but.. our facebook page will get you much quicker answers to any questions you might have regarding your FZ. As far as your valves are concerned I would be asking around for a well seasoned mechanic. Someone in his mid fifties who has been around bikes for the majority of his or her working lives. Valve clearances aren't too bad to check but if any need adjusting then it gets slightly more involved. Personally I would have a compression test done first to see if it's all up to spec. If not I might be tempted to check valve clearances to see if any need adjusting. Depending on mileage of the engine or how it's been stored it may be the case that valves need to be lapped in order to regain full compression. I just hope you can find someone who is willing and capable of doing the work for you.

Hi Sean
or perhaps like me you think Facebook is the devils work... Like Graham says checking the valves is simple enough - adjusting is where the fun starts as it's cams out time.. The difficulty I had when doing this last summer was sourcing enough shim replacements - that and the fact that some had been ground down and were no longer the size etched on them, Cams in and out 3 times due to that last oversight..I spent hours and hours on it before I realised what was going on.!! There a lot of bolts to torque on the cam caps and sprockets and I had to butch a spanner to turn the cams too. If you know someone who has done it before it will help a lot. Youtube too can help.
Good luck!

Good point Jamie. A decent micrometer is very useful for checking the thickness of your existing shims.
