Question about 1987 Yamaha FZ 750 MG (Europe-US)

1 Answer

Broken exhaust This really burns my britches. The two nicest days of the year and I am without a ride. Simple job. Take off old, full of holes, rusted exhaust and put on new bright shiny clean one. Left side come off no problem. Right side..oh look, I never noticed that there was a bolt missing here...and then....oomph....this one broke off, too! Damn! Ok...drill out the center of one. Get a nice little hardened steel bolt retracter...turn it counter clock wise.....Damn! That broke off too! What now? I mean really. What now? I have about a half a cm to work with on one bolt and nothing sticking out on the one with the hardened steel piece inside. I could really use anyone's advise and help here.

The sad fact is, you will probably be etter off removing the head and having the busted bolt removed and repaired, either by you or a machine shop. You have limited room, a ruined, hardned extractor in there.... going any farther with it in place will most likely F-it up more.

Cutting out really bad

Hi, Kristy would help me a lot if I knew the year-make-model and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.

Suzuki gsxr-1000 2011 exhaust valve actuator fi fault

You can definitely ride it without the servo, all 3 of my bikes have the FI lights on as I have aftermarket pipes with the servos disconnected. But I would make sure the servo is open, you'll lose a little low end power, but you won't sacrifice any top end.

My problem is my front brake. I have to open the bleeder on it to release the pressure before i can ride it or it will lock up on me. Now is this the caliper or the master cylinder that needs replaced.

Do not despair, it is a relatively easy fix. Your brake master cylinder is dirty and plugged with rust. You will have to take apart and clean your brake master cylinder. Consider purchasing the rebuild kit and replacing all the rubber parts in the master cylinders and the caliper pistons. This will ensure you many trouble free years of operation in the future. If funds are tight a simple cleaning of the master cylinder reusing the old parts should suffice. When you rebuild your master cylinder you will need to look down the reservoir at the large brake fluid feeder hole. Right next to it is a tiny pin hole. That is the brake fluid return hole for the reservoir. It is probably plugged with rust or dirt. When it is plugged , you can drive a short distance and the wheel locks up. Open the bleeder screw to release a squirt of fluid and you can drive back home before it locks up again. Clean out the hole with a single straight bristle from a wire brush and see if that fixes the problem. You may not need to disassemble any thing to get the systems working properly but you will need to do a thorough bleeding to get all the rust and dirt out of the brake lines. This is a common problem on all older machines when the brake fluid is allowed to sit in the system for many years unchanged. Use only new DOT 3/4 brake fluid when refilling the reservoir.

Just bought a 1993 suzuki gsxr 750. has been sitting in a garage for 2 years. we took the carbs off and cleaned them really well, changed the oil, and air filter and we added new gas. bike starts up and...

If is runs better with full choke, then the bike is lean, check for air leaks at the carb manifold, vacumn cracked hoses, non standard exhausts, perhaps the mufflers have rusted out while sitting

I am buying a 2003 thunderbird cruiser, what shoul I look for?

Know that most shops will probably refuse to do repairs on your bike if it is more than 10 years old. Your 2003 is getting close. Check with a local dealer and see what their policy is. Most all shops use this same standard. Parts availability is the main problem. In any event, below are things to look for if getting a used bike.

Does the engine start easy and idle smoothly? Does it accelerate without hesitation?

Any smoke when it starts or when pulling away from stop light? (Bad valve guides).

Any smoke when riding at 30mph? (Piston rings worn or possible previous seize up).
Does the clutch engage and disengage smoothly? Clutch lever easy to pull?
Any oil or coolant fluids leaking after a ride?
Do all gages work? Lights, horn and flashers?
Any red lights on the gages lit up? Any computer codes flashing?
Do front and back brakes operate and stop smoothly?
Is the motor oil pretty clean or really dirty? (Sign of how well the owner has cared for the bike).

Is the oil "white-ish"? (water in the oil. If motor is water cooled it's usually bad water pump seals).
Any funny sounds from the gear box? Anywhere else?
Does it shift smoothly up and down the full gear range? Neutral light come on properly?
Sprockets still have rounded tips not pointed? Well lubricated chain?

Good tires? How old is the battery? Two years is an old battery. All lights work properly?
Is the upholstery good? Plastics cracked or broken?
Gas tank badly rusted inside? Do the wheels run true or weave?

Do the forks look bent from a side view or front view?

Does it drive nice or is the bike squirrely to drive? How about around curves and corners?

Ever been wrecked? What service work has been done in the past?

With the handlebars driving straight ahead, is the front wheel pointing a slightly different direction?
Do all accessories work properly?
Ask what doesn't work on the bike. What known problems do exist?

These are things to look for. I hope this helps.

Please rate my answer. Thanks.

'02 Yamaha XJR1300 Rattle/vibrating noise from bottom of engine

how do you adjust the headlight beam on a xjr1300 naked 2002 bike, is it as simple as undoing the 2 bracket bolts at the sides of the lights and re-setting the lights to a new level ??
currently it seems to be set for riding with a pillion passanger or heavy load at the rear as the lights are set low, no one flashes me even if i ride at night with full beam on !

thanks xjr cambs

How do you replace the exhaust downpipes on a ZZR600

Well, the hole can be welded using a new half piece pipe if the rest are good, else it is an easy job for a muffler shop to do it, but it is your call.

I have been ill for over 2 years and my2007 has been stuck in the shed. it had its first service, but has not been serviced since, it has only done 1600 mls. will this affect the service history.?

Putting a bike up for a couple years without taking some precautions precautions isn't really good for them but it all depends on the storage conditions. Old gas can coat and clog openings in the carbs, rust forms on the steering tubes, paint fades in sun exposure, gaskets and such things dry out and leak, etc. If you have had her serviced and she runs and rides well thendo not sweat it. Hope you are back on your feet and able to enjoy your bike so get out there and feel the breeze on your face.

Basically you just have a relatively low milage bike that is three years old. If you are concerned about waranty issues (is it still under warranty?) most waranty maintrence requirements are scheduled by miles so you are probably are still okay. If you looking to sell it just tell the potential buyers you got sick and were unable to ride it. You can say I just had her serviced but that is about all you should ethically feel to say. Any buyer should test drive the bike and make their own decision.

Pulsar 150 - Some knocking after i got a service 3 days back...

It could be the exhaust baffles which are in the exhaust pipe tht have given away, you can remove the exhaust pipe assy and get it cut underneath and get the baffles electric welded..or rather spot welded and weld the exhaust back but the chrome will burn off and rust may thn take over ..or unless you paint tht area black( heat ressistant paint.),or better off is to replace the complete exhaust pipe assy.
Hope this helps!

Loud Exhaust leak

I wouldn't run it like that until you get those bolt holes cleaned out. The exhaust gases will leak out and burn/melt stuff nearby and you run the risk of scorching an exhaust valve requiring a head-job. And a head-job isn't as much fun as it sounds like it would be.,,
