Question about 1979 Yamaha TX 750

1 Answer

Got a rusty old Yamaha 750 SF motorcyle in the garage. It has been sitting for 10 years at least. In pieces. Want to move it out and maybe start working on it but the rear break is seized up. Need to free it up so I can move it out to my work area.

To free it up you are going to have to take the wheel off. Remove the axle nut and washer. then use a plastic hammer or rubber mallet to punch the axle out of the wheel. Use a brass punch if you must use a punch. Using a steel hammer or steel punch will likely screw up the bolt threads.

Once the axle and spacers are out then you work to free the inner hub from the outer hub. Once free, you can get to the brake shoes and actuator shaft. I am sure the shaft is stuck in place. Use WD40 and the brass punch to remove it.

You are a braver man than most. The bike is 30 years old, abused and in need of hours upon hours of work. Parts are not going to be easy to find either. Google " motorcycle salvage honda ". Also try " antique honda motorcycle parts ". Check your library system for a service manual. Also try www.repairmanuals.com . You must be related to "Scotty" of Star Treck fame. He could fix anything.

Best wishes on the project Scotty.

Hi, Martin if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or better, any readings in the 11 volt range you need to do a proper load test on the battery and replace as necessary, any readings in the 10 volt range you have a dead cell and replace the battery.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove your air cleaner and clean and re-oil per Mfg. specifications.
6. Remove the carburetor, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Remove fuel valve and filter disassemble and clean as necessary, remove fuel lines and replace with new ones.
8. Replace spark plug with a new one and check for spark.

I need all manual of yamaha fzx 750 , i don`t have any informacion


Hi, Anonymous the vast majority of service, parts, and owners manuals on the internet are "FREE" to download and all service manuals contain wiring diagrams in the back pages. The rest usually charge a modest fee around $10 sometimes more and there is a handful of obscure, rare, obsolete, and very old models that are no longer or never were available, then there is eBay where you may be able to find what you need at a very high price because of its age and rarity. Most of the "FREE" manuals will cover your exact make, model, and year otherwise one will be provided that comes as close as possible to your bike and will have most of the same info that an exact manual would have.

It seems like a lot of slop in engine to drive train


It is very typical (and intensely annoying) that when you transition from accelerating — however slightly — to decelerating — however slightly — there is a big bounce as if there is enormous slop in the drive train.

Every motorcyle I have ever had (Kawasaki 175 2-stroke, Honda CB350 twin, Yamaha 650 twin, Yamaha 750 special and Suzuki GS 850), and every motorcycle I have ever driven (Honda CB 50, Yamaha Mini-Enduro 60, Honda Hawk 400, Kawasaki 750 LTD, Yamaha Virago 650, Yamaha Virago 750) has had this “feature.”

Wont start


got a charger and it ended up being a dead battery.---- If that's the original battery, it's probably toast. You'll probably do well to search for a replacement at this point. Bike batteries are generally considered short-lived. The longest lasting battery I ever had in a bike went 9 years*. But that's so far away from a normal lifespan it's almost ridiculous. I suppose the average is more like 4-6 years but the modern, Maintenance-Free types seem the best.

Oil change


When storing for winter oil should be changed before so as to remove contaminates (certainly would not hurt to change-falls under the category of severe usage), then you don't have to worry in spring when you pull your bike out. Hope you drained the carbs and kept the battery charged or you could be looking at spending more money.
