Author Topic: 1984/5 Yamaha Tri Zinger60 (Read 3137 times)

After nearly twenty years I found the old Yamaha tri zinger that my best friend has as kids. I tracked down the school teacher that the neighbor sold it to, he had it rebuilt at some point and his son had it.

The Son had it in a storage shed for years n years. I now have it for $400 bucks
Pardon the torn down photo, I got a little excited to see what I needed to order

Purchase list so far
Amazon : makuni carb replacement with throttle cables and all.

RMATV: fuel cab
Fuel and drain hoses


Need to source :
Tires
Wheels
Some plastics if possible


First sight came with good news. A cup of fuel and a little starter fluid it fired up to an idle pretty easy.

The throttle and carb are completely gummed up and a replacement carb is only $22 bucks so I ordered it with complete cables (delivered Friday)

The spark plug looks good but I will replace it anyway later on.

The question I have folks is can I delete or reroute the oil injection pump and use the same mixed fuel I use in my other bikes?

I removed the plastics and wiring harness out of my way. I removed the spring/throttle cable assembly from the injection pump, there is no electrical connection what so ever ( I believe the Yamaha blaster had a wire to a dummy light to say you needed to add oil) that leads me to believe I need to do anything other than fab a block plate /cap to cover the shaft from the motor?

Suggestions. Knowledge?

This brings back memories, I had 86 KLX250 that I wish I still had.

Anyway you are 100% correct all you have to do is blank it off and run premix. If I’m not mistaken they used to sell kits for doing that.

Tri zinger is a very fun little toy. If the oil pump still works you are better off using it. But you can disable it and use mixed gas.

Ok replaced the oil injection with this

Installed my amazon carb

Notice any differences in parts?

The carb would allow it to run at wide open throttle but just barely. With out the float being able to manipulate the first jet, no idle, The other adjustments are honestly to short. Going to see about sourcing a new carb of higher quality,

But it runs. It rotates the tires.

Further update

Found out why the new Yamaha Genuine part carb would not run

The exhaust pipe was 90% plugged with oil. I had given up and taken it to the local shop. They discovered it and burned it out with a torch

It now runs via video https://youtu.be/1RipuVINS6w

I ordered some new tires as these are not holding air at all, bald as You can see.

The air/fuel mixture is off as I discarded the air box for a direct to carb filter.

Sanded the plastic today in preparation for a friend to put on some black automotive paint.

Negative has nothing to do with hippyland, I’m married to a former ER Nurse Ken.

Although for the record with all the idiot drivers here I do now always wear a helmet when on bike or motorcycle.

Traumatic head injuries are nothing to sneeze at. I protested at the capital in the early 90s over the passing of a helmet law. If you are 18 or older and have insurance, then its your choice. My choice is to not take that chance. Kids don’t have the ability to consider those ramifications so under 18 should be mandatory IMO, but I’m not gonna lecture others.

What I have seen and found at this age. While the helmet might protect their head. The weight of the helmet will injure there neck with just as much potential for issues.
Utah has removed the requirement for helmets on kids in a few spots take side x sides for instance.

The bike helmets on the other hand are a happy medium for the area. This summer Throttle block, and a open space to learn and he will have his bike helmet on.
Snow and snow cloths not so much

I didn't watch the vid. I assumed that it was Dave trying to ride it after he insinuated that.
That being said, I stand with my original smartbutt post.

My previous reading says porting is kinda minimal because of the size of the motor and such. Think I’ll keep it stock for the boys safety. You know. The no helmet and all lol
