Tri-zinger mods

[Ladnerboy700]

I have a 1984 tri zinger and I am wondering if anyone knows of any mods for them like the governor to speed it up...this just a strictly for fun grown ups to play on bike not kid ridden!

Thanks

The only governor that I know of on those is the screw with the locknut up on the thumb throttle.

yamaha 480 2 stroke bolts in to your frame that the fastest mod i can think of if you go to the world class help section they have a list of all the parts that can go on a tri z

There is a governor plate in the exhaust port of the cylinder where the pipe goes. It is a disc that has a smaller hole in the middle. I think there is another somewhere in the exhaust piping but I haven't ever seen one.

I am running an open filter jetted to specs but its like it has no power band. It just pops on top and won't clean out....NOTE: it did this stock! From bottom to mid is very powerful with wheel standing response but top speed is like 15mph...Is this normal? This is my first zinger so I have nothing to compare it to....

[bcredneck]

that plate dc was talking about kills your top end but makes more bottom end power get rid of it

The smaller gasket has been changed but it just pops erratically on top the plug is tan and no signs of lean or rich mixture...my PW50 is the same engine and it runs out fine...could there be an ignition advance on it?

Have you cleaned out the exhaust? They like to get clogged with spooge as the passages are small. I was tinkering with mine, and you'd be surprised how much faster it is with parts of the exhaust missing. Start by taking the silencer off and see if that helps, if not take the expansion chamber off, if it cleans out and pulls you have a blockage in the exhaust. Have you cleaned the carb? You may have sediment blocking some of the ports. My tri-zinger will pull pretty good with me on it's back.. It'll run at least 30 mph. I'm going to have a pipe made for it. It should pull much better with a better straighter, pipe on it. You could also have a short in the wiring with the start/run feature maybe.

[Ladnerboy700]

Everything is clean...its a new carb from Yamaha and the pipe is an out of frame off a PW50 none of this helped....I changed the on/off/start switch and still nothin...the only thing is to pull the cylinder back off and do some port work...

UGH this is aggravating!!!!

Tri-zinger.. not Tri-z..... Bit of a difference there.. although bcredneck, I can imagine you shoe-horning a 480 in a Tri-zinger frame... Might need some extra braces in the front though...

[dcreel]

Have you changed the clip on the needle one way or the other?

[Ladnerboy700]

The clip has been positioned every way possible....carb can be ruled out I just traded it off the pw and nothin...it just leaned out a bit because of the stock jets...the only 2 things that I haven't swapped is 1. THE ENGINE 2. THE WIRE HARNESS

[dcreel]

What I don't understand is that the YT60 and the PW50 use the same carb? Same jets, etc. in the carb between the 2?

[bcredneck]

sorry i thought you had a tri z my sister had a pw 50 the ignition was off a moped it ran better than stock after we did that

[Ladnerboy700]

They are the same exact everything just the pw is missin a tire lol they share the same engine accept for the air box and exhaust....is th zinger suppose to run out like a banshee or stop at a given RPM and act as if it has a rev limit on it?
