85 Tri-Zinger

[Jon Boy]

ok, just wanting to double check a short list of mods/upgrades i figured up.

1. Grand National exhaust or similar type
2. Towny or QT50 2 speed trans
3. PW50 ignition system
4. delete oil injection system for premix
5. lighting (2 ways to possibly go here)
6. Boyesen Reeds

any other mods/upgrades or any mistakes i've made sofar? everything i'm planning on doing i will be basicly considering a bolt-on. i want to be able to go back to stock set-up if i want.

and just incase, thanks fellas for the info and help.

Did drilling the exhaust out help it pull harder?

i think i'm just going to wait till i go to my buddy's this weekend to do it. did soak the chamber in a strong degreaser overnight. it did an ok job at it, did wake it up more. got a short vid running a few laps in the yard on my youtube channel, but i had forgotten my helmet. so i'm not going to post a link.
planning to do a couple other things this weekend too, like checking the reeds and such. reminds me i forgot to add getting Boyesen Reeds to the list. might pull the oil injection also. i just feel more comfortable knowing i don't have to worry about the oil pump going out. i'm not wanting to go all out building it up, but would like to do a few upgrades when/if i come across stuff.

after going over the YT60 sofar i've noticed i need a clamp for the rubber intake going to the carb. it's just got a zip-tie on there. also took it out for a spin at the local river trails and a big stick popped up and managed to pull off one of the dust seals on the fork. they're a little rough and zip-tied on as well, so figured i'd change out both sides. do the seals just slip on and hold with a tight fit or is there some kinds of clamp or spring for them? been searching, but i just haven't found the right place yet i guess if they're out there. it's looking really good sofar with the little zinger other than these few things it's just a matter of replacing some bolts with the correct ones and a sticker kit.

i'm treating this the same way as the 125m, anything that'll be done to it is basicly going to be a bolt-on. no cutting/welding nonsense and any part added will be what will get modded to fit as a bolt-on. i just like the idea of being able to go back to stock original.

ok, here's the first mod to it. it's just roughed out to fit for now, it still needs a little work to get it looking and working better. now i can 2 finger brake and no more finger pinches.

Tektro 313a "Trigger" brake lever ($10-$15) from one of my old BMX bikes. it's the rightside lever, but they do make a leftside also, which will be the one getting used in the end after i figure out what needs ground down to work smoothly.



next plan is some bar risers, which my buddy found something that works nicely. he showed me some threaded spacers he has for his oil-cooler on his race car. we tried them and they worked perfectly, now i need to find a set just a little taller than what he has. also thinking about some differant tires for the rear. anyone have pics of a YT60 with something like 13x6.5x6 rear tires?

EDIT: almost forgot Thorpe, got the exhaust opened up now. little thing screams pretty decent now.

Heck yeah! Glad to hear!

Dust seals on the forks are discontinued. I found some NOS ones at a local Yamaha dealer a few years back. Keep looking on eBay for "Nice" used forks....You may need them for the seals.

*Also, does anyone know what kind of pipe is on my Tri-Zinger? Pictures on page three of this thread.

Thanks!

don't think anyone's figured it out yet.

want to say it almost looks like the silencer on my 77 YZ80, but it's not exact.

Thanks......I wish I knew. I am going to be tearing my Zinger down for a full restoration very soon. When I do, I will take some beter pictures of the exhaust. maybe that will make it easier? My luck it will make things more complicated...LOL.

Thanks,

Ive heard people complain of the exhaust getting clogged up and these having no power because of it, countless times.
