The tri zinger.

[spentar]

Winters coming and the zinger will be my project. I want to make it faster, ive already eliminated the oil injection to premix, i bought an air filter to replace the airbox, and thats about it. I have a dg pipe that im getting in less than a week too. Im planning on getting an oil injection block off plate to eliminate the internal gear, which ive heard will possibly make the bike rev faster. But what else can i do to give me the edge? ive heard of the yamahopper 2 speed tranny, but thats alot of work for a 15 year old kid. I know they got rid of the 70cc big bore kit, I dont know if rebuilding it would help it rev higher or pull harder. But if anyone has any ideas i would like to hear.

pull the crank and have it knife edged and lightened. anything to help cut down on rotating mass will help get it to rev faster.

I'm in the process of building my tri zinger too.

You can buy Boysen Power Reeds, bore the piston up the next size or buy a new top end kit :

There's got to be other tricks to getting a little more out of the tri zingers! I'm going to swap my tires off my alt 50, was thinking about pulling the gas tank and carb from my Suzuki mini quad just to play around with it. I also ordered those large foot pegs from the 3ww shop.

x2 on boring the piston. I've had great results with that.

you've just about covered it i think. not too much you can do with the zingers without opening them up for internal mods.

What are the internal mods? I'd like to hear about these mods and what kind of results do you get out of them?

Thanks!

NO! do not buy a after market knock off kit. I purchased a kit from the people in your link earlier this summer, the kit was complete crap. I was getting only 60psi for compression.
TRUST me on this your way better off getting oem even though it costs alot more. Just forewarning you.

Also to the fact that russ98atc's zinger blew up today with the knock off kit. Thats only a couple months old. And i assure you he was mixing to the correct spec and did nothing wrong to make it blow up.

It was broken in properly and taken care of well. Granted yes i did run the piss out of it this summer till now, but it showed poor performance from the start

Im planning on getting an oil injection block off plate

When you get that let me know. I'd like to check it out and see how it goes in as I'd also like to get rid of the pump.
We'll be in Sat Spencer so I'll grab Russ and we can head over to your place with the pipe.


Yeah Russ it didn't seem to run right at all. We're just keeping Con's zinger stock. We bought the wheel adapters that will get us to 3/120 so
we can get some real rims and tires on it, but that is about it....other than a new carb.

This winter we are concentrating on redoing my LT250S. Found a powder coater and should have new plastics for it
this next week.

I want to know more about this yamahopper two speed tranny mod?

[bandito90]

@riverrat it's a two speed automatic that came on the SG50 Sting,LC50 champ and MJ50 towny.Not sure what needs to be modified to put in a zinger frame.

I'd like to know a little more about this mod as well. I rode Andy's (crazy70man) 2-speed Zinger in the drags at Trikefest '12 and the shifting is absolutely great. The only problem with the setup is the gearing is too tall, as Andy has mentioned in other threads. It's a bit tough to get the machine rolling from a standstill, even in first gear. Once you get going and it shifts into second, you're really rolling along at that point. As Andy said, I'm sure it approaches or even exceeds 40mph. If the gearing could be brought down a few notches it would be an absolute "must have" as far as Zinger mods go.

[CRAZY70MAN]

Here ya go Riverrat...http://www.3wheelerworld.com/showthr...t=speed+zinger John is right. The zinger will hit 40 with a 230lb adult on it without the NOS and a few more mph with it. The internals are a little involved...uses the mj50 aka Yamaha Towny moped crank, towny gears and clutches and right side towny cover as the crank is wider than stock zinger. Mine also incorporates qt50 rear gear in the rear end which I have never actually been into, just told by the great builder of it who recently passed away. The problem I beleive was that the original primary clutch for my original motor was drilled and machined to be very light. Well it was broken and repaired so I did not risk installing it. I bought a new stock clutch which was much much heavier. If I can get another clutch machined down and install some different springs.... I think it would be night and day as I have heard stories of this trike from back in the day and it is not there yet. The NOS helped but can be dangerous if you are not up to speed!! Give Raffa a shout...he re assembled my motor and did a great job. Gonna tear into it this winter and get to lack of low end. Still was cool to hear Fabio hit that NOS trigger in the drags at TF12!!

I just pulled my motor and installed the Boysen power reeds last night. I was wondering if anyone has ever made a torque reed spacer for their tri zinger?

I'm waiting for my new foot pegs and DG exhaust to arrive before I install the motor. I was thinking about making a spacer out of some 1/8" plastic just to see what happens. My parts should be here any day.
