[Tri-Z 490]

This is my 1985 Tri-Z its basically stock. It has an answer silencer and answer steel bars. I got holeshot XCT's on ITP aluminum rims(not pictured). as far as the motor goes I am guessing it is stock but I haven't had a chance to rip it down and look at it. All I know is that I beat a 2000 banshee in road race!!! It was close down low but I still had him but once I hit 5th it was all over. I have another Z That is black and red that ones not as fast but has plenty of power. I will try and get pics of tha one when it gets a little warmer out.

Mods.. The red Z(1985) was owned and raced(3x in 85) by a yamaha dealer.It has some minor engine mods,still has the stock piston/ring.The pipe is an aftermarket pipe made by yamaha that only a few others have.DG silencer,boyesen reeds,uni twin filter.
The Blue Z(1985) I bought in 2000 in boxes(80% complete).I drove 11 hrs one way to pick it up.I restored it to the way it is in the pic.It took about 5 wks to complete......its never done,I'm always adding things to it .polishing.painting.etc The motor was taken from a tri-z donor in running condition so I dont really know whats done to it.
I only ride them about once every 2 or 3 months.The red Z has quite a bit more nads then the blue Z.I keep them almost spotless and well armoralled,waxed or whatever. Wheels are always being switched around with the blaster,so if you see dirt on the tires it came from my blaster.
The original Tri-Z stickers are in excellent condition too,blue one is a lil tore up on 1 side and most all the other stickers are good too.The seatcovers are CEET,Blaster fits tri-z too.
I also have 2 disassembled Z's and enuff parts to keep me going for awhile.
......I can talk Tri-Z's all nite ,just look at the pics These are some closeups,there are other pics elsewhere on the trike brd too.

[Tri-Z_Jim]

The tire on the red Z is a dunlop.Not sure what model.I bought it from dennis kirk about 3 yrs ago.The blue Z is still has the original.If it wasnt -3 I would run out to the garage to get the model# for ya

I have an 86 Z that I'm fixing up. I haven't had much time lately though I have been able to ride it around a little, just to make sure it runs. My pic is in my avatar

Here's my '85 with the following:

UFO Disc/Fork Guard, Screen Number Plate, MX Bars, Pro-Grips, Twist Throttle, "Air-Box" Fuel Cell, Bill's Pipe, CT Silencer, Boyessen Reeds, Clamp-On UNI Filter, 14 Tooth C/S Sprocket, +2" West Coast Swingarm, 2.5" Hub Spacers, and 18x11-8 Turf Tamer Knobbies on stock Z rims.

Yes, no chain in the picture. It has one now. :-D

It runs great. If anything is done to the motor internally, I don't know, I haven't had to get into it. It's kind of an ol' Motocross 3 wheeler replica, but I need to add an extended axle and re-install the tether kill switch to complete it. I also have a 38mm Mikuni Flatslide laying around that used to be on my 84 Tecate. I'd like to get it on the Z too in the near future since the 84 is history and the carb is just laying around. I also have some reprint giant Tri-Z decals for the rear fenders. But I don't think the fender on it now is nice enough to use the decals on and I'll probably end up putting number plate background and numbers back on it.

Oh, & the best mod of all: The JT red lightning bolt decals on the airbox (or fuel tank) cover!

:-D

Another Blurry One

[Tri-Z 490]

i just bought a DG pipe for mine how muc h better then stock are they? Can you still get other Brands for it? I want to get some boyesen power reeds with the pipe and then get a K&N clamp on for it, But what kind of jetting is needed? how much quiker will it go then? Also how is the port and polish do on the performance?

[TimSr]

Ive got a DG on mine, and it seemed to improve the bottom end, with no noticeable change anywhere else. The Boysen Power Reeds seemed to improve throttle response and top end. The K&N is easier to service, and doesnt begin to glog as soon as stock , but this is not a performance modification. The reeds make it run a touch richer, while the pipe had little effect on carburetion, and I did drop the needle to avoid plug fouling on trails, but Ive never had to tough the stock jetting. Ive also been through .20", .40, .60, .80 overbores twice, which has not required a change in carburetion either. Since it easily pulls the front end up in any gear, whether I want it to or not, and will climb like a billy goat, Ive never even considered to bother porting it.

[Jeroboam7]

Tim,

You know the reason for porting so don't pretend you don't, its for absolutely no traction anywhere!!! LOL And so you can throw large piles of earth up in the air and not move, therefore eliminating that wheelie problem.

490,

Porting can do anything from giving the bike more low end or it will turn it into an top end screamer, it all depends on what you want and who you have do it. Like Tim I rarely if ever change jetting usually main jet is a 430 with the 38mm Carb, when I hit the sand piles I go up to a 450 main just so I don't burn it up! As Tim said the DG pipe is basically a stock replacement pipe I doubt you are going to get any vast improvement out of it! If you want a different pipe you will need to talk someone into making it for you, and a one off pipe won't be cheap! The cheapest mod to make it go faster is to have someone mill the head.

I would talk to the guys over at FTZ, they will make you a custom pipe with noticable power increase for around 3 bills
