"Will be ordering a 50.25mm piston soon" That'd be a wiseco.
FYI: I only use Suzuki pistons.
powersportswarehouse.com look up 2003 kawasaki KFS(kfx)80. Cheapest prices I've found.

I guess 2003 kawi piston interchange?

What about getting a bigger pistion? I'd rather not resleeve.

The first overbore with a Suzuki piston is .5 over. this is what you want.
This leaves 3 more bores. You won't need a new sleeve anytime soon.
The 2003 kfx80 is a green Suzuki LT80.

At the bottom of the parts list is the piston sets (piston and rings). $46.99

Are there any weak points on the frames? Will be painting soon.

LT80 · « **Reply #30 on:** May 18, 2015, 05:31:59 am »

The 2 tubes that come down in front of the motor (carb area) ~they can crack.
Where the 3 frame tubes come together on the bottom.
Neither is common but that's where to look.

Other than buying aftermarket shocks, are there any newer year shocks that perform better than the 87s?

LT80 · « **Reply #32 on:** June 01, 2015, 10:18:20 am »

I've heard that polaris mini shocks are better.

Well i know it's been awhile but my son has been on me about getting this project going again.

I got the new piston and had it bored.

I'll be putting the motor back together soon.

Think i'm going to paint instead of powder.

The guy i bought it from said that the cdi was dead but i dont think it is. The spark plug wire was mostly broken at the cdi. Only about 2 were connected and after pulling the boot off the wire i saw massive corrosion. My guess it was just a poor connection.

All the a-arm bushings need to be pressed out and replaced. They are basically welded to the arms at this point. Going to gusset the frame in a few spots based on lt80's suggestions.

Lt80, I had some ideas about modding the foot pegs so they can be taken off without pulling the motor. have you done this? how did you do it?

LT80 · « **Reply #34 on:** November 29, 2016, 01:50:04 pm »

Seeins you're a elite member, I'll tell you.

I cut them in 1/2 in the middle. I then cut 1/4 inch off. I then lathe a aluminum piece down to fit in the pegs to rejoin them. I leave a 1/4" washer (so to speak) on the lathed rod to prevent it from moving around.
Surely you get the drift and can make your own joining rod. Or I can make you one.

Geez, an elite member taking advice from a green horn...

That's exactly what i was thinking about doing.

Except i was going to drill some holes to put some bolts through to hold them. The washer seems much simpler.

I'm an elite member and I know nothing about Zillas and I will probably buy one soon. Nobody can know everything about everything! Lol. I still ask dumb questions here and there lol. I'm not going to let anything stop me from asking if I don't know.

LT80 · « **Reply #37 on:** December 04, 2016, 07:09:37 am »

So what's your question on Q's LT80?
LOL

All American · « **Reply #38 on:** December 04, 2016, 09:40:45 am »

Is it hard to find one in that shape? Would it be a good starter for my 6 year old boy? If you're looking to buy one, how much does something like it cost?

LT80 · « **Reply #39 on:** December 04, 2016, 05:57:33 pm »

Depending on shape, 400-1200

All American · « **Reply #40 on:** December 05, 2016, 12:48:57 am »

Did they make a lot of them? Just wondering how hard it is to get a nice one.

Q2W · « **Reply #41 on:** December 05, 2016, 10:20:39 am »

my advice is to check craigslist often. I stole mine... 100 bucks for one that's never been in the motor and not all hacked up.

most of what i see is 450-1200. And the 450ish one are usually in bad shape.

All American · « **Reply #42 on:** January 01, 2017, 10:49:42 pm »

How long did you have to search? I'd rather save up and get a nice one.

Q2W · « **Reply #43 on:** January 03, 2017, 07:41:50 am »

less than a month. Just use searchtempest.com. it's a search engine for craigslist.

All American · « **Reply #44 on:** January 03, 2017, 09:40:50 am »

Thanks
