Plus you're giving them a lifelong skill. Teaching truly is a noble profession.

Hey Back2TX,
If your asking how well the XT's do in the heat, they do fine. Make sure your not running too lean and all will be well. We are just now hitting 100+ degree days. This time last year we had 45 or so 100+ days already. Riders have more of an issue with the heat than the bikes do.

Welcome back to Tejas, pretty senoritas and endless Mexican food await...

3 XT350's

I just found this thread and wanted to introduce myself. I have recently purchased 3 XT350's (2 1996's and 1 1987). They are going to Liberia, West Africa but I want to do as much as possible to take care of any problems before they go.

So I hope to read through this entire thread and then come back for any additional quesions.

Thanks in advance for your help.

As I mentioned before, I bought an XT350 for my dad to ride.
He is 66 and not in the best health, but its light enough he can get out and ride. Occasionally with me on the LC4.
Then I'll take off on the little XT and it does all you ask of it. The 6 speed is wonderful.
Its been making me rethink the LC4 as the bike I want to keep.
Now I'm second guessing the LC4 and thinking maybe a TT350 with lights would be a better choice as a swiss army knife type of bike.

Cylinder bottom gasket

My bike is now drooling oil from the bottom end of the cylinder head.
I had cut a gasket myself for it from klingeride sheet but i guess it was too weak.
Original was metal gasket as i see from the parts list but it was absent when i first opened the engine.

I ordered a new gasket from ebay. Untill that, i need the size of the O-Ring there. You can see it as No:5 below link
Is there someone could measure it for me?

Best wishes

SKY

Stator re-winding

Hi All!

Due to some charging problems i decided to work on alternator of my bike.
That way it would be a nice opportunity to learn the details about it.

The XT350 electrical system has two coils for charging, one for ignition and a small pickup coil to trigger the ignition.

The charging coils has branch from the middle of the coils which feeds the main lightning directly with AC voltage before being rectified(turn to DC) and regulated.
I guess this is for avoiding loss of power while rectifying.

The main cables from coils goes to reg/rect. unit which charges the battery, feeds the turn signals, park and stop lights.

There are some measurements below:

The wire diameter of the coils: 0.85mm (19/20 AWG)
Number of turns: 320
Number of turns side to side of the coil in each layer: 40 (38mm wide)
Number of layers: 8
Coil body height and width: 8mm x 23mm
Length of wire wound aroun each coil: 26 meters
The branch for main lightning is located at: 9 meters(or 17meters)
The number of turns after and before the branch: 97 / 224
The total resistance of each coil 1,7 ohms

I also attached the flywheel to a milling machine and made some more measurements while turning at 3000 rpm

I will name the ends of the coils as GND - MID- END
MID end is the branch between two main ends of the coils.

(all AC, open circuit measurements)
MID-END: 25V - 9A
GND-MID: 11V - 4A
GND-END: 35V - 3A

I made tons of measurements with different number of turns and different
diameter wires.. but couldn't get any significant output.

I tried 1mm wire but the clearance between magnets and the coil was very narrow, it scratched.
Less number of turns cleared but the voltage dropped a lot.


The last setup was with 0,95mm wire. (18/19 AWG)
300 turns, 8 layers, 30V, 3.7A

After satisfied the last results, i started to make measurements with the reg/rect. unit. At that point i found out that the unit was malfunctioning.

I went out and bought a china made cheap reg/rect. unit for 10 usd.
It worked like heavens.

I have 14 volts at idle.
When all the lights on, the voltage stays well over 12 volts at idle
and around 13 volts at mid. RPMs. I got more than 100Watts

I will keep you informed as soon as i got more detailed measurements

Best wishes,

SKY

Did you just bend up you're own midpipe?

Need some advice on this bike...

Can anyone give me some advice on this bike? Potentially going to buy it this weekend.

http://richmond.craigslist.org/mcy/1873888491.html

The following has been done in the last year:
-seat cover
-fork seals and gators with complete fork internal cleaning and new oil
-tires and tubes
-valves checked
-valve cover gasket replaced
-new sealed wheel bearings
-used supertrapp exhaust added to replace stock exhaust
-Brake fluid flushed and Oil changed (couple of times)

What do you think?

We've got plenty of those kind too. What part of the state are you moving too? I'm central, holler if ya wanna ride sometime.

SKI, glad to see ya digging into the stator. What was the original output of the stator? I'm curious to see how much you've improved it.

Falcon,
The price seems right. The Supertrapp is a good upgrade, the airbox needs to be opened up and the jetting adjusted to make it run right. Make sure it's not running too lean (check the tip of the exhaust, also pull the plug and check for color) There's been a bunch on this in this thread to look at. Once all that's set it'll run like crazy. Otherwise typical "new to me" moto stuff, make sure it shifts thru all gears easily etc.....

Tough bikes all around, hard to kill, cheap parts, not lots of aftermarket support but lots of fun to ride.
