So I have my very first Atc still. My dad gave it to me when I was very little (was brand new; one owner bike), and it has needed just two repairs over the approximately three decades: replace/repair pull-start.
Any ideas of some simple & not so simple mods/upgrades for this classic? I'd LOVE to swap the tranny for one with a real clutch, personally...possible??
I have a 2003 Kodiak 450 that i purchased a while back with around 300 hours on it. It has never ran right from the beginning. Initially i thought it was just a carburetor issue because it was all clogged up from sitting for months. It has been cleaned, rebuilt, and taken off probably about 10 times troubleshooting this problem. I have quadruple checked everything including float height ect and it is set correctly, the jets are also brand new, needle and seat have been pressure tested as well. So after all of that I am convinced that the carburetor is not the culprit. I have an issue where the idle is very choppy, almost as if it is misfiring with a rich condition on top of that. I can use a brand new plug and run the machine for just a few minutes and it will be a dry and and coated in black carbon build up. The exhaust also has a strong smell at idle. I had trouble restarting it when hot for a while, but i adjusted the valves and it seemed to solve that issue. They were both way out of tolerance (tight). The weird thing is, outside of idle it seems to run pretty well.
So with all that being said I have ruled out the carb/valves/compression and moved on to the ignition and this is where i have a few questions about factory specifications. I guess the main question I have is, how strict are these tolerances? And could them being off by this amount cause the issue I am having? Do all three of these parts really need to be replaced? I would like to know before I spend the money on these new parts, and it not fix my problem. Below I will list what the specs were in the service manual along with the reading i got. This is my first experience testing ignition components. I just found it odd that all 3 are out of spec according to the service manual.
Spark plug cap resistance: 10 kΩ at 20 °C (68 °F)
My Reading: 8.90 kΩ
Primary coil resistance: 0.18 ~ 0.28 Ω at 20 °C (68 °F)
My Reading: Fluctuated between 0.4 - 0.5 Ω
Secondary coil resistance: 6.32 ~ 9.48 kΩ at 20 °C (68 °F)
Reading was within the specified range.
Pickup coil resistance: 459 ~ 561 Ω at 20 °C (68 °F)
Reading was within specified range.
Rotor rotation direction sensing coil resistance: 0.085 ~ 0.105 Ω at 20 °C (68 °F)
My reading was 0.3 Ω
Here is what I have collected over the years and maybe it will help someone else.
There are so many and several are too large to upload as attachments, so see any thing you need just shoot me a PM and your email and I will get them on the way to you as fast as I can.

I'm curious what all the ladies ride on this site and why!
I ride a 2008 Yamaha Rhino 700. Just added a new roll cage, dual exhaust and some other things. Here are a few pics:
I chose the Rhino because my arms and wrists get way too tired on a quad. I haven't tried a bike, but, I don't think my coordination would be good enough to handle that!
I LOVE my Rhino though!!!!!!! It's the perfect machine for me.
So, how about you????

I just recently bought a 1994 Yamaha Timberwolf 4x4 from a buddy who had the wheeler sitting in his garage for 7 years. I got it home and fired it up pushed it out of the garage and tried to shift it and it wouldn't shift. First it would click like it was shifting, but the wheeler wouldn't move and when I hit the gas it revved up like I was in nuetral. After trying some more it became stuck in 1st gear and wouldnt shift at all. But it later broke loose agian and acts like it is in neutral again. I took the motor off the machine to make it easier to work on.After asking friends they were convinced it was a clutch problem but after opening up the casing for the clutch I don't see anything out of the ordinary and am concerned that it may be a transmission problem. Any help would be greatly appreciated thank you.

The Hop-Up: You may be saying to yourself, “that’s a chick bike,” and you’re right. But honestly, it’s so much more than that. It’s one badass bike. http://www.quadmagazine.com/quad/features/article/0,24942,1587044,00.html
Hi all, I try to find this manual in the threads but you have a lot of stock here
Cannot find this particular manual.
I found it for YFM200 but not sure if they are the same.
Thanks if you could help me with that.
Im new here so if I did something wrong, please tell me.
I have an 04 ltz and it started sputtering a little bit while going down the road and I was low on gas so I just figured that's what it was. But now I can't get it to start I completely cleaned the carberator put a new spark plug and coil pack in it and all it does is turn over. It has compression it's getting fuel and it is sparking but all it does is turn over any idea what it is??
