Yamaha Grizzly 450 - spark plug replacement

Автокөліктер мен көлік құралдары

The first of a number of service related workshop tasks on a 2014 Yamaha Grizzly 450 ATV. In this video I show you the correct procedure on replacing the spark plug.
In the video I cover checking & setting the plug gap, tightening torque & also a couple of tips & tricks that make the job a little easier too...
I have also included a chart showing what the colour of the spark plug electrode means in relationship to the engine's running - a simple and really useful way to check the condition/tune of your engine.
Any questions or comments just leave them blow and I'll do my best to get back to you shortly...
Andy Mechanic!

    Best tips to start a quad in cold weather 0 degrees etc ? Having a hard time even with battery topped off tendered. I think maybe I need new plug although it eh s fairly well. It is kind of hard to start in non cold weather. I have to throttle it and play with throttle while choke is engaged. Or it will die. Once she warms up it will idle in choke with no throttle

    I have a 2006 Yamaha 450cc and it only goes 25 mph with a load if I jack it up it goes up to 54 mph can this be the spark plug?

    Hi, Yes, sorry, I did reply to his but it seems it has gone? Anyway, yes, 20Nm is just fine for your bike if that's what it states in the workshop manual. It is different for each make & model of bike. Hope this is of help. Cheers Andy

    NGK plugs don’t need anti seize on them from the factory they use a coating on there to prevent problems. Actually there is TSB on the website. But cooper paste is still good to use.

    We have a very neglected 2007 Grizzly 450. Yesterday, changed oil and filter, and coolant, which wasn't in too bad of shape. The quad has been hard to keep started, have to warm up with choke in position 1 and warm it up there quite awhile before it won't quit when you close it down to 4. I bought a fresh spark plug and went to change it out today and found oil on the plug! I'm green as you can get so don't know what to do next!

    Oh dear.....sounds like the bore may be worn letting engine oil into the combustion chamber. Just check all the engine breathers aren't blocked first, then do a compression test... Also, you may want to pull the carb off & give the jets a good clean out too... Good Luck. Cheers Andy

    I am in the process of changing out my spark plug. I have a new one in the package and gapped correctly. Unfortunatley, when I pulled the cap off something was left on the tip of the spark plug. It looked like a connector from the boot. I think I may have to replace the boot. Can I just replace the boot or do I have to replace the whole coil wire and coil? I can't seem to disconnect the wire from the coil and I don't want to tug too hard.

    Ah okay. The coil lead is bonded to the coil so don't try remove as you'll break it. The plug cap has a screw thread that goes down inside the HT lead so if you hols the cable and rotate the cap anti-clockwise it should come off. make sure you replace with the correct ohm rated plug cap! Specs in the Service Manual Hope this helps Andy

    Oh 6000km is low, most of the ATVs here in NZ will rack up 20 to 30,000km without major issue provided they are serviced every 1,500km. Cheers Andy

    The clutch is not in the CVT, its behind the primary (engine sheave) - it runs in oil & also houses the one way or sprag bearing that provides engine braking You have to remove both sheaves & the rear plastic CVT cover to gain access to the aluminum cover. Oh & the nut that retains the carrier to the end of the crank shaft is left hand thread Good luck Cheers Andy

    You skipped over the part I needed to see and then never even showed a shot of how much plastic you had to remove to access the Plug. I need to know how to get down to the spark plug. Any 10 yr old can change a plug. it's disassembly part that's hard.

    You can get to the plug without removing any plastics. Not all 10 year olds can replace a spark plug correctly... Andy
