So it's actually nice out today. Not too cold, sun is shining. Perfect opportunity for me to remove my CVT cover and check out whats going on in there. Pro tip: When removing kick starter, take the bolt out all the way. It won't come off unless you remove it completely. Figured that out after about 2 minutes of pulling. So yeah I had a rough start right out of the gate. Lmao. I'm such a noob. Alright well that was a stupid mistake... Onto the next step. I have a plastic cover between my kick starter and the casted CVT cover. Figured it would be a piece of cake. Boy, was I wrong. Stripped both of the d*mn screws right away. To who invented phillips head bolts -- I hope you choke. What a completely horrible idea these bolts are. I mean come on! Maybe it wouldn't be so bad if the bolts were made of something with at least some degree of strength! Ugh. OK. So, yeah, I probably didn't use a phillips head screw driver large enough... But I really don't know if it would have made much of a difference. Here are some pics of the damage. I put the kick starter back on and it's just sitting in my garage now.  I don't want to have to extract the screw with my EZ out, what if I break the extractor?! PS -- When I do get those f*%&ing bolts out, they won't be going back in. Nothing but stainless 8mm hex bolts from here on out -- The way it should be! imgur.com/jBBO7.jpgimgur.com/f5yCF.jpg |

I'll tell you what buddy, I had the EXACT same problem when I tore apart my RX8 during summer. And I used the biggest screwdriver I could find. I layed the bike completely over, put all of my weight on it, and had my brother help me twist the screwdriver and it STILL stripped them. I managed to get one out, but the other one got too stripped. I ended up clamping onto it with a vice grips and breaking the head off. You think those 2 screws are hard, you're in for a treat when you try to get the CVT cover off  All philips head screws, and most of them don't want to come out. Just a heads up. |

Vert - When you said Impact Driver I automatically assumed Impact Wrench. I've never seen one of those... What a great idea. Does it work well? I assume, as these screws are quite soft, it would embed nicely. I will be purchasing one tomorrow! Ive also picked up some penetrating lube spray. Do you have any reasons why I might not want to use this stuff? (Ruining plastics, etc.) Is there any amount of lock-tite applied in manufacturing?
Reign - Oh, geeze! You're depressing me, man! How did you get a vice grip on there? I thought about doing that, since I would be replacing the bolts anyhow. The only problem is that the outside face of the bolt sits nearly flush with the plastic. If this wasn't such a new scoot, I'd probably just cut the plastic piece off. I don't want to ruin anything I don't have to, though. Also, it says Yamaha on it. Lol, which if I sell, will definitely be one of my selling points to the potential buyer. "Man this is one quality scoot! Look, it's even got a real *cough*cloned*cough* Yamaha engine!" Just kidding, I wouldn't do that. I'm the worst liar in the world. And to think I wanted to be a lawyer!
So I'm assuming you both replaced all your phillips bolts with quality hex's? What material did you go with? Stainless steel? Hardened steel? Did you apply lock-tite on the new bolts when reassembling?
Thanks for the help, both of you.
Edit: I just had a another question, Vert. Would I be able to use a regular screw driver and a hammer to achieve the same affect? I have a Harbor Freight gift card so if not then I will be buying one. I've also got a friend that works there so I get 20% off everything in the store... Which is nice cause I lose and/or break all of my tools at one time or another. (I can't wait until I get my own place with my own garage!) The only problem is Harbor Freight is about 20 miles away and the only way to get there is on a 55mph speed limited road. I top out at 40mph right now. It's OK though, I have the hazard four way flasher feature. Mostly everyone gets in the other lane long before they reach me... Still unsettling.
Reign - What did your RX8 top out at stock unrestricted? Did you have to unrestrict yours? Did you ever weigh your stock weights? I'm dying to get into the CVT to see if I have the washer in my variator, and inspect my weak ass contra spring. I have the 2006 model, by the way.

The right bit for those screws is stubby with fatter fins on it. Instead of trying to find new screws you can cut a notch in the heads of the screws with a hacksaw so you can use a flat screwdriver on them. Impact driver with multiple tips: www.toolnet.co.za/images/47641.jpg |

jmstar50 - Thanks for the idea for getting them out. There is no way I'm putting those screws back in after I get them out, though. It's not even an option. Getting new bolts as soon as I get them out and find out the thread pitch and bolt size. I'm also thinking of replacing all the little green screws on all the plastics with some stainless steel 1/4" head hex bolts. Maybe not, might look kinda tacky.
Here is a list of the ways I'm going to attempt to remove the CVT cover bolts in order.
1. Impact Driver
2. Vice Grips directly on screw
3. Hacksaw and very large flat head screwdriver with vice grips attached
4. EZ Out extractor
5. Drilling out and rethreading
6. Shooting out the bolts with 7.62mm full metal jackets
7. Blowing the CVT cover off with C4
8. Crying myself to sleep and hoping it was just a bad dream when I wake up

Someone put those screws on way too tight. They just have to be snugged up. They have a rubber washer on them so they won't vibrate loose easily.
Those screws are specially made for the cover as you'll see once you finally get them out. I just looked and couldn't find any replacements. I suppose a regular bolt with a flat washer will work okay.

Here are a couple of hints on using that impact driver. For best results use at least a 1 lb dead blow hammer. If you don't have one, buy one. They are one of a mechanic's best friends.
When using your impact driver to remove screws make sure it is set to rotate in the ccw direction when downward pressure is applied to the tool. Select the phillips driver insert that gives the snuggest fit in the screw head. Place the tool in the screw and apply just a smidgen of torque in the ccw direction with your holding hand on the tool and deliver a good solid blow with the dead blow hammer. Always grip the impact driver tool very firmly and applying that little bit of torque takes any slack out of the rotating mechanism so the entire blow goes into turning the screw out.
Good luck!

I don't think PB Blaster or some other penetrating lube will be an issue. Don't know that it will help that much either, but as long as you don't have any vents where you may spray it on the belt or something, it shouldn't hurt.
I never had a plastic cover over my CVT covers. One still has those screws, the other just has holes where they were.
Looks like your other Qs were covered. Step gave you some good tips. I use a 2lb maul with my impact driver. A good impact driver will make life easier. I really don't think you'll replicate the impact driver with a regular screwdriver and a hammer.

Tritons and Triton clones dont come with that plastic cover. Only the RX8 does. And sorry to tell you, but RX8's are the only clones that come with philips screws too. I had some nice quality hex head screws on my CVT cover. And when I threw that black plastic cover over my CVT, I threw on some hex bolts to hold it on. I can't tell you what the RX8 got for speed, as I got it used and immediately tore it apart down to nothing. My Triton tops out at around 48 though, according to my bike speedo.

My Tritons have hex heads to hold the CVT cover on, but they still have those cheap phillips heads where the plastic cover would be.

I have fought with the phillips hesds also...Another tip- If you still cant get them out with an impact driver use a drillbit almost as big as the screw head and drill the head right off the screw. Then once you get the cover off you will have enough bolt left to "hopefully" get it out with some small vice grips or a small pair of good channel lock pliars. Sometimes this method is allot easier than drilling and tapping out new threads. Hope you get it all worked loose.
BTW- If you dont get them all its ok. You dont really NEED all the bolts in your cvt cover. Just make sure you get the "corners" of the cover bolted back tight and maybe a bolt in the middle.
I ride with only 5 or 6 in mine, works great!

I believe you are correct but if im not mistaken he also has the phillips heads bolts for the cover itself.
