| I am looking for some info. on how to install cams? I know the engine mechanical part I just really need to know how to raise the front frame from the rear. I do not want to cause some unnecessary damage by forgetting to unhook something or such. I pulled the bolts to the bracket that attaches the frames together but it looks like I need to unhook the tbody in the front frame and maybe pull one of the front bolts so the front can pivot?
Thanks for any help, Dwight |

Rancho Cucamonga, CA | The front will pivot without loosening anything up front. You will need to use a prybar by the rear bolt to lift it high enough, then slide a screwdriver through the holes to keep it up. You will still need some modified allen wrenches to get the cam covers off, very little room. I wish I took pics when I did mine. |

| Do I need to loosen anything for the tbody or is that just a rubber seal? |

| Dwight, I have to chime in here. I am not trying to step on any toes but if you are to move that frame up without removing the bolts to the throttle body then you will for sure have a vacuum leak after!!!!! The 08 and 09 have a weak vulcanizing to the adapter plate and are prone to leak. I would even change it if I were you since you are going to have it that far($65). The new plates have a different number and also look different than the original one. Just think about this, you are going to move the frame up at least one inch. Do you think the adapter plate will stretch. If you choose not to remove the bolts watch for a leak after. The way to tell if you gained a vac leak after is it will have a high idle for a length of time until the bike is totally warmed up, about 1500 to 2200 RPM who knows you may have a leak already. It should idle at about 1100-1300 RPM for no more than 30 secconds than drop to 700-900 depending on the temps outside. I have a reference to this subject in the Tech part of the forum http://www.vision-riders.com/bb/forums/thread-view.asp?tid=11363&po... . I have pictures in the tech ref, hopes this helps.

| Thanks Dain for the info. I will take a look this weekend and see if it is already torn. |

| The way to tell is take some carb cleaner and start the bike. As soon as you start the bike spray the cleaner around the thottle body where the bolts go in and if the idle drops real quick then you have a leak.

| The throttle body and adapter plate are bolted to the adapter in the air box that is in the frame( http://parts.polarisind.com/Assemblies.asp part 12 under fuel system, fuel tank). When you tilt the frame to the front it pulls on the adapter plate. I am not saying they crack but the vulcanizing will come loose. No I have not done 200 cams on bikes but I know my sh!t and for 4 little bolts I would take them out before I tilt the frame, thats just me. Like I said in my first post I am not trying to step on any toes so dont take this the wrong way please. I have rebuilt 6 Visions and have had them completely apart and have seen this happen to more than a few. I hope it works well for you Dwight and hope you dont have any trouble. But if after you get a high idle you will know why.

| I also have a timing wheel from LLoydz and was wondering what the advance is that I should set it at...4 degrees? |

That is a good general starting point. For most it stays set there.

| Thanks Rylan, due to the lack of a dyno in my general area would it be wise to set at maybe 2 or 3 just to be safe? |

No, your bike will tell you if you've gone too far. Some bikes will take 6+, others only 2. Give it the most it'll take to get your moneys worth IMHO. |

| What does it do if it is too much, I know detonation can happen but you usually notice that when you are a heavy load...any other symptoms I should see. |

That's it - it'll ping under load. Advance until it pings then back off a degree. |
