WOW I haven't been on these forums for awhile, the crap you miss while being gone. After reading these posts I will be getting the Yamaha fired up on the trailer and checking for this noise. I have an 07 with less then 1500miles on it so I will be Peeed if my sled has the noise and the dealer...

Has any had a belt squeal at idle? I just turned 370 on the ODO and my belt squeals sometimes at idle. I had to take it easy this past weekend having had my son riding with me. A lot of of the riding was mid RPM range I wonder if not getting the sled into the high RPM range and gear range is...

Yes buy it. I paid more for my 07 Vector GT then that but it was early season. That is a really good deal. Jeff

My question is have you checked the plugs since doing so? I know soemtimes when decreasing back pressure you can lean the fuel mixture out some. I would also like to hear a sound clip. I am thinking of doing the same thing but I don't want to be to loud. If it sounds like my bike with a Two...

You haven't went to that site yet have you? Mainly it is about not babing the engine during break in since the most important part of the break in is making sure the whole ring seals to the cylinder walls. The Yamaha snowmobile breakin instructions is almost exactly like the motorcycle...

I used the link The Snow D.O. posted to break in my sled. I have used that way to break in my last two sports bikes (both yamaha R1s). My bikes always seem to dyno with higher HP and TQ numbers then my freinds that follow the owners manuals. I also ran my sled 200 miles ( which was my first...

This is all great information being a 200 lbs rider. I have used rachet straps before when removing and installing rear springs on cars. So did you use the procedure above of just dropping the rear half of the suspension to get to the spring? I would guess the overlap goes to the 4th...

Isn't the 06 GT a mono shock? I didn't know that the spring seat had a C clip adjustment also. I am running my spring at 7 but I adjusted the shock compression to help with bottoming out. With gear I weigh about 215. I only bottomed out once this season and I have rode some bad trails. Which...

I have noticed it is heavier then other sleds I have riden. It doesn't bother me but I let my wife ride it all last weekend and it took her hand three days to feel better. That was only after 130 miles I imagine the throttle will lose tension as the sled gets broke in more. With only 200 miles...

I start cranking my sled while pushing the choke out. Usually about half choke it fires and I just back it off by how it sounds. I have notcied I need to give my sled some gas at times after fuel station fill ups. Anyone else have to does this. I'm wondering if stepping the idle up will help...

My 07 Vector GT has the stiff as a board Flap and is angled back a lot more then my freinds 05 Rage. So it may have been a factor in crinkling the tunnels. I do believe tighting the tail of the sled down so the shock is bottomed out could cause this too. Anyone that has ever hauled a motorcycle...

You still have to sync EFI snowmobiles and motorcycles. Also if a snowmobile EFI is the same as a motorcycles EFI it uses the same map that has to be reprogrammed to make changes for weather and conditions to get MAX power. The same as a carb rejetting. In other words the map is a controlled...

I have a great article from one of my Motorcycle mags about Snell verus DOT rated helmets. After reading and checking out their test results I switch from a high dollar snell rated one to good named DOT rated helmet. In all it made the point that Snell helmets are too hard and don't absorb...

Since I like to fabricate my own stuff I made my own skid plate. I don't care for the plate to wrap into the front nose piece so I kept under the front plastic. Jeff

Yeah I know that I trying to make the point that a wet friction plate system was not being used. After rereading it I fixed it up to better make my point. The system is a sprag type clutch system that uses a bunch of parts that are important to have friction additives but not as important as if...

One more pic while I am at it. Jeff

You could get away with running normal Car type oils in these engines. (i wouldn't) The friction additives are important in vehicles with a wet plates clutch system. Yamaha usually puts on there Yamalube bottles whether it contains a anti-friction additive or not. I checked the fiche images on...

Haven't had a chance to try out my 07 wheels but once I do I will give reports back if there are any problems. Since it is a known problem and Yamaha like to be known for quality and don't like the cost of fixing them I would say they are of better quality. Jeff

RVP=Reid Vapor Pressure There is different RVP ratings for fuel used in cold temps. Where I work we put cars in cold chambers and anything -20 or below we have to drain the fuel and install fuel with higher RVP ratings to insure the vehicle starts. Usually gas companys change this when...

Bone stock hasn't even seen a trail yet. I hope we get a chance to change that weekend. Jeff
