Just grind off a tooth so there is a bigger space where the old tooth was ? Grind it right down to the radius of the pickup ? Interesting. Anyone else try this with simliar results ? Thanks for the info.

So, these high mph readings could be lack of traction ? Get the power to the ground and it might be more accurate..... :o|

I've been seeing these posts of guys reading 128 MPH or so on the speedo and only seeing 108 on the GPS. 20 MPH off ??? That's a lot to be off. I just find it hard to believe that Yamaha can't come up with a more accurate speedo. The Rx-1's had this problem too, correct? Is there anything...

I've got about 30 miles on it and have given it minimal wot bursts up to 10,500. This thing rocks !!! My arms are 2 inches longer now. ;)!

Weight Transfer Where you playing with the transfer rod or is that the stock setting ? very cool.

I also noticed how cool it was running. I was really ripping into it, would bring it to a idle and was surprised how cool the heat exchangers were. I was thinking of putting a rear exchanger on it, but don't know if I'll need it.

How many miles does the Apex/RX-1 engine usually need before it is turning 10k ~ 10,500 rpms ? Few hundred ? On a side note, I got to put some miles on my GT today. OMG !! Wild, awesome, wicked, intense, love it. I was concerned about going to a 4 stroke, no more concerns. This...

I was commenting on the link that Welterracer posted about the 124mph F7. wasn't bashing your post. ;)!

I found it to be a bit far fetched myself. But you never know what kind of extra ponies that crisp clean Canadian air can do for an engine.... HAAAA !!!! good one. :moon:

Thanks !!

So, I'm thinking about putting a skidplate on my Apex GT. When doing an oil change, there is a plate to remove under the engine to drain some of the oil out of the engine, correct? So, the skidplate has to come off with every oil change. Do the skidplates bolt in or are they pop riveted into...

Do these sleds sound awesome or what ??!!! That's some great stuff. Can't wait to get some snow here in Mass. Great info and vids. Thanks :Rockon:

speedo I'll curious to see how far off the speedo is on the Apex's. I'm hoping it's more accurate than the RX's, just hafta wait and see. thanks for the report.

Just wanted to say Thanks to all the people that are taking the time to post those great reports on all the new Apex's. Great information and keep 'em coming !!! :Rockon:

Is the timing retarded until it reaches a certain time period or mileage? dunno.

Good report. Thanks !!!

Yes, more info please. How is the handling, power, excelleration...?? you lucky SOB !!! :4STroke:

Thanks Moose.

First off, not only is this site a plethora of information, but it also hosts many members that have very good advice. Everyone here cares very deeply about the snowmobiling sport and no one wants to see any more trails get closed because of noisy exhaust. I don't think anyone is getting...

Sounds fine stock These sleds sound absolutely awesome with the stock exhaust. Why is the a need to make more noise? Your HP gains, if any, will be minimal.
