Flywheel Weight Question

9 posts in this topic

I purchased the GYT-2S297-50-50 Off-Road Flywheel for my 08 and it doesn't look at all like the one pictured on the Yamaha website( http://www.yamaha-motor.com/sport/products/modelscitemdetail/5/209/1218/5375/2008/1/4335/0/1/detail.aspx ). Was a little concerned when I ordered it because the description said that it was for an 06, but everything I read seemed to indicate that the part was the same for 06-09.

The part that I received looks like the one pictured in the manual and is stamped with "F2S210" and also "8YT". I also looked up the stock part number on Ron Ayers and it is listed as "2S2-85550-10-00" Any idea if this it the GYT-2S297-50-50 or is it possibly a stock replacement. Just want to make sure that I have the correct part before I tear the bike apart. Here is a link to what I ordered:

Any help is appreciated.

The GYT-2S297-50-50 is the correct weighted flywheel for your engine. It doesn't look like the picture because the picture is of an older flywheel for the '03-'05 models.

2S2-85550-10-00 is a stock flywheel, and not what you want.

Thanks for the quick response.

I was fairly sure that I ordered the correct part number, just not sure if what I received was the GYT-2S297-50-50. The number stamped on the part doesn't match the offroad part mumber or the stock part number which is confusing. Is there any way to verify that it is the GYT-2S297-50-50 visually, by weighing it, cross referencing the number stamped on it....

What was the number on the container the box was in? Numbers stamped on parts themselves are rarely useful except in identifying unfinished components at the factory.

Good point. Checked the box and the correct part number is listed and described as the 6.15 flywheel kit on the factory label. Thanks for your patience.

I doubt this played a role but right now the GYT-R off-road flywheel is on backorder according to the dealer I ordered from a week ago...

It took about a month to get mine. Did the swap this afternoon there is clearly a difference between the gytr and stock. Probably wont get a chance to ride it for a couple weeks, but sounds like it should make an improvement.

Odd, a few guys have said their waiting so I expected too as well but I got mine in a week and that was 2 weeks ago. Excellant results on my 08, could have been that way stock. Better low end characteristics and less stall prone.:crazy:
