I am having a fantastic time changing my clutching on my 98 srx700, thanks for all the help. I would also like to change my stock gearing, the general consensus seems to be that the 98 srx700 was a little too tall (23/37). In 2000 the srx700 went to (23/3
. The problem I am having is the tech section on this site seems to spec the wrong chain for a 98 srx700. Yamaha motors (and a host of online dealers) show the chain for a 98srx700 to be a 68L. For the 98msrx700 the chain is a 70L. The tech section on this site lists the chains the other way around. Who is right?
What I really need to know is the yamaha part number for the 38T or 39T driven gear that will work with my chain. (I assume my chain is the 68L and the tech section on this site is wrong for the 98srx700)
I have yet to decide whether to go with 38T or 39T. I am leaning towards the 39T since a little over 100mph is fine with me. (My buddies ride f7's and the only time I can bet them is in 2000+ feet, I am damn close on shorter distances, and am hoping a little shorter gearing will help.
Thanks,
P.S.
I have stared at the gear page in the tech section (http://www.totallyamaha.com/snowmobiles/aaTECH/drivespecs/gear.htm) for hours on end, I find it hard to make sense of.
My sled has 10 000 miles on it, and I am WAY more reliable than my friends' Artic Cats.

I'm running 23/39 gears in my srx and I am using my original 70 link chain that I used with my 23/37 gears. The 39 gear that I got was from a 98 msrx. You should be able to find the part number of the gear by looking at a parts fiche for a 98 msrx.
make sure not to switch with the newer style gear from 2000-up they are not the same

How different do you find the 23/39 gears compared to the 23/37. How much top end do you lose, how much bottom and mid do you gain?sasksrx said:I'm running 23/39 gears in my srx and I am using my original 70 link chain that I used with my 23/37 gears.

Thanks for the reply, I guess yamaha's website (http://www.yamaha-motor.com/sport/parts/home.aspx) has it backwards. I have seen this happen before with more obvious errors in their microfiche. I will order the 39T driven gear (8DF-47587-90-00) and use my current chain.
Thanks.
Thanks.
Like MOD said, make sure its the 15 wide gear for a 1999 and older sledPauljones said:Thanks for the reply, I guess yamaha's website (http://www.yamaha-motor.com/sport/parts/home.aspx) has it backwards.
