I put it on last night. Unfortunately I will need to take out a link. Definately to much slack! Oh well! I know I will lose top end too but oh well. Most races I do are with friends who have faster bikes anyway. At least I'll start much quicker

 

You shouldnt have to take out a link. Just adjust the chain.

 

were the stock sprockets worn out? if they were, then get a new chain and rear sproket while your at it. new sprockets with an old chain will wear out faster. good luck.

 

I did have to take out on link on my chain. I took it off & put my chain back on. Got it all adjusted & took it out in the yard to mess around. I could definately tell a difference. I ran thru the gears much quicker. My buddies & I have been working on a track. I'm hoping it will get our times a bit closer. My friend on his yfz450 has me by about 5 seconds a lap. He is definately a better rider though. I think I'll close the gap a bit this weekend. I'll also get back on to let you know how much difference I really notice

 

yea i dont really see people with 13 tooth, mostley see them on like the 416 440's. so i really think your losing money and power, i woulda got a 14 tooth.

 

Yes a 14tooth would be better. Especially on a stock ex.

 

When adjusting your chain how do you tell how tight to put it?

 

A 14 tooth is a possiblility too! I just need to ride with someone to really see how much difference there is. I can tell a difference no doubt. I can't tell how much top end I lost. I also can't tell how much quicker I'll be off the line. I'm curious to see how it does on the hills too. I'm not that concerned with losing topend at this point. I will be upgrading to a 416 or a 440 this summer! That or the stars will align & I'll get the new 450r. I'd definately prefer the later

 

how is that possible.? all youir doing is taking away one tooth from the equation?
