I just got a new kfx 450 and its great but it feels like there is no second gear right after i shift from first it seems like i have to **** in a sec into 3rd. what can I do about this or is this just because I haven't broken it in yet I only have like 20 min on the bike.

 

15tooth front sprocket will take care of that...

 

what are the stock teeths on these gears? (front/back)

 

14 front 38 rear stock

 

Will the 15 tooth front still give me the low and mid range the stock has ? And how much change will the 15 tooth give me cause i really don't want to lose any low end but i do find myself trying to find another gear when I'm riding around

 

and will i have to change my chain if i get the 15 tooth

 

how hard is it to change the rear sprocket too?

 

take the wheels off, loosen the chain, and most likely the skid plate (chain side) off. Then loosen the sprocket up so it will slide off.

It's prolly about a good hour of work depending on if you've wrenched on them before. Shouldn't be too bad.

lossen all 4 swing arm bolt's that hold the carrier in, use the spaner wrench which ya got w/ your quad, to lossen the chain adjuster,



lossen the sprocket bolts, then remove the wheel....

Umm you just have to take the chain side wheel off....I did not have to mess w/ the skid.

There's link lock sprocket's now which come in 2 piece's, get 1 of those & there's know messin around w/ taken the wheel's off....

I run 15/34......but I like to go fast......

 

Thanks for the pics and the advice I will prolly end up changing both .
