timing keys

[ratboy]

is the curtis sparks timing advance key woth a s---t. and can you feel a difference

[Martin Blair]

yes a big difference on low end, if you woods race it helps alot, it does take away some top end hp but not alot, adn it adds alot of low end. for the 15 its worth it.

Yeah I agree for the money you can't go wrong

[Silverfox@C&DRacing]

For the money they are a good investment especially on a stock bike. It will give you a more crisp throttle response
