Hey guys I am a experienced rider but j am not really into after market parts. So I was wondering if putting a bigger sprocket on the rear axle where the chain goes on. If getting a sprocket with more teeth would give me a higher top end. I usually ride with a YFZ450 and wr450. And I am not really worrying about my acceleration just more speed to stay with them. My dad does not want me putting judge upgrades into th bike so something smallnlike this could help me. But j am also into RC cars, and j know changing gears can make it over heat. So would over heating be a problem? Thanks for the help and if there is something that j can change that is not really a upgrade please tell me. Thanks again
 
most use a 14 tooth front sprocket for more speed,
more teeth on the front, or less on the rear = more speed

i think the 14t requires a longer chain though ?
i had to remove 2 links in my chain when returning to the 13t
 
If this helps, here is how I know it as.


When I raised, this is what I did (was a motorcycle)


the front sprocket, shows the biggest changes with a tooth change.

example. if you're stock sprocket is 13 teeth.

if you go to 14 teeth, you loose a little bit on the low end, but gain a little bit more on the top end.

and vise versa. drop a tooth on the front sprocket, see a little more low end, but loose a little on the top end.

I have always looked at the rear sprocket for mild changes, fine tuning I call it.

I always seen less of a impact adding a tooth or removing a tooth on the rear.

You still see changes, but they are much more seen with playing with the front sprockets.

I use to have like 4 different front sprockets and 4 different rear sprockets. Id play with. the good news. back then the front sprocket was only like $14 each for me. Well the rear on my motorcycle was much more costly.

I hat to say what the changes are for a blaster, but should be relatively the same type of senerio for the blaster.

and I was lucky, that I did not have to add length to my chain on my motorcycle.

But I have seen where you have to add a link or remove a link. and I do not recommend more than 2 links on a chain.

So if you were gonna have to add more than 2, get a longer chain.

Also if its your old stock chain. replacement is highly recommended.

1 tooth up on the front is equal to about 3 down on the back, and vice versa.
If you are running out of revs, gearing up will give more speed at the cost of acceleration.
If it is dieing for power in 6th, and most stock Blasters are, you will gain nothing sprocketing up.
You need more power to haul the gearing.

Buy a head off Ebay, have it sent to Ken O'Conner to be rechambered.
Even better if you could get him to rechamber it for running 2 basegaskets.
Your Blaster will fly, and you didn't even port the jug.
 
Okay this what i am thinking, i am going to buy a larger front sprocket a 14 and 15t. Along with this i am going to buy a new chain because mine is original. And hell i am taking it off anyway so might as well buy a new chain with the right amount of links.
 
To save problems in the future, spend that extra and replace the complete set, you wont be sorry.

The old rear sprocket may be worn just enough to ruin your new additions.
 
going up a tooth on the front does not require you to take links out of the chain. I didnt have to on mine anyways. the chain tension adjustment gives a good bit of room to play with if your toying with gears without chainging chain sizes. but im sure if you would go to a big change like a 12 45 you would need to add some links. (thats just an example)
