I have a stock Blaster what mods should I start with to keep bottom end power. It is for a 13 yr old for woods riding.

Thanks

 

If you want to keep the bottom end power or even increase it

keep the stock pipe
Find a lighter piston (Wiseco pro-lite)
have the squish band leveled and take .030" off the head
remove the air box lid
add a K&N air filter and outerwear
aftermarket reeds (boyesen power reeds are ok for bottom end but not the best or for top end)
NGK BR8EVX , EV or ES plug
reed spacer
re-jet the carb

This will help it rev quicker, and give it a few more HP down low in the rpm range.

 

also add a toomey pipe to that, get the toomey b-1 pipe kit and that will get you a filter and jets header and silencer. you will lose like 1-2 hp in the really really low rpms but then it jumps up so you wont even be able to tell you lost it unless your juss putting around or something. they are really good pipes. I have the FMF but i cant tell you the diff from the stocks cuz i have never ridden a stock one i bought mine with the fmfs on so. toomeys are good though!!

 

start with a toomey pipe kit then go on to what hardly dangourous said

 

oh ya and you could widen it and legthen it
flip the front wheels
get some new tires and wheels the back ones suck
mine have a 3 inch offset so that widens out the back
if you really want to go the good route tho (but expensive) get new aarms and axle
also you can get an swinarm extention or whole new swingarm

 

Yeah the toomey pipe is about the best you can get for overall power. I just s\aid keep it stock because it is the best low end pipe, But the Toomey gives up to 7hp over stock higher in the rpm range.
if loe rev power is what you want the stockmpipe does have 2-3 HP more but once you get to about 4000rpm the toomey dumps out a lot more HP

 

ya i see that your saying

 

More Compression is the easiest way to get more low end....i open the air box up to(that added a lot of mid/low),i would get a toomey pipe anyway,after i took of the air lid it feels not noticibly weaker on the bottom end!
