removing the air box lid

[blasterkiidirl]

i know this probably get asked a lot but will it make much of a difference taking it off and putting a twin-airfilter a k&n pre-charger on aslo how much should i pay for a good ex400 rear shock

 

[blasterkiidirl]

i know i will also have to rejet

 

[blaster racer87]

idk about the filter stuff , but for a shock around 60-90 bucks depending on condition.

 

[Blaner]

should be pretty reasonable for you, using UK monies... yes, take the lid off, and rejet...nice improvement...

 

[blasterkiidirl]

i dont care about cost but will i feel a an improvement out on the track my blaster is stock power wise

 

[blaster racer87]

yeah 400ex shocks are better than stock. the blaster stock shocks are horrible.

i was talking about the air box not the shock :L how much is a good ex400 shock wort

 

[blaster racer87]

lol didn't see the power wise part. a good one about 80 used ebay

 

[Blasterr525]

Well 80 is a lil high for me. Look for a z400 rear shock also. Same shock, different quad. would look for 50-60 US dollars or IDK what european monies are worth. And yes the airbox lid delete will need a higher jet to give some company to more air coming in to your Yamaha Yfs200rr Blaster Atv Carburetor.
Or anohter recomendation is upgrading to a new carb(YZ85, KX85, Rm85, CR85) and a Outerwears lid cover.

i run a K&N filter with the lid off, made it seem alot more snappier and could feel more power, not much, but some. also it sounds alot louder and meaner with the lid off lol, but make sure to re jet

You will certainly feel a power increase with no lid / vents. I run vents. Up the jets a few sizes and you'll be set.

As far as shocks... the 400ex are very common to upgrade. If you do, buy Ken Oconner's bushings. Make them fit perfect.

will that take some of the low end on a stock blaster

 

[blasterbuddy200]

for me it made it have a little more low end, but i felt i lost a little top end though

does still have the same size and features

 

[Blaner]

i believe the features are the same, the shock is the same part. whip off the lid, i promise you its better, i noticed much better bottom end grunt when i first did it. sounds much better too!

 

[Blasterr525]

yes still same length and features my friend. And i did not lose low end for mine? i though it bumped it up few power bands

 

[blasterkiidirl]

can u remove the spring on a z400 rear shock

 

[00blaster200]

if you race and only ride on a track i would run a kn filter with outerwear.
