Best bang for the buck

[Lvnspeed]

I am looking to do some MODs to my 2007 450 what are the best bang for the buck? I am looking for more HP and speed....

for HP, pipe, filter and rejet. For speed the cheapest thing you can do is change sprockets

[250r4life]

take the baffle out, take the lid off the air box, and install a pro-design filter...

and then re-jet...

and you can always retard the cam too, and you'll have a screamin deamon and will have only spent $150...

I like the cheep mods.....

is there a thread to the Cam retard mod?

[250r4life]

not on this site, but on YFZ central i think there is one...

just get a UNI filter that bolts right up for like 30 bucks, ditch the airbox lid and the baffle and rejet liek said before. this opens the bike up more than you can believe. the cam mod is also another way to bump up your ponies..

i dont know as how the cam mod ups your HP all that much, but it does make it wind out faster...

Where can I buy the a pro-design filter???? Can anyone tell me about where to rejet to?
