i have a moded 300ex and i very close to beating 400 i still need a cam, 330ex kit, highier cpr piston, values and springs.stock to stock the blaster is close to the 300ex but a highly moded blastier can keep up with banshees and 450s so i see beating a stock 300ex will be alot easyier then the blastier.
the reed i see giving you a lot more power the a lightier fly wheel ,bored carb, and a polish for its price.

 

true sorry i didnt relize that that kit ran off of race fuel.....id think maybe u could get a diffrent head and get a biger pistonand get a diffrent carb and pipe.......im not sure if u could do that or not maybe if u could find a topend off of a 400 tb and the piston....if they bolt up the same im sure that would give u better power and speed.....now u might want to have some one dubble check what i have said and see if it could be dun

 

I think i know what ur saying.. Try and replace the stock head with a 400 one?


Well all the motor work i have done is basically whats listed in my sig, and i rebuilt the top end.. and i put a wiseco piston on it..



Basically im willing to do anything that i dont need racing fuel...


If az bad boys website would work , i would try and get some prices but i can never find it..


Maybe ill do the conversion kit and boerd carb?


and wait on the p&p (port and polish)


Or if the reeds are more than 600$ ill get hte other stuff...


Anyone know the stock speed of a trailblazer? i was told 45?


When i get through with mine i wanna push 65? is it possible? lol

 

its about 45 to 50 depending on what u have dun and how warm it is on the day ur running but i have had mine runnin at about 53 with the sprocs changed i think if u could just find the head and cylinder off a 400 and just swap them out and just keep them in case u want to sell it u have the parts to show the person what u have dun

 

I am looking on ebay but nothing for a 400tb... Im going to save up some money and im already at half (300 (looking to save like 650) so not really sure if i want the reed conversion kit or not.. If i dont get the conversion kit , i can save like 150+ , so i can do more cosmetic things, my dream is to have my frame powder coated a cherry red.... But that will prob be a load of money... If anyone knows from experience , if the reed conversion kit will give me more spped, or if the other items will please lmk thanks

 

the conversion kit will give u more power and speed for sure>......(id think anyway)

 

So u think its worth the 600$ rather than the other parts?

 

i think so but mi self im gonna sell mine and get mi sled fixed over the summer and sell that and buy a bigger 4x4 i want to get a sportman or a scammy

 

Well right now a new quad is not in my book, i rather spend 600-700$ on parts then get a new quad.. because i need other things like a car!



So still even though everyone says the reeds are better im still iffy about spending the 600$..


Does anyone do it besides az bad boy

 

The best power upgrade you can do to the 250 other than pipe/clutch is porting and reed conversion. If you do these you will smoke the 300ex. I had a highly moded 250 a few years back and it would smoke piped 400's. If you do the reed conversion you should do the porting as well while they have the jug. With these mods you will double the hp of the 250.
