I am new to this form and to ATV's and was wondering what all can be done to make a fast yet reliable blaster. I have already read the i should change the pipe, port and head work. I was wondering If I were to get a pipe, p&p, mill the head .020 if that would be good relaible power. Also with these mods is there anything else like carb,jets,reeds, etc.. I am not looking for a all out monster just maybe being able to keep up with my brothers stock honda 400ex
Reliable performance.

As long as you keep it maintained, you shouldn't have any problems with it. The mods you listed would be just fine, it's when you start really getting down to engine work when you have to start worrying about the long term. I've heard several opinions that going up to the 240 kit that you've undoubtedly heard about is not worth it for a typical trail rider, and is more for the more competitive rider with a enough stashed away to write a check here and there to cover the expenses. When you hear enough of the cons, you accept the fact that it may not be the best thing depending on your style. Another no no I've researched pretty extensively would be the stroker crank. 'Ticking time-bomb' was the term repeatedly used when I was asking about it.
My Blaster went over 18 years before I had to overhaul the engine. Just got it all back together last Saturday and am still in the process of breaking it in. Until my recent work, all I ever had to do was change the oil, keep the 2-stroke reserve clean, and maintain the air filter. Even then, I got pretty neglectful at times. :">
Well I don't know a whole lot about what mods to do yet, but I can tell you that you might stand a chance against your bro because my blaster running with a compression of 75psi (which is close to half of what the compression was supposed to be) spanked my friends 300ex. I don't know how much faster the 400ex is but just a thought....
Haha yeah these little engines are beasts in their own way. When I shattered the piston out on the trail, I had no idea what happened so I just rode back, and I was still faster than my two friend's 03 and 04 blasters. Couldn't tell you why, but when we realized the damage I'd done, it's pretty funny.
Wow thats cool! Yeah I rode mine for like a week before I even knew it was low on compression!
Me either, but no, I rode it back about 12 miles before I ran out of gas. You shoulda seen the crank bearings...
What if it was cracked and then fell apart when he removed it? Maybe? Well I know when I pulled my piston it had pretty much no rings left at all and it still ran decent.
The rings on mine were still intact, it was the skirt the broke off. I ended up paying a shop over $600 to weld part of the inside of the case and rebuild the crank. The piece the broke off got forced around the crankshaft as I was riding it and tore up pretty much everything.
That's why in your thread, SR Powered 240, they're recommending trying to flush out any metal bits from the bottom end of yours cuz you don't want those ring bits to get broken up any more than they are already, if they haven't been pushed out through the exhaust.
hahah you thought you had it bad?
Dude, i was riding on a shattered piston one time. I was rippin sh*t alll day long, and then all of a sudden it started coughin and spittin, so i rode it home full throttle and i get in the trail in my back yard 1st braap 2nd braaaaaap 3rd catung! mad loud i was like sh*t that aint good. Shattered it so bad metal chunks got enlodged in the crank of course, as well as in my cases, physically in my cases, and in a transmission gear. 1700 dollars later BRAAP BRAAP, im ripping sh*t again.

same sh*t happened to me! i rode mine for about 4 hours on a deteriorating piston. then she just shat. she'd run but only about 10mph at full throttle. pulled the top end and the piston skirt on the exhaust side was completely torn up!
def rebuild the bottom end, cuz, though most of my skirt went right out the exhaust, it def found lotsa little bits of metal in the crank bearings and rod bearing.
