help?? please

shut up, you took what i said wrong, using a full 125 takes years, absolute years to do, neither gscx or myself could do it, im sure you probably thought i meant in a straight line or something. but come back when you can argue and reason like a real adult, instead of trying to look cool by emphasizing how angry you are. im not going to resort to personal attacks, because im not stooping to your level, but in my eyes your blaster looks like sh*t also. but thats just my opinion, im sure someone on here thinks otherwise.
oh, and this bike will blow your sh*t away, thats a fact.

as far as the op, no, i am simply saying that 170 psi is manageable at numbers less than 100 octane. being a blaster motor or a crf250 motor has nothing to do with that. thats all im saying.

buy YOU need to calm down and comprehend what i say thoroughly

firstly, i can tell you right now id dust that old piece of sh*t in a second. and secondly, someone on here thinks otherwise? ive already had most of the regulars on this forum comend me on the work i did and how nice it is. you pissed me off so i said how much of an eye sore that pipe is.

oh, and you sure hurt my feelings because you dont like the pipe on the bike im about to sell :( that is their opinion about your blaster being nice, while it is clean and full of potential, its not my style.
thats why i use words like "that just my opinion"
and no sir, you certainly would not come close to this bike. while im definitely not biased towards it because im selling it, your blaster would be gone.
dont be mad because you didnt understand what i said, but for future reference, using a full whatever, means being able to keep it pinned throughout an entire professional mx track. i will not hold it to you for not knowing that, since you arent into motocross, but there was no need to be such a biotch about it
 
i know its not my fight,but come on,for the love of God 89,learn to f*cking disagree with people, you dont need to go and startbitchin because you odnt agree,jsut say a simple "in my point of view i disagree,a nd bla bla" this is you "hey you dumbass, learn to f*cking ride", wtf man, im not taking tj's side or anybody, im juSt saying that you need to learn to be mature! LET ME TYPE THIS IN CAPS SO EVERYONE CAN READ : THIS IS MY OPINION. ok so please dont come to me saying "hey Fock you man". AND LETS KEEP IT ON TOPIC! As for the blaster,if your really concerned,listen to your friend,he own a shop so he knows what hes doing.
 
thank you dareal blaster,
btw, 89, you really need to comprehend what you say yourself also.
"my blaster will dust that OLD piece of sh*t anyday"
while your blaster is 5 years older than my bike
 
u guys need to grow up a lil and stop fighting on the internet. to the op a 100 octane gas seems more than fine for the bike. rule of thumb for octane is u wanna use the lowest possible before u get pinging or detonation. simply raising octane can hurt ur motor. as in a dif. between a blaster motor and a car 170 psi is not a lot of compression. maybe in blaster its a lot and someone can steer u in a better direction but we race hondas and my motor is over 300psi in all 4 cylinders and im tuned on 93 octane. to the op ide try the colder plug and also how does urplug look? wat r u jetted at? do u have a adjustable timing plateon the bike b/c it may be advanced and u may wanna retard the timing a bit. if the octane concerns u ide get a new plug and a gallon of 110 octane and run it and see hoe it runs. could possibly be fuel or not but i cant see y it would only be in 5th and 6th gear if it was fuel.
 
ok update. the guy at the shop seems to think it is piston chatter. he is suggesting to check the timing as well as the jetting.. he tells me a colder plug is not the fix. and the gas im running should be good. he really seems to think its jetting and timing?? what your thoughts..
 
timing would be the next easiest thing to fix. pull the right side palstic cover off and look behind the flywheel. tell us if theres an adjustable timing plate on there. if there is, you will be able to see the adjustment parks at about the 2 o'clock position in reference to your flywheel. no gasket needed.
 
alright, so just pulling your plug and looking at it tells you nothing.
your actually going to need to do the test.
get your blaster out somewhere, hold it full throttle, then flip the killswitch and after that pull in the clutch, now you will be able to see what your plug is actually telling you. do not start it obviously, or kick it over or anything, as soon as it dies, push it back, and check the plug.
this is what you want to look for.
