Forget Bore, Port Job Instead, Head Mill????

what compression do you have freak? im thinking its around 10lbs per every 0.10 you shave? any truth in this?
 
keep in mind that just shaving the head won't give you max performance from your head. shaving it just brings the whole stock design down. you get some more compression, but it's still the same sh*tty squish angle. have the head redesigned to properly squish and you'll get max power.
i agree about kennedy_power, the guy knows more about 2strokes than anyone else i've ever heard of. shoot him a pm and search this forum for his posts. he's got pix up on his flickr w/ some shots of the stock head next to his head design.
also, his port and polish job is f*ckin perfect! make sure you're settled on your pipe before you p&p. the pipe plays a HUGE part in the powerband of a 2stroke engine. you want the p&p to match the pipe you're running.
videlicet, running a trail port w/ a top end favoring pipe is only gonna restrict your bike's potential. running a trail port w/ a pipe that has a strong bottom will maximize your peak power and give you the strongest band.

hence changing the squish band clearance, instead of just the shave is twice as much, but worth it
 
Get in touch with a builder.They will set you up right and let you know what you should and shouldn't do.
 
like i said before, pm kennedy_power. he changes squish band angle, size, and clearance and puts a radius in the combustion chamber. my compression is at 13:1 right now, runnin 93 octane.
 
idk flotek seems pretty awesome if you visit flotek preformance they vid of on of their blasters they ported on their site
 
Ok, so we can conclude that if i am runing 95 octane, i can safely mill my head 0.035" and that will kick serious ass, due to high compression?

(Its going to run with port job and Toomey B1 kit...)

Then thats the solution im going for ... The only demand i have is it is a bolt-on with no problems....no need to change ignition, timing or anything else!. .. just have the cylinder, head machined and mounted.. and ready to go! :)

well if you have the p/p have them redo the squish band, like he said kennedy redoes the whole head angle etc, along with the aggressive p/p he does, i have heard nothing bad about any of these guys so it is a hard choice to choose who to go with. but whoever you choose, you won't be dissapointed....but if you just want to shave the head, you can go for .035 with no problems
 
Thanks i really approciate the help, but i live in Denmark so its gonna be there the port job are gonna be done. Its a really pro cylinder shop that specialises in tuning hone bore etc. For cars , mc etc. But however i dont think they ever did a blaster so i hope its gonna be good
 
However i need to study this sqeeze band or what u call it, maybe i can give the shop some advice hehe

no trust me, kennedy knows everything there is to know on a 2 stroke, you won't be able to tell him anything, but like i said, send it to any of the 3 on here and you won't be dissapointed.
 
Today is the day!

I at work right now as we speak (good thing you always have a computer and blasterforum handy! :-) But when i am done here.. i am going to the storage facility where my Blaster currently are.. then im gonna take the head off and the cylinder.. (preparing for port polish and mill the head).

I have decided to go with the 0.035" like 2smoker.. and show the shop some pictures of redesign the head etc.. and hear them out of the plans they have for the cylinder... i think im gonna get thoose thing done here next week... need to get my paycheck first! :-D
