My first try at P&P

[ruthless_one3k]

this is an extra jug I have(200cc .080 over) and I thought I would try my hand at porting and polishing. what do ya think? I guess the real question is will it run when i put it on the bike? only one way to find out for sureI:I

hope it works!!

doesnt appear you did anything real harmful ,although it doesnt look as though yo udid anything to make anymore power either

i could be wrong, but i was under the impression that part of porting was to increase the size of the ports.. the polish was to reduce turbulance..

I made the intake ports a little bigger on the jug and cut the piston to match I also took a little off the skirt and matched the piston up a little better but I didnt want to take to much off the skirt of the piston as it was getting close to the intake port. I then polished the exhaust and made it a little wider. I dont think it will make a big difference but im just gonna do a little at a time and see what happens. When its time to do A P&P on my 240 i'll be call'n up Flotek they look a little more high tech than my dremel tool:-D

going wider on the width of the exhaust will genraly increase torque but it must be relative ot the chordial width of the bore or youll lose needed ring support and see prermature wear ,thsi is why bad porting can be unrelaible and overheat ,on a yfs the stock intake already outflows the transfers and exhaust so in itself that really wont aid power much maybe a little quicker response .also there is no benefit to polishing any ports or intake,good flow characteristics and proper duarations shape and area is where the power will be found on about any 2 stroke

Yeah, thats why when I get ready to do my 240 kit im call'n you. you know way more than I do about P&P. I watched the video on your site and that blaster looks sweet cant wait to see what a 240 will do with a proper port job mine looks like they just pressed the sleeve in and thats it. they didnt even bother to match it up with the jug.

yeah they can be pretty rough in stock form thats for sure ,but we can fix you up to make some real performance for its size B-)
