flattrakker Posted October 30, 2007 Author Report Share Posted October 30, 2007 Im speechless! whats so bad.. not like im doing a drag port with 800 grit. Quote Link to comment Share on other sites More sharing options...
sheerider1026 Posted October 30, 2007 Report Share Posted October 30, 2007 if you are just going to massage the casting flaws out i would use a dremel with a smooth stone or sanding wheel. i was thinking of doing this myself.. would it hurt to open up and smooth the transfers and intakes myself?? not going to change the port timing or anything just open up what is already there?? any suggestion?

flattrakker Posted October 30, 2007 Author Report Share Posted October 30, 2007 this is what i was planning on doing and another forum on here a guy said he did it with paper and it really helped/worked and looked good. snopczynski freaks out!

I'm not going to tell you you can't do it, i'm just going to say you can screw up VERY EASILY by just using a dremel. One little mistake, frick a fly lands on your hand and you flinch big enough, you will screw your cylinders. Unless you have a stand to set the dremel on that keeps it steady, and you can move it around within the cylinder while still on the contraption holding the dremel....I would not recommend cleaning up your cylinders if you have never done anything like this before. this is what i was planning on doing and another forum on here a guy said he did it with paper and it really helped/worked and looked good. snopczynski freaks out! The only spots I can really see sandpaper actually taking material away would be to smooth out the transfers, smooth out hte exhaust, and smooth out the walls/burrs on the intake ports themselves, not the entire intake. If you are going ahead with it, I can't see too much of a performance gain with just sand paper..unless you spend hours and hours and hours using all different types of grits so you can take a good amount of material away and then working your way up to a smoother sand paper. But these are just my opinions, if you go ahead with it, just take your time and make sure you have a good eye so you can match what you have done to each cylinder.

sheerider1026 Posted October 31, 2007 Report Share Posted October 31, 2007 i was thinking of using a very fine stone to smooth out (and make a little bigger) the ports (transfers, exhaust, intake.. nothing heavy as far as changing the shape of the transfers or the intake side.. not going to get into the sleeve where port timings can be altered.. just tryo to get things a little bigger and smoother.. what u think.. can it hurt?? think it will add more power basically everywhere?? just going to trails ride it.

sheerider1026 Posted October 31, 2007 Report Share Posted October 31, 2007 also wanted to add that if u have anewer dremel tool or are going to get one.. get the one that has the rpm adjustment.. turn that thing on a lower speed and take your time.

2strokespirit Posted October 31, 2007 Report Share Posted October 31, 2007 Porting is not every backyard mechanics job, but I have to say, I have my own shop in SA and around here theres not a lot of people that can do a good job so I have done some RGV250s and CRs with really good results, I have messed up some cylinders and done ### jobs as well, but my suggestion is, get a old pair of cylinders and try it on them, If this is something you want to do, you will have to start somewhere. I am still teaching myself and working threw books like A GRAHAM Bell's 2 stroke performance tunning and so on. But this is a trick thing especially when you get into port timings and transfer angles, but I love it and gonne push on in my shop till I get good results. One day all the good builders will not be there anymore, so there have to be new ones to take their places and in my opinion its only experience and 2 stroke technical info that will get you in the forefront of things oh yeah dont forget the $$$ Quote Link to comment Share on other sites More sharing options...

Bansh-eman Posted October 31, 2007 Report Share Posted October 31, 2007 tracker it sounds like you might be in a little over your head. you should sit down and do a little research before trying to go at it with paper.. you will find out VERY quickly this isnt to correct way to go about it. doing it your self is awsome, as long as you have the knowledge, the know how and the tools and time to sit and learn, and be prepaired to ruin many cylinders so perfect the art of porting. Becsue its just that. an art. its not just something you get out paper and smooth away the casting flaws... unless you plan on making changes to the port timings and port angles, your probly not going to ee any differance. how ever on a side note, remember that on the intake track you dont want it to be smooth. you want it scuffed up... this helps atomize the fuel Quote Link to comment Share on other sites More sharing options...

And sorry if I came across as an ass earlier, I just wanted to state that you shouldn't use a dremel if this is your first time porting cylinders, or even if you haven't used a dremel much for anything before. I did a clean up port on my cylinders, and no I didn't have any extras laying around. If I screwed up, well I would of had to find some stockers somewhere that fit my bore, or go get them bored out, which would be even more time and money. However, my cylinders turned out good. I noticed a decent amount of performance once in mid-high rpm and they pull harder and longer than what the stock port did. I did not use a dremel or sand paper...I used an assortment of hand files. Now some people may think that is wrong, but it worked for me, and I can control files a lot better than a dremel. The first clean up I did, I just opened the intakes some and opened the exhaust a tiny bit(hardly anything really)....put it all back together, ran it and decided I will do some more port work the next day. So the next day I took it all apart and opened the intakes more, made them flow better, smoothed out the transfers and opened them a tiny bit to help them flow more, and i increases the size of the exhaust port as well a little bit more to allow this added mixtures to escape faster and more efficiently. I do not have any pictures of my current porting set up, however these were taken when i did my first clean up port...Maybe these will help with your decision and thoughts on what you could use to clean them up: Stock: Cleaned Up: After those pics is when I took more material way in the intakes, transfers and exhaust ports...but I do not have any pics Edited October 31, 2007 by Dinner Quote Link to comment Share on other sites More sharing options...
sheerider1026 Posted October 31, 2007 Report Share Posted October 31, 2007 so after you took more away what hwere the results?? did u gain more power basically everywhere?? still the same power characteristics just more of it? Quote Link to comment Share on other sites More sharing options...
