shee4202 Posted March 10, 2004 Report Share Posted March 10, 2004 I want to port my cylinders but am low on cash. Has anybody tried to do it themselfs with race logic templates? If so how did they come out? Is it worth it or just spend the extra cash to have them pro done. Quote Link to comment Share on other sites More sharing options...
Big Blue Posted March 10, 2004 Report Share Posted March 10, 2004 IMO let a professional do it you will probably get better results. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted March 11, 2004 Report Share Posted March 11, 2004 Porting is an art. Don't get me wrong, you may gain some power from using templates... but probably not as much as your gonna want. I bet if I gave 5 builders exact specs, they'd all come out different. The angles inside the transers, the different shapes each builder uses inside each port... it's an art.

Ultimateduner Posted March 11, 2004 Report Share Posted March 11, 2004 Cylinders are an important part of the banshee. I wouldn't mess around with them if i were you. let an expert do it. Quote Link to comment Share on other sites More sharing options...
Hiram Posted March 11, 2004 Report Share Posted March 11, 2004 Im a do it your self guy, and love to buy tools so I spent about $450 in special tools(foredom flex tool with different hand pieces, burs and sanding drums, ect..) and the race logic templates and did my own. It came out great and really rips, It runs so good that I just started doing a freind's that said compared to two other local builder/porters bikes he got to test drive he loved mines way more with the wide power gain this type of porting gave my quad. I say if your a do it yourself guy with good hand skills go for it, if you don't trust yourself then ask around and like they said don't let price be the deciding factor and make sure it's someone that can work on the transfer port windows as this is where most of the power is gained.

dirtbike killer Posted March 11, 2004 Report Share Posted March 11, 2004 I did the race logic also, and my shee is a hell of a lot faster. I'm going to dyno it this week. I beat a shee that did 58 on the dyno sunday, so I guessing I'm in the 60 plus hp range. The kit is easy to do, you just have to take your time.

banshee tuner Posted March 11, 2004 Report Share Posted March 11, 2004 You can't go wrong with the race logic. I have seen shops use them and just freehand the transfers and customers were very satisfied. But yes a pro will get you more power if you have the cash. It's your decision depending on how much money you have to spend. Quote Link to comment Share on other sites More sharing options...
shee4202 Posted March 11, 2004 Author Report Share Posted March 11, 2004 what do you mean when you say a shop can get you more power? Quote Link to comment Share on other sites More sharing options...
350duner Posted March 11, 2004 Report Share Posted March 11, 2004 Good porting guys know what works and what doesn't. They can build the engine to suit your taste. A template is going to be a compromise for all-around power (don't get me wrong, I'm sure it's much better than stock). If you want to learn the theory behind porting you should start with the book "Two Stroke Performance Tuning" by A. Graham Bell. The book just plain rocks. It teaches you everything from what do do with all your ports to building pipes to suit your motor to carbs, ignition and gearing. Most of it is geared toward GP type bikes, but they talk a lot about the RZ350 (yay) so it's real similar, and the theory still works for ATV's. Keep in mind if you want a good set of engine porting tools you'll probably end up spending as much as you would for a shop to do it. But if you want to learn how and do multiple engines it's worth it. Quote Link to comment Share on other sites More sharing options...
banshee tuner Posted March 11, 2004 Report Share Posted March 11, 2004 Exactly what 350 duner said the templates will be a tremendous gain over stock but is equal to about a stage 2 port. An engine builder can take more material out and get more power. If you take more out without knowing what to do your engine will not run right. To sum it all up the templates are $89 plus how much you spend on grinding and sanding tools and is well worth the amount of money for the power gains, but an engine builder can get you more for around $450 so you make the call. How much power can you afford? Quote Link to comment Share on other sites More sharing options...
MotulMonsta Posted March 11, 2004 Report Share Posted March 11, 2004 I say do it yourself. If you are willing to accept the risk..Have at it. That's how you learn. Pro engine builders wern't born, they were made. Trial and error practice and patience. One day they will die and who's going to replace them?

jstocker Posted March 12, 2004 Report Share Posted March 12, 2004 Hey does anybody have pics of the race logic porting after they were finished. I am in the midle of working on the race logic cylinder porting. Just wondering how they look. It is a very interesting progect. Thanks Quote Link to comment Share on other sites More sharing options...
ferociousllama Posted October 20, 2006 Report Share Posted October 20, 2006 Does anyone have any templates that they are done with? if so can you send them to me? or can you just make a xerox copy of them? I just can't pay $89 for a template. I have the tools to do the job but I can't justify spending that much money on a simple template.

djackbanshee Posted October 20, 2006 Report Share Posted October 20, 2006 (edited) this is what do it yourself porting looks like a real mess http://www.bansheehq.com/forums/uploads/po...-1161147458.jpg Edited October 20, 2006 by djackbanshee Quote Link to comment Share on other sites More sharing options...
kubiac3 Posted October 20, 2006 Report Share Posted October 20, 2006 You could polish your intakes yourself. I did it on mine and noticed a good amount of gain, nothing that port work can do but it was pretty damn good for a do it yourself project. it was easy too. Sand paper is all you need Quote Link to comment Share on other sites More sharing options...
