    Guys i don't concern about ARAI i don't think for them ! I need V twin firing under my seat. and i m in free India to do that.
    we need to creat blue prients, the good news is that we got the CAD designer, now the step will be basic measuring and creation machanical blue prients.
    I can't belive this, we are doing this guyes. just search now if u have the measurements of old engine ??? thanx all.
    May I know how you are measuring the engine outer profile?..Do you have that instrument facility?...
    Its not about just vrooming the engine, sharp cuts, top speeds...A true biker should understand his machine

      I dont think you have to homologate self made bikes in India or anywhere else,
      as for the engine and Chassis I don't think that the chassis of Bullet will be able to take the load of the engine and the stress of riding,
      You can contact on guy who made a chopper out of Maruti 800 engine and another guy who is making a Bike in Bangalore I think,you'll get him on Tbhp.

      Moreover you wont be able to source most of the parts that you would require,Mostly importing these parts will be a expensive affair..

      But still
      Best of Luck.
      Speak Less,Speak Wise!

      Sarcasm is my automatic response to stupidity.

          i just wonder why every one concerns about the ARAI ? i do respect the government rules and regulations. but that come when the bike comes on the public road !!!

          guys ! guys ! guys !!!

          lets design, build then we will put the product at ARAI ? we can't blame ARAI about not getting our bike homologed cause we have not put the bike at their desk ? we don't have the blue too, ok.
          so far i came to know that ARAI is just certification authority, ARAI follow the rules given by "CMVR" most are clear and helping in nature. and we are following all the rules and regulation to build a bike. and why cant we produce the bike with Bharat stage III, well within emission norms and safety feature.
          thanx haxro to bring those things in my notice, because of u i read the CMVR act completely. for the next post i will right something about the emission norms, safety and CMVR.

            hey i got the basic desinger

            got a man how is ready to work with us. he is converting our idea of V twin in the basic 2 D cad modeling. i will soon put the basic here on line.

              great man.
              even i got a designer.
              my cousin, he works in honda and is an automobile engineer.
              he had learnt engine designing and stuff.
              he works in CAD and CATIA.
              and the best part is that he is willing to work.

              by the way, lets discuss ahead..

              as we'll have to get the crank done by forging.
              i suggest why don't we build the thing from aluminum??

              these forging people will first forge the aluminum and then will do machine work on it to make it perfect and best.
              if it has any issues, we'll ask the guy to replace it with new one..

              also if we go for aluminum for crank, why don't we go for aluminum blocks too??

              what say?
              weight will be less.

              it won't cost too much..
              will do great job.

              if you can personally meet me and my engineer cousin next Sunday, it will be great.
              show us the design your designer makes, also we'll discuss bits and pieces here and there.

              and do 1 thing, send me CAD of OEM RE 350 engine if you have, i can make one here and you can make one there, we'll see what works better and looks better...
              Giving a lot to a fiero.

                NANO dont take this as criticism, But Aluminium has the shear properties of.. ,well lets just say, there are very few metals which are worse than Aluminium.

                You should be looking at Aluminium alloys if you seriously want to make a crank from a aluminium based component.

                I cant do much explanation at this moment, am sleepy.
                But check this out Crankshaft Design, Materials, Loads and Manufacturing, by EPI Inc.

                It will give you the idea about the requirements to actually make the crankshaft, A lot of forces need to be calculated in order to determine the the dimensions/material used for the machine element.
                Crushing forces acting on Crank bearing,
                Shear forces acting in the crank pins,
                Torsional forces acting on the journals,
                These are just a few that you need to know.

                hope that this site helps, i haven't gone through it completely.
                For now gn people and Happy Independence, in case i don't see you all tomorrow.(20 mins to midnight)

                    any one who have any component of RE engine plz measure it and photo it and pest it here. we need that for cad designe. ppl from all the India who are working on this project need it. plz do it. thanx

                      hey guys i found this. Enfield Bullet 350/500 Spares & Repairs, Delhi, India - Bullet Spares - Crank Case
                      take a look and u will get idea wat u all have to designe. though it is not measured, still help a lot for the basic designe. this is for those who is really want to contribute.
                      thanx.

                          guys i got the news from south, a guy is there how had S&S v twin engine, he is working on project to make it revers engineer and then to reporoduce it. i m trying get some basics and designe but refuse to do that. i offfer him to meet him may be he will call me. if this could work out and if he give us the engine for some time to get measure and revers it our time and money will save. and soon we can ride it. well i study the homologe process and it is not to tough for the bike. just keep the emission norms low and that is set, well we can have safety at high. it will take 8 months to get on road once we put the engine on the ARAI desk. guys pray for me that i can get this man to give us engine.


                          but plz post the parts of RE and to make the designe. thanx...

                            guys take a look at this and tell me if u can get the idea for the designe space, next time i will get the measured by some scale ok. but hope this will help all those desingers for initial concept. plz reply me wat u want more. thanx..

                              I will post some images of the Alias software.This will give you an idea how the 3d softwares work.But if you are referring to the actual milling data, you will need to export these surfaces to Catia software.

                              There are three types of softwares for designing.
                              1:Approximating softwares:3d s max, Maya,etc. They use polygons for just creating a similar looking object. No technical accuracy. Used in entertainment industry.

                              2:Surface modelers: Alias,Icemsurf,Rhino,etc.-They create surface to class A industry standards. These are used in industries requiring seamless surfaces. For cars and other automotive industries.

                              3:Volumetric softwares: Catia,ProE,etc:-These softwares can actually measure volumes of the 3d surfaces. They can also provide data for C&C machines.

                              I know how to use Alias software. Check out the images how it is done.

                                get this, though its not scaled but still can give internal idea.
