    A123 motorcycle battery

    Hi Everyone! I'm building a custom streetbike,supercharged SV1000, and am fitting a liFePo4 battery due to space restrictions. This is well and good being a fairly straight forward process, but getting a definitive answer on whether or not I need to run a battery BMS (battery maintenance...

    Perimeter front brakes

    Triple Z, Yes indeed few and far between here also.I started the ball rolling in meeting up with various engineers and the like to get ideas on the exact materials to use etc.One particular guy is building a street registered replica of an '83 CB1100 race bike using 954 running...

    Perimeter front brakes

    Triple z, It certainly isn't modern faddery that interests me,just beneficial technology.Sometimes one gets mistaken for the other.As you may well know in 2000 KTM introduced wave brake rotors on their enduro and mx bikes for scraping and slinging off mud.Not heaps of call for this on a...

    Multiple Valve Application, Honda

    Hi Mr Hotfoot, Yes a tricky question indeed.A guy I work with was telling me yesterday that he's running a Datsun 180b piston in his IT490 dirt bike minus the oil rings!So it's all possible.No doubt there will be valves of the exact size you need somewhere in the automative archives,it'll...

    Perimeter front brakes

    Hello out there, I have a question about the unsprung weight advantages versus the higher gyroscopic forces generated from a wheel with a rim fitted disc brake.Among some low speed rarely ridden custom Harleys,Buell is the only manufacturer embracing the perimeter braking concept.It's seen...

    under engine motorcycle exhaust

    Hello to the experts, I have a question regarding the feasability of running an under engine exhaust system exiting in front of the rear wheel for a GSXR 1000 project.The machine will have a trellis frame,swingarm,linkageless shock and no fairing.Would there be any adverse effect on running...
