hi everyone, i Just got my tandem running. put the engine in because of the hills in Durban where i stay. it makes a HUGE difference! i have the 66cc kit and i use a big 48 tooth sprocket in the back since i'm not going for top end speed, and more for pure torque. i have also built a girder front end for the bike, it is heavy but it looks cool! will put up pics of the completed thing once i've taken some. here are some of the pics that i have: i had to cut the frame to make the motor fit, and i got a much longer chain than the one supplied in the kit: here is apic of the fork mocked up on the bike, since this pic was taken i have made a spring mechanism for it and it works great! it also solved some handeling issues i had with the origional fork: i have had the whole family on this bike and i works really well! that is myself, mywife and my little 2 year old daughter on the back in a baby seat. she is a little nervous of the noise but gets better everytime! i'm hoping to build my own expansion chamber to get some more go out of this motor. i do not have the $$ to buy one so making is really my only option here. hoping someone that has had success with making them is willing to share some dimentions... you can see the progress on the tandem here: www.triplepowertandem.blogspot.com cheers!
