little john tranny ever wonder whats in one
im sure everyone has seen the ads in the old biker mags for a little john 5 speed tranny but have you ever seen the inside of one well heres your chance
the case was made about a half and inch longer than a harley case and the countershaft and case bushings were removed and replaced with the plugs shown below
the mainshaft was made longer to accomidate the extra gear the first second cluster was shortend about a half inch and the main drive gear now has two gears on it instead of one
the top looks just like a rachet top but is slightly longer and has a square shape on kicker end the shift drum is made out of solid steel they also machined an extra groove in it for a third shifter fork also the two shifter gears are cut on slight angle looks like its to make up for machining errors
the shifter fork finger portion looks like its from a turtle top the forks them selves have been narrowed so they wont hit other gears
the counter shaft cluster doesnt have a removable shaft one end is a hole bearings go in and the plug slides into it the other end is supported by a plug bearings go in and the cluster slides in both plugs go into the case and supporting the cluster

cleaning out my computer again
cleaning out a few prism /tank bike pics that got on the net figured i would postem before their gone
i dont know who built the red honda but its real nice
done at last
well i can finally say i am finished with the mold
yesterday i added on the little square that will make a notch in the housing for the liscence plate lens i screwed it on and the cut it to a 2 degree taper to match mold top half i also removed an inch off the bottom to get ride of some weight
the orginal housing fits the mold so well that the tapers lock to the piont i have to pry it off
after seeing how hard it is to get the orginal housing off the mold cory and i added the aluminum plate with ejector pins on the four corners of the housing so i wont have to pry the housings off i will be able to hit the corner of the mold with a rubber mallet and the ejector pins should just push the housing up enought to take it off by hand
hopefully in a day or 2 i will get to try casting a housings
