Shifter conversion back to right side.

I have a '98 Bullet 500/4 speed gearbox with the monkey motion crossover linkage that puts the shifter on the left. Is it still possible to find the parts necessary to convert it back to a right side shifter?

The conversation back is done with all factory parts, everything should be available. What might be a problem are the instructions on how to put it all together, I'll do some digging.

The Snidal manual has a good description of the basic right foot shift installation for the 4-speed box. However, it lacks the information on adding spacers(washers) to bell crank shaft to get the correct lash for the bell crank. Another source of infomation for the 4-speed box is the Hitchock's tech board. http://www.hitchcocksmotorcycles.com/technical-notes. In the technical notes, click on "Gearbox and Clutch", then look at "Albion Gearbox Rebuild Parts 3,4,5".

The parts you will need are 1)Bell crank, 2)New inner cover, 3)Bell crack bush,4)Inner shifter lever,5)Right foot shift lever,6)Gaskets, inner cover, kickstart shaft gaskets, 7)Sealed Main shaft bearing (optional, '98 was unsealed),8)New rear brake lever (left foot, I seem to remember a new brake shaft bushing was also needed for this lever). On my kit, the opening for the kick start shaft in the new outer cover needed some additional machining as it was too tight for the kick shaft.

HooHoobolin has a video of his installation at : https://www.bing.com/videos/search?q=ro ... &FORM=VIRE

That's it? I remember the kit having 30+ components.

Thanks for all the input. I've researched youtube and the usual internet sources for info. Found the video that was referenced. It's a job that's within my skill level, plus I have a lathe, mill, and welding equipment if (hopefully not) needed. I remember when the "kits"were available, but I don't see them around anymore. Even the usual sources in India don't "package" the parts any longer. I guess with the cast iron bullets being out of production around 10 years now, there no longer any demand.

Bob,

I can put a kit together for you. How soon do you need it, yesterday? ;)

Tim, thanks. I'm not in immediate need. This is a "from the ground up" project on a bike I've had for years and I'm considering my options. I'll keep your offer in mind and let you know if I decide to make the conversion. As an alternative to the right side conversion, Plan B would be to improve the stock left side linkage. I know bronze bushings have been used to replace the stock plastic bushings, but I wonder if the linkage could be converted to rods with precision Heim rod ends?

It has been a lot of years since I read this, but I am sure Mr. Blasco covers everything you need to know about the linkage in this Article.

Thanks, Tim. I had run across that page but hadn't read it in detail until now. Trying to improve the linkage sure does appear to be a case of rapidly diminishing returns.

I've discovered that a friend has gearbox parts from 50's-60's twins and he's offered them to me. Does anyone here know if the gearbox end covers and shifter parts will interchange with the Indian built Bullet 500?
