Hi guys...new member here
I've spent quite a bit of time on the XS650 board and now I'm taking on a 1978 XS1100 standard
Above is a picture of the patient preped for surgery
I've read the second gear post adnoseum and also what I could about the Bob Jones modification. Here is the Jones link:
http://www.merriamcycle.com/high-performance.html
And here is the paragraph referenced:
"The transmission has the second gear modification with the spacer relocated on the other side of the fifth wheel gear. On a 1978 Standard the fifth wheel is in two pieces unlike later models giving better lubrication, however the replacement gears made later will interchange in this bike. Moving the spacer in question to allow full meshing of 2nd gear requires a bevel on the spacer with a hand grinder as the tran’s shaft on this model has a taper where the fifth wheel gear is riding instead of a square shoulder as the later ones do. If the spacer is moved with out making this taper to duplicate the gear that has it too. The fifth wheel will bind up on the shaft and could overheat the transmission resulting in a failure anyway, so if the modification is not made this way, the cure could be worse than the cause. "
I'm not sure about the description above, but it reads like the reference to 2nd gear and 5th gear are reversed. Isn't this refering to the gears on the counter shaft? Mine doesn't have a bevel on the shaft where 2nd and 5th gears ride.
Looking at the gears out of the engine, it seems like this might work if the spacer between the circle clip and the 2nd gear were moved to the other side of the 2nd gear, that would space the 2nd gear closer to the 5th gear and allow the 5th gear dogs to engage further into the 2nd gear slots.
This pictures shows what I think is the spacer Bob wrote about, but in the OEM position.
This picture shows where I think Bob is recommending, but the sholders are square, so I don't know what has to be ground for the beveled shaft
Does anybody know about the Bob Jones method? I don't mind doing the beveled dog modification, but the Jones method sounds like it would be quicker.
Also, I've been trying to contact Merriam Cycle about some of his parts, but can't get a response. I ran across a post on this site that he passed on. Does anyone know how he is and if the shop is in operation?
Any help is appreciated
