Take a look at the 1st picture. The lenth of the splines on the "drive end" of the driveshaft are shorter than even the shortened end of the u-joint end of the driveshaft. Every failed driveshaft I have seen has fail at that point and I wonder if it isn't a designed weak point. If it fails at this point, you can disengage that spinning driveshaft via the clutch, if it fails at the u-joint end, it is going to continue spinning until you bring the bike to a stop. Probabaly bovine scatology, but there must be a reason the splines are made that way.

Great write up BTW.

OregonLAN,
Thank you so much for this very informative post.
I'll have my modified parts from Aric next week and will have this printed out and close at hand when I do my upgrade.
Thanks again!

I followed the directions of this post

Thanks to all who researched this mod and to this post, I have a better functioning C50. Three and a half hours (1 hour to stab the u-joint) of following the directions (except 1/2 inch diameter bolt holes was still a little small) and I was cruising down the highway learning the best way to use my new drive train.

I read all I could find on the dj drive for months before tackling the project and with a couple of friends and VR's brains, the job wasn't that bad.

Special thanks to those I PM'd and gave needed info.

Great write up and pics OregonLAN

I have two questions:

Why do you think you will get a higher top speed?

Why do you think the spacer needs to be hardened steel?

1. Well, I think you can achieve higher top speeds given ideal conditions. However, it takes a really really long straight/flat stretch of land. The fastest Iíve had mine up to is 93MPH (or 98 on the speedometer). I was unable to achieve these speeds before the drive; YMMV.

2. The original spacer is hardened steel. I would assume thereís a reason for it being hardened otherwise Suzuki would have used cheap gray iron. Where I work, we use hardened steel for items that are prone to wear...

My C50 runs 95 mph top speed on a long flat stretch. I can accelerate to 90 mph with quick acceleration. From 90 to 95 is slow.

I like the quick pick up. I out ran a Kawasaki 1500 nomad at the race track. When we reach a speed around 60 0r 70 mph, I really pulled away like he was sitting still.

The C50 it a 805. It was made to wind up fast and tight. Engineers would have given the C50 a different ratio if anything else worked beter.

My C50 runs best at 70 mph. It's very smooth and the stock drive ratio gives me great acceleration at high speeds. Just ask the red mustang which tried to run me at 70 mph on I 40 at Hickory NC. Left it behind.
