Those pics of DaveM's bottom chassis cracks may,may not be JUST due to the sled conversion,but certainly would have accelarated it so.
I say this because one of my STOCK Odys had same fatigue crack where the bottom cross member is welded to the LHS bot roll cage.
I only found it because I had to get the motor (( Internal Combustion Engine ? )) ((Internal Combustion Engine?)) out for rebuilding.
Then a couple of other members also said they had same crack!
I urge all you Ody owners to check your cracks.

We have been very busy at work, landing several new major projects. This is great for everyone's bottom line, however, not so much for getting my Ody done. I did set some time aside today and managed to get the Engine on the Farr conversion mount, and remove the frame section that interferes with the recoil starter. I used cardboard to lay out the pattern for the section to be rebuilt, but found out I didn't have any plate to make the parts. I'll order that up and get it welded up later this week. Feels good to be making progress.

what the velocity stacks for?

Velocity stacks are for 2009-current Gen II Yamaha Vmax. Gets rid of air box, and have individual filters on top.

If you have a part you would like made up, send me a sample of what you need so I can have all of the critical dimensions, and some ideas of what you need, and I will look into getting them done. My machine shop is amazing, can do just about anything.

Yesterday, I began looking into having transmission output shaft adapters made that eliminate the stock Odyssey drive axle, replacing with a stub that a CV would mount to. I know it has been discussed nearly to death around here, but I have access to some great resources that can make it happen if we can nail down what needs to take place. So, any ideas on what CVs, hubs, and any other items to do a conversion, and I will get going on it. I am looking at doing this because I am worried about breaking an axle now with the 583 going in.

Yes, we can do the CAD work. If you have a stock manifold and Mikuni boot that I could use for all the measurements, we could draw that up pretty quick. I do not have an Engine or any of the associated hardware to do the modeling with. Other than having a manifold that fits the Engine and the intake boot, from what I read in the other threads, it needs to be angled properly for clearance. I am happy to try this, but would have to send one out for trial fitting. Let's make it happen.
