You are correct with the pinion angle. Maybe we need to get someone with the kit fitted to take of their front prop shaft and measure their pinion angle. And yeah using a new cross member will drop the front of the diff while the rear remains stationary(offset bushes in the rear might drop by 10mm). Maybe the solution would be to use the offset bushes on the rear cross member but not the front, but this reduces the amount the front diff is dropped. The logical answer is to fabricate two new cross members front and rear so that the diff is dropped evenly front to back by the same amount and hence keeps the same pinion angle. Could also use the offset bushes as well to get the maximum possible.
And that's about it for this topic ! Yeah spot on, that's why I thought I'd buy 2 second hand ones and have them on the table and work from that!
Apart from the bike she'b my only way to get around- unless I go all "transit India/Asia" and strap a ladder to the side of the bike..
What I was thinking -if I can't match the tube/pipe diameter for the rear cross member (one with the bushes) I can always plaz' the ones off the second hand cross member.. The front one is rather simple with it's "lay out" but once you start to look at the angles of t/case to f/diff that's the part that puts me on the back foot. Shite "I think I've just worked out the rear pinion angle issues!
Yeahhh Don't know about the drop bushes "personally I'd like all the mounting points to have as much rubber/urethane around them as possible" ,so if I can keep them original I would be much happier me thinks! But in saying that "If I couldn't do what I am hoping to do I would go with the bushes over "SLINKY'S Kit" any day!
Now that I have the new bump stops in I can finally measure how much room there is to drop it under droop- Going a 3'' lift you may have to take it down as low as leaving 5 to 8mm of the L/C/A to get a decent angle on the C/V.. But with the 2'' lift I have I may not have to get that close, so a diff drop of say 20mm might work...
I do know one thing- with the rear cross member I intend to give the sump a little more protection. I don't know if you have been under yours and looked forward to the sump but the rear cross member lifts up a exposes the corner of the sump. I am wondering if it is formed like that to disperse the torsion made from the diff?? Any thoughts ??? Compare the difference between the two mounting/fixing points of each rubber bush containment tube.
I know pictures pictures pictures- I wish I could do more than I do but once the hands are dirty and your in full swing it's hard to keep a photo journal of all the works.
I'll keep you'allllll posted.....
