    Got the subframes done tonight ( except for the lower mounts ).They came off ok,I just hope they go back on easy,I tried to make sure that I tack welded everything on the bike well.Now I will do all the final welds and grinding and make them look good,paint them and back on before the weekend.I'm hoping that the rig will be ridable by Sunday night !!..This is the RIGHT side..

    I got the subframe done today( welded,sanded,and painted),Mounted it on the bike,tightend all the bolts down.Here is where I ran into my first real problem of this whole build.IF I push REALLY hard ( back against a wall and feet on the subframe)I can get the subframe to move side to side about 1/8-1/4 of a inch,in the front.I know that doesn't sound like much BUT the sidecar will put alot more stress than that ( I THINK ??) and I don't want any flex if I can help it.So tomorrow morning I will go back out and sit next to the bike until I find another mounting point for the bottom of the subframe.:cry

    Yeah.... unfortunately, if you can push it around that much by hand, I believe it will be moving all over the place on the road...

    I have had setups on my Airheads that I swore were rock solid when I "tested" them in the garage that I could see moving when cornering. And those had a full double-craddle perimeter frame that a subframe was attached to.

    That sucks in a bad way... :cry

    Any pictures for us armchair engineers? :lol3
    This is what I am in the process of doing to mine to stiffen the connnection at the footpeg mounts. (clamps the brackets to the frame)
    The rod goes from one side of the bike to the other with just enough room. Hope this helps though yours has a different engine.
    Mind you I am a bit frustrated by being away from home for a month now apart from a few days with at least a week to go before I finnish the current project. ( its cool though with helicopters and a mountain involved)
    Look forward to your solution.

    Well my subframe mounts to the frame below the tank ( between the GIVI crash bar mounts) and to the foot pegs.I DIDN'T go to the centerstand,I wanted to keep it for tire maint.I have a crossbar connecting the front BUT it's just bolted.I was thinkig about welding the cross bar ( if I have to remove the subframe I would just cut it ).I might have to go to the centerstand mounts!!,but that is far back from where the movement is.I wish I had that extra motormount like the 650 has !!!.:huhI'm heading out to the shed here soon....

    IT'S ALIVE !!!!!!!.I got it all hooked together today.I still need to pull it apart and do all the gussets and final welds and paint.I ended up gusseting the crossbar and it's better,but I'm gonna go ahead and use the centerstand mounts for support.

    Thanks for all the support & help guys your ideas are saving my A%$.So I went out to the shed tonight after work and did some messin around and found out something that could put a halt to forward progress.I can't get the sidecar suspension to move !!.It's rated at 250lb,BUT I weigh 285lb and the frame weighs about 100lb and when I stand on it ,it only moves about 1/2 inch ( the back of my bike almost bottoms out !!).My wife only weighs about 150lb so it could be a BUMPY ride for her.I'm going to contact the builder and see if there is anyway he sent me a higher rated one ( I hope he didn't cause it's welded on REALLY well ).OR maybe he has a way to soften it up??..On a positive note,as I was jumping up and down on it I watched the subframe and I COULD NOT see any flex!!,I know that road stresses are higher but I was happy that it stayed put.Also while I was just sitting there thinking about what to do with the suspension I went ahead and mounted my steering dampner.I don't know if I will really need one BUT it will be easier to remove it later than add it on,also it only cost $12.00 with shipping from ebay !!
