Everyone... thanks so much for all the comments and help.
Beach Guy: Awesome.. thanks for looking that place up for us. I took the wheel off this morning and gave it a tapping about to get it as good as I could, but it is still not great. If your amigo can roll it out, then perfect. Will look into getting over to Managua Monday morning.. we are currently in Leon so a bus shouldnt be a problem. Thanks also for the shock offers... think I have sourced a pair though. Thanks all the same.
Garry: Hi, All part of the adventure indeed.. my new catchphrase has become "Tranquillo" !
Will post some pictures of the rim as it is now following my beating session.. also will post some pictures of the shocks.
I also posted this on the airheads forum... to keep things simple will now post updates only through that thread:
Once again everyone.. thank you
