new owner...need help

[geemann]

... I feel I have traveled back to 1991...

i was not aware that the NH came with a flux-capacitor!?!  that could be what is causing the mysterious thump.   try jiggling the flux capacitor.

glad to hear you got so much work done!  i hope we get a full ride report after you get the new chain on!

cheers,

You will....and as an added bonus.......PICS!   

Now if I can figure how to get the 1.21 gigawatts of power........and weld a long pole with a hook.....

WOOOHOO!!!!!!!!!   


THUMP THUMP THUMP.....is GONE GONE GONE!  Not sure which it was but frankly just happy its gone, and the new shocks are a WONDER to ride on. 
Next issue front fork seals replacement.  Thats gonna be next weekends project.  I am just thrilled the thump is gone and the ride is MUCH improved all ready.

Just a few more "tweaks" and it will be ready for "prime time".   

And as promised "G" here are some pics.

cheers,

I am putting my money on the chain/sprocket area, you would not BELIEVE the amount of S&^% in the housing behind the sprocket cover. My "theory" is the chain had a tight or bad spot in it that would not "bend" around the sprocket and would bang on the engine case or cover.

  I would tend to agree.  I had a similar mysterious thumping when a mechanic maladusted the chain tensioners after installing a tire.  I rode it for about 1200 miles before the thumping started and I realized what the mechanic had done.   Even after properly adjusting and lubing the chain, the thump continued and got worse ( I was on a 5K mile road trip at the time).  After limping it home, I couldn't see anything obviously wrong with the chain while turning it on the centerstand, but I figured that 1200 miles with a cockeyed alignment probably did something bad.  Sure enough, when I replaced the chain and sprockets, the mysterious thump went away.  On post mortem examination, the cockeyed chain had destroyed numerous O-ring seals.  While it wasn't readily apparent when inspecting on the centerstand, when I pulled the front sprocket cover off, I could see some binding in the chain as it tried to turn the tight bend around the front sprocket.

1 step forward and 2 back.
Started to tackle the front fork seal job today (got the chain issues sorted all is good with rear end now) and 2 of the front pinch bolts where striped seized tight.   So now I have some penetrating oil sitting on them........hopefully that will work if not the drill and easy out will be next. 

I guess its a good thing I wasn't in a Hurry to get this done.
