CB650 "Parts Bin Special"

I have to confess, I'm not an expert on the differences on the frames; I just read the log-book! I'll keep an eye out on any other 550's I see though.

.....took my Triumph 5TA for a succesful MOT last weekend so I'm re-energised for 2012......so now (almost) all bikes are MOT'd for the spring, but Parts Bin Special is choosing not to start and also leaking a lot of (nice, clean) oil from what appears to be the rocker cover / cylinder joint.

Two  possibilities:
- Not torqued down enough
- I missed out an O-ring during the rebuild

I'm hoping it's the first; don't mind if it's the second....anything else then who knows what it could be. Hope to get shed-time on Sunday to confirm.

Unbelieveably, the last post on this thread was March last year ...and very little progress made since then; motiviation was flagging as my forks/seals would absolutely not seal...fluid was literally gushing out and the thought of another strip and rebuild in the 'outdoor workshop' was too much (having been rained on during the previous 2x fork rebuild.

..... on the plus side I now have a new house with large garage and I can work inside and out of the elements!

 So, when last parked up Parts Bin Special needed the following for MOT:
- to put in working fork seals
- stop a leak from one of the carbs (probably a stuck float / overflow)
- be reasonably happy with the noisy exhaust
- I also noticed that I had an oil leak from one side of the cylinder so I may have missed an o-ring from an oil passageway during the rebuild.

Feeling remotivated I've now stripped one fork and rechecked all the dimensions of the seals and the stanchions; then checked my original order form Wemoto - correct seals had been supplied, so they mush be faulty. David Silver then supplied some pattern parts and these have gone in .... and the forks are sealed now. Result! I need now to complete the second side and reinstall works / wheel etc.

In the picture (if attaching works!) the working seals are in the packaging and have springs in - they've been pretty hard to insert into the forks. The third one is the leaky one and has no visible spring in it - just wondered if this is the reason why it doesn't work at all. Regardless, it was relatively easy to install so maybe jsut poor manufactuing tolearances.

No pics. You may want to try www.photobucket.com to upload your photos, from there you can share to any site.

Piccies from photbucket...
leaky seals - although this doesn't actually show how horrendous they were.....imagine that whole area swimming in fork fluid...


..and lovely new seals from David Silver. The un-packaged one is the old one and doesn't have a visibile spring in it...and it was nowhere near as hard to install as the DS ones.
