I've got two of Dave's seals in place, one on the Commando the other on the 650ss, which requires the Dommie version.
They are simple to install , inexpensive and they work.
Tough to see how that could be improved upon. Show polish on this particular part is not a plus.
comment re bobs mention of Walridge. About 15 years ago I had a somewhat similar experience with them. I was told not to call as I was taking up too much valuable time, but feel free to email questions. This was from Mike.
Also, the lady order taker in those days could get very snarky.
For example, you ask about a part and she spends 30 seconds finding the part and pricing in the system. You decide not to add it to your $400 order as the part is $220 and you thought it might be quite a bit less. She would make it very clear that you are a cheap SOB and have just wasted her time.
Thankfully, that lady has retired/moved on and a very cheerful , helpful lady is now taking phone orders.
With Mike, I will admit it was off-putting to be told to stop phoning with questions about details on the bike parts used in the resto the 650ss. Just after purchasing the 650ss, I called there twice as they had supplied almost all of the parts used in the resto of the bike, which was done by the previous owner, the Ontario Vintage MC club.
I got over it and the email works fine. I think they have changed things over the years and seem to be very interested in keeping customers happy now.
Back then I also got some snark from another well known lady.
Norton parts dealer/order taker, so maybe it was me?
Coincidentally , that was over Dynodave clutch pushrod seals. They didn't sell them and I thought they should.
Anyway, I haven't had a problem with any of the parts dealers for years now.
Online ordering is a blessing!
