Got a set of JIS and tried tightening then loosening. Sprayed with penetrating oil. No go.
Another thought do I need to take the cam cover off? Not for the screw but to get the drive aligned

Has anyone tried removing the drive in the head to replace the seals? The cross head screw on mine doesn’t want to budge

Gus. Yes item 21
Dave thanks

I’ve never had one fitted on my bike. I assume from the part I have it is secured behind the brake splitter on the lower yolk

I worked in the seal industry in the dim and distant. Valve stem seals are controlled leakage devices they need to let some oil through to keep working

Not sure I see how this works. If a seal is worn what does do? Increase viscosity? Fill the gap?(risk of clogging the oil galleries). Make the seal swell? (Then it will do this to all the seals)

Will you guys stop putting Tridents on the site for sale my resistance is failing!
Lovely bike good luck with the sale

Ignore my comment. Had a quick dig around in the garage caps are The same.

Just as info. I have a head with 8 separated bearing caps. Assume that’s a earlier 900

Bill,
whilst I could afford it the following divorce would wipe me out. I have too many toys already I am told I'll do the raffle for the unregistered T160 from Museum instead. Good luck with the sale.

Nice trumpet
Was my other want it bike.

Will join you for the ride out. Zed still has no clothes:( so I’ll be on the CBR 400rr

I hope to come along as it’s very local to me. Not sure I’ll have my paint set back and fitted.

Thanks. Think I like that better than the long ones

I’m going to go back to the big stud indcator lights. Not sure if to go with the std long stems or fit short ones. Anyone have pics of short stem install
