I dug up this thread from an in house-site search for rocker shaft shim info(can't remember what now,but close to Muskrats post-probably need another topic).
While I'm here though,will throw 2bobs worth+gst,vat,gdp,cpi.....! but first- Muskrat did you dig up the info for Olev where you got your fancy ally pushrods they sound good, one of my ex. ones has a bit of a chicane in it, and with the new springs figure may not take much to make it a hairpin! reckon I need newies
Burtons have ally ones not sure if 16gbp is for one or two, or four??
SRM have CrMo one 12~gbp looks like ea??
Now to push rod fitting- I am soon to do mine for the first time in a long time, have usually done it a combination of most methods mainly Beezalex......
with the aid of a hooked dental-type tool, it's a little fiddly but not THAT hard. Just rotate your rockers so that the sockets that engage on the pushrod tubes are down all the way, then drop the box on slowly. There should be enough friction on the studs that it will stay at whatever position you lower it to. Bring it down until the rockers start contacting the tubes and use the tool to guide the pushrod tubes into place. you should have at least a 1/4" gap to put the tool through and since the rocker arms won't be engaged you can do them one@ a time.
.........and Snowbeard
I ended up using a magnet on a stick to hold each one in place with the cover just a half inch up, then push each rocker down onto them to hold in place and seat the box.
Never used a magnet yet, good option.
Something I noticed just now though is that the Exhaust rod cups are visible over the top of the rocker shaft if the adjusters are wound right back and sitting on the valve tip, and the inlets opposite, still wound right out, but way off the valve tip, are real easy to see (as you probably know).
Admittedly it's out of the bike, on a (bench) and relatively easy to see and no frame in the way, but Ive done it in situ and still a bitch, but not that bad, and with a small mirror ('virtual magic') may just be ........?.............easy?
Also small digital surveillance cameras/monitor can enhance that 'virtual magic'- I've used one for bolting a tie down eye bolt in where I couldn't see.
I was looking for info re-rocker shaft shims Might be a different topic will have a search or start again
