Maybe a dumb question but going to ask anyway. I’m setting up to do a cam upgrade. Bike does have a a lot of miles from last season but always change oil in the spring regardless. Should I wait till after I change cams to put fresh fluid in? It has amsoil in it now with maybe only 2500 on it from last season but has been in winter storage since Nov.
if I should change it first should I use Dino oil for the initial change with new cams and other new parts or does it matter?

 

Change to some less expensive Dino for the first 500, then just go nuts on whatever you want if it ain't gonna break your financial reserve! That's what I would do.

 

I wouldn't expect cams to be a wear in item like rings. If it is time to change the oil it is time. Do the two together and go ride.

I would take it easy for a few miles and then check the engine over for leaks and whatever. After any work ride cautiously for a bit is my approach.

 

Thank you

 

You won’t loose much oil doing a cam change. You can’t go wrong with new oil and new parts. Change it before the work, then after it’s back together check oil level and top off if needed.

 

Good plan. Thanks

 

I will be the outlier. Assume the OP is replacing the inner cam bearings along with the cams, new lifters and maybe the chain tensioners; not sure what the cam chest looks like now. Use cam lube for the cams and lifters and dump everything at 100 miles for new oil and filter; ride on.: The TC motor is not that sensitive.

 

hey Don,always appreciate your invite and input.
while I got ya on the line will ask another question. I’m going to remove and inspect the oil pump as well as remove the pressure relief valve and spring. Because they are cheap I intend to replace the oils pumps wave washer and relief valve and spring.
is it necessary to reseat the new valve or does it just drop back in. Saw a video where they “use a set punch and give it a good whack with a hammer” seemed kind of caveman for a precise engine part but what do I know.
thanks again

 

Are you expecting flakes of metal coming off the new parts?

Is your thinking you will see if the new parts are good?

 

As djl says........ Assemble camshafts, lifters and cam bearings with assembly lube. There is an annealing process to the camshaft and the rollers on the lifters that is necessary to protect the motor long-term. Have seen cams that are not hardened properly and will wear improperly..
