Thread: vvl valve shimming "how to"?

with the increasing popularity of aftermarket VE cams, i was surprised to find no "how to" re-shimming write up here on the dash.
Greg did a write up on swapping in N1 cams and doing the springs/retainers which was great. but no re-shimming is required for the N1 cam swap.
anyone willing to do a write up?

thanks,

Ric S.

Toss a feeler gauge in between the cam and the low lobe rocker.make sure there dry no oil. And replace the shim to make proper clearence. Very easy just takes some time

So the 184c's needs re shimming?

Step by step to make this as simple and painless as possible.

Install cam with all rockers and shims in place. Take initial measurements of all the clearances and write down on a sheet of paper with a drawing maybe to make it easier.

Whatever rockers are out of spec see just how much it is out of spec by taking your desired clearance and the clearance you got and subtract them, get your difference + or - dependant on if the clearance is too tight or too loose. Remove the shim and measure the shim one at a time for the ones that are out of spec. Then take your numbers + or - and you need a shim that much thicker or thinner to get the desired clearance. Install the proper thickness shim to get you within the desired spec.

It usually gives you a range so anywhere in that range is good. Specs can be found in the VE specs sticky in this section.

It just takes some time. Maybe one day we will get some aftermarket rocker arms that have an adjuster on it like the hondas. But i doubt it. haha For now we are stuck with reshimming.

man this quick write up that u did was cool.... u shoulda just dropped in the range

i was talking about the spec sheet gives you a range to be in for clearance. lol Not just throw it in the range of whatever.

Also you can get the shims you need at the Harley dealer. Vrod shims are the same size as the VE. They have them in different sizes.

yeah i know for when they are hot and expand and cold to go back to normal. just saying u shoulda just posted the acceptable clearance range

OEM gives an accepted range. Kelford does not. .020 intake and. 040 exhaust iirc

Factory is .009 on the intake and .013 on the exhaust (+/- .002)

Is .020/.040 what kelford gave you Cory?
