Here is my set up. I have the SE pushrods and the tpi is 24. Woods lifter with 777 cams. What is the correct adjustment from zero lash?
I'm getting a bit of top end noise and wounding if I have them adjusted properly.

 

Generally the lash is set at .120/.140. For your pushrods, that would be 3 -3 1/2 turns. Make sure your cams are on the base circle.

 

Thanks QC. I have them at 3 turns now. Thinking I will give them another half turn. I wasn't sure my math was right so figured I would ask on here.

 

Good luck chasing that noise!

 

What year is your bike and how many miles? On one of our bikes, a 2001 RKC that now has 53,000 miles on it I chased valve train noise for years. I had a 95" big bore kit and cams put in at the dealer when I bought it new. I can't remember when it developed the noise, tapping etc., but it was years ago. The timing chain tensioners have been replaced once at about 35-40k miles. A few years ago I pit in Crane lifters and Fuel Moto adjustable punch rods thinking the original lifters might be the source. But that really made no difference. I tried stethoscopes and other ways to isolate the noise but could not find it.

Finally this week we put in a set of Rockouts on the rocker shafts. Just started it up an hour or so ago and the noise seems to be gone. It is raining hard so we have not ridden it yet to really test it. Assuming the noise is gone it will be a great investment of $15.00 and a couple of hours of labor.

 

Lol!! Already have the rock outs installed.

 

My understanding is Woods cams and lifters can be a little noisy.

 

Wood cams are a little noisy

 

So I checked the push rod adjustment tonight and I already have them set to 3 1/2 turns. I'm thinking if I back them off it will only make more noise.
Anyone have any input on this?

 

I actually just went through this myself and found that deeper is not always better when it comes to lifter pre-load. My pushrods are also 24 tpi and I had set them at 3 1/2 turns and the lifters were super noisy. I started over and set the pre-load at 2 turns and 5 flats and the noise was drastically reduced. My guess is that the reduced oil chamber between the piston and the bottom of the lifter (less oil) causes more noise on some lifters . If I were you, I would set them at 2 1/2 turns. Go by your lifter instructions but most will want the preload set at the mid point of the piston travel. If they are noisy after it gets hot, go another flat or 2. I think some lifters respond differently than others. Make sure you do this when the engine is cold (sat overnight). Keep us updated on this.
