And yes, the 'c' lifters are junk. Problems with the hardened roller flaking or chunking where the hardened outer surface comes off the roller. Not only does the lifter fail, but it sends those metal flakes out to circulate your engines oiling system.

 

I'm going to replace my lifters with gaterman lifters if I don't do a 107 kit from Fuel-Moto first.

 

When I swapped out cams my lifters had lots of hydraulic integrity. It took them a good long time to bleed down during pushrod adjustments. And as I ride and listen to the various noises eminating from the 103, I don't hear anything that signals any kind of alarm.

BUT, to be on the safe side, I have ordered the Gaterman 1023 lifter set, latest version, to have on hand for a lifter swap-out project later this year. I am not sure if I have the C version in my 2010 or not, but whatever it is it wont be in there for long.

Here's a link for the Gaterman lifters if you are interested in learning more:

The Gaterman products are not totally US made as I understand it, but when you start looking at our bikes and see Japanese front ends, Italian brakes, and Canadian bearings, well you get the drift.

Woods directional lifters are out there as well and claim to be made in the US, but very pricey and not sure they are better than that of the Gaterman offerings which are significantly less costly.

So if there are people like me that would like to improve on longevity but not worried about power increases can I just change the lifters and use the stock push rods?

 

Yep, and here's a good one to consider:

Not true.

We grew up with cars that maybe lasted 100,000 miles. Now 200,000 is more the norm. ( My wife's 2006 Altima just turn 130,000 miles and only needed a crankshaft sensor ( $30,) at 100,000 miles. Still runs rattle free and uses no oil.)

Harley makes them cheap now because on average they don't get ridden much. The new management recognizes this. If Harley made cars, they'd be out of business. Remember the Yugo?

Harley survives because (and only because,) it has a captive audience.

 

I'd steer clear of the comp lifters. Experienced hot bleed after a mere 3,000 miles.

 

Thanks for the tip

 

Yes you can. However, remember that you will need to pull the rocker covers to reuse stock push rods. If you replace with adjustables, you can cut the old rods out with bolt cutters and replace with the adjustables without pulling the covers.
