Andrews EV13 cam installed: Nice
The lad and I just put an EV13 cam in our 95 RK and couldn't be happier. (Him doing all the grunt work, me site supervising from comfortable chair.)
It's a two-up touring specific cam and is just what the old boat needed.
A good dose of extra low-speed grunt and absolute gobs of extra mid-range power. I've never hit the rev limiter on this bike - never any need to -- so can't comment on top end but it seems to pull well up to as far as I am prepared to rev it. (No tach on this bike).
Plus the bike seems to run better all round, idles better and even sounds a little better. (Staintune slip-ons, they have that farty stainless sound anyway)
Overall, very nice indeed.
Not surprising I guess, seeing as the stock cam had no valve overlap at all. Unbelievable!
Now blitzing past cars and trucks on steep uphill twisties and having lots of fun.
While the bike was up on the hoist, we put on a Progressive Touring Link track stablizer thingy between the rear of the tranny and the swingarm pivot plate. Seems to make the bike feel more "seated". Maybe a tad more vibration, but it's so little and so subjective, hard to tell for sure.
I did notice the Progressive swingarm pivot plate stuck out a gnat's whisker further than stock and had to make sure the zorst pipes did not hit against it and transmit evil vibes.
Had a couple of narrow escapes while changing the cam. One was noticing a couple of teeth on the plastic breather gear starting to deteriorate, so slipped a nice S&S steel job in there. Seems like anything rubber or plastic on bikes over 20 years old starts to give out from age rather than mileage.
We put a pair of new umbrella valves in the heads while the rocker boxes were off for the same reason. The old umbrellas were hardened and not working at all really. Seems to be the cure for the oil dribbling out the KN air cleaner , so far.
A good time was had by all.

So far, I haven't changed them for the cam.
I already had a K&N filter and slip-on mufflers and some time back had put a CV Performance kit in the carb that included new needle, spring and larger jets. From memory I ended up with a 46 slow and I think a 180? main but will have to check my notebook next time I'm able to get out to the shed.
I never could get it to run as sweet or strong as I would like but since putting the cam in, the carb set up seems to be spot-on so i am not dicking with it right now.

I wanted to put a EV-13 in my bike years ago, but the shop I was dealing with tried their best to talk me out of it, claiming I'd "never feel the difference."
I'd still like to try one, but I don't dare put a new cam in a motor with 100,000 miles on it. It would probably blow up in a week.

I bought my 97EG as a project bike with a vibration I thought was an easy fix. It wasn't but that's another story. I had thought a good many times of just dumping the bike because of the vib. I found 4 evo's I test rode to buy. I just never found one that I thought atleast performed as well as mine did.
So I'd go back trying to fix mine and finally got it right.
In all this I found a EV13 had been installed and some head work.
Ok that's why it runs like it does, it added to my resolve to fix this bike.
I too like the low end grunt. Great for pulling tree stumps
