So cam.. I’m thinking at 30k miles I need to open it up and at a minimum replace the INA cam bearing, and while in there why not do a cam upgrade. Seems like the standard choice for an otherwise stock motor in a light bike is an EV27. I’ll do S&S lifters and pushrods as well.

I was planning on running the S&S metal breather gear/valve but I’ve read it’s better to leave the stock plastic one as if it flys apart it won’t spread metal. Is that logical?

Also, any cam recommendations other then the Andrew’s?

 

Wood W-6 is a good cam especially when you bump the compression to 9.5-1 or 10-1. A set of S.E. heads with .030 Cometic head gaskets will get you right in the sweet spot.

 

Excellent advice. However I’m not opening up the motor. Just a cam to pep it up a little.

 

I'm curious to see what cam you go with. Sifton 143 is my first choice and Andrews 27 or Woods 6 are my second. Problem is finding a good Sifton cam since they aren't being made now.

 

27 is going in next week. Gathering parts right now. Fueling HP+ lifters, S&S breather gear and cam ordered. Going to go in from the top so will reuse the stock pushrods.

BTW, Do you clean or replace the tappet screen?

 

I'm doing mine this winter so I'm gather parts as well. I'll probably replace as much as I can for peace of mind. EV27 seems the "go to" cam, I'm leaning towards this choice as well. I hear/read Woods 6 is strongest but also hear it's noisy. I use to have the Sifton in my softail back in 89' and it hauled ***. S&S E, Dyna ignition, Thunderheader and Sifton 143 was the combo back in the day. Keep up posted, looks great

 

That is the setup I'm running with a Mikuni HSR42. Seems to be good but it's still an 80" Evo.

. I bought it to do oil changes in my E550 through the dipstick tube, but it has a great brake bleeding feature as well. Simple and fast.

 

I had a Lieneweber E31 in my old Evo chop. That thing was a bullet. Super E and some S&S pushrods, Crane Hi-4 and it was an 80" wheelie machine.

 

I put a Vthunder evl 3010 in my FXRC, its between an EV13 and EV27 and runs quieter a EV27
