Looking a having 103 stage four done on 09 glide, any comments positive or not? should i go with screaming eagle kit or is another vendor better, with better dyno numbers and for the dollars? any insight would be great

 

What ever you decide to do, it best to have your heads done or buy a kit that has heads with compression release. I did the 103 StageII with the 255 cams and had to pull the heads back off to have compression releases installed after ruining one starter. No problems since having the releases installed

 

Depends,

Do you want a kit slapped together from mass produced off the shelf parts that consistentlty produce low power, put together by a dealership that make their living by selling underpowered bikes and bolting on chrome goodies and selling tshirts?

Or one thats put together by someone who is in the business of making serious power on vtwin engines. Consisting of parts chosen to compliment each other and machined to exacting tolerances that will ****** a knot in your neck everytime you twist the wick?

 

Talk to an Indy. You will be glad you did. I cant speak highly enough of S&S. Check out the pics of the kit in my album....

 

When I did my Stage III, I consulted a few guys on a high performance forum that where a lot more knowledgeable than me. They were very helpful and steered me straight. I also spent a couple of weeks reading cam specs. Then I had a series of conversations with Bean at BigBoz Heads. Bean was extremely helpful in helping me match compression ratio to cams and gasket. He was very patient in explaining squish but I'm still not sure I understand it completely, but it works. I had a good indy wrench put it all together and the local dealer put the finial tune on my PCIII. My bike is awesome and a real head snapper. If I had it to do over again I'm can't think of anything I would do differently.
Take your time, study and have fun.

What are they telling you stage 4 is?


Stage 1 is intake and exhaust.
Stage 2 is cams + stage 1
Stage 3 is heads + stage 2

Big bore is not a stage, it's just big bore.

Stage IV is in the SE racing catalog it consists of heads, 103" jugs, cams, adj push rods, 58mm throttle body, auto comp release, gaskets etc.
I think I got it all.

 

I had the "SE Pro 103" stage IV" kit installed on my 2008 SG last winter. Dealer made a good deal due to slow work load. I think the kit retails for $2400. I got it for $2300 including installation. However be aware you still need to purchase gaskets, fluids, compression releases and compression release wiring harness. I subsituted a SE 251 cam in my bike. With a V&H pro pipe, it made 104Hp/106TQ SAE corrected. Dyno tunes by Brian at T-Man performance. After 1500 miles, I took it all back out. The forged 10.5:1 pistons, Large valves and springs in the 110+ heads made more noise than I was willing to put up with. I had adjustable pushrods and was running lot of preload. I had several people listen to it. Everyone said it sounded normal or O.K. but I didn't like it. The 58mm intake with large injectors are over kill for a street 103" engine. After returning it back to stock it's all quite again. I personally think the SE kits are good for someone on a buget who is not concerned about max power. But more power can be made using your stock heads reworked, your cylinders bored and a good piston, cam and a good fuel management system.

 

For the life of me, I can't understand why people still try and put all SE builds in a lunch box of crap along with the dealers that do them. There are good choices out there on all ends and it depends on all the parts and who puts it together. Do your research and go with what you feel good about. You can read about my build to get an idea of what is possible with the SE 103.(link in sig) You can find other builds as well to read about and then decide what is best for you. Good luck with your build.

 

One of the reasons I think SE is not the way to go is warranty. My stealer wanted $13k aussie to build an SE113. And it didnt have gear drive cams or roller rockers for that price. When pushed the manager admitted that the engine is for race purposes and has no warranty.

My S&S motor has a 12 month unlimited k warranty.
