I got EHS's Big 3.

Whats next. Small increments please. Don't wanna do A B C D all at the same time and it be 2g's.

I keep seeing threads on Hot Cams and +3 TB's.

Is that next?

A friend of mine has the big three as well and the stage three hotcam made a significant difference with the power increase.

No the hotcam is gona be your next bolt on step. The big bore is gona require you to have your cylinder bored to fit a larger piston. I would just go with the cam for now if it were me.

i got a stage 3 hot cam and the EHS big three. Made a pretty good difference up top. I would suggest getting a 11:1 cp piston at the same time.

Now would I need to get a mechanic for that or something any decent "engine guy" will be able to help me throw in on a saturday afternoon?

Also, I keep reading for slightly modified bikes a stage 2 cam is better???? Sorry for the 100x questions I am just trying to make the right decision.

Most of my riding is done between 2-4 gear. Alot of trail riding so I don't want to loose much from the bottom half.

your going to get most of your power from porting your head. the hot cam is a easy drop in that doesnt require new rockerarms or valve springs. next you can get a higher comp piston 11:1 12:1 13:1(11:1 is safe to run on pump gas 91 oct) the other require race fuel. and the +3tb will also add a lot. personally i did mine all at the same time because i did not want to be tearing down my motor everytime i got a new part just saved up and did it all at once. but it is perfectly fine to do it little by little.

you should get your head done, thats where all the power is at.

Pretty sure HDD has a +2 +1 P&P head, Web 290 cam, and springs/rockers right now, so you wouldnt have any down time.

I got the stage 3 hot cam for $135. According to EHS's dyno it added about 5hp over just the big three. I didn't notice any loss on the bottom end. It would probably be best to get the piston done at the same time though. Ported big valve heads are sweet but expensive. Even a stock valve port is gonna be around $250.

Get the head first then do a little at a time as money allows. Figure out what your long term goal is, if you want a P&P head now or in the future IMO don't waste your money on a Hot Cam now. The Web cams perform way better than the Hot cams do in a ported head build.

Put a cam in it, that would be the best bang for the buck single mod at your build level. When the piston comes out for an upgrade then I would have the cylinder head ported while it was off. This is what I would do if I was building it one mod at a time.
