Hello,
I'm considering a 95" build with the stock heads, SE flat top pistons and a SE-204 cam on my 2000 FXDX (carburetor).
I really need some help with my questions regarding the optimal build and use of this combination.
I really like the all around characteristics of the stock 88", wide power band and smooth just want more power preferably
all over the band but would prefer less HP than looose the torque low down.
On this forum I read that the 204 is also used on heavier machines (RK etc)
I ride my FXDX most of the time 2-up, we are both around 150lbs ; total 300 lbs.
- Is this considered to heavy for this particular cam ?
Driving style is mostly conservative 1900 - 3500RPM , but occasionaly fast using the whole RPM range.
What is the optimum compression for the SE-204 and what does this mean in practical terms ?
According to the HD catalog the compression would be 9.4 :1 using a cometic 0.30 gasket this would rise to 9.7 : 1
if I'm not mistaken.
Higher compression option (9.7) means:
- more/less HP ?
- more/less heat ?
- harder/easier to start ?
- more/less torque low down ?
- Is it possible that the Torque low down would be less than the stock 88" ?
- What about detonation ?
- Is there a dyno graph of this combination available, I looked everywhere and don't find this basic
configuration.
- Would I need an oil cooler or can this wait for later ?
- Is the S&S IST ignition a good choice or overkill for this mild build ?
- What would be the recommended SE ignition ?
Some people mention that the SE-204 creates 'couching' effects in the carb below 2000 RPM.
- Apparantly this is a side effect of the timing of this cam. Does this affect riding ?
Is there someting wrong with the SE-211 Stage II build in the Harley catalogue, SE211 with
HTCC head, HTCC pistons and HTCC intake ? From the dyno graph I would say
this is a smooth combination, nevertheless I don't see many people using it.
Lots of questions I know, thanks upfront for your using time.
