New guy - DRZ Power? Battery for easier starting?
Posted 06 March 2012 - 01:30 PM
I've had my '03 DRZ 400 for about three week now and have been having a blast with it. It is sure a step up from the '90 DR250S I wreaked havoc with in high school.
The guy I purchased the 400 from was a real connoisseur and had done most of the upgrades on TT.
My understanding is that there are four basic models: Straight-Z (mine), E (elect start), S (street), SM (supermoto) and that the E and Straight-Z have almost the same engine with the only difference being the flywheel. The S has a less powerful carb/cam setup and fancy stuff like turn signals.
This site (http://www.bikez.com..._400_e_2003.php) puts the E at 48-hp but doesn't mention power for Straight-Z or S. Other sources I've come across put the S at around 42-hp. Does the "Straight-Z" make 48 stock? Following some of the posts here, it seems like quite a bit has to be done to break 50HP. Are the numbers I quoted engine-HP and everyone doing mods talks in rear-wheel?
Other question is this: I don't yet have a great feel for where this machine likes the choke & throttle set when starting. This results in me kicking...well...quite a few times. If I were to add a small capacity battery to power the ignition system when I'm starting (I'll isolate the headlight), would that help make a hotter spark and make for easier starts? Thinking about adding a cig-lighter and usb anyway and would like to have a few watt-hours available with the bike off (If you aren't charging your iphone, you should be). So the easier starting wouldn't be the only purpose this would serve. Thoughts?

DR-Z400E (electric start dirt bike)
DR-Z400S (dual sport bike)
The kick start model and E (with the FCR carb) were same HP. Some place in the high 30's
All other models are maybe 35 hp.
40 is easily achievable. 50 takes some serious mods. I think Eddie the DRZ expert is up to 60.

Technique for cold start - gas on, choke on, turn the throttle once or twice to squirt some gas (this is where you may need to experiment), Don't touch the throttle, kick.
Hot start - don't touch the throttle, kick.
Real hot or flooded - Pull the hot start plunger, don't touch the throttle, kick.
