    just an update for you regulars -

    I did finish the HC piston last Friday. Test rode local gravel roads on Saturday to break it in.

    She ran a good bit hotter, hopefully it settles down a little as it breaks in but I'll probably be putting a KTM fan on the oil cooler.

    first impressions: I did feel an improvement in the throttle response and believe it was a little smoother. I was neither overwhelmed nor underwhelmed by the increases in power. It's definitely snappier but I kind of expected more. For the $200-ish cost of the DIY upgrade it wasn't bad. Further testing on the trail will be needed to get a better idea of the power and heat tradeoffs. Before doing the piston change, I believe I read somewhere on the web where someone compared the change as similar to the gains felt with the pumper carb. I think I would agree with that.

    I did have pinging at low RPM loads. Down where she used to tractor, she now pings. I had a half tank of regular gas and attempted to put some premium in it at the station. But the local pumps only have one handle for three grades so by the time you select and pay for 1.5gallons of premium, I bet I was lucky to get .5gallon of premium in the tank.

    I will probably fiddle-fart around with the carb jetting some more to see if I'm still in the sweet spot.

    I have both, love them both. The issues your buddy had are well known with simple fixes. After lubing my stepper motor, I've had no more idling problems and don't expect any more. Mines been as reliable as my DR. The Tiger is NOT a dirt bike though. This ride turned from bad to worse, with steep rocky descents and ascents. I got through on the Tiger OK, but would have been happier on the DR. I bought the Tiger primarily as a road bike, but one capable of continuing on when the pavement ended, not a trail bike.

    If you can hear it, it's bad.
    You could pull the timing back a bit.
    Certainly a lean mixture will contribute to the problem, but correcting that (if it's the case) won't likely solve the problem alone (since DR's have been reported to audibly ping/sustain detonation damage with a standard piston).

    1. get a regular (and cheap) lead acid battery, stay within your budget.
    2. Stock tanks are available everywhere ... cheap! Get a new one. So many here take off the stock tank first thing. Check the Flea Market everyday.
    3. Lots of other parts can be found here (Flea Market, Parts, search DR650)
    4. The cheapest, easiest and most effective headlight solution is the DDM Tuning 35W single bulb HID kit. Plug and play, 3 times more light. $30.

    Hmm... How would you suggest TinkerinWstuff do that?

    Considering your past behavior toward me, I do hesitate to answer.

    He can install an offset key, slot the pickup mounting holes & move the pickup, or install a programmable ignition.

    :D more light less power?
    where do i sign :D

    i have bin throwing back and fourth the idea of just getting the oem battery again.
    my bike is an 02. its still the stock battery even AFTER the owner wrecked.
    and it barely stopped working a week and a half ago.

    thats nearly 10 years of life.

    if i can get 4 years out of a battery its a blessing.

    10.!!

    people should write stories of these magical devices.:thumb

    but i would like a direct comparison of the DDM's vs the stock headlight.

    procycle has a very good comparison of there HID kit.

    if its anything like that. i'll hit the take my money button as soon as i see the photo's.:clap

    where do you live?

    The main drawback of the new Li batteries is apparently they die quickly and don't crank when the weather is cold.

    I'm in NY and it's 20 right now, so that's not an option for me.

    Otherwise I'd love to ditch that fat battery!

    switched back to my OEM size wheel and stock gearing for a better perspective on the HC piston. Now the butt-dyno can see more of a difference.

    Last fall I switch to a 120/80-18 rear with 46T sprocket for single track. Lucky if I have an hour on that setup so it's tough to gauge things.

    On the OEM setup, I'm still not blown away but can see more of the improvement. Runs 80+mph easily and lofts the front wheel in 1st (at 5000ft elevation and with the FCR pumper carb)

    Temps are stabilizing a bit but still running 20-40deg hotter on oil temperatures. 55 or so ambient temperatures today and running 60mph highway speeds, the oil coming out of the cooler into the head was running 240. Stop and go in town and it's nothing to see 265+. According to the Vapor.

    Fulltiming in an RV! Currently NW Oregon

    I have a Ballistic Battery 8-cell in my FZ1 and it's a total PITA in cold weather. I have to leave it on the battery tender all the time in order to start the bike on cold mornings. Otherwise it just runs out of juice trying to get it to fire. The alternative, according to Ballistic, is to turn the key on and let it sit for 5-6 minutes. Sorry, I don't have time for that when it's 26-28 deg. outside. I want the thing fired up and heating my gear.

    I'm going to move this battery to my KLX250S, which really doesn't ever get riddin in cold weather, and put a regular battery back in the FZ1. It's already 2x the size recommended for the KLX (and still 5-6 lbs lighter) so it should be fine there.

    I've always had the best results w/ Yuasa batteries, not the cheapest but they are reliable and long lived. So far as the light output goes the first thing to do is add relays with a fused feed direct from the battery, the stock wiring typically drops 2 volts or so which will cut light output nearly in half and a high powered bulb would make the drop even worse. The relays are cheap if you go DIY or you can get a quality kit from http://www.easternbeaver.com/Main/Wiring_Kits/H4_Kits/h4_kits.html
    I installed relays and a plus bulb in my own bike and the lighting is not bad at all now ....also FWIW the stock reflector and lens are glass and can handle the added heat of an H4 plus or high power off road bulb OK

    That is interesting, I haven't heard of pinging on a stock setup. Thought I read up on this one pretty thorough before going forward but didn't see any of those. Did you see that on ADV or somewhere else?

    I added some octane boost to get through this tank and it helped. The only time I got pinging was when my oil temps exceeded 270 for a moment.

    I did not see anywhere else that people had to adjust timing for the HC piston. So I'm tempted to leave that as a last resort.

    Ran out to the garage and measured my 2006 take off springs. Put new heavier springs front and rear a while back.

    stock fork springs= 1 3/8inch OD and just under 22inches long
    shock spring= 2 1/4inch ID and 10" long

    Hope that helps.

    As I said, if you can hear it, it's pretty bad. Enough detonation can be present to damage the engine without you ever hearing it.
    See http://www.advrider.com/forums/showthread.php?p=10906911&highlight=detonation#post10906911.
    Increasing exhaust flow would also help.

    I regularly get 10 years or more out of a battery, especially a quality one. I do it by keeping my bikes plugged into battery tenders anytime they're not being ridden :thumb

    I live in southern cali. it doesnt get TOO cold here but lately its bin dropping down into the low 30's which is somewhat rare.

    it hasnt bin getting its normal semi warmer weather lately so im worried about the heat of the DR650 killing the battery.

    never had to worry about the cold weather.

    this bike almost always starts first click of the starter regardless of weather.
    or battery condition. the day before the battery took a bing steaming poo. it still started up just fine.

    I didnt think it dropped that much voltage. maybe i'll wip out the handy dandy voltmeter and see how many volts its dropping through the circuit out of curiosity.

    if its loosing that much power i'll definitely rig my own circuit up with relays and probably go up a guage in wire.

    i dont know if this is a stupid question but.

    what is the MININUM CCA needed for the 650.

    the stock battery has a CCA of 120.

    that seems pretty sad to me.

    apparently i can get a powersource battery for cheaper than the oem.
    and it puts out 175 CCA its not much of an improvemt but for cheaper and higher CCA.

    maaaaybe its worth the investment?:hmmmmm

    im just throwing that out there even though im going tomorrow to pick up my yuasa

    Bold statement. but what brand for what bike/car/jet ski/ time machine?:ear

    because i normally get 4 years out of a battery this is the first time i have EVER gotten 10 years out of ANY battery regardless of brand,size,configuration:cry
