    Clarke 4.3?

    Must depend where you have your fan mounetd because both myself, and my buddy (using my 4.3 Clarke) easily fit the SPAL fan behind the right rad.

    Our fan is mounted between the emissions tabs on the back of the fan. I could dig up a picture with enough searching.

    You rotate your tire/wheel backwards to get to TDC?

    Dunno yet but I'm estimating 3 times that going by memory of what a Joe Racer e-start used to cost.

    I don't really know what the actual weight will end up being since the new Lithium batteries will shave a few pounds off.

    Me too, if the price is similar to what Baja used to sell them for. I don't want to pay more then the next guy but there is a lot involved when putting these things together.

    I'll keep you all posted on weight and price as soon as I know more.
    In the meantime, mine kicks over first kick every time, it's when it's vertical, hot out and your exhausted that makes you want the e-start.

    Stay away from the primary drive chains too. I love rocky mountain atv, but a hundred or so pages back you will see my broken crank case caused by a pd chain that failed premature. Also, when I posted my review of the pd chain on rmatv explaining how it cost me over $2000, rmatv gave me my money back (for the chain, not whole motor) and deleted my review. I got paid off and didn't even know it. Bastards!

    Yeh, I was scratching my head on that one too.

    Anytime the crank moves backwards the decomp kicks in, correct?

    Gents,

    Quick question about coolant temps in colder weather. I've noticed that my coolant temps aren't getting past about 135 to 140 degrees according to my Trailtech Vapor computer, in the mornings, when commuting to work with ambient temps around 50 degrees. My commute distance is about 7 miles on arterials. Anyways, I let the bike warm up for about 30 seconds or so before leaving in the mornings; maybe I should let it idle a little longer?

    Will my temps being so low cause any long term issues? Otherwise, the motor runs just fine and pulls like a freight train.

    Thanks!! :freaky

    Yes please, I'd be interested too.
    If price is right (ie not over the top) I'll buy it in a heartbeat.... but probably and hopefully will wait eons with actually mounting it.
    This bike I'll never sell, and once old/ancient and dilapidated I just might want to have the option of mounting the kit then - if I'll remember it, be free of Altzheimers that is.
    Now, what were we talking about?


    :rofl
    Serious, keep's posted on the price, an better tell the weight-gain to someone who cares a bout that :lol3

    You're not alone, in fact I think Larryboy is deadwrong here.
    You only may rotate backward if the auto-decomp system is inoperative, so with a HRC-regrind or maybe also with Stage 1/2/etc hotcams? Definitely not with a std cam, it'll lift the one exhaust valve immediately.
    Pls note Medisyn?


    Larryboy, you have no habit of posting wrong info, contrary even - you're sure bro? :eek1

    Never really thought about it, I have always done it that way. If I'm wrong, I'm wrong. The decomp activates under low rpm like a kickstarter going forward, I roll them around backwards with the rear tire, always have.

    I will follow your advice. I have done everything other than check compression and raise the float to 18mm. When I am rotating the crank by hand counter clockwise I do hear a click, is this the decompress kicking in? I am wondering if I have the left side exhaust valve really off. I never turn the crank clockwise.

    While I have not used a gauge yet there is signs of compression. Putting my finger into the plug hole will result in it getting pushed out on the compression stroke and the kick starter gets hard/immovable at/near TDC. I always have to use the decompress lever to get it one click past that so I can kick it. Thanks everyone for the advice. I know I will get it started if I just stay determined! :D

    Sounds like your stat might have failed. Mine was doing the same thing. See my post a few back with a pic of my stat.

    Damn. I heard a BD one on ebay went for under a 1000 awhile ago.

    I'd like to buy one and keep it in storage if I ever wanted to build a supermoto, but at that price I'll just keep kicking :rofl (only takes a kick or two to light the beast up anyway).

    I was referring to SCREW SET B, part #10 in the carb parts fiche. When I re-jetted, I set the pilot screw two or three turns out (or what ever was normal for my jetting) and once I gave it enough gas though the throttle stop (idle adjuster) it started easy as pie.

    Guess what guys, after messing with the float height and getting a buddy to help push start it it FINALLY fired up. It felt so glorious for it to actually start. A messed with the idle screw a bit and turned down the idle a bit and shut it off. I was able to restart it after a few kicks after.

    The valves sound great. Very sowing machine like. I think it will still take some tuning to get it easier to start but for it to actually start is pretty huge for me. Thanks everyone again. Thank you all for not telling me to fuck off several pages ago.

    I am noticing it seems like the clutch dragged a bit when I had the clutch in all the way. Seemed to go away after the push start...

    EDIT: After the bike was sitting for about an hour I was able to kick it to life with no choke with two kicks. A good sign!

    See, there you go! Tune the idling circuit as per above and it will start with one kick - after having cycled the kicker twice of course, to 'clear its throat'. I'll admit you must get used t that but that will take all of one day's riding, so go get yet butt out there. Enjoy this bike, it has very few equals if at all.


    And Larryboy, if it worked for you then it did, no sweat. I just though to mention it to Medisyn as he clearly had to do some logical checking, and then failsafe is best.

    congratulations dude!!! i have been following your posts and, as always, have learned much and have appreciated all of the help and technical info provided by the adv inmates.
    the pig is still a fairly new bike for me and it is frustrating as hell when you can't get it started. for a week i couldn't get mine started, then one day i checked the valves, looked at the plug , and changed the oil and it fired right up. go figure. valves and plug were fine.
    looking to get some tires that are more pavement oriented for the spring. any recommendations would be helpful.
    happy fall riding everyone :1drink
