Granted I only have 150mi on it, but is the B12 a hard starter? It takes several seconds on the starter to get mine to fire over, and that's with the choke on.

Is this a normal thing, or is an adjustment in order?

Is your bike completely stock? In stock form they are lean which can add to start and warm up times. You might want to check your choke linkages and make sure they are operating properly so you're getting the full choke at cold start.

My 05 is the same way but.... if i only do half choke its alot better. Starts in half the revs.

Ya, If I use half choke it starts ok, but it sometimes dies even when the choke is on.

Ditto #2

But if after a minute its starts to run rough and wanna die...then just touch the choke down alittle further. Then the revs come up and it runs smooth. After about 30 seconds then its choke off.

So what if I jet a stock B12, will it improve anything?

BlkJello · « **Reply #6 on:** September 02, 2005, 05:01:42 PM »

Another thing i found is when i first got it...my buddies would come over to check it out....i would start it for a min for them to hear it, then would shut it off. If your doin this...its a no-no. Fouls the plugs. Mine after a couple of times started running like crap.... I replaced the plugs and walla...all better.

Supposedly yes it will run better...even with the stock can.....they are setup real lean stock. Once in awhile i notice a very subtle pop here and there on decel. Waiting till i can afford a holeshot 21 slipon till i do jetting though.

ok, so what's a good jet kit for a bone stock B12? How much does a kit run?

BlkJello · « **Reply #9 on:** September 02, 2005, 05:20:07 PM »

Well it looks like the holeshot stage 1 kit is about 160-170 bucks. But Dale recommends it with a slipon. Although ive heard of quite a few people using a jet kit by IVAN. Not sure how much they are though.

No prob

Theres a sticky in the 600\1200 faq about Ivans and Holeshot's stage 1 jet kits.

On mine, using the choke, I also have to turn and hold the throttle open for like a half inch, then it starts immediately with no dying afterwards. Hard to start at all without holding open the throttle that little bit.

My 05 seems to start easiest when at about half choke, then when it fires I throttle it up to about 2700-2800 rpm's for a few seconds. It's golden from there.

It doesn't get real hot very often here in my part of WA, even summertime temps rarely break 90 for more than a few days. When it does get 80+, I find I usually only need ~1/2 choke to get a quick and easy startup, the rest of the time, it's full choke to get her lit, followed by a quick trim-down to 1/2-3/4 depending on the day's conditions... this is to get her to idle at 2000 rpm (like the owners manual says). I then go thru my routine of inserting earplugs, donning the skid lid, then the gloves while it warms a little, turning the choke down during the process to keep the idle near 2000 rpm. By the time I'm ready to ride off, the choke is nearly shut off. I ride off like this and after the 2nd stop sign from my house (~1/4 mile), I turn it off completely. If it's cool out, she'll still hesitate a little if the throttle is whacked right after the choke is shut off, but I don't have another traffic control for ~10 miles, and she's always golden within 1 1/2 miles, no matter how cold it is out.

I've read many posts from folks in warmer climes that don't have to use any choke at all in the summer, even on bone stock bikes, but mine has always liked at least some, no matter how hot it is when the engine has sat long enough to be considered 'cold.'
