starting cold bike 2 Years, 4 Months ago  
Good morning all I have had my star for 18 mon. Ive done the oil changes, blinker mode, pulled the whole front end off for shock oil change witch was black,had a new avon put on the rim by a local independant shop bikers bay in lake jackson nice shop and good people worth driving to for your work they will tell you up front if your bike needs it or not. this is my problem do all 07 bikes need to have the choke out to start and keep running or is my bike just set at too low of an idle. Ive also installed the maxair tps thumb screww it is set or was at out 2 1/2 the bike runs good and on hard decelleration it pops very little and not loud. Do yuall think I need to go out 1/2 a turn or just set the idle up a little. thanks to the tech. setion all my work has been done through that info.

very normal, be glad that the choke is needed.. Just gradually reduce choke as it warms up..

Some will disagree but a well tuned engine will pop on hard deceleration. If you need to keep the choke out while riding ie... the engine is totally warm yes you need to turn the idle up.

Sounds like the enricher is working the way it should. Full to start. Once started I push it in about a 1/4 (on 3/4)and let it warm for a minute, then start out riding slowly about a mile out of my housing development. Then push it to half, and ride for about another 3-5 minutes before pushing it all the way in. The enricher is needed to make sure the engine has the fuel needed until it is warm enough to properly atomize the fuel when more air is added.

Re:starting cold bike 2 Years, 4 Months ago  
Not experienced with an over knowledge of these bikes, but after tuning up my bike i have noticed I needed the full choke to start. Less then 30 seconds but to get it running, half for a minute or two riding then I am good.

An 04 with 14K miles. However in the summer, not so much needed. Usually can start with no choke, but do anyways just to get it to idle right away and not waste on a long idle before riding.

So the guy that know better gave you the answer, mine is just more of a "doing the same thing" post which seems to be the norm.

Re:starting cold bike 2 Years, 4 Months ago  
I have a tach on my bike and you would be surprised at the idle to warm engine range. If you had your bike set up to idle at start up you would be pushing 1200 rpms at running temp engine. Unless you had a fuel injected bike nature of the beast. If you have your engine idle low and ride cold weather the bike won't respond as quick in my opinion. I found my sweet spot at 760 to 780 best performance and milage I believe the factory to be around 900 rpm. Although I'm running a 42 hrs setup . I have to choke my bike all year at any stop over 20 min except when over 90 degrees. When I say that it is less than a half mile and choke is off just what it is.

Re:starting cold bike 2 Years, 4 Months ago  
Mine needs full choke to start when cold. I start pushing it back in after about 30 secs. When warm usually pull choke to 2nd click. I have minimal popping on decel with totally stock setup and it runs pretty well in all conditions. I had the khromewerks mufflers on for awhile and loved the sound but they did increase the popping on decel. Now that I'm back to stock it's minimal again. Biggest change in the bike I noticed was switching to 20-50 oil which really quieted the engine alot. Enjoy the ride.

Hate to highjack but, On my 01 I can pull the choke
full out and it will start closing itself. Is this normal ?
Doesn't sound so from the posts. Sounds like the return spring
or whatever is pulling the knob closed.
Thanks,
Chris

Tighten the nut just behind the knob. But don't get carried away , as the nut can break easily. But you will find that once the nut is tight , it will act as it is supposed to. BB
