Poor Mans Stage 1 kit

[rider123]

Does it look like a "doughnut"? I'm eating dinner but I'll get you a pic in 30 mins.

[deanozx10r]

Ya little white donut!!

[rider123]

Yeah thats the spacer don't remove it. Are there any shims under the doughnut?

[deanozx10r]

No, I got the ones from radio shack. There all different sizes but I think there same thicknesses.

[rider123]

Yeah they work fine. The radio shack shims are equivilent to 2 Holeshot. So 2 Radio shack shims on there will do for a stage 1. If it doesn't have any shims under there thats probably your problem. Try a couple of shims and see if that helps you out before going to the trouble with installing new jets.

[deanozx10r]

Alright lets start over my eyes(slap me!!) There was 5 little spacers on the needles, I didnt see them after pulling out the needle whom ever put them in should have put them under the donut. They came out when I flipped the slide upside down. So now I thought I'll check the mixture screws they had them at 4 turns out with the 17.5 pilots in. If I leave in he spacers and back the mixtures screws out to 2.5 turns you think that will do it? Or should I just go get the 112.5s?

[deanozx10r]

But if I go 2.5 turns out then it'll be leaner right, ya I think thats the way it works. I think im going to need the bigger jets. Thanks for all the help Rider!!!

[rider123]

No you got it right. 2.5 turns on the 17.5's is the equivilent of 4 turns on 15's at idle. However the 17.5's will still be slightly richer at cruise than 15's. You may actually be totally fine with the 110's in there. I needed 112.5's but you may be fine. Keep in mind it's winter as well so a little leaness is expected. What I would do to make it easier on yourself. Is get it running as good as you can with what you have in there then do a check of where you need to go. A rich mixture will cause hesitation as much as a lean one. Just make sure you have all the same number of shims. If you have 5 little shims on there chances are there is a holeshot in there, keep the 5 shims and adjust the mixture screws so it's driving well then maybe check the plugs and see what they are saying to you.

For example when I had your setup. I could wheelie like crazy at 2.25 turns but at 2.75 turns it ran like a dog because there was too much fuel down low. Now when I had it at 2.25 turns out it would drive a little wonky as it was fine up to about 6-7000 rpm then got weak with the small mainjet. The fueling was off where I was compensating with an overrich pilot with the screws and having a lean mainjet. However that is my bike, your bike may be totally fine with 17.5's. I would start out at 2.5 which is close to the recommended settings from Holeshot and see how it goes from there. Drive at least 20 minutes before adjusting anything so you know your fully warmed up.

I'm basically the same overall fueling as you however I moved the extra 2.5cc/min of fuel up top where it was needed on my bike. Cruise and down low was waaaay too rich on my bike with the 17.5's so I reduced the pilot and upped the mainjets. We have basically the same fuel going in there but I'm putting it where it's most needed up top. I'm at 4 turns out right now but I think it's a little much but it's like 40F degrees max when I go out to test it. Probably when it's warmer it should be around 3.75 or so. I can tell its a little lean at this temp which is a good thing as if it was perfect at this temp it would be horridly rich at summer temps.

I will try it after I go through and clean everything. Maybe its a pinched line or something, Im going to put all new on as long as I got it all tore apart.

The reason I think the main is to small is that its fine when Im just tooling around, but when I pick up the pace and use full throttle it dose this. But its funny It'll be fine for awhile then slowly start to hesitate off and on full throttle then the more I use it the worst it gets. Now im starting to think its a bad gas line, it was soft and mushy. I dont know!!!!!!!!!!! Im pulling my hair out what I have left LOL

[rider123]

Well put it this way if you dumping alot of fuel in there at cruise with rich pilots, dumping more and more fuel with more and more throttle is going to make it worse and worse. If you were at 4 turns out on 17.5's(holy phuck batman!) thats the equivilent of 5 and 1/2 turns out on 15's!!!! turn those puppies in to 2.5 and work from there but only after you've run at least 20 minutes minimum. I would wager if you pull your plugs they're sooty as hell. Maybe pull one to confirm.

[deanozx10r]

Ok I will do that!!! I'll let you know what I find out

[rider123]

If you have the time and enough jackets go for a semi-long highway ride to clear out all the coking at having those pilots so rich. Even just 20 minutes on the highway will really help you out. Maybe some fresh gas couldn't hurt either if you can top up the tank with some fresh stuff. Since it drives worse and worse as it heats up I'd be dollars to doughnuts it crazily rich.

Well I still got the carbs on the bench now and its supposed to snow 3 days this week so next week. Im getting excited and sounds like you know your shit!!! I love the bike but wish I would have gotton the 1250 with EFI!!

I love the bike but wish I would have gotton the 1250 with EFI!!

You won't say that after a valve adjust, or coolant change, or oil change.    (  to the 1250 guyz) 

[rider123]

Hey while it's on the bench make sure the float heights are set to 13mm. Mine were all over hell's half acre from the factory. Also make sure the emulsion tubes and jets are nice and snug. Be careful they are soft brass so don't go jihad tightening them in there. nice and snug is fine. You can set your mixture screws easily to 2.5 turns to start.

Also EFI has it's own gremlins as well. Number 1 being you can't rejet it with $12 in jets. But it does a better job when you buy a power commander or EFI override module. But they are pricey. Once the carbs are set up nicely, they will work just fine and generally won't have to be touched again, but if you wanted faster warmups in the winter you could turn the mixture screws a 1/4 turn out under 50F, turn them back in a 1/4 over 50F once you have them set properly. Ie if you're good at 2.5 when it gets cold maybe turn them to 2.75 when it's super cold it will help warmups and running, but if you're uncomfortable with that or forgetful you can just leave them where you are good but just remember the bike will take a little while longer to come up to steam and may be slightly lean in winter.

Sync the carbs up using this method and your good:
