Rejetting a stock bike

[sveach]

I currently have an open exhaust and air pod filters. It's rejetted right now, I don't remember what to...I know my mains are 150s. no idea on pilot/mid main.

I'm going back to stock this winter. I'm tired of the loud exhaust, and when I ride in HEAVY thunderstorms, the bike sucks in too much water and bogs down too easily. I could fab up a splash shield or something but I'd rather just put the stock airbox back on. I have everything I need to return to stock, including the jets.

Should I rejet it to run a little richer from stock, or just take it back to stock completely? I know that our bikes run a little lean from the factory.

I am for sure, going back to the stock exhaust. I would consider the splash shield idea for the air pod filters if it's actually WORTH it to keep the pods. Thoughts?

my lunchbox filter (just a big pod filter) doesn't suck up any water even when its raining sideways. 
does your bike have the old 2 circuit carbs, or new 3 circuit?

[sveach]

Mine's a 2007. So 3 circuit carbs.

It's only done it to me once. Last week, The roads were flooded and the water was about 6 to 8 inches deep. The rain was still coming down HARD as well. Visibility was something like 100 feet in front of me at most.  I didn't have any high ground to get to so I just kept going through it until I got to a dry spot. It was kinda fun...I was standing up on the pegs riding it like a dirtbike...

After that, I couldn't rev it up past 5k without it bogging down. 30 minutes later after sitting in lots of traffic not moving (so, idling) (rain had slowed to just a little sprinkle) the bike was fine. So my assumption is that it was just pulling in too much water through the air intake.

It's been fine ever since, and it's the first time it's happened.

Thoughts?

I like Campbell's chicken soup.  Gotta be the Homestyle kind with the little noodles, though. 

I'm more of a beef soup, maybe chicken and dumplings kinda guy. Gotta have some substance to it!

I just rejetted my bike from stock. Pilot 17.5 mid 60 and main 130. Ole boy runs like a top!

Bike never shut off...just bogged down a lot. Ill drain the oil and check it as soon as I get a chance.

Why the hate for the stock air box? It's been awhile since I've used mine but I don't remember it being THAT much of a pain in the ass...


Toogoofy...thanks for the info - I'll keep it in mind if I do go back to stock completely.

I'd like to know what's wrong with running the GS stone stock, from the factory the bike runs great, sounds fine, and gets the optimum gas milage--fooling with jets, air boxes, pipes, and gearing is a total pain in the ass and yields next to nothing in benefits. I went through all that crap for years and finally learned my lesson---think about it, what have you really and truly derived out of all that hassle, headache, and expense?

[pandymai]

with that much water, i would imagine it more likely that water was sucked into through the exhaust. the backpressure every time you left off the gas would create a vacuum pulling water in..

just as advice (if you dont know already) always keep a steady throttle to keep exhaust pushing out of the pipe, and feather the clutch through the flood areas. if you dont, again, the water gets sucked in.  i havent had to deal with that before, but good luck.

Mine is stock, too, I feel same way, mostly. But since I am in USA it makes sense to do buddha's jet kit to remove intentional lean condition mandated by you know who- the US government.

Its now runs better than new and gets same mileage.

I actually like the fact that I don't have to sit and let my bike warm up for five minutes in Florida during August. Before I'd let it warm up for five minutes and still die at the first two stop signs in the sub-division. Now it is pretty much turn the bike on put on my helmet and go. No dying!

It took me and my friend less than an hour to do and I've been more than happy with the upgrade. PITA not really if you go on the Wiki. The last two tanks I've gone to reserve at about the same milage. And adding it was a b-day present from the Buddha last year was nothing outta my pocket! :bowdow

As good as it runs now not sure if I'm gonna go buy the K&N and exhaust or if I do it will be when I have the expendable cash!

It's running richer, I doubt it gets the same milage, but probably not enough to really matter. I never had a warm up problem with any of my bikes once they got broken in, not even in the colder weather, but I guess I would give it shot if I had to go through your 5 minute ordeal every time I wanted to ride.

If you don't like the bike as is move up a class. But do us all a favor and learn how to ride it first!

[ojstinson]

Jb848 that doesn't make any sense to me, I do like the bike as it is, isn't that the jist of my comment. And I do know how to ride, I should, I've been riding since 1972.

[JB848]

So the jest of your comment was the bike bogs down? So when I bought my 2004 GS500F I rode it home 120+ miles in a monsoon. Granted I do not do it everyday but I had no problems other then once at a stop light it popped. I have ridden my GS500E for 9+ years in NC an TN in the heaviest rain. I think your issue is coming from the proper air cleaner?

Also just because you have ridden for so long never means you can ride it or maintain it properly. I have been riding just as long if not longer as you.

Scroll up and look again at what you commented on, I think that post of yours was meant for the OP, not me.

I was agreeing with you against the poster silly and used you as an example...Sorry!

Ok, that's cool.

I was giving it constant throttle while I was sitting in the rain like that...since it was bogging down when I let off the gas, I stayed on it, as I didn't want it to die. Not sure if it was going to or not, but I didn't feel like finding out.


JB848 - You're confusing the hell out of me, lol.

Are you saying I need to learn to ride, or was that comment directed specifically at someone else? I'm not a new rider by any means either...

Re: airbox - I think I will try to go the route of splash shield. Why change from stock? I like to tinker! Working on my bike is almost as much fun as riding it. Performance, eh. This bike isn't going to be a speed rocket no matter what. It's just fun to play with. I'm not doing it to make it any faster.

Over the winter I'll be adding a 17 tooth sprocket AND im going to a 130/90/17 tire. That should lower the RPMs quite a bit and allow me to get much better gas mileage. Reliability is my biggest goal. Changing the stock airbox may be detrimental to that, I know...
