So hi y'all! over the last few weeks i've picked up the $650 to get my 05 gs500f all fixed up. it had a completely clogged pilot jet, some crud in both carbs, and a nack for somehow idling on one cylinder :thumb:
also, had the front wheel replaced, as it was slightly bent. (the p.o. wasnt any kinder to his first bike than i was)
Now, after a rejet and a replacement of the stock filter to a k&n drop-in filter, i've noticed quite a few problems. firstly, and its hard to see without tearing the bike apart, it seems the right carb isnt mounted on the manifold properly. and often, ill feel a burst of air an hear a pop from the right side, and a lull in the engine. (sometimes it just dies at speed...)
the second problem, is that even when the bike seemed fine, if i twisted the throttle just a small amount too far, say trying to accelerate past 7k rpm, the engine would stutter and bog down. is it possible for a mechanic to mix up the mid and high jets in these carbs????
a bit more info on the jets. i've always read that the bikes come from the factory slightly lean, so i chose to upgrade the jets, and also asked that a k&n lunchbox airfilter be put on the bike. (seems they forgot that part, as the airbox is clearly still on the bike...) At low rpm, when the carb boot isnt killing the bike, the bike responds really well. first time its really ever had any get up an go around 3-3500rpm
any and all advice would be appreciated :)
EDIT: Another problem i've just remembered, is that the bike is increasingly difficult to start in the cold, temps anywhere from 30-50f. a 10-mile round trip the other night killed the bike around a dozen times, and even though it was warm, i had to apply choke and let it crank for 1 minute plus to get started.
If your bike is dieing at speed I think it is worth tearing your bike apart if you think the carb is not mounted properly. The bogging under heavy throttle could be too much fuel. DO you still have the stock exhaust? What do the plugs look like?

Plugs are not white, more of a tan color. Exhaust is totally stock, only things really changed were the jetting and a k&n drop-in filter.
to elaborate on the throttle issue. it seems that the bike hardly wants to get up to 7000 rpm even when babying the throttle, but it still accelerates better if you creep up than if you tear into it at all. sorry if that doesnt make sense :cool:
so the bike was not doing this before you got the rejet?
i'll be following this thread closely as i'm having very similar problems with my 06 parts bike..
Nope, only problems before were an air filter that looked shaZam!, a clogged jet, and a bent front rim. the issues im asking about now came just after the rejet.
Bit of an explanation lol :cookoo:

im guessing embedding isnt gonna happen?
hmmm 05's seem to have a lot of problems... lol
EDIT: it actually sounds like there is something wrong with your engine, have you checked your valves? Mine was sorta doing the same thing not nearly as bad tho. These engines should be able to be Rev'd to ALL FREAKING HELL! all freakin day too. So when something like this happens its not "normal" its not a kawasaki :D
valve prob huh? i guess it would need checking out, as the bike has 11000 miles...

mine has 17. Seems like 10-20k miles they need a checking.. even tho they should be checked more often. what's good about having a single bike. is you can collect new/used parts for it. and use them later. As I'm never gonna sell my GS, so the new an used parts will come in handy later when you need them..
That carb MUST be all the way into the boot.
Don't have a manual in front of me but I believe it is every 4k miles for a valve check. I bought my '01 with a bunt valve at about 10,000 miles so definitely something you should keep on top of.

i guess i'll be getting very intimate with my bike, if the valves need checking lol. time to look for tutorials hehe. also, the carb fits how far into the boot?? i thought it was just around the lip of the boot.
i agree with paulcet that carb needs to be pushed all the way home and tighten the clip that keeps it from leaking more air in, also check the other hose clips are all tight.

Screw being nice to your carbs.. Rubber mallet and smash those babys in! thats what I do, nothings ever broken, but please.. do use a rubber mallet....
Haha, had no idea that it was standard procedure to bring a mallet along :P

Well.. They can be tricky to get all the way in sometimes. My boots aren't terrible. but they are a little "Dry rotted" if you know what I mean...
but yeah just smack them in with a mallet. simple as that, if you still have air leaks your boots are bad.. there are ways around this. including some: ducktape. super glue. Epoxy. rubber glue. cotton balls. playdoh. squirrel pelt. Lol JK don't use any of those. Just get new ones..
