How many of you have had this problem! I had Dynojet kit installed on my 2k 600 woth Hindle bolt on. I now have a bad bog from 1-3k RPM... Its not as noticable when the engine is cold. But when I have a passenger on the back Ive got to rev it to 6k rpm just to take of properly otherwize the bike just bogs until I get past 3k RPM The mechanic put in bigger pilots still the same problem. I have heard this is common with 99-00 Gsx-r 600. Has anyone worked thru this problem? If so what did you do to solve it!
Frustrated!

Why did you get a jet kit?
You only have a slip on there is not much difference between a slip on and the stock can preformance wise.

I still have my stock jets in my bike.


Sorry man maybe John will know

did you go over your mixture screws/float may have been altered while putting kit in by mistake, or resync carbs. best thing is to get a dyno machine to see what its doing. when you problem happens when it warms up that is a sign of richness.

I have the same problem with my 600. Would anyone suggest the removal of the jet kit. After I installed my bolt on(Two Bros), jet kit and K&N filter I noticed more mid to top end but the low just bogs til about 3500. I was gonna mess with it today to fix but have questions on what I should do.

<font size="2" face="Verdana, Arial">600's do seem to be a bit boggy at low RPM's, thier love is 6k+


Like I said I have a stock jet kit because all I have is a slip on. My bike seems fine at the low RPM's too.

Well have you tried to turn out the air fuel adjuster? Or the float level like said before??? Those two have a LARGE affect on the off idle...

im wondering what kind of mechanic installed your jet kit?? was it a bike dealer??

did the mechanic talk you into this jet kit??

seems to me a jet kit and aftermarket filter is a waste and a lose of power in a stock bike...

this subject pops up now and then, and no one has a fix.....

Check for leaks around the carb boots. I had the same problem it was a carb not sealing. I still have a small bog right off idle. But it is alot better.

I made sure, during the install, that the boots were seated properly. I'm gonna go into her tomorrow. If I can't fix by messing with the floats then out comes the jet kit. Can someone tell me how many turns out on the mixture screw for the stock 600. I probably wrote it down somewhere when I installed the new stuff but can't remember where I put it.
I can adjust from there if needed. Thanks guys!!

<font size="2" face="Verdana, Arial">Most bikes are lean from the factory... So they when you add a slip on it makes that worse... Will the bike run without a jet kit, yes... But when done correct you can get it to run even better.

my bike ran and still is rich from the factory..i had it adjusted leaner by a tunner with a yosh box, but will be going to a dyno soon...

im sure theres room for improvments on any bike, but i read soo many post(here and other sites) where guys are complaining about there jet kits..

the only way i'd mess with one is if a dyno/tunner said i needed one. (actually i rejeted my 74 dt-250 for altitude)

My friend with a 00 had the same prob but it wasnt the jets it was a cracked intake(plastic piece that goes from carb to motor). I would check for leaks somewhere.

If all you did was a slip on and u said that guy went up in needle size then the bike is running really rich. A slip on doesnt make the motor exhale that much easier at all therefore putting bigger needles is just pumping in to much gas that the bike cant burn off so its bogging. Go back down in size and u should be all set.

My guess is either leaks, float height. Everything else in a jet kit is fool proof IE can not really be adjusted. If the bike idles fine likely your mixture screws are good to go.

I have a Kerker race slip on, with KN filter and my bike as sort of crappy bog at 3k also.

I reistalled the original main jets and needles and it runs alot better. Just a hint of a bog down low now. I put the mixture screws at 3 turns out. Everything seems pretty good now.
If I had the right tools and time I would mess with the floats and stuff. Thanks again guys

I had the same problem. I pur they stock jets back in and it runs great. Also, If you have a K&n air filter, take it out. I've been told by plenty of motorcycle mechanics they make your bike run like shit. I also tried it for myself. Adding a K&N filter made it bog down a lot with the stock system and then with my new full yoshi RS3 system with a stage 1 jet kit.

If you re jet a bike... you can always get performance gained. Not in a huge amount without doing a full exhaust or at least a can. I will say from personal experience in tuning and a can that you will see a performance difference. If you get flat spots, check your needle shims and make sure they're adjusted right, and that your air/fuel enrichment is adjusted to the proper level. You should read the manual still and keep good notes on what you're doing with those carbs. Good documentation will help you a lot in tuning so you know where you started from and end up at in the end. Tuning carbs is a bit of work, but I'd do it myself if I were you. You'll realize how easy it really all is, and you'll thank yourself for getting to know your bike that much more intimately. But trust when I say you'll get a lot more power from your bike if you jet it properly and adjust and sync your way to new found power. Maybe also try a +2 degree ignition advancer too. Then go from there if that doesn't suit you. Or! Find someone on Ebay or some other classifieds website that's selling a full Fuel Injection setup from a 98 Gixxer 750. Take the airbox, throttlebodies, etc... Then from that alone, you'll notice once you ride and it's all hooked up right that your power will skyrocket a bit earlier in the powerband range.
