2004 KTM 525 MXC Bog

Recommended Posts

So I have searched, read, reread, cleaned, cleaned again, and basically I am at the point that I am ready to take the carb to the mechanic. I figured I would ask the question that seems to have been asked about a hundred times one more time hoping that I might get some help...

Bike: 2004 525 MXC

Problem: Bog immediately off idle

I have:

cleaned the carb

Installed JD jetting kit (including AP pump linkage o-ring and AP pump spacer)

Fuel screw out 1 1/2 turns seems to be about right

Replaced a bunch of other stuff in the carb.

Replaced AP diaphragm

With the carb out I got the AP squirt dialed in. Ended up making a couple small trial and error adjustments to fine tune after it was installed. Dialed in the fuel screw a little more and had the bog nearly gone. It would be what I describe as more of a hesitation than a bog. Before if you had the bike warm, cracked the throttle to 3/4 it would kill the bike. This may be a nice safety feature but not exactly what I am going for.

I have a couple new spark plugs coming this week that I am going to try. I will tune the AP timing a bit more and fuel screw but is there anything else that I am missing? The bike really does run pretty well. In real riding conditions I don't really notice it much as I don't think I go from 0 - 75% throttle frequently but the fact that it does it bothers me.

If your bike is idling and you grab a handful of throttle and it bogs, that is normal. No one rides at idle then nails the throttle. The bigger the engine the more this is true. You can try to better set the AP timing by NORMAL test riding and not just reving the bike in the garage. You can slightly raise the idle speed as many people tend to set it as low as they can and get a consistent idle, where it really should be in the 1800 to 1900 rpm range.

      Anyone else have 130 main and 38 pilot jets already in the carb I took the wifes ttr 230 carb apart to add the bigger jets and this bike from 05 that I bought new already had them in it? I was reading that they came with a 125 main and a 36 pilot.

      Hello all.  Need a helping hand here..  
      I bought an older TT225 and am not about to spend almost $600 on a new carburetor for it. So I'm hoping someone can help me out with an idea of what (other than original carburetor) style, type and brand I should go with..  I'm also having a bit of trouble finding info on this bike.  It's a 1986 Yamaha TT225.  
      Thank you in advanced

      Hey guys, I went on vacation all summer and let my bike sit (2002 CR250). When I got back I ripped it apart and cleaned carburetor and put it back together and it started fine and ran alright, but idled really high. I adjusted the idle screw and realized it was a ridiculous amount of turns out. I can't remember exactly how many but id say 6+ turns out. My killswitch was a POS and didn't work anymore so I replaced it with an oem replacement. My last ride I crashed the bike pretty bad and I was off the bike for 2 weeks. I can't get the bike to start ever since I got installed the new killswitch. I think I wired it right I just replaced one wire at a time and it looked pretty straight forward. I verified it by testing spark while holding it in I was getting no spark but with it in running position it would spark. 
      Anyway I am just looking for some base settings for the Mikuni TMX to get my bike running again, my carburetor has a 35 Pilot and 380 Main jet which appear to be stock. I am located in Edmonton, AB, Canada which is about 2500ft and usually ride between 10-25 celcius.
      Thanks for any replies.

      Hey guys... so I have a problem... I took the bike at Cal City, broke it in, and while I was doing so, the bike was bogging in first gear (Yes, first gear). Also it doesn't idle at all. I have to keep blipping it otherwise it'll stall. So I adjusted the screw circled in image 1. Well I was listening to the sound of the of the bike, yet the rpm's weren't increasing, and it was still stalling. So then, I unscrewed the screw in image 2, well I found out that it was fully twisted to the right. So then, I twisted it to the left, still nothing; it was still stalling... where's the idle screw? I am sure that the screw in image 1 is for the air/fuel mixture screw, and the screw in image 2 is the idle screw, just broken? I don't know, any and every help would be appreciated.

      So Ive decided its time to pull apart my favorite machine and freshen it up, and I'm looking to make some improvements in the process. I already have a 3x3 mod and a JD jet kit done and it seemed to have changed the world. The stock bike just plain sucked and now its a lot better. I never expect 450 race bike power here but I know there is a little more and I'm wondering if the juice is worth the squeeze. I already plan to add a header and exhaust, an FCR39 carb and stage 1 hotcams. After some research it really seems like those places are where the gains actually come from, so would it be worth it to throw a 434 big bore kit at this bike or just stick with what I already mentioned and a new stock bore top end??? Also my rides are often solo and pretty isolated,how much of a reliability headache can I expect with these mods?
