  1. The o-ring that goes bad and floods gas into the engine is the float needle seat o-ring. O-ring is 1.5mmx7.5mm You can find them on amazon here. The stock mikuni o-rings are actually a slightly different size (7.75 I.D. x 1.53mm), but the amazon ones work just fine.

  3. I just went through this with mine. The float needle seat o-ring failed, and dumped fuel into the carb, which went into the intake and then past the rings and filled the entire motor with gas. I drained almost an entire jerry can of oil/gas mix out of the motor... That o-ring is not sold individually, you will need to either buy the whole assembly (I was quoted $75), or find a generic o-ring of the correct size and material. I would take jjktmrider up on his offer, or since I just had to buy a bag of 50 of them, I could also send you one.
  4. Yeah that is not "air suspension", do not remove the nitrogen. You can not change the height of the bike that way. That screw on the carb (the metal one, not the plastic one) is the float bowl drain screw. If you loosen it, the gas will drain from the bowl. Maybe it just needs to be snugged up, and that is why it was dripping. If not, remove it (put something under to catch the gas that will come out) and inspect if it has been marred from being over tightened, it is a metal to metal seal. Hard to say what the residue (gunk) on the carb is. I'd clean it off and keep an eye on it and see if there is any leaks. Possibly the bowl o-ring has a leak and thats gas and dirt collecting.
  5. I just replaced mine, along with the float needle seat o-ring (check yours if you haven't, it can lead to your motor filling with gas if it goes bad). It is a circular cross section, I ordered the direct OEM part.
  6. Any reason you'd recommenced them over the mt21's? Also I read the 606 is a favourite, however it is a little more expensive. How do you find it wears? What kind of life do you get out of yours? How is it in the wet stuff? That is the only thing I'm slightly concerned with the Pirellis about, that they wear extremely fast on the road. Have you used the MT21? How does it compare to the Trakmasters? My friend is getting Trakmasters for his DR200, I was thinking I'd get a different tire and we could compare. The Trakmaster is about 25% cheaper though... Do you run them front and rear?
  7. --Update-- Got the parts in a couple weeks ago (just getting around to typing up the update). Quickly installed the new seals into the carb. The non mikuni O-ring fit perfectly on the needle seat and (so far) has been sealing perfectly. The old air cut off diaphragm was wrecked, I didn't realize how bad it was until I had a new one to compare it to. Is this just from age? Bad gas? Or (I'm thinking) someone previously sprayed a bunch of carb cleaner in this carb and it wrecked the diaphragm. You can't tell from the pic, but the old one is hard and bubbled. Unfortunately I should have bought a new bowl cover (?) seal/o-ring, as once I got the carb back on and filled with gas, it slowly wept out through the seal... However, aside from that one last seal, the carb is spotless now, and has all new seals and ready to roll. I even redid the small hose holder/guide with new heat shrink as the old rubber was ripped and looking ratty. As to of getting the carb back in, what a chore... getting it out is much easier, and faster. Not looking forward to doing that again when I replace that other seal. I put new oil in the bike, hooked everything back up, held my breath and pushed the starter... fired up instantly! Unfortunately it was 10pm and snowing out, but that couldn't stop my excitement, so I took it out for a bit of a ride. What a blast haha, was sliding all over the place, but it was fun. Everything seems to run well, although I'll need a full and proper ride to make sure, might be a slight hang in the rpm when you rev it. Next step: Wait for warm weather so I can do a coolant flush, and repack the linkage bearings, there are a few loose spokes as well. So when I get the new tires I'll give the wheels a thorough go over. Need to buy tires, levers and new foot pegs. These stock pegs are atrocious... but it turns out new foot pegs are kind of expensive, who knew... I'm thinking of going with Pirelli MT21's front and rear. I'd rather have the best grip off road as I can get, and where I live the next few months ( probably until June even) the trails will be fairly wet and muddy (some trails are muddy all summer depending how much rain we get). So I'm thinking the MT21's will be a good choice, as they are fairly aggressive knobbies. Any thoughts on tire choice?
  8. Might want to open it up and check what kind of connector the antenna used to attach to the PCB (soldered, smd coax etc.). If it is just a small length of wire (the length will depend on the freq of the transmitter, bluetooth being 3cm), you could probably just resolder an appropriately sized length of wire. If it is a coax lead to the antenna, then you might be able to purchase a new on from a RC hobby site for cheap. Anyways, I would open it up and have a look, then you can decide what to do.
  9. Just going through this with my bike now (here), Erik was super helpful in sorting it all out. I currently have 50 of the needle seat O-rings on route (smallest amount I could buy on amazon at the time). So I will have lots of spares if you need one.
  10. Makes sense. However, the bike was off, on its kickstand, I was just looking it over. I noticed the build up of gunk on the shifter (seen in the pics) so I grabbed the shift lever, and wiggled it around a bit (up and down, forward and back) and immediately a drip of gas/oil came on. I wiggled it a bit more and a steady leak came out of it. Once I let go, a second later the drip seemed to stop. I'm sure the gas thinning the oil, as well as the massive amount of gas in the motor at that point had a lot to do with it, however if it leaked that much I'd assume it needs replacement. I ordered the o-ring for the float needle seat. Of course amazon.ca didn't have the 10 pack in stock, so I had to buy the pack of 50 for $14 instead... if anyone needs an O-ring, let me know, I'll have lots now! Then I ordered a new diaphragm, other o-ring for the carb, oil filter o-ring and the shifter shaft seal from partzilla (thanks for the link and recommendation to use the cheaper kawi parts!). Waiting game now until the parts get delivered, then hopefully I can get the bike started! Will keep the thread up to date. Thanks for all the help everyone.
  11. I would agree, except I saw oil pour, well not pour, but substantially drip (I think due to the thinning from the gas) out of and around the shifter shaft when I moved it with my hand. Leads me to believe it needs the seal. I will clean it up of course and ride it and see, but I think I'll add the seal to my part order (it's only $4.50) at the same time I'm ordering the parts for the carb.
  12. Float needle seat O-ring. Thank you so much for the link! I had been trying to figure out how I was going to get that damn O-ring. That is perfect. I checked the link you had given me before Erik, and while the package was only 5 bucks, it was like $15 shipping, plus that was USD... so in the end the stupid thing would cost me $30 CDN... That amazon link is perfect. Now I just need the diaphragm and the other O-ring and I'm set to get the carb back on the bike. The compression tester I bought arrived today, so when I got home from work I hooked it up and nervously tested it. Happy days! Looks like the compression is good! Once that was discovered, much to my relief, I put the valve cover back on, new spark plug in, and new oil. I pulled the drain line mesh screen to inspect it before I added the oil... It was pretty clean. I washed it, and reinstalled it. I had noticed when I first got the bike home, that oil (later determined to be oil/gas mix) was leaking from the shifter shaft. So I think it needs a new shifter shaft seal. Should the shifter shaft move in and out slightly from the case? It probably only moves about 1mm axially, could this indicate a worn item, or is that normal slop? While I had the sprocket cover off, I took a look at the sprocket, as I had read these seals can also go, and there is a fix that should be done to them. I couldn't see behind it so hard to tell if it was leaking as well, but I don't think it is. It looks like this sprocket might be on its last legs as well, thoughts? At this point, my next action is to get the carb parts I need, get that back in the bike, and fire it up and ride it for a bit to make sure everything is good. If that checks out then I will be moving on to taking apart the linkage bearings, greasing them, coolant flush and replacement with engine ice, brake bleeds, overall clean and inspection, new tires, new levers, and whatever else I discover I need along the way. Thank you guys so much for you help so far! I'll keep updating this thread as I go.
  13. Well that's a whole lot better. I called the Suzuki dealer, gave them the part numbers, and those are the prices they gave me. Keep in mind I'm in Canada and everything costs more here. But the price difference between what you got, and what I got is crazy. I see you went with the Kawi parts, I read they are the same but cheaper, guess that's true. Where did you find those prices? I just wanted to see how much it would be, since you can't buy the o-ring on its own, I got the lady to give me the price of the whole assembly. I don't think I need to replace the float, but that is the only way to get the o-ring from the dealer. Obviously I'm not buying that, the price is ridiculous.
  14. Thanks. Yeah I had that part number, called Suzuki, and its a $6 plus tax O-ring... so I was hoping if I had the size I could just find an equivalent one for like 50 cents. But that is way too much work for you, just to save me a buck, and you've already helped enough. I'll just buy the Suzuki one. I also asked if they could get me the float needle O-ring, no go (of course). I need the air valve cutoff diaphragm as well, so got them to quote me on that. $130 plus tax for the o-ring, float assembly, and diaphragm... lol what a joke. I just need a couple o-rings and a piece of rubber.
  15. The bikes already have a custom made area where they are hung from the wall, can't move them, plus the ceiling isn't high enough and there is the garage door which takes up the whole ceiling space when open. Thats a pretty expensive fix vs a couple dollars in O-rings haha... Thanks again Erik. It seems I misunderstood due to the naming of the parts. While i do need that O-ring, I also need O-ring#13 here. The calipers say it would be about 5.5mm I.D. but I need to know the O.D. as well, and I assume they are sized slightly larger/smaller to account for compression. Do you know the spec of that O-ring? Also, still waiting on the compression tester, hopefully it arrives soon, I'm anxious haha.
