I'll give it a shot tomorrow morning. Also I do get a little backfiring on engine braking so I'm guessing that I'm already slightly lean.

I used this to tune my DRZ to pretty great success https://docs.google.com/spreadsheets/d/1HNSB3DrqJqHTInjVDKKS4HNSHZPbdK0ElbfNI5HxuZg/edit?hl=en#gid=1172546203 (care of Thumpertalk) Check the tabs at the bottom for different carb + exhaust combos

Ended up taking the DRZ to my mechanic today to get my suspension set up. It's amazing how much a few changes effects how the bike feels. Just tightened up the compression and rebound and now it doesn't feel like a noodle. Also it seems like the jetting is fine. The issue seemed to be due to having the idle set incorrectly.

Have any of you guys heard of/tried out the yoshimura MJN carbs? Are they comparable to the FCR39s? e: haha just kidding MSRP of 1199 USD

I was gonna say, I think they're a bit better and a ton more costly. The difference isn't worth the performance gain unless you're seriously racing though. The fcr is a seriously good carb that has performed well in world class racing events. Don't forget that carbed superbike class racing machines often ran fcr carbs back before the days of fuel injection Beve Stuscemi fucked around with this message at 02:42 on Dec 9, 2015 |

Yep. You should look at the jetting table thats on tt and compare to your setup and elevation. Fyi: i bought my fcr used. Dont do that. I spent just as much as a new kit if not more. I need to order a slow jet for mine and or play with the ap squirt duration. Its shooting porn star loads at the engine at wot.

Would the carb make highway riding any more bearable? So, remember that performance mods on the Drz are mostly about not having it fall on its face in the high rpm's. An fcr will help with that, as will a pipe and cams, but you will by definition lose some down low grunt, I'd argue it's worth it, as a properly tuned Drz will pull strongly all the way to the rev limiter, and that's pretty fun, but you'll need to rev it more to make power. In the twisties it will be less about tractoring out of corners and more about momentum now. Which is a good thing, but just know that it changes. The Drz motor really wakes up with an fcr alone, and adding a pipe just adds more of everything. As always, if you do exhaust, skip the slip on only pipes and go for the full system, as the header is where the real performance potential lies. I have no feedback on cams as I've never run non stock cams.

I think I'm gonna pull the trigger on it. I checked out the Thumpertalk jetting doc and couldn't find anything that really matched my setup. https://docs.google.com/spreadsheets/d/1HNSB3DrqJqHTInjVDKKS4HNSHZPbdK0ElbfNI5HxuZg/edit?hl=en&pli=1#gid=1172546203 Im running the yosh rs2 with 3x3 mod and a uni foam filter. 900~ feet. Riding throughout the year so the temp varies a lot but is normally in the 60-90 degree weather. The first one on the list is pretty close but I'm not sure what a NYCR needle type is and it doesn't specify how far out to turn the fuel screw.

While you're at it buy some used E-model cams off Ebay. They're pretty similar to the stage 1 hotcams everyone gets, for half the price. Easy install and a good reason to shim your valves too.

If you ask Thumpertalk 90% of the responses you get are going to be: Pilot: 45 Pilot air jet removed Fuel screw between 1.5 and 3 turns Needle: EMN clip 3 Main: 155-165 The NYCR needle is an OEM Yamaha (iirc) FCR39MX needle. Leaner root and less taper than the commonly recommended EMN. If you do buy an FCR and find a magical jetting setup please post here.

No matter what, you're going to have to play with it and tune it. People in this thread (and on the Internet in general) get frustrated with the thumpertalk jetting recommendations, forgetting that we aren't talking about a little CVT carb off a cb650 cruiser, we're talking about a race carb, built for performance. The fcr is picky, and it will run like poo poo if it's not jetted right, and it can be a bitch to tune precisely because drat near every aspect of it is tunable. But when it's dialed, it is oh so sweet.

What I said is a good starting point. You can also try running the pilot air jet and using a 38 pilot. You're gonna have to fine tune the main jet size. You should probably get some form of leak jet adjustment for the accelerator pump. Get the bike on a dyno and measure the AFR if you want to get it perfect.

The first comment about the airbox involved the post that I quoted about the FCR carb. Right above it. The airbox boot doesn't like to reach the FCR carb. That is the oil filter cover, missing 2 bolts. Dunno, quick cellphone pic. Agreed, but it's all I have since the last 3mm of the OEM bolt broke off in there. The frame has rust there because that's where my boot rubs on this ~22kmi 2005 Suzuki Motorcycle. I think that about covers it. E: It's also really dirty because the past couple weeks have involved alot of dust, then rain. Over and over. Marxalot fucked around with this message at 01:15 on Dec 16, 2015 |

Which is also my plan whenever I have to remove that rusty POS keeping my sprocket cover on e: Worst case is I break the plastic sprocket cover, ebay a new one, and vise grip the rusted bolts off. But they're not really old anyways. e2: I should pull out a Fastenal catalog, measure a bunch of bolts off my bike, put all that in a spreadsheet, and sell boxes of assorted DRZ fasteners to the internet for a 1000% markup e3: Well gently caress me http://www.wheelingcyclesupply.com/shop/product/drc-stainless-steel-m6-cap-boltnut-box-set/669 $100

Not long after I got mine I realized I was losing about 1 fairing bolt per ride. So I pulled the existing ones to see what I needed for replacements. Then I noticed that those had mostly been carefully sawed/ground to the correct lengths. I can kind of understand paying someone else to figure all that out for me. But not $100 jesus
