Been riding my F4i for a couple years now and I've got the bug to upgrade. I've been lusting after a CBR1000RR from around 04-07 vintage--Repsol edition. That would be my dream bike. The only thing I've ever ridden close to that was my brother's CBR 929RR, but that was a short ride a long time ago and I was still on my Ninja 250 back then so I had little experience and not much to compare it to. I commute a lot and I also do track days, weekend canyon rides, 2-up trips to the mountains and I want to do some long distance trips soon. I feel the F4i handles all of these tasks really well I'd just like more power a lot of the time. will a 1000rr do as good? Does it feel heavier or less tossable than a 600? I know I need to get out and ride one, but I'd like some initial advice

I'm on the fence about going up to my friend's cottage this weekend on the bike. The weather's looking good for the trip up, (high between 18 and 21C and mostly sunny), but 40% chance of rain on the way back. Also going to be something like 4+ hours each way. And I need map bag/luggage/noise blocking earbuds if I'm going to to it. Bike's running well after the carb servicing, but somehow now the brake lights aren't coming on. I can't remember the last time I checked them. Hmm. And I realized on the way back yesterday that my front light was also out. Turned out to be just a fuse, but yeesh, that's pretty stupid on my part! Chris Knight fucked around with this message at 20:09 on Jun 3, 2009 |

I had such a good ride today. Well, it started off a bit iffy. Sort of a failed reenactment of a WW2 landing. I took the channel tunnel across to France, just to see how easy it was (answer: really freaking easy), and like an idiot forgot to fill up in Calais. I made it to Dunkerque, but I ran out of gas searching for a station. I need a GPS. Thankfully I managed to nurse it to within 3/4 of a kilometer from a gas station and only had to walk it across a mall parking lot. That pretty much ate up what little time I had so I cut my losses and headed back to Blighty. Once back on the other side of the road, I found an absolutely beautiful stretch of road (A28/A262) that was almost deserted and had dinner at a little village pub. But that wasn't the best part. The best part came when I was back on the M25 heading home, thinking about rearsets and I decided to try out my passenger pegs. Oh my god, it's like they were built specifically for that purpose! Feet on passenger pegs, leaned up over the tank, it's like I found another gear! 85-90mph was actually comfortable and easily maintained! Previously I never really cruised much above 75 because of the wind and vibrations. Downside is boy howdy do you ever burn through gas at that speed!

I want one too, but not a Repsol. Just the red one. It will actually be less comfortable than your F4i (OH GOD THE SEAT), and feel even smaller. And have a comparably retarded amount of power. Do you have a banana seat F4i or not?

Phat_Albert posted:Carbs are the poo poo son Carbs are frustrating sometimes because there is this big area between "runs" and "runs awesome" that is completely dependent on cleanliness, jetting, exhaust, intake, and numerous other variables. Depending on the bike "runs awesome" can take forever to get right. My YDS3 ran great, or so I thought, until I decided to try to fix the hard starting problems with some new pilot jets. Now it runs like a raped ape. Similarly new exhaust gaskets magically added a million horsepower as well.

Depending on the bike "runs awesome" can take forever to get right. Carbs are the poo poo because you can tune your fueling extremely close without a dyno, sniffer and powercommander. To be truthful, you still need a dyno and sniffer to get carbs really really dialed in, but buying new jets and needle shims for  is way better than shelling out for a PCIII.Although to be fair loading a powercommander map over a USB cable is infinitely easier than pulling a rack of carbs and futzing with jets. Futzing with jets and fueling is half the fun for me though so carbs are the poo poo.

I just prefer the "works right in the first place" kind of fuel delivery system. I should never have to worry whether the engine is getting the right amount of gas. If the bike starts running badly, it should be a sensor fault, not something actually wrong with the fueling system.

Oh poo poo, I started a debate!  Weather's nice, I'm in a better mood. I tried to sync my carbs yesterday, and now it starts/idles worse than ever. Gauge needles on 2 & 3 were fluttering like crazy, 1 & 4 were rock steady. I removed the vacuum fuel shutoff (there's a manual petcock), but my >5k RPM misfire is still there. Might be a bad coil or ignitor, I dunno.

The first time I had to pull a carb only to have a small spring go flying across the garage never to be seen again would completely justify the the 200$ for a PCIII USB plus the 45$ for 3 dyno pulls to tune it out. Change the exhaust? Less than 10 minutes with my laptop plugged in and I'm good to go. No rejetting or any other of that horse poo poo.

By "removed" do you mean blocked the hole in the manifold or on the carb? Otherwise you have a barn door vacuum leak. If the gauges are fluttering it probably doesn't point towards ignition, as intake air will be operating normally even if the cylinders are just along for the ride. It could of course also be too little restriction in the hoses to the gauges, as intake pressure is supposed to flutter. Valve clearances and vacuum leaks = the big deals. Problems upstream of the carb can also manifest themselves in intake problems. Rule of thumb, make sure everything is stock and tight.

^^ Dude, there's a point where it just doesn't matter anymore. Four Keihin VB's or Six? It's like "Do I want nine children or twelve?" There's no difference after three that you'd notice.Bucephalus posted:I hate carburetors. You are now me one year ago. They're not as bad as you're making them; take them one at a time, clean them as such, make sure the accelerator pump is working properly and clean those little holes too. The worst part is getting them into and off the bike. OFF: Use Tie-downs. ON: Use Tie downs. Also, they will pop into the intakes and they WILL be straight on. Do not second guess this or you will have air leaks.

I meant to reply to this, as I've ridden a couple of CBR1000 generations and owned a 929. A 1000RR may or may not be as comfortable as your F4i. That's a personal thing that you have to figure out. It doesn't feel a lot heavier or less tossable, and it's got an awesome spread of power all through the rev range. It's probably going to be less comfortable than a 600 for 2 up and stuff. It'd feel like massive amounts of overkill at any of the smaller tracks, my 929 at Streets was decently quick but an exercise in frustration when it came to maintaining and dealing with corner speed and corner exit. I felt like such a newb, all straight speed and no corner speed. They're really, really good bikes. Excellent first literbikes, as they've got an awesome progressive spread of massive amounts of power. I know of quite a few people who daily theirs, I've just gotten lazy and tired of being bent over a sportbike. I loved my 929, my biggest problem with it was that I just couldn't stop going fast. Picked up a few tickets and realized that doing 130 regularly up the twisties was going to get me killed. It was such a fantastic ride though...I do miss it.

It could of course also be too little restriction in the hoses to the gauges, as intake pressure is supposed to flutter. The vacuum port on carb #2 had a nipple in it to operate the shutoff. After syncing, I inserted a spare blockoff screw. I tried to quell the fluttering on gauges 2 & 3 by pinching the hoses with pliers, but to no avail; they didn't calm down until I had closed them off completely. (I also swapped gauges 2/3 with 1/4; it's the cylinders, not the gauges.) After 22k miles with unknown maintenance, the intake valves may be in less-than-ideal condition. As for the high-speed misfire: does anyone know of an elegant way to test for ignition under load? Shlomo Palestein posted:carb tips Had them off 4? times, they're clean enough to eat from.

Man, my local place has a 2007 Triumph Daytona 675 for $4500.. that sounds exceptionally low (and no pics are currently available yet). I've also heard they're horrendously uncomfortable, can anyone confirm/deny? Making matters worse, they have a DRZ400-S (offroad trim) which I'm considering trading my KLR for.. Ahh well, neither of those will probably happen, but I may go up and look at the Daytona, because they're so sexy.

From what I've heard the Daytona is a little better than the rest of them if you want to ride it daily, due to the triple engine instead of the I4. If I remember right, it's got more torque at low end, so it's easier to ride on the roads. But you're mostly right, it is still a 600 supersport.

Huh, interesting, maybe I'll go up and have a seat on it today, I thought I'd heard (perhaps read -- maybe in the 600SS review on a motorcycle review site) that the 675 was down with the GSXR on comfort. *shrug* I guess ultimately it comes down to personal preference anyways. Seat height shouldn't be a problem, as I'm both 6'3" and a spring-compressing 250lbs. I'm not interested if it's a salvage title though, they're pretty rare over here, but I can wait for the next one.

Everything I'd read about it was along the lines of "remove restriction, gain a couple HP", not "ZOMG it's like running with the choke closed!". Last night I happened across an old SOHC/4 thread wherein the dude was seeing the same symptoms I was, and basically rebuilt his entire fuel & ignition systems to no avail. He finally removed the airbox cover, and presto. I don't know how the drat things even ran when they left the factory. It's not perfect, there's still sputtering/throttle twitchiness around 5500-7500, but I rarely see the other side of 5k, so I'll cope.

You should. I always tried to keep mine around 3-5k, but the i4 really likes higher revs. Beat on her a bit and she'll love you for it  I sometimes have that same problem where I'll lose power around 6k when on the freeway (if that won't make you poo poo your pants very little will). Hasn't happened recently but be sure to clean out the vent hole in the gas cap.
