I did the breather re-rout, what a difference! The bike would not accept blips of throttle from idle before doing it, and I found my air filter to be quite drenched in oil. Did the mod and it just runs much smoother than before. I did it "my way", I wanted the filter to be away from the rest of the setup with the pipe connecting to it being straight up so nothing could come into it. Seems to work fine. After a good ride this Sunday I will eventually put black zipties, the white ones just look ugly. http://img651.imageshack.us/g/img0243j.jpg/ | ||

Did you do anything with the airbox (drill holes, open air box kit) or just the breather mod? I have a bone stock '06, I just drilled thirteen 1-1/2" holes in the airbox last night and it made a nice improvement. I'm curious to see if the breather mod makes much difference over and above just opening up the air box. I did both mods at once on my last XB and really liked the change but I'm not sure how much of that was attributed to the breather mod alone. | ||

Untrain your right hand so that it doesn't blip the throttle. Your intake is so big that there is no real need to do anything more with the throttle than open it up when the time to move forward comes. All of your previous bikes likely had either very small carburetor bores or multiple small throttle bodies for their F.I. (when compared to the Buell) and so blipping had its own purpose or reward. Not so with your new love. Make your Buell happy and treat it differently than you have others in the past. Resist the blip.  | ||

I heard it doesn't like it, why is that? I blip the throttle only when downshifting, is that also to be forgotten? | ||

The explanation I've been given is; With fuel injection the ecm is not programmed to understand what is going on when you blip the throttle. It is only thinking logically. What is the logic in blipping it? If you are raising the RPMs on a down shift, just raise them to match where the engine needs to be for the lower gear. That is logical.  | ||
| Leoallafila |
That does not make any sense form a mechanical point of view, is it maybe related to the crank-pin upgrade they did on the later models? | ||

Let me clarify first: matching engine RPM with speed for downshifts wasn't what I was warning against. The warning has to do with a big dose of air being dumped in to the intake on the blip. The mix gets all screwy and the ECM, not being the predictive type, is attempting to respond to the woosh of air that gets sucked through when that baseball sized butterfly flaps open. I only ever seem to foul plugs when I blip so I stopped. YMMV and all those other caveats. I've had no issues with matching RPMs on downshifts and learned to do so more smoothly now because of this bike. Before, on previous bikes, I could just snap open the Mikuni, Keihin or Amal for a split second and then find that gear (or enjoy the sound of the blip note). Hope that clarifies it some. | ||

That makes more sense, so the "bad" result of blipping the throttle is fouling the plugs? doesn't sound that horrible to me, but I appreciate the heads up. | ||

I've preached the No-Blipping mantra many times here for the ULY. It is not carbureted. I used to be a freaking stop light blipper until the rear plug fouled at about 5k miles and haven't had a fouling since in over 25,000 miles. | ||

Have 200 mi on'er after the re-route and the engine seems much smoother now, I think the ECM has re-learned the map since it always gets fresh air. Idles evenly without the occasional miss that it had before. I was out for a ride yesterday and kept trying to up-shift as it seemed to have 4th gear pull but was already in 5th! At this point I'm wondering what improvement an Erik Buell Racing ECM would do for me? | ||

I never understood the need to blip throttles at all. If the engine is running right, there is no need for it, carbed or FI. Maybe there isn't a, "logical" reason for it. | ||
| Leoallafila |
there is a definite need to blip the throttle when down shifting, the rest is just fun | ||

When I'm in my truck or car at a light and a H-D rider inevitably blips their throttle like a nervous tick, I'll do so too just to rain on their parade.  | ||

Throttle "blipping" was common on old 2-strokes, they didn't always idle well and would occasionally die at long stop lights (and then need a kick-start) unless you bumped the gas once and a while. | ||

My first bike was an RD400. I wish I still had that bike and I'm reaaaalllly sorry that I sold it for the foolish young man reasons that I did, (bigger bikes). Bone stock and in beautiful shape. It ran well and would idle without problem. Those old two-strokes were fine in tune, but a little out of tune, and/or modified and then all bets were off. As for others doing it a lights, it's just some kind of a thing with them. I hope to see some 2-strokes at the Riding Into History Motorcycle Concours later this month in St Auggy. Any of you going? http://www.ridingintohistory.org/event | ||

Busykat, I was pondering going up (I live in Deland) as I have a 1957 BMW R60 /2 I'd like to let someone else take home with them for the right price. | ||

I blipped my throttle at stops on my BSA 441 Victor. It seems if you let it idle it would be fine but as soon as the light turned green you would go to take off and it would die.  There you are, light green and you're trying to kick that bastard to life again!! I drop kicked the Amal carb and replaced with a Mikuni. No more problems and no more blipping! | ||
