Question about 2007 Buell Lightning Long XB12Ss

1 Answer

Surge at low rpm

Just picked up my new long lightning. I've put 300 miles on it and it runs great at 3000 rpm and above. Around town at 200-2800 rpm it surges and just doesn't seem smooth. I took it back to the dealership and they said its fine. Is it the nature of the beast or is something wrong?

Is it brand new? If so it's pretty normal. The bikes don't like running smoothly below 2k at all. As it breaks in it will get a bit better but it's difficult to not jerk it around at low RPM and slow speeds. Best bet is to keep the RPM at 2200+. Also if it is new when you get to the 1k TPS reset it should help as well.,,,

2000 Buell Blast runs great around town. Freeway speeds runs for 3 to 5 miles then out of nowhere dies. Acts like it's running out of fuel then dies. I have pulled the carb and cleaned the jets. C


If it starts up after sitting for a few minutes, (like 2 or 3) it could have a plugged fuel filter or the gas tank strainer built into the fuel valve could be plugged too. Drain the gastank anyway and change the gas with fresh. can't hurt. If it takes 15-30 minutes or after the bike cools some I would look at an ignition coil. Check to see if it has spark next time it quits.

I'm looking at buying a 1994 CB250 with 45,000 miles on it. It has been well maintained. Is that mileage a deterrent, in terms of future maintenace costs? Secondly, was this model made in japan, or...


The model plate on the frame neck will tell you where the motorcycle was made. If the bike is really cheap (under $500) and in great shape it is probably a good deal only because most riders only put 2000 or 3000 miles a year. If it lasts 10,000 miles, your can drive it 5 years with out too much trouble. Keep in mind you can probably buy a brand new 250 cc motorcycle for around $4000 new or With low miles for $2000 to $3500. Example : last winter I purchased 2009 Suzuki DR200 with 100 miles on it for $2400 (new $3899). It gets 80 MPG, will comfortably run at 55 mph, and will go on or off road This fall I purchased a 2009 EX250 with 900 miles on it for $2500 ( new would have been $4199). Stock it will do 100 MPH and get around 50 to 55 MPG, regeared it should get 80 MPG. Look hard in the off season to get good deals. Whether your 94 CB 250 is a good deal or not depends on the price you will pay compared to a different low mile used one or a brand new. If you have $4000 to $5000 to spend there are some great deals on 500cc past year, brand new, with warranty motorcycles on the showroom floors. Check it out.

Backfiring


Sounds like you've got a carb with a clogged jet. My guess is that the surging was a moment where the carb was actually operating well enough for the bike to run properly on that cylinder. Could also be a spark problem but you should be able to determine if this is the case rather quickly. I'd probably go ahead and replace the plugs if you haven't already...that could help...but my guess is still going to be carbs.

Fuel Efficiency


have been religious about break-in and will pass 500 miles by the end of the day. I’m getting about 14mpg less in urban and 20mpg less in highway than EPA estimates. I generally cruse between 2200 and 3800 RPM rev once when taking off from a stop and rev at each downshift when stopping. These are lifelong habits and have serious doubts that my engine’s drinking problem is substantially related. Does anyone have an isea why my bike is 34% less fuel efficient than Buell advertises?,I just picked up a '08 XB12R at the start of the season, and was getting really bad mpg the first 1k miles also. I just hit 3.6k miles and am getting about 130 miles to the tank riding hard. Id say give it till 1k-1.5k miles before giving it much worry, during the break in period its going to be low.,,,
