XGecko, there was one more change to the 2001, it was the addition of a lean angle sensor it is a switch that cuts power to the ignition if the motorcycle is leaning beyond 55 degrees. | ||
| Xgecko |
you are kidding right???? I have seen many of those types of sensors give false readings that truely F#!@^p the machine they are supposed to protect. Not to mention the recent race ending example of one on Anthony Goberts R7 | ||
| Dann |
No, I am not kidding, my reaction was much the same as yours, it spooked me enough to bypass the switch. The correct name for the part is the Bank Angle Sensor. | ||
| Xgecko |
yea well I'm glad I have a 2000. I can think of a few turns that the road is already banked that I would trip that sensor on Just what I need is to have the engine cut out because I like to turn | ||

There was also a change to the cam gears in '01 ... high contact ratio was added to the connection between the cams. '00 had HCR at the pinion connection only. | ||

I believe there was a minor difference towards the front of the frame between 00 and 01. My 01 parts manual makes a distinction. I'll double check and clarify... -Saro PS - Hoss - I've spaced on that Flytrap. I'll mail it as soon as my ugly mug can remember! | ||

Dansherman - how could an under seat pipe be a slam against Buell? Personally I think it makes a lot of sense, becuase of how low the Blast is, by moving the pipe out from under the bike you gain almost 4 inches of ground clearance. Not a lot, but I hate smacking my pipe on various road obsticles. You could mount the catchpan on without any major issues, and the way the frame of the Blast is designed, the header could easily slide across the top of the motor, and then angle up under or next to the seat. And the lower unsprung weight thing, most hi flow cans I've seen weight less than 6 lbs tops, and if you shortened the tail for a single rider, it'd still bring the pipe in close enough for it not to matter.. MO, only.. [Ds] | ||

I believe the sensor in question is a "tip-over" sensor not a "bank" angle sensor. In other words it is a gravity actuated device. When leaned over in a turn it should not trip. | ||
| Sarodude |
DS- The exhaust scraping phenomenon is very likely due to the marshmallow somebody stuffed between the swingarm and frame in place of a proper shock and spring... -Saro | ||
| Dansherman |
[Ds] - High-mount pipes wouldn't be a "slam" against Buell at all. It just doesn't fit with their design philosophy of "Everything that's heavy belongs in the middle." I agree that the clearance would be a bonus, but I've really only scraped my pipe once. I think underseat pipes are one of the coolest things you can do, along with single sided swing arms. I just highly doubt that Buell would ever produce one, even as a concept bike. That's all. (PS) I got my stickers today! On the paper they didn't look that great, but once I got them on the bike they look amazing!! Pictures to come soon. -- dan | ||

Though a replacement for the shock is available I will not change it until someone comes up with new springs for the fork. I'd rather ride a sponge than half of one...balance is more important to me than stiffness | ||
| Sarodude |
Tony- I do believe there's a little known set of springs (from Works?) that fit up front. Matty - you out there? -Saro | ||
| Rd350 |
Saro, Works who? I have been looking for springs for the last 6 months. Give us some more info.... | ||
| Xgecko |
oh no  now you've done it I had decided that I wasn't gonna do anything to my Blast until after I move to Japan...new springs huh...those will be fairly cheap if the race springs for the S1 are any indicator | ||
| Rd350 |
Xgecko, How is the oil you using working out? I have been using Castrol 20w-50 and it works great. Got tired of H-D wanting to much money for cheap oil since it as the big H-D on it. I have been thinking about using Mobil 1 syn.. Heard that the graskets don't like syn.. they start to leak more than normal. Anyone using syn.. in the bike and having any problems? | ||
| Dann |
Blake, please clarify. How does a gravity activated switch know the difference between tipping over and leaning over. The official Buell part name is Bank Angle Sensor by the way. I tested it in my garage one day and the engine did stop long before the footpegs on my rearsets touched the floor. It is calibrated to stop the enginge when the lean angle exceedes 55 Degrees regardless of conditions. I undestand the philosophy of a tip over sensor but this switch will kill the engine no question if you are on a safety course and fall over or sliding through a turn. Not ideal circumstances for engine to stop, right? Another switch is the sidestand safety switch. Before disabling that I could not go over 75 MPH without holding me foot on the sidestand. | ||

RD350 I've been running Mobil1 in my bike for the last 2000 miles. No leaking, no problem. Jim | ||
| Mother_Big |
ditto | ||
| Dann |
Underseat exhaust? Good supsension? Tires? On a Blast! Argh!! If Eric Buell were here he would shoot Lightning bolts from his eyes and Firebolts out his arse! | ||
| Xgecko |
I have been using Mobil 1 15w50 synthetic or Chevron 20w50 synthetic for going on 11,000 miles now. I haven't noticed any leakage and relatively little burn off compared to fossil oil. I will likely take the oppurtunaty to change the tranny oil in another 1500 miles to Mobil 1 75w90 (probably July 4th unless I decide to do a few round the island trips before then) That "Bank angle sensor" would have killed me on my favorite ride I get low enough to scrape the pegs on a few turns and I have rearsets  The side stand switch doesn't bother me nor has it ever given me a problem but then I still ocassionally try to leave with the stand down so it saves me from doing something stupid. | ||

I believe it was Power Sports News that sent a newsletter out last week concerning lean sensors, and how it contributed to a crash on a track...I think there was a link on how to bypass the sensor. Unfortunately, i deleted the email after i read it, I laid my bike down last October, and have gotten no where near a 55* lean angle since..I value my skin more than i value agressive riding. I also look a bit closer to see if there are patches of sand before I hit a turn  | ||

Dann, Call it what you like, but the switch is gravity actuated. When leaned over in a curve, cetrifugal force acting along with gravity acts downwards along the vertical axis of the bike just as gravity alone does when the bike is balanced upright. There is no difference as far as the switch is concerned except that the force is greater when leaned over taking a curve. When the bike is tipped over gravity is acting partially transverse (sideways) to the vertical axis of the bike. When the transverse component reaches the critical magnitude, the switch trips. It's a simple mechanical switch actuated by gravity is all. Example: Take a normal light switch like on your wall. Glue a 6" length of coat hanger to it so it effectively extends the switch lever. Tape a couple quaters to the extended end of the piece of hanger. Now balance the switch so the piece of hanger with quarters on top is oriented vertically. Now start to tip the switch in the direction towards it's other position. At some point of equilibrium where the switch's spring/detent action is overcome by the weight of the quarters, the switch will throw. Now hold the switch so the piece of hanger is again vertical, balanced perfectly with gravity and so that the quarters must fall towards you to actuate/throw the switch to its other position. Hold it at arm's length. Now sit on a piano stool and start to spin. As you begin to spin, slowly start to tilt the switch so the quarters lean towards you but put no force into actuating the switch. Spin faster and continue to lean the quarters toward you keeping the quarter balanced with respect to the piece of hanger. The faster you spin the more you need to lean the quarters towards you to maintain balance. They are leaning well past vertical and past the point at which when you were not spinning they caused the switch to throw. The same thing happens as you lean your bike when negotiating a turn.

Anthony Gobert had a hell of a tank slapper (looking anyway) that he recovered from but the shutoff did just that and they could not get his bike started again I guess Yamaha's version really kills the ignition. BTW if you haven't seen his recovery it's a must see. Everything you said Blake is true...the problem is that there are circumstances where that type of sensor can be fooled. In some cases a good stoppie or a shifting wheelie will cause such a sensor to trip and then you are dead in the water on a stoppie (probably) no big deal on a wheelie that could be deadly. I had an instructor in my Electronic Imaging class say "never let a machine do what you yourself can do...chances are that you will do it better and many times faster." I am suspect about letting a machine, or in this case a sensor think for me. I'm glad I have a 2000. | ||
| Dann |
My heart still beats in the turns now with the switch not in the current path thank you for the physics lesson. You are really reaching with this one. How in the world could I keep them quaters taped on in the rain? | ||
| Dann |
Blake one more question. What happens to centrifugal force when you are SLIDING in a turn. | ||
| Dann |
Rockbiter, I also look closely for obstacles ahead which causes me sometimes to make evasive manuvers, cause not all trucks in Chicago are required to use belly pans. Some spill sand, fuel and unmentionables in the path you just made a pass on minutes previous. | ||
| Rd350 |
Thanks everyone looks like I am going for Mobil. | ||
| Rd350 |
Xgecko, forgot to ask you how was the fit and finish when you got the Corbin seat. Did it go right on or did you have to work on it? I am hearing stories that they do not fit as good as stock. I am going to order one next week. Just want to hear your view on it. | ||

Blake - Hmmm that's a great discription, but please tell that to my Blast.. it just ain't listenen'.. I took my Blast out into the sand/dirt roads/military tracks around ELP, just to a chance to see why everyone has been using this little bike in the dirt tracks. I can see why! It's an ungodly amount of fun to got into a corner at full throttle, bike leaned over at a 45, the pegs digging a rut as deep as the spinning rear tire.. I had great fun until I leaned it a bit too far, slid to much, and watched as my beloved P3 decided I just wasn't as much fun as the dirt... After the dust cloud had settled and I walked over 50 feet to the Blast, which was prone, and STILL RUNNING.. I picked it up, blipped the throttle, and drove on. No damage to the bike at all, the sand was forgiving today, the clipons dug a bigger rut then the riding pegs.. I own a 2001 Blast, and I have not disabled the Bank sensor (I think they are a great idea, they should work exactly as Blake stated!) but the one on this (my) Blast does not function.. at least like it should. I really question what it's there for.. (hey, I could shave another .2 lbs, that't like.. .003 more HP!) Saro - Ahhhhhhhhhhh yes.. the rear marshmellow.. how I wish to hold it over a campfire and watch it glow.. Tony - Yes! There are front springs availible, I can't comment on Works, (though I did see an adjustable rearshock that might work with the Blast), check also with RaceTech, the forks that the Blast uses can be tricked out a bit. I've seen a spring swap, heavier fork oil, and the gold inserts put in them, but really I'd like to get the dimensions of the triple trees to see what we could swap the front out with. I rode a ZX-9 the other day and dual front calipers just give me the heebee-geebee's.. [Ds] - doesn't care, likes the undertail muffler And is verrrrrrrrrrrrrrrrrrry dizzy after trying Blake's experiments.. Physics Rules! | ||

Speaking of forks.... I have been restoring older bikes with my father since I was a wee small boy and the Blast! happens to be the only motorcycle with hydraulic forks that does not have an oil drain that I've ever laid a screwdriver on. What's up with that? |
