Title: Bike locked up on me on the freeway Post by Liamgeraghty on 04/16/13 at 14:26:04 I was cruising down the 405 at around 60 miles an hour when all of a sudden my bike starts braking for me I was on the throttle not on brakes I have no idea how it happened. The bike still starts up and I rode it just a little to see if it would roll. If anyone has any idea what locked up on me I would appreciate the input I |

Title: Re: Bike locked up on me on the freeway Post by verslagen1 on 04/16/13 at 15:00:21 sounds like the piston seized. got oil? wait for it to cool off, gently ride home or get it towed. |

Title: Re: Bike locked up on me on the freeway Post by Serowbot on 04/16/13 at 15:21:11 Get the wheels up off the ground, and see if they spin freely... Could be engine,.. could be wheel bearings, brakes, rock in the belt... I had a turn signal fall off, and wedge between the rear tire and the swingarm... I felt the power drop. and the bike slowing,... I saw a trail of smoke behind me 1/4 mile long, and I thought the engine seized... It was burning sidewall rubber against the turn signal... :-?... |

Title: Re: Bike locked up on me on the freeway Post by Liamgeraghty on 04/16/13 at 19:54:29 Yeah the bike is still running just fine I haven't gone farther then 1\4 of a mile cus I was knocked off my bike going 60 and the pipe cought fire but everything still seems to be working just fine don't see any belt damage so I'm thinking rear brake just locked up somehow. Thanks for your input though I appreciate it |

Title: Re: Bike locked up on me on the freeway Post by Trippah on 04/16/13 at 20:02:51 If you don't see any obvious reason for the brake/rear wheel to lock up, take it to a reputable Suzi dealer...you will not get a lot of second chances at 60mph and funerals cost more than a whole new bike so please spend your money wisely. :o |

Title: Re: Bike locked up on me on the freeway Post by Jiggyfly on 04/16/13 at 20:20:58 I would lean towards rear brake. If you were "knocked off", I'll assume you mean hit, or fell.....if it was on the exhaust side, I'd guess the exhaust jammed against the cable/rod, & the rear brake is stuck in engaged. |

Title: Re: Bike locked up on me on the freeway Post by Liamgeraghty on 04/16/13 at 20:49:54 Yeah within a couple seconds of it locking up my buddy hit me with his bike. |

Title: Re: Bike locked up on me on the freeway Post by Liamgeraghty on 04/16/13 at 20:50:34 Also what oil should I use for that bike I forgot what I put in last time |

Title: Re: Bike locked up on me on the freeway Post by verslagen1 on 04/16/13 at 21:15:42 after that I think I would of forgotten where I parked it. |

Anything Jaso MA rated with at least 1200 ppm of ZDDP Best bang for the buck that meets this and is available just about anywhere is the Rotella 15w40 dino oil in the gallon size white jugs or if you prefer full syn Rotella T6 5w40. Both of those are available just about anywhere and are very low in cost and meet the needs of our flat tappet style engines and are wet clutch approved as well as Jaso MA rated. Plus since you change your oil every 3K miles it just doesn't make since to use $15 per qt oil on the top brand name full syn since our engines don't have the sump capacity nor the filtering capacity to fully utilize the extended drain intervals that you would normally use with such an oil like that.

Tell your "Buddy" to follow at a safe distance.. Would be a good time to change oil. Drain into something clean & inspect the oil for aluminum bits & ferrous bits, IOW, drag a magnet thru it & shine a lite at it, maybe even pour it thru a paint filter, or Tee shirt. Mite wanna autopsy the oil filter, see whats in there. |

Title: Re: Bike locked up on me on the freeway Post by Serowbot on 04/17/13 at 16:33:28 Something I just learned.... If the rear hub becomes overly worn, (probably from from over-adjusting the brake, or wearing it down to bare metal),... the brake arm can overcam and lock up the rear... Liam,... your rear hub isn't heat tarnished to bronze,.. is it?... (That will mean, the hub has seen extreme heat from locking up)... |

I am not sure but I do know that the rear brake was squeezing alot whenever I would brake hard so i will check that out tomorrow but that could be a possibility. We had just went on a 90 mile ride that day so it was Definatly used a lot that afternoon. Cus I know the brake arm still works and what not but need to inspect the actual pad itself |

Title: Re: Bike locked up on me on the freeway Post by Bubba on 04/18/13 at 09:15:46 geez...this guy locks up his bike at a clip, gets knocked off by his riding buddy and is talking like it's no big deal...I'd be sitting on the couch drinking beer for a week after that! anyway, only time I've had a lock up it was on a 2-stroke and it wasn't going fast but stopped me pretty quick...piston seized...just sayin' bike started back up and ran but when i pulled the jug off it the piston was smeared pretty bad... |

"I was thinking Poston could of seized as well.

Just my 2 cents |

Title: Re: Bike locked up on me on the freeway Post by Dane Allen on 04/18/13 at 14:40:37 Can I get some clarification on the "pipe caught fire" part of all this? Exhaust pipe? At the muffler end? At the head end? In the middle? Did something get on it or was it so hot the chrome/wrapping/whatever burned? Could a valve in the wrong position be strong enough to stop the piston in a single stroke, power stroke after intake but right before or during ignition? Just throwing out ideas? Could a blockage in the muffler, including raw fuel that then ignites be enough back-force to stop the engine on the exhaust stroke? Or a bad baffle that recreates the "banana/potato in the tail pipe" joke. It's the "pipe caught fire" part that is throwing me off.... |

Since the fire is unrelated to the lock-up then the brake over-cam explanation makes sense. |

First thought from me is he had some sort of "event" at running speed. Type of event could be fuel, electrical or braking which would all fit the symptoms as noted. Electrical is by nature intermittent and he won't see that again for a bit. Something cut his engine off abruptly, which could be accidental kickstand actuation, kill switch wiring, etc. etc. etc. Fuel can be intermittent but generally isn't brutally abrupt. It will happen again, then he can provide more appropriate information. The evil vac sucker will always out itself, always. Brakes, just have him check the stamped line on his rear brake lever star shaft (the actuator shaft) and see where they point inside the marks on the rear hub. Making him take his stuff apart isn't really required, now is it? If I was a super low skills brand new newbie, you might not get any really accurate information from me first off the bat. All I might be able to tell you on the first time is "something unexpected happened" and seemed to heal itself on the way home. I would be able to do a better job describing it next time it happened, because I would know a little more and I would be waiting for it to happen this time. |

Your rear brake is activated by a lever, that then rotates a cam that is basically a rectangle (with rounded ends)located between the brake shoes. The narrow side of the rectangle is between the shoes, and as you step on the brake pedal the rectangle rotates and causes the shoes to spread apart and push on the brake drum...and the brakes shoes pushing on the drum causes friction.....and slows the bike down. "Overcam" is a situation where the brake shoes have become so worn, and the adjustment has been cranked in so much - that the brake cam (rectangle) can rotate more than 90 degrees and get locked into position....so that the brakes will not release. This is most likely to have occurred while applying the brake hard......not while just riding down the highway wiith your foot off the brake. Where you applying the brake when the sudden stop occured? Your orignal post made it sound like you were just riding at a steady speed while the event occurred. It is time for you to do some work and look your bike over. Everyone has given you some things to look at and check. Get your homework done......then post again and let us know what you found. |
