Why does the Blast allow the shifter lever to be pressed down when in first gear? Does that question make sens? On every other bike I've ridden, the shifter has a positive stop that does not allow the shifter to be pressed down any further when in 1st gear. This seems to me like a silly omission on a bike targeted at beginners...it makes things more confusing. So what's the difference between that and every other transmission? Can the Blast trans be modified to have this positive stop? |

Andymnelson, what you are experiencing is manufacturing tolerances stacked up to create slop! If you want to follow Ezblasts instructions on finding the correct thickness of dowel pins and replacing the shift drum pins, then replacing the shift detent plate with something from an XB or Baker Trans, you can get that sloppy shifter to go away, but you might loose alot of valuable riding time and seeing that the End Of Riding Season "Event Horizon" is now visible it is probably a good idea to wait till November to make the fix. |

Swampy, I dont think that what he's talking about. Older Harley's/Buell do not have a positive stop on low or high gear (1st & 4th or 5th). It will still move like there is another gear, but will continue without any resistance if there isnt. On newer bikes the shifter will not move any further if in high or low gear. Andy likes the positive stop. I like the old way better. Why? If you're in high or low gear you can easily check to see if you're there. The shifter moves freely up or down with no resistance. If you've got another gear to go, it wont move. The new style, whether or not you've got another gear to go, there's always resistance. Push it too hard and you're going to shift gears. There's a very fine line between the two. Not so bad if you're upshifting, but hitting a lower gear by mistake can have you laying on the tank...or worse! |

Erik you've got the idea. The trans is otherwise great (as far as Buell 5-speeds go!). I see your point Erik, never thought of it that way...never those troubles either tho! I do like the positive stop. It seems easier to find 1st and also to know that I'm in 5th. Not even for me, it's for my girlfriends bike. She was frustrated by it and questioned it and she's never even ridden anything else! So any thoughts anyone? Is there a way to add this "positive stop"? |

LOL - you do know that this tranny design is like ancient - yes? What you want is for someone to reconfigure it for your convenience - short of a Baker Tranny or its price equivalent - its not going to happen - sorry. EZ |

I'm not asking anybody to reconfigure anything. This same trans is in other bikes and they have that positive stop (or whatever you want to call it). All I asked was if anyone knows the difference that causes that stop or not. (Message edited by andymnelson on September 13, 2008) |

If your XB has the positive stop then its probably 'doable', even though the Blast uses a Tuber Buell tranny, but both are very close. This is the first time I'm sure EZ and certainly me have heard of anybody wishing to do this modification. No, I dont know the difference. Since the Blast uses a Tuber/Sportster tranny perhaps someone on the twin side can be of more help. Me, I'd have to search through repair and parts manuals to find the answer. Its certainly not a matter of an optional adjustment. Parts will be needed. I've got both and I'm still trying to wrap my head around why you'd prefer the positive stop. . |

That's cool, thanks Erik. Likewise, I can't wrap my head around why you'd prefer the other Personal preference I guess. |

No one is being an ass - none of the XB's have that feature, and none of the older Tuber bikes bikes as well. The new 1125 does, because its tranny is new. Chill dude. EZ |

By the way, my XB DOES do it. (Message edited by andymnelson on September 13, 2008) |

The XB has a positive stop - I never experienced it, but I never road one with the upgraded tranny - I rode a 2003 an a 2004 - both R's seemed to shift a bit smoother, I didn't notice that, of course I don't own one - hey James is that true - there are other XB owners in this forum as well you know - speak up guys! I was'nt belittling anyone - get off your high horse, and what I said is true of past trannys and Blast because we share the same parts minus the cool trap door. So my knowledge isn't lacking, however, your attitude is. EZ |

Ahhh - don't give up so quick - am searching now - first to find out the real differences between transmissions, and then find what creates that positive stop on the XBs, then see if it is adaptable to the Tubers who would have done it first since their tranny is easily accessible - EZ (Message edited by ezblast on September 13, 2008) |

You're a bit of alright EZ. Apologies for the strong (ans now deleted) statements before. I also have service manuals for both my Blast and XB- I'll do some digging in there and see if I notice anything. |

Hey - I'd really like to know if its doable - I'd do it first time I split the case - I like making things better - lol - but if Swampy's right and it has to do with the detent plate - hmm - that would seem to involve the drum also - hmmm EZ (Message edited by ezblast on September 14, 2008) |

Answer: "I think it still has to do with the shape of the shift drum star." It's a combination of drum design, and the "pins" that the "hooks" engages. When you toggle the (foot) shifter, the arm moves the hooks up and down to grab the pins, to turn the drum to select the gear. All the star does is keep it in the gear selected, and prevent the drum from continuing to rotate. As you shift to 1st, or 5th, there's a missing pin, so the hook can no longer rotate the drum in that direction. The shifter still moves, but it's grabbing air. Later transmissions have a pin there that the hook can grab, but the shift fork reaches the end of it's slot, and so the drum can go no further, thus providing a positive stop. Late XB's are a bit different in layout, but the principle is the same. There you have it - minus the picture - the question is how different is the XB Drum - is it compatible at all with the older style tranny? EZ |

Now it makes sense, the Blast being a RE bike will be down more and suffer more harsh operation than that of other more "Experienced Rider" bikes, if you hit either the top or bottom of the shift pattern and try forcing it what happens? You start to bend things and move things out of adjustment! It makes sense now to not have the positive stop. |

Very true, and since anything that upgrades a Blast tranny becomes a real upgrade for the Tubers as well - since Sportsters aren't using this Tranny anymore also. EZ |
