So I'm pretty sure my bike has worn first gear dogs. When cold, the first gear doesn't seem to catch or get into gear readily. If I take off and accelerate a little, the bike will jump and the transmission will clunk. It may even do it more than once until it actually catches. What's the protocol to change this? Any recommendations? Shortcuts? Should I get just the piece I need or go ahead and replace the whole deal? Any help would be appreciated. |

In all honesty, I would do all the recommended things first, adjust the shifter pawl, adjust the primary chain, adjust the clutch and refill the primary/trans with a 20W-50 full synthetic oil and then put about 10,000 miles on it. What you are experiencing is a common complaint with the Blast. |

What do you mean put 10K miles on it? Is that how long its supposed to last w/ a worn dog? Or are you suggesting that I just have an unadjusted transmission? Ive got 25K miles on it already. that make a difference? |

Concur. How many miles does your Blast have? Considering that changing gears or almost all transmission work involves splitting the cases, you might want to try everything else first. Its also a good time to consider any serious mods (like a 600cc big bore) since you'll have everything apart. As far as what to replace, that up to an inspection to determine. Some parts may be visibly 'bad'. Others may not look bad. If someone does a lot of the M2/Blast/Sportster transmissions they might be able to tell you what normally wears out on them. Splitting the cases is a lot more work than most are willing to (or can) do. I'd decide how much you really love your Blast and proceed accordingly. FWIW: Older Sportster engines (which is more or less what the Blast is) had a trap door for the transmission which meant you could just pull the trans out. This would be a different discussion if that were the case |

Many dont have 25,000 miles on their Blast. Have you done all the other suggested adjustments? (Message edited by Gearheaderiko on February 27, 2012) |

Yeah i know I've got quite a bit. technically I've only put like 1500K on it cuz i just got it at the end of last year. but right now its at around 25,000 miles. No I haven't done all the other adjustments except adjusting the primary via sound method. I will absolutely try those first. Could you direct me to where i can learn about adjusting shifter pawl, clutch, and changing transmission fluid? |

Shifter pawl adjustment is in the repair manual as is the fluid change and clutch. Not to be a richard about it, but you really need a repair manual especially since you are even remotely considering pulling the transmission and going to do all the adjustments. Any year repair manual will do. Often on ebay. Use the search function at the top of the page. Takes a little practice, but thats all I'd be doing for you, to find the appropriate information. But the manual has all the pictures and cross referencing, etc. |

Thanks. I have a service manual on my computer. But when it comes to specifics, its not that great, pictures can be confusing, and usually there is at least an elementary understanding requirement about what you are taking apart. Since I have never even seen a clutch or pawl i was hoping for some 'real person' involvement. And i did do some searches but didn't find anything too specific. Sometimes you guys have nice how too's and pictures and since you guys are probably the ones that were either doing it or involved in the discussion, your recollection of what the thread was named or even consisted of is far more efficient than my reading dozens of threads looking for something to help. But i will definitely keep looking! |

Sorry, I cant be more specific. Maybe EZ or Swampy can point you there because one of them probably wrote something up about it (I know I didnt or dont remember doing so). I dont know what your mechanical backround or aptitude is, so I dont know if some of these 'fixes' will be outside your current abilities (no offense, I just dont want you getting in over your head). I do know the threads can be very confusing and you're right, I do have a better idea of where to look. Sorry I cant be of more help right now. |

My friend - for the most part Blasts are pretty bullet proof, with the only Achilles being the boot. What you see in these archives is probably 10 percent of the owners - usually those with an issue caused from a previous owner. If you check the Blast KV section, both under primary and procedures sections are threads giving helping hints and details - sorry guy - the rest is up to you - we can help, but we can't hold the wrench for you or the beer - even if offered - the net you know, if you lived near by, come over, with parts, etc, and we could take a swing at it - not hard, tedious maybe and exacting - none of its hard to do with the proper tools - and there are few specialized tools needed.

Course not EZ. I defiantly understand. And there is no offense taken gearheaderiko! Please don't think I'm upset or demanding! Tell you the truth, I have very little mechanical experience. I consider my self a very quick learner however and even just reading discussions by you guys and quick clarifications have brought me from never seeing the inside of an engine to feeling confident about carb work, head, or cylinder work. You have no idea how much I have learned since the last 5 months (since I bought the bike). Considering I bought this bike (oldish and high mileage) primarily for gas saving and secondarily to learn how to work on bikes and learn how to ride, I feel I made an excellent choice. With that being said, riding a motorcycle was once beyond my background or aptitude (5 months ago). Taking off a gas tank, also beyond my background or ability. Taking apart an engine (as simple as the blast is) also very much beyond my mechanical ability and background. Carb work? even more so. But as stated, all of you here have been irreplaceable in my learning and growth with mechanics. As far as what goes beyond my abilities? anything I haven't ever touched, fixed, or learned about before. Hence, taking an engine off of a set of wheels will be my biggest endeavor yet. Will it stop me? likely not. Is there a chance I will screw it up? of course. But i feel that a little over $1G (price I paid) is a small price to pay for the knowledge I can learn from a costly mistake (much cheaper than medical school for damn sure) As always, I just ask questions to learn what I can. And when I feel I know at least a little, I go ahead and give it a shot. Please don't apologize! All you guys have been an immense help and great teachers. I can only extend my virtual gratitude! |

As for tools. What specific tools are you talking about EZ? |

a piece of metal - steel is good - 4 1/2" by about 1 1/2" - with the short edges beveled/rounded. Torque wrenches - Ft lb to 200 and inch lb to 144 or so. A cheater bar comes in handy as well. EZ (Message edited by ezblast on March 04, 2012) |

Very cool, Jjcool! Confidence is everything. But dont forget patience and if you have a digital camera, takes lots of pictures and notes. It will prove invaluable should you get stuck. It may also help us to help you. |
