It did not do this before the change. Used proper torque on axles, and loctite on front. Regarding the pinch bolt, the only thing I did different than per manual, was put the caliper back on first, then remembered to tighten pinch bolt.
Nothing rubbing on tires...
Pirelli Diablo 140/70P-16, and 110/70-16
Did not remove rear sprocket, but when I was looking, the black was worn off in the torx heads, so I'm wondering if the place I took them to did... |

what is the rear tire pressure set at? Is it rubbing on the swingarm? |

Spin the rear wheel and watch the pulley for any wobble. |

Pressure is at 32. Did not see any spots where it rubbed. Will check again tomorrow, and also for pulley wobble... But as for now, I have a date with my pillow... |

Tires should fit fine, but sometimes with the oversized rear tires, too high or low a tire pressure can cause them to rub.

Well, no pulley wobble, no rub spots.. Tore front completely down again, and restarted from step 1.. With caliper off, tire spins as free as can be, and took a few minutes before it finally stopped on its own.. With caliper and pads on, it spins, but slows to a stop quick from pads rubbing. It was a gradual stop though, not a lock the brakes up stop. No foreign material on/in pads.
So, reassembled step by step per manual. Used the low end of the torque tolerances, in case my wrench is high. Even made sure sprocket screws were to torque, in case they did take it off..
Experiencing some rain here though, so can't test ride until probably tomorrow night. Any bit of rain is too much rain for me to ride in...haha..
Really hoping it was just a chance situation of what was wrong, and disassembly/reassembly fixed it.. It's going to be nice Tues. and Wed., and would be nice to take her work... Like I said though, I didn't really feel it until over 55mph.. so..?  |

You didn't take the bearings out of the wheels and they didn't fall out either?
You didn't have to beat the axle in or out of the wheels?
You didn't adjust the brake pedal or lever?
I'm at a loss as to what else you might have done, unless its a running problem and you're misdiagnosing it as brakes/wheels.
I too would like to ride my Blast to work, but a random ignition problem prevents that. Not that I worry it will stop running. At least then I'll have a chance to find the problem! I just need to have my trailer ready to go if it goes. . The last thing I need is to have to dig a trailer out of my garage when it's 1am in the morning and I'm already an hour late for work 
Not that the Blast is my only choice, I just hate riding the shiny bike if its going to rain. The Blast is an all weather ride!! |

Did not take bearings out, nor did they take themselves out.
No hammers involved.
Did no adjustments.
It very well could be engine/tranny related. I based my theory that it's not on the engine noise not changing. That's also mixed in with 60 mph wind on me, and therefore not an exact science. Also, because I (obviously) just had the tires/brakes off.
Well, I suppose this is a good way to really get familiar with my Blast... |

Did you check the clearance between the tire and the lower shock mount?
It may spin fine on the stand but when you are running 60mph there is centrifical force that acts on the tire causing it to get larger in the center. Check for clearance at the lower shock mount on the little bracket that protrudes towards the tire. If it has been rubbing take the wheel off and with a big hammer beat the bracket flush with the swingarm. There are pictures around here somewhere to show what I mean. |

Clearance is good.
Possibly a breakthrough though, (and I'm gonna feel bad for wasting your guys time and knowledge if it's right).. IF it is a rubbing problem, I've been looking too low.. A few weeks ago, I took the piece of the tail I cut off, and mounted it upside down underneath, to cover the wiring. I can't be certain if I rode it after that or not..So, sure enough the tire has rubbed it a little bit. Possibly at 60mph with centrifugal force, and small bumps..
Now, if this is enough to cause my problem, I don't know, but the best lead I have yet...
too much work, and not enough sleep I guess... Either that it's all the drugs I never did... |

"PS did you do anything (anything) else besides remove wheels and replace tires?"
Yours wouldnt be the first time for this problem. Its possible it could cause your symptoms. But license plates rubbing on rear tires from modifications (and incorrect stock installation) is very commonplace with relocated mountings.
lets hope you found your problem |

SO.... It's not rubbing anymore... Which is good... Except it still has the original symptoms... Which is BAD...
This is what I noticed tonight though:
Rattle in the front end
Excessive liquid in my filter/catch coming from crankcase breather
My breath was pretty bad in my helmet
So, my new plan of attack... Change primary oil, adjust primary, pop a tic-tac.... |

I am concerned that you may be starting a shotgun approach to repair: fix everything and hope your problem goes away. Spend more time trying to diagnose what is exactly going on.
Too tight a primary chain can cause 'lurching'. It's uncommon that most will feel it though. But...
If its a new problem it isn't likely the chain unless you or someone recently adjusted the chain.
Is it a running problem? Is the engine actually hesitating or hitting a flat spot in running?
Does the bike actually bog down? Like some just tied a rope to the bike and is pulling you back?
Spend the time trying to figure out exactly what it's doing before 'fixing' anything else. As evidenced by the license plate, things can go wrong and have unforeseen consequences.
Is there anyone else who can take your Blast for a ride and see what they feel? |

I can tell of nothing wrong running wise, by sound and feel. Engine noise remains constant, and I don't feel extra hits or misses in vibration from motor.
I guess you could say the bike does bog down..Not the motor... As I said, it feels as though the brakes were applied for a split second, and I feel a slight slowdown, and a drop in the front end... Only lasts for a second, and occurs every few seconds, rhythmically.
This only happens at the high end of 4th, low of 5th, at around 55mph. I figure if it was an engine problem, it shouldn't be limited to higher speed, and I would still feel it in lower gears...right?
As far as the shotgun approach, I see your point. However, I'm not going out buying new parts to HOPEFULLY fix the problem. This was already on my to-do list. I don't think the previous owner did ANY maintenance on this. So, it had to be done anyways, and now I can just rule it out as the cause... |

Anyone have any experience with the Shinko SR568/567 tires, specifically tire longevity? I'm looking at options for next year when I may have to change tires, and the Shinko's are definitely lower priced compared to the Diablo/ST66... |

They last about 3500 to 4000 miles - are considered pretty good, except lousy in the rain.

Ok, thanks for the info. I'm likely going to go with Diablo fr / ST66 rear that I've read so much about. Worth the extra cost for much longer life. I could easily put on 10,000km a year (6 mo riding season) |

Yes - that is the preferred mileage group.

I'm gonna do it again, 2,390 mi to the coast, and I need to change my front tire first. given the embarrassment of options i could use some help from those more knowledgeable. whats the best front tire option for longevity on the highway? I've heard that the front can take a 100/90-16 but I'm not sure what maker and model |

I would never trade handling for longevity on a front tire especially on a Blast and since any out there will easily get 10k miles, easily!
Get a Pirelli. MT75, it's a good highway front or you can use a taller Pirelli if you wish (sorry, don't have those memorized!).
You'll likely replace the front before it's tread is worn out anyway (or you should). |

Time to replace the old Dunlop K330 tires on the blast. On one blog online the guy suggested a Pirelli Diablo 110/70-16 scooter tire for the front and the Pirelli ST66 140/70-16 for the rear and thought you could get like 10,000 miles on both. Found the front tire but I'm a little confused about the rear, is it a scooter tire as well? Can't seem to find it online to purchase. Can you use the Diablo scooter tires both front and rear safely? |

Yes, those scooter tires can be used without worry. However, the 110/70 front is actually smaller than the stock front tire. It's a really great handling front tire and well suited to "dropping" in to turns, but you might find that attribute unsettling as it can add a feeling of instability, if you are sensitive to those things. If it's a highway only bike, I'd get the Pirelli MT75 (stock) front tire. But that's your call. Both Pirellis handle well and can be aggressively run through the twisties and equally track well in a straight line. Front tires will far outlast rears, so always get the stickiest front tire you can. |

I and other twisty riders prefer the 110/70.
Not - I can't believe anyone is still dumb enough to be running the Dunflop.

Thanks for the help Erik. As far as EZblast goes did you just call me dumb? For asking about options to replace the "stock" tires that the bike originally came with? That is why people come to this site, to ask people who know. I can't believe anyone is dumb enough to use this site with a pompous ass like you hanging around to shoot them down. Anything else to say wise ass? |

Whoa there tiger, I said that anybody who continues to use the Dunflop after all the warnings of the various Buell sights qualifies as dumb. You changed it out - aka - not dumb. However, if you think your words are touching me, then your already lost. The stock tire was/is the most dangerous option for the bike and never recommended. The only reason it went on the bike is because HD had a fulfillment contract with Dunlop and used the Blast to fulfill it, then dropped the contract and went with Pirelli.
