So, the other day i dumped my 05 blast on some loose gravel at about 20mph. Afterwards she ran fine. But in town the next day the bike started Grinding BAD and giving a horrible noise and eventually died. IV had problems with my shifter peg becomingloose and now the bike won't start. My buddy thinks the "bushel" (?) In the connection of the shifter to the tranny is out and causing to much play, causing the grind. What do you think?? | ||

To ask the obvious "is the shifter loose"?. 2nd would be "Is the shifter 'maladjusted'?" In other words has the bent shifters position made it more difficult to shift? They've made the Blast to take a drop well and it does unless you've replaced the shifter toe peg with something besides stock. Then you might be more likely to have internal damage. | ||

It sounds internal for sure. The toe peg was already bent from a prev owner. Hadnt gotten a new one yet. No bueno | ||

The recommended procedure here is to do the shift pawl adjustment, refill the primary with a 20W-50 full synthetic engine oil, adjust the primary chain (loose) then do a clutch adjustment. All shall be well, it is hereby declared! | ||

Loosen primary, and clutch at adjuster and handle, then do shift pawl and then clutch, then adjust primary 14 flats out from torque value. EZ | ||

I bought a used Blast, low mileage, but used as a Riders Edge Bike. I knew it had a transmission issue when I got it. The issue was that a student (?) had fallen off the bike and the gear shifter had been banged really hard. Since the engine wasn't running (or the transmission wasn't spinning) the shift fork couldn't move the slider into the next higher gear. This caused damage to the shift drum. See photos below - When the drum was forced it deformed causing a dimple to form, this dug into the shift fork making it very difficult to shift.  You can see that the shift fork was also damaged when the shifter was forced attempting to shift into higher gears.  You can see the huge gash the deformed shift drum made in the shift fork, it should be all smooth in the journal area. A roll pin engages the shift drum to the shift fork, this causes the shift fork to move back and fourth moving the shift dogs to engage the appropriate gear cluster. Anyhow, the parts are here and it's back on the mend. Cost to repair, $500.00 in parts. - Bee | ||

Very cool write up!  Thank you. | ||

Take a few more picks of assembly if you can. They are hard to come by, especially for a Blast. | ||

Here are a couple more photos - If you ever wondered, this is a Buell Blast gear cluster  In this photo you can see the gear dogs that engage. In this case the a little knackered!  | ||

And more - A Blast Engine with split cases split. Showing crank Shaft and bearings. Gear clusters on the left - in hand.  The Buell Blast (as all Buells) of this era have a jet that sprays oil into the bottom of the piston and barrel for lubrication.  Camshafts live here. Our Blasts have roller tappets. Pretty cool. Also, the drive for the oil pump (and pump) are seen here.  - Bee | ||

Weird seeing that cam cavity missing two cam holes, and missing the crank! $500 in parts huh? Must have been a lot more replaced than you listed, or that shift drum must be stupid expensive. I smoothed the raised lips on my M2 shift drum and put it back in, it worked well. I didn't have that kind of impact damage though. | ||
| Bumblebee |
Yes, everything was stupidly expensive. A couple of gear clusters, shift drum, three shift forks, top end parts, bottom and top end gasket set... $Ouch$ | ||

Just to give closure - it's all back together and runs like a champ. I also installed a new speedometer sensor, as the speedometer didn't work...I kinked the fuel tank vent hose causing the engine to stall when you needed it most, (getting on the freeway!) and the ignition timing was a little off - although I did set it with the LED method...with the strobe it was about 4 degrees retarded. This really helped with the big flat spot off the line. All fixed and good.  All back together. The things you get on eBay...here it is in it's Barbie-esque cuteness. - Bee | ||
