I recently bought a 2003 blast, and it runs and idles just fine, but I notice it doesn't sound quite right, I get a lot of buzzing and strange noises. This weekend I am going to open up the primary because I tried doing a primary adjustment, but I can turn the bolt in easily by hand until it is bottomed out, so I have a new primary shoe and spring on order as I think the old one is worn out. I'm having shifting issues where I end up getting into a false neutral when shifting into second from time to time, and when down shifting into first it will make a clacking type of noise as if someone put a playing card in bicycle spokes. Could a loose primary chain be causing this? Or should I go ahead and pull the clutch basket to do a shift pawl adjustment while I have the primary open? Also, when I bring up the rpm's The bike starts buzzing and makes all sorts of strange noises, I think it could be coming from the headlight/gauges though, I understand that as a single cylinder this bike will vibrate quite a bit, but does the buzzing sound like it could be a mechanical issue? | ||

Naw - the bike makes a lot of bizarre sounds, most are normal - go 25 flats out instead of 5 and you'll be fine. Check the header for loose nuts, and in general check the whole bike for loose bolts. Get a manual at buellmods.com, do the shift pawl, make sure drum pins are no more than .335 and if more put a drop of red loctite at base and gently tap in till that length, chamfer stator wire protection plate, replace Detent plate and replace clip with two detent clips, do the clutch adjustment just a tad past a 1/4 turn out from soft bottom, and then just ride it.

Concur, mostly. Get the primary chain tensioner sorted dout and that will make a HUGE difference. Use caution if you're not mechanically inclined before you dive into the transmission. Proper idle and clutch adjustment will solve most grinding, clinking and hanging in neutral issues. It's not a Jap bike and the trans shifting is a little clunky, especially when cold and much worse without proper clutch and idle adjustment. When adjusted it should shift fine, very well after the pawl adjustment (if you decide to do it at this time), BUT it's not a dirt bike. Jam it into gear and you're asking for A LOT of trouble. A firm shift is all. | ||

Thanks EZ and Gearhead! I actually did a clutch adjustment last night and replaced the primary fluid, it is shifting way better! When I drained the primary there was only about a quarter of a quart of fluid in there, so I'm sure a lot of my problems were coming from that. The weird thing is, when I first did the clutch adjustment (I followed the manual and BCriders instructions word by word) The clutch lever got super stiff and it was disengaging the clutch without me pulling the lever in. I had to take off the clutch inspection cover and redo the adjustment about 8 times before things acted as they should, but once it did work, it was like a dream! I still believe I need to replace the tensioner shoe, because I could see plastic shavings in the primary fluid, but now for one more question; If I drove the bike around for a few more days until the shoe comes in, do I run any serious risks of damage to the bike? Also, I have the parts on order to do the "friction zone service bulletin" on order so it is a little easier to teach my girlfriend how to operate a motorcycle, will doing that fix rob me of power in any way or cause clutch slippage? If anyone has done the friction zone fix, feel free to chime in with your experience | ||

Yes, riding that way can do damage. It could tear up the inside of your primary cover and it could break the upper 'chain guard' (I can't remember what it's called), which means you'd need to buy another. Since the primary chain case fluid also lubricates the transmission, having a bunch of tiny pieces floating around could also do damage. Or nothing could happen. Just not really a good idea to do. | ||
