  1. Keihins are prone to needing an occasional cleaning. The exit hole for the pilot circuit is tiny as in microscopic. Yes it looks bigger if you eyeball it (the little hole in the bottom of the carb bore behind the slide) but it necks down significantly. Even a tiny bubble of water in that hole will make it bog coming off idle. Best to pull it apart and run some carb spray through the holes. Usually clears it up.
  2. Fans, and electric motors in general, have a very high starting current. If jumping across the temp switch makes the fan run every time then I think you’ve identified a bad switch. If you have an ohm meter handy you could let the bike heat up and disconnect the switch and throw the ohm meter across the switch terminals. It wouldn’t take more than a few ohms of resistance to limit the starting current to the point the fan won’t start running but would keep running once started. I did take a Beta fan into the lab once to measure the running current and it was about 0.5 amp but if I limited the supply to anything under 10 amps the fan would not start. I think you’re up for a new switch.
  3. Machine wash warm/warm. Pretreat with stain stick according to instructions on the stick. Let the stain stick sit for a bit before washing to do its thing. Do NOT dry in dryer. The heat will set the stains. Also the heat will shrink the spandex. Air dry.
  4. All on hold due to corona virus. Will update when the world starts spinning again.
  5. New England Trials Association has cancelled all events until further notice. Pretty much everyone is in agreement that it is unfortunate but prudent.
  6. Unfortunately they are not doing an event this year. At least not an NETA event.
  7. I'm not dead yet. Still looking for another gig. Would you like cheese on that sir?

  9. I’ve had two of the 300s and my experience matches mcman56’s most closely. They can be made softer off the bottom with modifications. Proper jetting, gear down a bit, low compression head and carbon reeds on mine. Purrs like a kitten and grunts like a pig. But... it is still a 300 and will remind you of that fact if you get sloppy with the throttle. Lose focus and you better have a quick clutch finger. I haven’t tried super smooth but I have had Betas with added flywheel weight and I just don’t care for the run-on you get with a flywheel. I also like feeling for traction with a more responsive engine but to each their own.
  10. I considered this.The problem is my bike was popping out of first and second into neutral. That it usually occurred when I bounced the bike (intentionally or unintentionally) started me toward the shifter but I came to realize it wasn't synchronous with just a bounce but a bounce that unloaded the transmission. I'm sure there are nuances that I'm missing. The other thing that pushed me away from the lever being the root cause is it takes (or should) a fairly decent amount of force to roll that bearing up the cam slope far enough to de-index the thing. More than is likely to be generated by that light weight shifter just bouncing on the pegs in my novice sections.Third was that my bike was the best shifting Beta I've owned until about six months in. Then it started getting funky. First the occasional pop into neutral and progressing to two-three times per event. Really rattled me. So far with the latest revision of the mod I have half a season of riding on the bike with the custom cam and reverse cam indexer and it is still working as it should. I know when I do a crappy shift and now I can hear and feel the gearbox snap into gear after a split second. Just using the indexer with the proper bearing stopped it from popping out but the slightly steeper cam with flats on top has just changed the feel to what is expected from a Japanese street bike. I'll tear it down in spring just to make sure it is not wearing abnormally or anything weird is happening like the pins backing out of the cam but to be honest it's so good right now I don't really want to mess with it any further. Without evidence to the contrary I'm still sticking with the crappy, oversized OEM bearing, under-sprung indexer as the root cause.
  11. Congrats and welcome to the loony bin?
  12. Not quite sure what that phrase means but... You might want to pull the primary drive and have a look to see if something is interfering with the clutch basket. Typically a loose muffler core won’r make the bike vibrate.
  13. Looks like I’ll have more time to play with this stuff. Just got made redundant. Can’t complain though. It was a good 37 year run.
  14. But? But the new Beta has bold new graphics! BOLD NEW GRAPHICS!!! How could you?!! ?
