    300 SS

    I assume you could port an engine to make it easier to kick over. Would raising the exhaust port make it both smoother off idle and easier to kick?

    300 SS

    I have had a couple of short rides on SS 300s, the last was a 2020 so they are still available. They were both smoother than a 300 factory model I owned....very smooth. In general I find the Betas 300s to be a bit slower reving and therefore a bit easier to ride than the 250s but can't explain why...unless you wind them up. I did not wind up the SS so can not comment on that. The most surprising thing about them is that they were very very easy to kick over, nothing like other 300s I have kicked, maybe even easier than 250s. I looked up the specs and the compression ratios are the same so I can't imagine why they are easier to kick unless the listed specs are wrong. The 2020 was also quieter than other Beta's even though the muffler looked the same. Maybe there was something different about that one bike.
  3. When I try to message I get: rgvlc cannot receive messages.
  4. Evo is different from 2001 Rev3.
  5. I'm looking for a flywheel weight for a 2001 Beta Rev3 270. These are 80 mm hole to hole as opposed to later Rev3s that are 70 mm. Did these also require a spacer for the side cover? I was looking at making one myself but there is not much space under the side cover. I'm in the US.

    Beta 4t carb

    Where do you get this aftermarket airbox to carb conn which is softer? I never timed it but maybe it is a 45 minute job vs 15 for the two stroke.
  7. On Beta's, 200, 250 and 270 all share the same bottom end.
  8. With the forks removed from the bike, does each individual fork tube compress and extend as expected?
  9. Assuming they worked properly before mounting on the bike, something could be out of alignment. General recommendation is to loosen all bolts except lower fork clamps. This includes fender mount and axle clamp. Flex forks up and down. It should be free. Tighten top clamps, repeat flex, then axle clamp, flex, then fender.
  10. Were the forks extended when you put the top caps on?
  11. When I had flooded the crank case, there was one indication. While kicking, it kicked back a bit. I don't remember if this was when it was finally trying to start or not. It was likely trying to compress some fuel. In my case, I probably pumped the excess fuel into the exhaust. Per the posting above, be very careful with any spark. I once had an 80cc 2 stroke engine filled with gas and you could not even kick it over. I was in a hurry and did not think about spark. It spit out a surprisingly large about of gas and caught on fire around the third kick. It was a good size fire but I had an extinguisher in my truck. My daughter was about 8 at the time and this was to be her fist ride on a bike with a clutch. I wish I had a picture of her face when I pointed to the bike covered in black soot and extinguisher powder saying ..you can ride it now.
  12. Is the plug wet? I have a fairly new to me 2001 270 easy starter. I went to Prairie city last weekend and it was a no starter. There was spark but a wet plug and not even a burp from the engine. After a plug change and lots of WFO kicking if finally lit and puked a fair amount of gas on the back wheel. I had forgot and left the petcock open. I wonder if the Mikuni is more sensitive to leaking than others. Is the plug dry? The idle/ pilot circuit in the carb is likely plugged up and requires cleaning. A crude method to try is, with petcock on, lay the bike on its side for 30 seconds or so to flood the carb. Stand it up and kick with throttle off and choke on. I don't know if it makes a difference but I also noticed that a projected tip spark plug is factory recommend the early Rev3 .
  13. I had a some success quieting down an 2001 270. It is not a night and day difference but there is a noticeable decrease in sound. The bike had a megaphone shaped spark arrestor and I swapped it out for a John Deer style. The link shows the type but I'm not sure it is the exact size. There are 2 or 3 sizes. https://www.ebay.com/itm/Lot-of-2-NGP-49024-AM108146-Exhaust-Muffler-Spark-Arrester-Screen-Type-1-3-8-OD/162488243183?hash=item25d50dd3ef:g:2NIAAOSwWWxY~Wzt Second, I put on a rubber 90 degree elbow on the end of the exhaust so it points at the ground.
  14. Those things shear very easily. I wonder what percentage of people shear one the first time servicing Evo dog bones. I bet they sell la lot of them.
  15. I did some investigation and comparison with another TY175. Most, it not all of the stiction was due to the fork boots. They look like OEM but were some no name boot from ebay. Once I cut the boots off, it feels pretty good.
