copemech Posted May 15, 2013 Report Share Posted May 15, 2013 One may cap off the overflow tube on the bottom of the bowl, your choice. Quote Link to comment Share on other sites More sharing options...
crazy_dave Posted May 17, 2013 Report Share Posted May 17, 2013 Hey Greg, I was just curious if you tried out your friends GG? I’m very new to trials riding and bikes. I just got a 05 REV3 270. The other day I went riding with a guy that had a GG 300/310cc or something pro and we traded back and forth a few times. I liked the riding position on the Beta much better and the power was more linear on the Beta. The GG hit a lot harder when it came on the pipe, I almost looped it a few times. It was a lot like riding an MX bike vs. a woods bike. I’m just wondering if Betas are in fact more linear or do I have something wrong.lol Quote Link to comment Share on other sites More sharing options...

It's brand new though so i was taking it very easy, but i would say i found the beta a bit easier to ride and identify with the observations you make. Some how the beta just felt a little bit smaller, but I'm sure i could get used to the GG easily enough. It was a lot smoother and quieter too.

greg watts Posted June 17, 2013 Author Report Share Posted June 17, 2013 I may have had a breakthrough. More news as things unfold... With the excellent help of John at Lampkins and Beta Italy I discovered that very early 2008 bikes (and mine is one of those) needed a small mod to the carb, basically a little brass insert that reduces the size of the overflow tube in the float bowl. That and shortening the overflow and breather tubes and putting a little slit in them about 20mm from the carb to stop the syphon effect. However, the parts kit is no longer available, so after a little bit of effort, Beta Italy sent me a replacement (used, but who cares?) float bowl to the correct specification. I was well chuffed! The bike does now use less fuel and it's a lot less 'bogged down' when you need to blip the throttle on a descent. I am now going to play with the jetting as I'm pretty sure that at my elevations it is running a bit rich, so I think I am starting to get somewhere with this now. Happy days (I hope). :-) Quote Link to comment Share on other sites More sharing options...
