Had same issues on both beta 50 and 80. I managed to get the original tap fully open and then fitted one of these in the line. Leaving the original beta one in the always open position.
Had 6 Beta's now. Run them all at 75:1 fuel/oil mix using Putoline Strawberry TT Trial Oil. Used Putoline GP10 gear oil in gearbox and changed it regular. Ran tyres at 4 PSI rear and 8 PSI front. Spark plug NGK BP5ES ... Never had any trouble with this setup.
Hi, I had an issue with a new domino throttle. The slot where the round barb on the end of the cable sits in the tube wasn't formed properly and some times the barb would twist causing the throttle to not return fully and it would rev high. It did this about 3 times on a ride and took me a while to find it as when I restarted the bike it had reseated and all was well. I filed the slot a little deeper so the barb sat right and the problem was cured. Make sure when the throttle is returned there is some slack on the cable.
Hi, I use Castrol TTS oil with super unleaded fuel 70:1. Used it for 3 years in Evo without any problems. I also used it in my Rev 3 prior to that, also no problems.
Hi, I have experienced this on my sons bike, it was dirt in one of the jets in the carb. It would rev easily on tick over, but as soon as you moved off it would die.
Blow through every port & jet in the carb, also make sure you clutch plates aren't stuck together. With engine off, put it in 3rd and rock the bike backwards and forwards. Once the plates are apart drain & refill with decent gear oil. I have always used Putoline GP10 in my beta's and it's worked well for me. Hope this helps.
Hi, my son is the same age and size as your lad. He had never rode a geared bike before so I thought a Beta Rev 50 would be ideal. I went to buy him the bike and when we got there it was too small. I realised a Beta 80 was the way to go. I got him a 2010 Beta 80 (full size wheels) and he has now rode it 4 times. He is already at home on it and the 50 would have been a mistake. I also have a 7yr old lad who has a Beta minitrial, he sat on another lads rev 50 last time out and it suited his size way better than the 11yr old. Hope this helps !
If its mint, I would say you should get more than £2k, there are shed loads of battered bikes out there and in my experience people will pay more for an as new bike regardless of its year. I would wait for the right buyer rather than give it away.
