Death barble. You have to take the jet tower apart, blow out the two passages and best to replace the oring. The Oko version is a better fit. Good luck.,
Well if you go to the Italian World round and the TDN you could report on A 17 year old from my club. The gal winning Expert is too busy in her internship to become a doctor, she has competed 3 times at the TDN. And our longest riding women finished the Scottish in the late seventies. Most women competing have interesting stories and our president of our club is of course a women. She does an outstanding job, besides her property is one of my favorite practice areas. Also her daughter has ridden the TDN and is currently in Washington D.C. as part of an internship to become a lawyer. Not bad from nowhere in New Mexico.
Our main club is NMTA and we have 14 girls/women that currently compete. Ffom junior through Expert. And one of those riding Expert usually beats the boys!. Our
Club averages about 75 riders an event.
Diagrams copied how many times in 50 years. LOL It helps to understand mechanics of 2 strokes in the first place. We went decades with barely any real information, except the one between our own ears.
I think you are talking about a thicker base gasket. A black tube throttle and a 9 tooth counter shaft might help. Also getting the soft setting for the clutch helps too. It`s a fine bike from a build quality stand point, but the front end is just to light for us humans.
Perfect for the GP riders like Raga.
Ha I found this post again this a.m. So I just happen to have a complete motor my boss gave me last night. It was pulled straight off the frame, so it still has the radiator, wiring harness, clutch master cylinder and all levers. Shows 68 lbs. so around 64 lbs motor only.
The Beta was imported to America by Cosmopoliton Motors starting in 1985. From '85 to '89 they were quite a popular bike in the trials community. We probably had a dozen or more in our club. You sill not find many around as they were rode to death. If rode hard the frame would break around were the coil mounts. Mine was rewelded 3 or four spots. At the time the bike made quick power, but the rear disc was quite a poor design and the rubber kit had to be replaced often.
I spent two decades riding Beta's after my first tr34.
Easiest solution would have been to buy the correct tire. https://www.rockymountainatvmc.com/tires-and-wheels/irc-tr-11-trials-tire-(tube-type)-p
You will always be fighting the issue with a tubeless on a DID tube type rim. On the ty 80`s I drilled 8 holes in each side of the rim and screwed the tires to the rim. I always use a bead sealer. https://www.amazon.com/Steelman-G10106-Tire-Bead-Sealer/dp/B00NBTGCF4/ref=sr_1_59?crid=OVD6WK9CN290&keywords=tire+mounting+lube+and+sealer&qid=1659102586&sprefix=tire+mounting+lube+and+sealer%2Caps%2C138&sr=8-59
