Before I even started my bike ( I got it in the crate) I had stocked up on a lot of CSP parts. So I installed new triple clamps, skid plate, levers, s3 titanium header. And many bling items in red that I will list later. After this pic was taken, I replaced all the original plastic.

My 301 would never see pivot levers. LOL I tossed the Braktec`s. But then again I tossed most things on my 2021 before I even started my bike. Ajp m/c`s, s3 digit levers, TRS Gold front brake Caliper. Highly modified clutch basket. I have a long list if you are interested.

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.,

The worst thing to watch for is a corrodid water pump and cases. Besides that its a fine bike.

You need better front brakes, that`s where the stopping power is. But the rear should lock up!

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.

The holes go to the intake side.

You need 1/4 inch socket with smaller side walls.

Right hand thread.

Remember when ordering sprockets to pay attention to chain size. 428 and 520 are still sold.

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.

Likely you do not have enough free play at the lever.

Thanks for that, but I have a full supertrapp exhaust.

Go to page 3-8 in your manual and turn the idle adjustment screw 1 full turn counterclockwise. You have to remove the seat to get to it.

Did you ever adjust the idle?

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.

Sorry its the keihin thats easy to loose the needle jet!

You need a bigger pilot jet. Try a 38. P.s check a carb diagram. You could be missing the needle jet.

Put a one way valve on it. Also heat can cause it too.

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
