Wondering if any regulars of this forum would be able to give me a little insight, as I was posting pictures before it said the file size limit was 3.5mb, now it is telling me its 2mb which is too small for the resolution of the photos I currently have, is this something that resets or if anyone has any input I would appreciate it😊

Thank you! I wish I knew more about the pictures but there was nothing written on them. I am actually not sure who the gentleman in the yellow Jacket is as my Uncle is the man in the 2nd picture leaning on the 1 bike smoking a cigarette with the M49 closer in frame

Looks like I've reached my attachment limit here on the forum so no more pictures unfortunately. Not completely satisfied with the idle on the bike, it's slightly erratic. Suspecting possible leaking jet block gasket - got one from Jetsrus.com so I'll hopefully get that installed tonight.

Rear sprocket guard also installed... any of the newer sprocket guards from the pro models will also fit these older bikes in my experience.

Front brake rotor guard from TheTryalsShop in New York is installed....

Thank you. I'm going to try them or the ARC levers.

A Full face MTB helmet is safer to your teeths and more ventilated. But, yes, too light for motorcycle helmet? They have MIPS technology and people in bike take serious jumps at much higher speeds than us.... The truth is: Trials helmet stopped on time and innovation is required by users for sure. Who will fill the gap???

Check if Trial solutions has them for Beta.

If the same as mine, where they go into the hub they are M6. Bear in mind though that they are special shouldered bolts

Welcome Shaun.

Hi, does anyone know where I can buy short clutch levers and brake levers for my 2023 Beta Evo 300 SS ? Greathings, Luc

Thank you Marky, i will look into those

The two major crank seals are built into the main bearings. The left side has an additional seal between the main bearing and the magneto. You'll be removing the engine and splitting the cases. This video from Jim Snell shows how...

I would recommend trying to source some OEM main bearings with in-built seals. Back in 2015, I had to rebuild my 2011 300 (due to cracked cases). I was advised to replace the mains with the new Xiu Engineering "low friction" bearings which were a good bit more expensive than OEM. Big mistake - within three months the bike was billowing smoke because the crank seals had failed. I had to rebuild the engine again but this time with new OEM bearings. I've not had a seal problem since. But to answer your question, the OEM bearings are fairly tight - hard to rotate with oily fingers while holding just the bearing. But the crank should rotate fine. The Xiu bearings felt much the same from memory. Yours sound way too tight. You run the risk of them spinning in the cases. It the left one moves at all, the oil holes won't line up. Unfortunately, sourcing OEM Gas Gas mains might prove difficult these days.

Hi, i've just recently bought a second hand Beta minitrial 20, electric Beta, for my daughter, to play around in the garden, and see if she likes it or not. Bought the bike second hand, so it has a little work to it. Chain and sprockets are worn out. Now, i do not seem to find a sprocket set for a reasonable price for this bike, also, it has a very narrow chain. I've seen a conversion on youtube were they use an Oset chain kit for this bike, but it seems like there a lot less teeth to the sprocket doing that conversion, so the bike will run a lot quicker, and loose a lot off torque. I've seen bigger Oset sprocket aswell, but how do i know wich one to order? I would like to keep te transmission ratio as much to stock as possible. Does anyone over here now what chain and sprocket kit can be adapted to this bike?

Love the looks of the M49, pretty bikes. What intrigues me is what appears to be numbers tucked into the back of their hats and the man in the yellow jacket also appears to be wearing Dunlop trials wellies. Brilliant atmospheric photos.......

Thank you for the warm welcome Ron! I hope you are able to find the Yamaha you're looking for, those sound like excellent memories!

I had a 1974 Yamaha TY 250 when I was a kid and loved it. I’ve been looking for one to restore myself but without much luck. They get snagged before I can get to them. It’s the sound of the engine that I remember most and when I see a video on YouTube with someone riding one around I get all choked up hearing that very unique, quite quiet, popping rhythm. I wish you the best of luck getting your uncle’s Bultaco back into shape. I’ll keep watching for your updates.

The 1st anniversary of his passing came around and I put in my first order of parts with Hugh's Bultaco. The first order was mainly just basics I could tell from an outside look including a full gasket kit with crank seals, carb kit for the Amal 627, air filter, a spark plug boot, and some rubber bits that were all dried out) which arrived quick! I then started tearing down the bike, starting with the air filter I just received an error that I am over my picture amount so I will have to add more another time!

Hello everyone, after a long break, divorce, house move and recently an operation, I'm getting back into trials my nephew wants to learn so its inspired me to take it up again i now live in Oudenaarde, belgium so if anybody near me knows of any good practice terrains close by that would be great. i know there is Genk and its a really great training site, but its not just half an hour down the road so will wait until he starts getting the hang of it before going over there. i would like to say hello to Guy if you are still on here, been a long time mate, hope you are fine. and hope everyone else is fine too.

One of the old pictures wouldn't fit in the last post, and it's the one I think is the coolest with all the bikes! I also saw a gentleman selling repop signs on Etsy and purchased one for the shop wall

While going thru pictures I found quite a few cool ones of the Bultaco and various trips he had went on. With the rough cleanup done I decided that I would work on the bike once I wrapped up another project I was currently working on. I would never repaint it as it is in such nice original shape, however I would tear it down and go through everything from top to bottom to make sure it was riding ready and use it as a little toy in my wood lot The bike sat quietly under a sheet until fall of 2025, with it being uncovered to show many people throughout the year and quite a few kids taking pictures with it at various gatherings

Hi everyone, I posted in the welcome area but thought I would start getting this thread caught up to where I am currently at on my restoration of my Bultaco Sherpa T 250. I have done many other restoration projects but this is my first motorcycle project The bike was originally purchased by my late Uncle Bud on August 21, 1970 (I have the original bill) and he used it mostly as a hunting bike as he had other bikes he used in trials riding. Fast forward to while I was in high-school it turned out my science teacher was the son of the Bultaco dealer for our area and knew my Uncle well From what my Dad told me Uncle Bud was 2nd or 3rd best in all of Ontario in numerous championships at the time. Time passed and the bike sat since I believe the 1980s. At the end of 2018/early 2019 Uncle Bud gave me the bike before he got sick, and I always told him one day I would fix it up. At that time I was 21 years old and in college and didn't have the funds or time to embark on fixing it. Due to his illness Uncle Bud's memory faded and I had his tired bike in the corner as I took car of his property/small farm and said I would fix it up. He ended up passing away in October of 2024, I left work that day and went to reflect out in the shop, and knowing that his celebration of life would be hosted within the next few days I rolled the Bultaco out and spent hours detailing it to surprise both my parents and our family I am still trying to learn the process of this forum so I hope I added the "barn find" pictures correctly And this is ready for the celebration of life
