My son's beta Evo factory 2019 has got tech forks. Should there be two spindle wheel spacers. I have one on the caliper side and no spacer on the right hand side. I've noticed a little play on this side.
One school of thought is that young very good riders now ride 125s for too long. In Raga / Bous case they didn't, they will have been on 300s at 16.
In my experience trials in the 70s, 80s and 90s (my era when Britain produced many world class riders) there were over 150 riders entered every weekend, full of families. Trials these days are full of solo's with the odd Father/mother and Son/daughter team. There is no soul in the sport.
Some Youth riders have support, but many talented riders don't . We've been there!
If you want world class trials riders we must find ways of encouraging youths to continue with the sport and not venture into mx/enduro, football etc.
We now compete in mx where entries are full and competition is very hard, but you get a sense of a big family! I've not had that in trials for years!
You never know it might bring some money into the sport !!!
Hello, thank you for your help. I brought the bike thinking it was a 349 frame with a 348 engine. I guess it is a complete 349. My wife has confirmed the engine number as being 51 H 00221 . It is a sidecar outfit!
It was running spot on, and then started seriously back firing. I think we've traced the problem to being a worn keyway ignition side. I've got a couple of ideas how to fix it, but fear it will need a new crankshaft. Do you know where I can get a crankshaft from , also, anybody to fit it as i don'tI have the skills/tools to do the job. A picture of the beast. Thanks
Hello, can anybody help? I have a montesa engine number of 51H00221 . I've looked at engine and the serial numbers and the 348 should start with 51M. Im Confused! Any help appreciated as I need engine parts, thanks.
Thankyou for everybody's help. I measured the carburettor and it's a 28mm Mikuni. So i dn't think its that. Going to to address tha timming, points and condensor, also the leak down test next. Cheers
I would do a leak down test, before buying a new carb for that beast..
Hello, it's a great bike. What is a leak down test? The bike ticks over but as soon as you want more revs the bike backfires and fluffs big time. Not rideable. Tried a 24mm carb from a fantic and ran slightly better, but still not rideable . The carb on it is unrecognisable. No numbers. Cheers.
Hello, I've recently purchased a 348/349 montesa cota! The frame number is 51m20333 and the engine number is 51m00221. Can anybody help identify what model and what engine it has? I want to buy the correct sized carburetor for it as it runs very poor! Cheers.
Yes mate, we have a bongo which carries my sons big wheel beta 80 in the back, and my bike on a Dave cooper rack on the tow bar! Bomgo.. What a great bit of kit!
