I have my 93 Climber running! It started on the second kick! Ran good, a little rich. Clutch was stuck, typical Rotax, I fixed that on my SWM with new fiber plates. Took awhile but it finally freed up. The clutch felt either on or off so new plates should help. Gearing felt fine, power was good, lots of compression! It needs to be jetted better or another carburetor ( I have had great luck with OKO on my SWM)!

2022 Beta EVO 80 Senior: It's a fun, reliable little bike for an older rider to practice and improve his basic skills.

Hi All, thought I'd get a fun conversation going about which bikes we love and why. Here's my list: 1996 Beta Techno. Representing something quite different from it's competitors with suprisingly modern handling. 1997 through '99 Montesa Cota 315. The best bike of it's time in many ways 2000 Bultaco Sherco. These early bikes were a bold statement of intent from Sherco. They meant bussiness. 2005 Sherco 320 4T. An absolute weapon. 2005 Montesa Cota 4RT. A bike that has since become the most winning bike in the history of Trials. 2009 GasGas Raga Replica. Possibly the best colour scheme of any bike to this day. 2009 Beta Evo. A beautiful bike and a massive performance improvement over the outgoing rev3. 2010 Sherco 3.0 Cabestany Replica. A great looking bike with a new chassis, a bigger engine capacity and a cool colour scheme. Seeing someone else on this bike convinced me to buy a sherco (a mistake). 2012 Ossa tr280i. A short lived but technically groundbreaking bike. 2015 Vertigo prototype. A attended the 2015 SSDT in which one of these bikes riden by Dougie Lampkin won the event. 2017 Beta Evo 4T. My own bike and by this stage a very well sorted and fun to ride machine from Beta. What are your favourites and why?

My jumbo has a keihin but I had to fit a sleeve to the outside of the carb to make it fit the inlet rubber. The dellorto i took out had a similar fitting so perhaps the inlet rubber has been changed

I have found the OKO`s to be very good. They are a PKW copy. Only buy the ones made in Taiwan though. There are Chinese ones out there which are crap!

Who is getting fed up ( or is it only happening to me ) when ordering parts from trials shop web sites , pay for the item . Only to find out that they dont have them in stock and they have to order the item in . So youve paid for the part and no clue when the item will turn up for you ! So tell me why are these shops advertise and sell stock they dont hold ?

In case they have not told you, the pressure plate only goes on one way. On the clutch one of the posts will have a notch in the end of it. That aligns with a mark on the pressure plate. Good luck.

Not been to Belgium for years. Won't ever forget it - got lost on some back streets on a weird one way system with the sat nav frozen, so just headed east thinking we will get to a main road eventually and find the way out. Annoyingly builders wagons kept stopping every few feet, and it was 7am - there was no traffic delays why did they keep stopping?.....then I looked at one of these tall houses, and realised we were going through a red-light zone! 😂 That turned into a frantic escape of the area, honking anyone that stopped to move! But otherwise the country was very nice and would have liked to discover more of the rural areas. Will get back over there one day I am sure.

I assume this is cheap pwk copy? I have fitted a koso to my m159 (325) Bultaco, after bit of jetting it runs well. When I fitted it it flooded and I had to bend the float tang to cure. I only really wanted to see if it would work as the standard Bing was stuffed. I know people will say they are rubbish, but it is a cheap way to test if a Keihin would work

It might be A but it sure aint I.

Anyone used the nibbi carb as a replacement..? The Amal MK2 2627 on my TR77 needs a complete rebuild including a New slide. I can buy the nibbi And a selection of jets cheaper 🤦‍♂️ do I replace or rebuild

???? Is this some Ai crap.

Colomer. Pronounced Colom air. I seem to remember Woody Hole starting this Colome rename for some reason known only to himself while doing the commentary for Bennett Trials Videos in the 1990s.

Not sure if this will help but having a slightly dirty potentiometer can act like that I would think. I've used both Magura and Domino on several bikes and I don't recall that either one uses a hall effect sensor. You can observe the "dirty" signal as an erratic ohm value when tested disconnected from bike. A 0-5k pot with three wires will read about 5k ohms between two wires regardless of twisting position. The third wire is the signal where you would observe the erratic resistance across it and either of the two other wires. Its a simple metal wiper (signal) that moves across a fixed wire wound 'fixed' resistor. But it could be a hall type non-contact also used a lot. I've seen quite a few 'dirty' reading throttle pots and they usually are near the lower throttle position, likely due to more wiping at low throttle.

I talked to Dirt Riders and told him BS i got from seller(you have to let the clutch warm up before it will disengage) He had heard it before and told me 1. crankcase had been contaminated or mixed disk was not installed or installed wrong. Waiting on a clutch now

Yep i knew it is 301 iv’e got the parts book just thought that number majesty gave me inthe link cross referenced, your right tony it doesn’t fit they’ve got back to me, i must be able to get one from somewhere last time i tried sherco themselves they didn’t even reply🥴 anyone else got any ideas?🤞

Link to parts books from Splatshop SE 4.5i-F * 2006 Looks like you're after part number 0301 which is nothing like what is used on the trials bikes Stand Holder End 450 this should be the part

Thanks majesty for the link, iv’e just messaged them to confirm it fits cheerz mdeerzp

Send a self addressed envelope to Vertigo?

I used to see Jon at trials in the Cotswolds (of course!) but I've not seen him for at least a year. Maybe he's retired from trials stuff.

Hi, I’m looking to purchase an autograph of Marc Colome for my collection, does anybody know where I could get one. Thanks

The few bikes I have had a go on with different engine modes didn't really ride a lot different just had the power come on stronger in a different location in the RPM range. Just for consideration. (never had a go on a Beta with an S3 Header and Arrow so can't speak to that exact setup though) Good luck. PS. Best trials bike modification I have ever had a go on was suspension setup for myself.
