  1. A friend of mine has just purchased a nice C15 for Classic Pre 65 Trials. It ticks over evenly, pulls well at the bottom end, but runs out of puff when being pushed up a hill climb . I’m sure it needs a larger main jet, but I’d like to get the whole settings right , from Amal carb type to all jets , needle and slide. Thanks everyone.
  2. Well, a new float and needle jet seems to have fixed it. Had it running for 20 mins, stopped it a few times and restarted it first kick without the need for plunger tickling. Rode it 2 miles on the road. But I will look at a heat shield. Thanks for your help guys. PS . It was exceptionally hot the day of the event 28 degrees, well, hot for the UK.
  3. I’ve recently purchased a 1965 Tiger Cub. It’s been bored to 220cc. The previous owner has fitted a new Amal Premier carb 622 /301. 103 needle jet. 130 main. 19 pilot jet ( 2 rings on the jet ). slide 622 / 3.5 no numbers on the needle but two rings on the top, set at position 3 ( lowest ). The bike starts ok, ticks over fine but at a trial on Sunday it displayed all the features of fuel starvation mid section. In two sections she just stopped and wouldn’t start until I depressed the carb plunger as if starting from cold. Then fired into life. Strangely she was fine between sections, no hint of starvation. Baffled to say the least, just hoping to compare setting with anyone running an Amal Premier. Lastly the carb is cleaner than a clean thing. No obstructions. Thanks all.
  4. OK FOLKS IVE GOT A 2022 TRS ONE R. IVE DONE THREE OIL CHANGES ON HER AND EACH TIME SMALL GLOBULES OF SOMETHING COME OUT TOWARDS THE END OF THE DRAINING ON TOP OF THE OIL. NOW IM WELL AWARE OF THE ISSUES OF SEALS IN THE WATER PUMP AND THE WEEP HOLE IN THE CASING. NOW ONCE ALL THE OIL AND THE GLOBULES ARE IN THE CONTAINER THEY DISAPPEAR. IVE EMPTIED THE OIL INTO A FLATTER LONGER TRAY TO GET A BETTER LOOK. NO SIGN OF THE GLOBULES. IVE THEN INTRODUCED A SMALL AMOUNT OF WATER AND SEPARATELY COOLANT INTO THE SAME OIL. THEY INSTANTLY DO WHAT YOU WOULD EXPECT , THEY FORM SMALL GLOBULES IN THE OIL. SO THIS WOULD INDICATE THAT WHATEVER IT IS COMING OUT OF THE GEARBOX ISN'T WATER (WHICH SHOULDN'T BE THERE ANYWAY) OR COOLANT. THE OIL IS A WELL KNOWN BRAND OF 75wGEAR OIL. HAS ANYONE EXPERIENCED THIS , OR CAN THINK OF A CAUSE. IM GOING TO CHANGE THE SEALS AS A PRECAUTION. THE CLUTCH WORKS PERFECTLY. CONFUSED. JUST TRIED TO UPLOAD A VIDEO BUT ITS TO BIG, SHAME AS IT SHOWS IT PERFECTLY. ILL TRY AND CROP IT.
  5. Thanks. This is my fourth 4T and the first job I do is split all the connectors, clean them, reattach and secure them. Quite a poor design, they’re all loose and just flapping about 👍🏻
  6. Thanks Glayne, does it matter which wires +/- from the battery I attached to the two wires from the fan.
  7. Hi everyone, I have a 2018 Beta Evo 4T. The bike has been unused for 8/9 months. I ran it today and found that the fan didn’t kick in. I tried to move the fan by hand but it was very stiff. I put some penetrating fluid in to try and release what I thought was a seized bearing. I managed to get it to moving but when the engine was run up to operating temperature the fan didn’t kick in. I checked and cleaned all the connection, all were fine. Can someone advise me, is there a way to check the fan independently or by bypassing the thermostat. I’m pretty sure the fan motor has gone but would like to check before committing to a new one. Thank you.
  8. IVE JUST REBUILT A 1964 TIGER CUB AND ITS HAD THE ALTERATION TO THE FRAME WHERE A MILLER CYLINDRICAL OIL TANK IS FITTED. I KNOW THE TIGER IS A WET SUMP ENGINE BUT CAN ANYONE TELL ME HOW MUCH OIL GOES IN THE TANK. A SET AMOUNT OR FULL. THANKS
  9. DID YOU GET AN ANSWER TO THE CARB JETTING, IM TRYING TO SET MY MIKUNI UP.
  10. Thanks Woody, knew you’d have the info. It’s got a K44 needle, would that be right?
  11. HI, DOES ANYONE RUN A 250 SHERPA ON A 26mm OKO CARB. IM JUSY TRYING TO GET SOME BASIC SETTINGS FOR IT. THANKS.
  12. That’s it now with the Alloy tank rather than the fibreglass one piece tank and seat unit. It’s to nice to get damaged.
  13. Just to reignite the Ducati thread and Pre 65 discussions, I’ve just bought this. Just wondering how many Ducati trials bikes are in the UK?
  14. I notice your a long term 4t fan Billy, what oil do you use?
  15. IM CURRENTLY REFRESHING THE ENGINE ON A MATES 325 BEAMISH. IVE SPOKEN WITH THE VERY HELPFUL STEVE PITT AT THE BEAMISH OWNERS CLUB ABOUT SOURCING AN 81.00mm PISTON. I KNOW THERE ARENT ANY AT THE MOMENT, BUT THE OLD ADAGE SAYS IF YOU DONT ASK…………!! HAS ANYONE GOT AN 81.00mm PISTON SAT IN A WORKSHOP DRAWER THEY BOUGHT YEARS AGO , JUST IN CASE AND NO LONGER NEED, OR AS AN ALTERNATIVE I COULD MAKE A SET OF 80.50mm PISTON RINGS WORK ON THE EXISTING PISTON SHORT TERM. IM ALSO A BIT CONFUSED AT THE OPTION OF THREE DIFFERENT BASE GASKETS THICKNESSES AVAILABLE FOR THAT MODEL. HOW DO I DETERMINE WHAT THICKNESS I NEED. THE ENGINE IM WORKING ON HAS THE 250 HEAD ON IT WITH THE APPROVED HEAD GASKET/SPACER THAT CORRECTS THE COMPRESSION RATIO. THANKS EVERYONE, FIRST TIME IVE WORKED ON A SUZUKI.LOTS OF SPANISH AND FANTICS BUT NOT A BEAMISH 🙄
