I just checked my Clymer manual for 125cc engines,TL 71 thru 74 shows piston diameter of 55.97-55.99mm,bore size for those years 56.00-56.51mm. Hope that helps you.Cheers Mal

I will give you the instructions as written in the rider's handbook. A. Freeplay adjustment 1.loosen the clutch lever adjusting lock nut. 2. turn the adjuster in or out to obtain 2-3mm free play between lever and purch. B. Mechanism adjustment 1.Remove left side cover,gear lever if needed.Note position of clutch axle lever under the engine. 2.Loosen the adjusting screw lock nut and fully tighten eccentric adjusting screw.The adjuster is just in front of the gearbox sprocket. 3.Turn cable length adjuster in or out until the lever is positioned slightly behind main axle center line. 4.Back eccentric adjust screw out until axle lever shaft contacts clutch push rod inside engine.Turn adjust screw in about 1/8 turn and tighten lock nut.Readjust clutch lever to get freeplay as required. Hope this makes sense,but is taken exactly as written in the hand book. Cheers Malcontent

was the clutch lever pulled in when it started,could be the clutch not clearing,due to hydraulics or clutch plates sticking together. I have had the same problem when the bike has not run for awhile. Cheers Malc

Hi Russell,Do the bushings need to be reamed,or honed to size once they are installed.If the bushings are a split type this could be the problem.Good luck with the repair.Cheers Malc

Hi,Your brother should check the STRA site which is setrialsriders.org for trials in the southeast parts of the USA. There is a link to the FTA on the site for trials solely in the Florida area. Modern events will allow him to ride his Bultaco on the lines which suit his skill level. Just like in the UK he will be made welcome to ride. Regards Malc

Hi,Just checked in the owner's manual for a Ty250A, point gap is 0.3 to 0.4mm.Timing 3.1m+ or- 0.15. Check that anything that needs to be grounded is,also clean the points with emery cloth while your at it. Good luck Mal.

Had similar problem on a Gas Gas.I removed the brake pedal and push rod,used a T handle allen wrench as the push rod to get full travel from the master cylinder,and bled the air out thru the banjo bolt.Keep the reservoir topped up with fluid,and fingers crossed. Cheers Mal
