hello there, i have just bought a ty250, with frame number #493-30---- making it a 1977 model but road registered on a "C" as first registered in 1986/7. i am hoping to do some long distance trials (LDT's) if any one has any advice on setup etc. many thanks phil

hi, sounds like a gearbox bearing. drop the oil and have a look for any nasties in the oil, but really i think you will need to split the crank case to see whats inside. that way you will know what the inside of the engine is really like. not a very dificult job, only bit i had done profesionally was the con rod kit fitting to the crank shaft. i bought an ebay mono a few years ago. cut a long story short..... rebore/piston, little end, con rod kit a few bearing and a second hand gearbox from ebay. now runs like a swiss watch. good luck phil

hello all again, thanks for the many replys and advice, i have now bought a nice little twin shock and after a little fettling should make a great LDT bike! its a 70's ty250 yes i know not british but it is road registered and the brake and gear levers are on the right side!! parts shouldnt be a problem and road maners can be geared up without loosing too much off road ability (yes maybe not able to do monster trials climbs etc but i dont think i could anyway!). and enough money left over to maybe get a bantam in the future when the xr is sold :-) win win situation!! that is if the fettling doesnt cost too much! thanks again all and pictures when im on the road and trailing :-) phil

hello again, yamaha serow. yes great bike i have had a couple, one of the best bikes i ever owned, still got one although for some strange reason i have supermotoed it! ok to help with the decision i will tell you what i have got at the moment. xr400. think i will sell this to fund next bike gasgas ec200. love this bike but dont use it enough and the resale price would hurt me too much ty250 mono. ebay bike costing me more than i thought, just getting back together after near full rebuild husqvarna wr250. another one of the best bikes i have had. xt225... undergoing a supermoto makeover. a scooter for shopping and a couple of kids bikes... xr100 and py90 (chineese crap that looks good but keeps going and going). so the next bike i want to do some green laneing and some LDT's etc, must be twin shock and have decent road capabilities, not worried about super trials ability. more of a gentleman's green laner with a bit of class or style. i think an old british bike would fit the image in my head. regards and keep the suggestions coming, i still have my eyes on a bantam or a royal enfield at the moment. regards phil

thanks for the replies, i guess i will probably buy a 250 - 350 four stroke then and then do a mild trials conversion. after careful consideration that seems the best option. i already have a ty250 mono that i was considering getting road registered but the seat is so low and my knees just are not up to constant standing and sitting down with such a low seat. i have been looking at some nice 70's 2 strokes just to further confuse. thanks again phil

hello all, please help me with my decision. i want an old british long distance trials (LDT) (or reliability trials as they were called back in the day) bike, not too worried about super trials ability. but should have reasonable road manners and able to cruse along at about 50mph (or close as possible). so would a 175cc 2 stroke be better than a 200cc 4 stroke?? i dont really want a full on trials bike more like a pre 65 green lane bike that i can do some LDT's on or should i be looking at something like a royal enfield 350cc 4s, james captin 200cc 2s an ariel or something completely different. please dont say an xr400, thats what i will be selling to fund this project. kind regards phil.

hi, i just rebuilt my 59N engine, she started up on 3rd kick last night. after 2 minuets and a little adjustig of the FA mix screw, ticks over like a grandfather clock. piston is a Wossner 1983 IT250, had to file the very bottom 2mm off the piston skirt at the corners to allow clearance for the flywheels at BDC. otherwise a very very good piston! con rod renewed, dont know what bike model but obviously an exact match. all bearings and seals replaced. bought a compleate G-box from Fleabay (very good condition) and the clutch was good anyway. all in all i recon i sepent
