they do tend to run quite hot as they are set up very lean from factory it might pay how ever to check coolant pump impeller and make sure radiator is clean on the front side up jetting would also improve cooling and performance

inmotion uk , ebay ask on here in wanted southwest montesa america, french classic trial spain

kickstart spring needs looking at ,also the ratchet spur needs to be in a pacific position to give the correct spring tension if not correct you could crack the side casing ,,,you might have a good spark but could be loosing it under compression ( use a car type strobe light with plug in to check ,, if no spark replace points and condensor preferably with one from a car and put under tank

looks like theres a lot of blow by and piston has been rattling in the bore due to excessive wear going by the pics it looks like it needs cylinder re plating and a new piston kit get a engine re conditioner or good bike shop to look at it

new front tyre lean over opposite side to turning, turn slower slipping clutch with rear brake on slightly

they do have a weakness in this area especially if someone left the head mount off some larger cc bikes have a strengthener bar from swing arm mount to head which should help

its no differnt to most 4t engines could be timing chain or if had a lot of use valve guides could be worn

is there any slack in the cable it must be something you have done if was ok before

guy on e bay has them aswell as seals or try inmotion they also have the gaskets you also need to be very carefull getting the kick start shaft set up correct or you will cause damage

undoe the nut on the end poss use impact gun and remove the drive then remove crank poss plastic mallet or press out shouldnt be too tight ,,, what you been trying to run it on swamp water

yes you can start in gear with clutch held in it sounds like your clutch is not disengaging ,if its not this will cause selecting to be difficult will be hard to hold back when sat still or push backwards in gear clutch in ,the clutches on these are quite heavy have you got a good length lever and not a daft shorty ,( sounds like you have a problem other than a lever though ) has clutch arm been modified ,i use an easy clutch helper makes it much lighter manual states sae-10w30 i use atf which seems fine 900cc 30.5 usa floz 31.5 gb fl.oz this does lube the clutch i use 90 to 100 ml synth to 5l

looking good peter

awsome bike if the non restricted enduro model if the jap sr model good road going bike with lot less power ,, they are prone to power valve rattle which sounds like piston slap also noisey clutch goes when pulled in

what are you trying to achieve

are you referring to the cork fibre looking friction plates

whats it like with oil on ,have the bearings gone on square without damage could the shaft be bent ,it seems something is incorrectly fitted or out of line or too much pressure ,are they tapered bearings could do with seeing the parts layed out in order of how they go together

you probably will need to use an impact driver or a heat gun to loosen the locktight

as already stated you need to heat inner race to expand it ,not the shaft as that will have the opposite effect to what you need

piston kit 3 months ago and now the rings are already worn ?? how did bearing look then ? also check little end journal in conrod for any defects in finish ,

ok how do you identyfy which is which is it down to frame numbers cylinder cc,s

can anyone tell me the differences in the 201 and a 301

it has a bend from memory so bends away from rear at spindle erea ,it must have a stop ( at fixing point ) so it doesnt pull up to swing arm , the spring can be a pain clearing the brake pedal fixing bolt could send pics via mobile if pm me your number

does anyone stock oversize pistons for ty mono or can a piston from a dt250 or it250 or simular be used as struggling to sauce an over size piston

that was worn out like ten years ago absolutely no grip offered by that ,it has also already been turned , the difference a new tyre would give would be like chalk and cheese , we in uk in wetter parts purely rely on the sharp square edge of the nobbles but also depends how good you are ,,,, also looks like you ride on hard terrain you might be better off with a dunlop the x light might be a bit soft and very flexible side wall which might suffer from damage easier if lots of hard use in dry rocky conditions

yes you can get pritty much all the amal parts try burlen ltd
