thought it might be easier to pop a pic up the only thing I can come up with is it is chain wear as the adjuster is quite far in

Hey all been a while finally got around to sorting out the inlet valve on the SR knowing it had badly mushroomed and kept shearing the adjusters had a ball trying to get the old valve out had to grind it down so it would pass through the guide no major drama really just an hour with a small file popped in a new adjuster new valve seal and obviously new valve nicely lapped in flushed out the top end oil path ways didn't find much gunk and gave the top end a once over cams have no sign of wear neither do the rocker arms thought right time to follow the manual and put it back together again no major drama shocker for me I know lol now one thing im not overly sure of I lined up all the markers and reinstalled the cam chain about half a dozen times the closest I can get them all to been perfectly lined up is to with in half a cam chain link's length im just wondering if that would be an acceptable tolerance ? as there is no real guide in the manual I have thanks in advance

it might work the same ... worth a go at least i cleaned a bunch of carb parts / entire carb by poping them in to an air tight container and filling it with carb cleaner untill all the parts were covered just left them in there soaking for a few days gave it a shake a good shake drained it left it to dry out and then sprayed more carb cleaner through as a test on a spare carb it came out pretty clean no tacky residue left in at least the only thing really after that to be of concern is loose weld bits inside and allyoxide

clean what you can get to you might be able to get away with spraying carb cleaner up the overflow pipe a few times only issue is you will never know how much crud is actualy in there

This is the state of the intake valve the out isnt much better this is the intake adjuster screw which are the parts im replaceing

DOH that might help wouldnt it i just bought replacement adjustment screws as to me the ends of these look a little mashed they arived today so just installing them now was really just wondering if i should need to do any of the other parts but it looks to me like just the end of the adjusters have taken a pounding with there been too much clearance gap since its stripped ill take some pics and post them might be easier

Hey ya My SR 125 has developed a Top end rattle so i striped it down to check the clearance and found this to be out of tolerance by about 2.5 / 3 mm with the amount of play there was at TDC any way i loosened off the lock nut and took out the adjuster to find on closer inspection there appeared to be chips missing out of it and it been hammered out of shape no biggie Ive ordered some new ones any way for the time been i adjusted the clearance back to with in spec put the bike back together and it was running sweet as a nut so i know ive solved the problem but possibly not found the root cause of it at the moment i am assuming that over time they have just worked loose or just due to the nature of the pressures the parts would be under a consent hammering action this would be semi normal wear and tear exaggerated by the extra gap while they were out of adjustment but i am wondering if i should replace the valve end parts Cotters ect they look OK to me but been honest im more of a 2T person than a 4T well with regards to working on them at least is there anything else i should look for

Yep they are a dream to work on So easy lol

done 2 spaces left

re bleed the front break on saturday and cleaned out the caliper / seals polished up the piston it now feels like a break rather than a sponge also decided to remove the mesh behind the foam just to double check in side the air box glad i did as i found the original tool kit in there so much for the muppet that did the original PDI when it came out of the crate poor things had that cloging the air box for 16 years lol re tweaked the carbs to compnesate pulls 55/60 with my lard ass on it so cant be too bad passed the mot saturday morning with 1 minor fault ... slightly loose rear indicator nut

I bought some carbs of eBay for £25 The choke on those wouldn't stay out either so I used the one on the bike which did From what I could figure out if you take them off under the rubber grommet there looks to be a circlip it's probably that been worn that causes the issue

quite chuffed put the carb on last night and it ran sweet as a nut shocked that i didnt have to adjust anything will probably do a plug chop to make sure but touch wood after a couple of hours fettleing last night its about ready for the mot just want to re bleed the front as im not 100% happy with it as it is but its serviceable

i could like DR pepper ?

very true drewpy

i was thinking along the lines of using the 180 cylender and head at the moment its more of a half arsed i wonder if this would fit lol i dont really see why it wouldnt as i dont belive that engine had many revisions over the years as for more projects i really must get the RGV back in once piece lol

just as a random brain fart as im sourcing parts for the SR125 ive been working on does any one know of some one who has tried to do the SR180 conversion i can source a top end from the states but mostly wondering if it would fit at the moment my best guess is possibly could be fun for a future cafe racer project or similar yes i like insane projects !

hmm perhaps im to used to my Smokers but that seems about a reasonable amount of problems for that mileage hell some of the bikes ive had needed to have pistons / power valves replaced every 6 / 8 k intermitant electrical faults always will be a sod to sort out its probably a duff joint some where you least expect it or a sensor with a bit of crud stuck to it

thanks got one for £29 delivered so cant complain considering the unbranded or rather lesser branded ones i had been seeing were around £25 i want to put new innertubes on any way so i can fill them with a little slime that stuff can save you headackes at times lol Shouls be ready for an MoT after that

Hi ya cheers bud yeah single pot front which brings another question i wonder if the twin pot would fit lol ive found these Metzeler ME 22 3.00 - 17 RF TT 50P M/C for £30 delivered which i think is reasonable and more in keeping with the sound rear which is on there im just not sure what is meant by the RF / TT 50P part im assuming Rear / Front - Tubed Tyre - gawd knows lol

yes those bikes do seem quite hard to kill off lol

3.00x17 is out of the manual / what i can source from online mainly as the bike is 30 miles from home at a friends house so im trying to get as much of the parts together in little hits and blast out the work when i get to his for some reason it seems easier to find metric rear's than the front

Hi ya a Brief intro i picked up a SR125 which had been stood for 11/12 years judging by the currant mileage / last tax disk and started giving it some love and attention it would run literally just about so striped the carbs replaced most of the O rings pilot jet , main jet , spent a couple of hours removing and polishing all of the rubbish out of it Now looks like new at least on the inside where it matters lol Replaced fuel lines . new filters Replaced the filters air , oil Fresh oil Fresh fuel after cleaning the tank out Fresh air Fresh break fluid / braded hose Checked clutch / disks / rear shoes all with in tolerances Re greased all points / cables C/S look good after a clean in 10/40W at least good enough for a few miles Rear is a Meltzer seems in good nic and looks fairly recent no crazing or for that matter run in !! Front tyre is toast way to crazed for my liking so need a replacement And that’s where I’m stuck I hate running mismatched rubbers and ideally prefer to stay with something similar to the Meltzer on the back Wondered if anyone had an idea where to look front rim seems to be 3.00 x 17 from what I can make out Looking around at a few rim / tyre conversion charts it may be possible to get a 100/90/17 on there ? if any one has some ideas id apreciate it

Just thought i would say hello picked up a Sr125 a few weeks ago and started giving it some love and attention 11 years standing have not been nice to the carbs or the rubber for that matter lol
