I braved the cold shed after w.o.r.k today and cleaned out the carby; not bad, but a few gremlins in the bottom of the float bowl. cleaned out petrol tap filter, drained the 'running in premix' and put in some fresh 50:1 fully synth and super petrol.
ran the same, but when choke pulled out, no more dongk dongk dongk on closed throttle over run - so it is weak!
raised need to clip 5 - no difference, so it must be needing a bigger pilot - all the jetting is bog standard by the way.
the next size up pilot is 27.5 (std is 25) - should that be enough?
well, my rattly old ty is not rattly anymore, having been rebuilt with a relined cylinder, wossner piston, new rod, big end and mains etc.
the timing is spot on.
the jetting is less spot on (work in progress)
not sure if this is a new thing, or if the bike always did it - but didnt notice because of the bad rattles it made before - but on over run, it makes a sort of 'dongk, dongk, dongk' noise .................. I have read about the 'pipe bang' problem (on usa sites mainly).
is this normal for a ty?
pjme did all the machine work and the bike was put together properly - otherwise its all fine.
Today I did the "clutch fix " to my sons JTR125 , Spent a few hours filing off burrs and scraping glue off the friction plates, put in new ATF and wow, we now have a clutch that works properly. I rode it round in the garden to warm it up, I was able to find neutral easily. First time the clutch has worked properly since we got the bike about 4 years ago.
I did replace all the plates once but fitted them in a rush and the clutch has never freed off as it should.

you must have the patience of a saint to do that mod! hats off to you.
yes. when I got mine I took it apart and greased the linkage/steering/wheel bearings etc, changed the gearbox oil from atf to castrol power 1 10w 30, changed the coolant, changed the brake and clutch fluid and fitted the hour meter and new c+s. the only fails have been the seal in the clutch master cylinder (easy fix) and a broken kickstart lever as I binned it on a stretch of unfinished civil engineering works (don't ask!!)
I bought my 2005 250 pro for about £1500 (I think) a year and a bit ago. it was low use and on the same piston as far as I could tell. I fitted an hour meter and have since done 80 odd hours on it and it sounds the same, and performs the same as when I got it..... bags of compression too. I am used to high maintenance enduro bikes, so the gasser is relatively bombproof in comparison. I change the gearbox oil every 10 hrs and run it on 50:1 premix with castrol power 1 fully synth 2t oil. the air filter - which i still find a p.i.t.a to change - is kept spotless and oiled with putoline filter oil. I asked a similar Q to yours on this forum and I think that the general advice was just ride it. its been a good bike - my advice to you is, if you get it, is to take it apart and grease all the chassis bearings.
Hey ship you might want to try getting this one in too .... slower than a Mexican village......Sorry any Mexicans reading this .
far too un-p.c to get in a conversation! .............. 'about as useful as an ashtray on a motorbike' raises enough eyebrows in a typical daytime scenario for me ;-]
when i first had my gas gas i was worried about the play you describe; ripped it all down and cleaned and repacked bearings ....... still play - phoned up gas gas uk and spoke to a techie '' they all have that play'' was his response ............... so, a year later and a further grease with the stuff posted above and all is good.
the rear shocks are betor's and look fairly new. with the amount I have had to spend on the motor, I am keen to use the existing shocks.
trouble is, despite softening off thge spring setting, they are very firm - can you let some of the gas out of the valve to soften them up?
front forks are standard with new chrome inserts and seals (previous owner did this) they are firm too and only go half way down if you load it ............. to soften, do i just use less oil / different oil?
thanks
Andrew
p.s pjme did a top job on my engine bits (cylinder reline and crank work)
Hey ship it's actually colder here than it was in the North North Sea, although the reverse vertical snow we got had to be seen to be believed ( the wind was so hard it was blowing it back up to the sky). Every where is flooded to hell but in Dumbarton today it was sunny!Still colder than a witches tit though.
Today, I will be getting ''colder than a witches tit'' into as many conversations as possible! - brilliant.
Ted - what a great bike! you must be over the moon. Hopefully you will be tearing it down to do a grease job ............ I do this to every bike, even the new ones; factories don't grease stuff up anymore (my new enduro bike had zilch grease anywhere [i use the marine grade stuff]) Oh yeah, dont forget to zip tie the rear fender ;-] I would think about putting an hr meter on the bike as its new ................... then you can keep an eye on the maintenance (under £10 on eblag)
Hey you two do you know that the U.K is getting an upgraded status on the weather front ! The rainy seasons been made even longer !
Wish we still needed to make a wood fire ,it's the one thing i miss every day ,getting up chopping and making a fire. Input equals reward .
Jimmy, Zippy - dont Let Shyted lead you into thinking that its that warm here ................ I am still having a fire in the evening! ...............
Cool! How'd you do, Andrew? I would imagiine there were no problems with mud stopping the front wheel now? Godd idea on that, btw.
Jimmie
Hi Jimmie - the conditions at this trial were much kinder than the last trial; the last trial was in an old quarry that was in a very clayey and chalkey area, whereas todays trial was 100 miles north and in a sandy forest with only odd patches of clay. I think that I probably only dropped half the amount of points that I did a year ago - that was the main objective .................. to see an improvement! it was getting quite a bit colder in the afternoon though, so everyones bikes were running that little bit weaker and needing a quick tweek on the fuel or air screw. By the next trial, I will be out on my TY 175 (with a rebuilt motor and new bearings in the chassis [but a scabby frame and a dented tank .................])
Today, my gas gas and I did our first trial of the year and its a year to the day since I did my first ever trial - I think that I am slowly getting better.
Ty 175 Knock On Decel?
