Hello purchased a rather snotty looking 77 ty250 last week up in Nova Scotia, Canada. Have started the tear down process and it has been coming apart amazing well. Have the motor and everything but the headstock off the frame as of now. Just the two bolts for the rear fender snapped into the frame. It seems to be all there parts wise, should clean-up well. Wondering on just the usual stuff that should be looked into that has proven to be problematic through the years? Suggestions for parts in Canada? Have found parts sites in Britain and France and in the States. Have removed the autolube for the oil tank sight glass was cracked Have cleaned the carb and flushed …

Hi al Got a TY175 recently and nice looking bike. Starts OK but will only run for a few minutes then bogs down after riding for a few minutes. When you let the clutch out when pulling away, doesn't want to go, bogs down and have to give it a lot of revs, but then eventually it dies and won't start again then. Any ideas? I think carb related as repalced spark plug and air filter is clean. Many thanks!

I am still having trouble with my kick start locking and not returning. Should the kick start shaft (and kick start lever) be able to move in and out by approx 1/2 inch. When the kick start does not return I need to tap it with my boot and knock it back into the cranck case a bit then it returns. Is this usual or am I missing a spacer?

Had a problem with my sons TY175 today. Was running great 'till a very wet New Years day trial, where is developed a bit of a cough and splutter. Airbox was soaked when I took it apart, so cleaned the airbox, replaced the filter with a new one (probably needed a change anyway) and cleaned the carb. Nothing obvious in the carb. Next trial out was today, where is had a distinct 'bog' off the bottom when opening the throttle. Also after stopping was really difficult to start. The 'bog' was so bad that riding through a section, seemed ok but then on the uphill exit, it just died (almost like you had left the fuel tap off). Decided to call it a day, again difficult to sta…

Anyone fitted one of those after market one piece fibreglass tank covers come seat for TY Monos? Curious about the quality, fit, durability etc. Any feedback appreciated. I have a Pinky with ugly stained plastic tank, hence the idea of improving the look as the tank cannot be cleaned up (so I'm told). Thanks guys.

Is there a way to make the TY175 clutch more progressive? I have the clutch extender and put in some heavier oil such that it drags until warmed up. Those two things helped but I'm wondering if there is anything else.

Hi Folks! having problems with my 250 majsety after doing a fun trial at earl shilton on sat night one of the sections involved a stretch of water (river!) which was quite deep in places! on the third time round the bike started to splutter and load up! after escaping the exit bank i made it to the van thinking the old girl had gulped a large amount of water (the villiers brigade merrily rode this section with the engines under water! ) anyway i removed the float bowl and removed any traces of water but the bike was still sick ie wouldn't rev properly or cleanly! anyway when i got home i removed the airfilter and checked inside the airfilter box all ok supprisinley d…

What do you guys think? Ever needed one on the trail? What kind of a problem did you have with the chain to begin with? I can't see even owning one for the shop much less taking it on the trail. Opinions/ experiences - please explain in detail.

hi my daughter was out on her little 80 today and it died it sounded like fuel starvation after about 30 mins we gave up when home i have checked everything carb is clean air filter new and genuine new plug reeds close flat against the block a very good spark compression but no running any ideas

I have a dead TY250a. It didnt want to play yesterday and today before a major trial today. I spent 1 1/2 hours before dark and 2 hours before the trial trying to get it to work. Fuel, yes: spark, sometimes strong or weak or nothing: air, new clean airfilter. I have checked and cleaned the points, checked the timing, new plug. Compression is good. Checked carby, all ok there. Any ideas? I've been advised that it could be: coil, condenser or maybe even crank seals. The bike has been a very reliable bike up til now, Ive serviced it every six months, just cleaned the points not replaced and they are ok. Oil get done every 12 months. I dont want it to become a shelf item j…

I'm after a set of 'Magicals' fork springs for my TY Pinky, but the website has been off for 'maintenance' for at least a month. Have they gone out of business, or can anyone offer a different explanation? Cheers, David

Hello , Would it be detrimental to remove the pump compleatly ? Thanks.

just picked up a 75 TY175. It has footrests that are bolted on the lower part of the frame.. below the kickstarter/CS sprocket. I see that there are kits to move them back, so I assume that was a factory option for these bikes? (I'm just starting to learn about these bikes so please bear with me). secondly, and more importantly, I see what look like a couple of different kits (or maybe they are all the same?) but wondering if I need to also replace the shifter/brake lever? I've ridden modern trials so I am used to the shifter being well forward of the left footrest, but wondering more about the brake lever.. it looks like the stock lever will require a bit of a s…

For those who might be interested, I've attached a couple of photo's of the footrest mounting brackets I made recently for my TY250 Twinshock. http://i253.photobucket.com/albums/hh79/mo...photos/0001.jpg http://i253.photobucket.com/albums/hh79/mo...photos/0002.jpg http://i253.photobucket.com/albums/hh79/mo...photos/0003.jpg http://i253.photobucket.com/albums/hh79/mo...photos/0004.jpg http://i253.photobucket.com/albums/hh79/mo...photos/0005.jpg http://i253.photobucket.com/albums/hh79/mo...photos/0006.jpg http://i253.photobucket.com/albums/hh79/mo...photos/0007.jpg They work out to be about 1 3/8" lower and the same further back than the standard mounting position. …

After some searching on Ebay and my local Yamaha bike shop (no help there) I am wondering about my next top end overhaul. I don't ride it much, but I noticed last time out that it was dinging a bit louder than I would like going down hill with the throttle closed. From what I am seeing, the time between overhauls on these 2 strokes is on the order of 30-40 hours! So I'm going to do a compression test as soon as I can fabricate a right angle adapter for my compression gauge hose. The hose I have with the compression gauge is too stiff to allow it to thread into the spark plug hole without risking damage because the frame is centered right above the spark plug hole. …

After some advise on new tyres, please. My bike had the original Michelins, but they're stuffed. Should I stick with Michelin? Any other brands worth considering (Pirelli, Dunlop, IRC...) or to be avoided? The bike is not for competition, purely recreational, but I still want it to ride right. Appreciate any words of wisdom. Thanks. bird bris. au.

Dear All, I know this has been discussed before but hoping for a few tips. I'm currently 'remanufacturing' a TY250E for mildly competitive fun use and have just spent a day stripping the forks. It all came apart reasonably well (half an hour with an air powered impact gun eventually removed the damper tube bolts). A bit of careful cutting of slots with a Dremmel got the oil drain screws out and deft use of a centre punch got the old oil seals out. So now I have a collection of parts which seem relatively unworn, but one damper tube was rusty so must have been sitting in water for a while. The stanchions are pitted and will be sent off for straightening /rechrom…
