Are there any new type(wider) footpegs to fit a '74 TY250? Or would DT250 footpegs fit?

Anybody have the chain fall off and break the rear case boss that the mag cover screws onto? Am I better off cutting off that lug on the left center case before that happens ? Or is a case saver plate the way to go? Thanks, Jeff

Hi, I've just purchased a TY250Z (water cooled mono) that needs some TLC before being ready to trial. One of the issues is that once changed up to 3rd or 4th gear I have problems changing down, it requires a lot of force/persistance. The lever moves down freely but there is no feeling of it changing gear, it just moves to a stop & springs back when pressure is released. Anyone seen this before/knows what the fix might be? I'm also having trouble finding a service manual to download, anyone know where I might find it? Thanks Phil

Hello Again. I've already asked about the Rayer kit. Now has anybody used the 200 kit upgrade? From Trail and Trial? From a standard 125 how much tinkering would be needed to make this upgrade run smooth? Cheers Squid.

I am in the middle of assembling crankcase halves for my TY 175. Because the guy who owned it before me only used one dowel when he re-assembled the crankcase last time, I did not realize (until just now) that a needed two of the things for the upper and lower mounting points. I noticed when I was trial fitting the dowel to the lower mount that it fit snugly and would seem to do a good job of reducing vibration. However on the upper mount, it was so loose as to be apparently useless. Are there two sizes of dowels? Are there two sizes of O-Rings??

Hi all, My brother in Australia just purchased a TY with 125 stickers on it. Frame number 5890047-- and engine number is just 589, nothing following. Bore is 66mm so guessing it's a 175 bore. . I have searched the id tables but can't find a model 589. Anyone any ideas what year this may be? And should it be a 125? Thanks!!

Hi I thought I would share my recent experience of removing the front 2 cylinder nuts (long aluminmium) from my TY250D. These nuts were seized solid I tried the following methods to remove them because I thought they were seized on the crank case studs: 1) Impact wrench (24v electric) - Did not budge. 2) Long extension bar and 13mm socket with a blow torch heating up the nuts - Resulted in rounding the hex shape of the nuts. 3) Drill a small hole in the top and spray liquid wrench onto the stud inside the nut, then use a irwin bolt extractor with a long extension bar - resulted in the hex section of the nut shearing off completely. At this point I was considering …

Hello can anybody tell me if the main engine casings from a 1974 ty250 will match up to a 1978 motor. The left main casing on mine has been attacked by some eejit and is full of holes around the magneto. All I can find are listed as 1974 models. Would like to keep the numbers matching! Thanks in advance Jaybee

Hi All, I have been picking up useful information from the forum for years but this is my first post. I bought a rough looking bike on Ebay a few years ago knowing that there was a majesty under all the alterations and rust. I took the head of to check if the bike was a 250 or a 320, the bore measurement was 70mm so i assumed that it was a 250. On further investigation the left side crankcase was broken so i managed to find a new replacement on Ebay. Yesterday was the first time i have been able to put the old and new crankcases together, and i noticed the opening on the old case for the cylinder sleeve is larger than the new case. Am i right in thinking that th…

Any answers/ suggestions are appreciated. I'm knee deep in a 1977 TY-250 build and I'm wondering ... Has anyone decided to remove the factory head and tail/stop light? The bike will never be road legal and I don't plan on taking it out at night so I'm thinking I remove the lighting coil from behind the flywheel and delete the other bulbs and harness. Any thoughts or tips?

How do you remove the seal under the bolt at the bottom of the fork? Do you need to replace if it looks OK? I currently have 2 sets of forks. One set has what looks like a red fiber washers in place but they do not want to move almost like they are glued on place. I don't know if both sides sealed or not. The second set looks like it has copper washers on top of the red fiber washers. Both sides of this did seal.

I have 1 360mm on my Yamaha TY 250 that has seized about half way on the stroke. It will compress but will not rebound. I will be rebuilding both shocks but cant seam to find the oil volume does anyone know how much volume that they hold. Cheers

I've bought a TY250 Mono. I took the engine out to paint it, but now the clutch lever arm is not pushing the pushrod to activate the clutch. I can remove the lever arm and see its a cam profile. There is marking where it pushes the rod and it's not excessively worn. My mechanical knowledge and ability is far behind many of you on here, so I'd appreciate some advice on how to sort this. Thanks Dave
