    I struggle to start my sisters ty80 from cold it takes about 15 min to start. Once started it will start from hot really easly (even my little sister can start it). after it has warmed up it starts to rev realy high (about 20 min after start) so i have to run for my screwdriver and adjust the carb. I have recentley changed the coil and cleaned out the carb but this does not help much more. Once the bike is running every thing is fine but i just cannot work out why it stuggles to start from cold it cant be because it is not started that often as the bike is reguarly used and if not used weekley it is normaly started just to warm it up. Does anyone know what the poblem m…

    I am looking at a ty175 for my boy. The bike seems to run ok but the shifter shaft has alot of side to side movement. How big of a deal is this? Is it an easy fix? Is this a common problem with ty175's?

    I have just stripped my TY 175 engine down so I can change the damaged crank case and on cleaning the carbon of the top of the piston I noticed it has 125 stamped on the top. I bought the bike as a box of bits which the previous owner had dismantled. The frame and engine numbers don't match so I am wondering if a 125 head and piston have been fitted at some time or dose the 125 stand for something else. The good thing is that the piston and cylinder are in tip top condition. Can anyone shed any light on this?? Iain

    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 can anyone tell me if the swinging arm on my w/hawk should be fitted with dust seals on the end of the bush ? also should it be fitted with a nylon buffer around the s/arm to stop the chain from eating into the metal? it is also cutting into the cross member above the chain so should it have one of those chain rollers fitted or is the chain just to loose? (although i dont consider it to be)hope someone can help as i enjoy riding it but my local m/cycle shops cannot tell me because its not the standard frame. thanks for your help and time Sam

  18. Hey, just stripped my front Talon disc brake down, and the diaphragm is too swollen to get back in. It's a Brembo brake lever, and the Diaphragm is a Brembo 10 271140 (The 10 is also offset upwardsso I don't know if this is relevant to the part number or not). I can't find one anywhere online. Haven't rung round locally yet but just wondering if someone on here has ever had to find one and if so, where could I get one from? Cheers.

    Dear all, can anyone give me a definitive answer as to what engine parts are the same, if any, between a TY175 (engine number is 525-2***** which is 1977 on) and a DT175 of approximately the same year? I need to strip my engine (it's burning the gearbox oil and so running like a dog) and I have been told by a couple of 'experts' that the 2 engines are identical but how can they be as they are intended for different uses? I accept some parts may be the same to keep production costs down but I don't want to buy any parts in the hope they may be the same. Also, who in England are the best people to deal with for TY parts? I don't necessarily mean the cheapest but the best qu…

    Requesting an opinion here: Rode a Trial today. Several creek/river sections with the water probably 12 to 14" deep, also raining cats and dogs. Not in a sections but on the trail between, the bike started to run rough and finally quit (it has never done this before). Had to restart/ride a bit, restart/ride a bit then it cleared up. Ran fine for the rest of the Trial. Did I suck water into the air cleaner/carb or did I get the point wet? Well or any other suggestion you might have. Would like to solve this prior to the next Trial. Alan
