    Hey everyone! I've been riding my dad's old 78 ty 175 up at the annual "bike weekends" at the cottage when my family and friends go up to do some hard riding.. (there are probably 20 people that go, family and friends.. being 18, they figure I'm old enough to ride with them) Now I didn't keep the bike to it's original silver colour all over, I wanted to paint some accessories gloss black to make them stand out and make it unique to my likings.. so don't flame be about not keeping it original I plan on owning this bike forever haha Anyways, it took about 2 months for me to finish, and my friend took pics of my progess the entire time.. there are over 100 mb of high qu…

    It would appear that my previous post of the same title was removed becasue I placed a link to an ebay auction which is against the rules of the forum. However this was not my ebay auction and I was only posting the link in order to show the colourway of the bike to try and establish the year and any other associated details of the bike. So instead, I've placed the picture instead (please note this is not my bike, but is an accurate representation of how it looks...albeit considerably cleaner). Many thanks for all of your previous comments and help. Maybe I should rstore it myself as a project?

    Hi all. Has anyone fitted Boyesen reeds on their TY175? If so did it make much difference and what difference (bottom end, top end etc.)? Did you have to change anything else (jetting?)? I know guys with moto X bikes that reckon these are a must have. Cheers.

    Hello, I'm new to this and I posted this in the wrong place, so i'll try again. I have just bought an'85 TY250 mono and when the engine is warm either on overrun or light load, you know how they only fire or pop erratically well each time it "pops" there is a loud metallic knock. Is this normal because I thought something was going to let go! Any help would be much appreciated, thanks Mike.

    I have a '74 TY250 and it seems like the back end is a bit skittish. I saw someone had posted in one of the forums about modifying the rear suspension to match the dimensions of a Honda TLR200. I checked the measurements and it looks like the swingarm on the TLR is about 1.56 to 2 inches longer that the TY. I have seen a set of weld on extensions for the TY250 on eBay. Anyone have any inputs on this? Anyone extended theirs? How did it work out? Note, I am in the USA so no problems with scrutineers. The TY250 is mostly a buddy bike and occasional play bike, not a serious competition machine. Thanks.

    I have recently removed the flywheel weight from my TY250 Twinshock and went out on it this morning to try it out. What a difference! Much more responsive. It pulls right off the bottom of zero revs and I can now ride a section that requires 2nd gear somewhere in the section and ride the whole section in second, without having to think about changing up. This is where it is most noticeable as it will now pull second instead of dying if I'm not revving it enough, as before. Also I've had to turn the tickover screw out 1/2 a turn now the engines not dragging the extra weight around. The weight (and bolts) weighed 750 grams. The flywheel now weighs 1650 grams with it r…

    Hi everyone. I just picked up what I believe to be a 1979 Yamaha TY250. The VIN numbers on the frame and engine are the same: 493-100302. Does anyone have a picture of a complete bike? I am having no trouble finding parts and information for the 74 but the 79 I can't find much information at all. Wondering what the seat/fender setup is supposed to look like. Also it has a 21" front tire. Is this correct? I am going to restore it back to factory specs. Thanks in advance for any help. Here is a picture.

  13. Just took my heavily modified 78 175 out for its maiden run yesterday. Thrilled with how it runs and performs now but the chassis performance has gone all wrong. Hoping to get a new gameplan to make it work like it should. Steering has become incredibly heavy and floppy from side to side. I've lengthened the swingarm as per standard 1.5 inches +/-, lowered and moved rearward the pegs and moved top shock mounts forward about 2", running 13.4" betors. These mods are proven successful by many others already. Where it goes wrong is in the forks and if I hadn't already given away the wimpy (but working geometry wise) standard forks, I'd just put it back to stock... The f…

    I have trawled about 13 pages to find info but no joy. Which is the best kit available to reposition TY 250 twin shock pegs. I know Millers do a bolt on kit, are there any better ones available, it seems good value but the kid on the phone was not too sure whether it lowered them by much. PS its a Yam framed Majesty.

    Goudrons and Charlyxty were kind enough to offer assistance with my electrical questions for my recent TY80 purchase. I stripped the side cases off the motor tonight and now have more engine related questions I am hoping someone can answer: 1: Can the gear shift shaft be replaced without splitting the cases? it looks like it just pulls right through from the clutch side (I hope so, the previous owner sheared the splnes off the end of the shaft with vise grips) 2: when I pulled the clutch case I noticed that one of the basket side pieces is snapped off. I will look for a replacement but if Ican;t get one will it still work okay? when I bought the bike the engine was out …

    Guys, So after getting my parts back from Millenium Technologies- new bore on Ebay cylinder and new piston- I noticed quite a bit of vibration. So today I tore it down again and weighed the new piston, pin, upper end bearing and compared those weights to the ones on the original parts. As I expected, the new piston was significantly heavier than the old original piston, even though the piston size was still the same. Old Piston 213 gm New piston 241gm a delta of 28 grams. Old pin 57 gm New pin 60 gm delta of 3 grams The remainder of the parts were too light to measure on the scales I borrowed, so I am forced to ignore those …

    Hi all, does anyone know of any sensible mods to liven up a standard TY175? I'd like to make it respond a little more like modern bikes. Maybe take some meat off the face of the flywheel (how much?) and I know the porting can be altered but don't know the specifics... and I'd hate to end up with a useless barrell! Thanks in anticipation Mark, Perth Australia

    I am in the process of preparing a Yam Ty 175 Yam and turning it into a 200 Majesty ( am I right to say Mick Andrews John Edward Shirt T.Y. is how Majesty came about?) So if any of you decent people out there have any info on frames, turning 175cc into 200cc, shockers, the history of the marque, how to squeeze that extra power from the engine, length and placement of shockers subject to rider weight, forks, exhausting matters, and any info on this bike, however insignificant you may feel it is, please post it here, your reward will be several pints of the finest beer known to man. BODDINGTONS: the cream of Manchester as well you know! Thankyou. Eiger.
