My TY250 restoration

I finished my ty resto , so here are all the pics of each step (or at the least the ones i took pics of).

Here it is how i got it , somebody had done everything in black, it was all wrong.

Image

here it is geting striped down....


Image
Image
Image
Image

next i sent the frame to the sandblasters, all the paint striped off it, then redid the frame in two pack silver, as close as i could get it to the original colour, going off old photos

Image
Image

next step was the engine. as anyone whos ever riden at menai will know,menai mud stains! so everything was striped down, paint stiped, etc.

Image

The engine ran fine,but after pulling it apart, we found the bore was glazed, so i had it rebored,and a larger piston with new rings fited.

Image
Image

All of the side covers on the motor were damaged and scratched deeply, i saved most lettering apart from I think the word "magnesium" on one cover.
All were refinished in two pack silver,matched off the original parts.

Image
Image
Image
Image
Image
Image

next i detailed the cylinder after geting it back from the machinist. redoing it in black,with the edges showing the aloy still..

Image

Image

Image

And heres the motor all back together, the gear box was in perfect condition, so it was left as is.

Image

Engine bolted back on the frame,

Image

Next i sent the front forks to the bike mechanics to be rebuilt,and ordered some new parts from japan, while i was waiting for all that , i got to work on repairing and painting all the cosmetic trims..

Image
Image
Image
Image
Image

The seat was in excelent original condition, so it was redone with vinal black paint..

Image

Ok forks back from the mechanic here, and steering head fited with new style needle roller bearings, new brake and clutch levers.
the rear shocks are the original items, just polsihed and cleaned back up, they still seem to be ok.

Image

handle bars are renthals,and were gold,but i have sanded off all the gold and polsihed them up so they look like ty items.

Image

Now for the fuel tank.
It had a rather large dent in one side, so first off i made up a paper template of how the yellow and white was,and where the stickers should be.
next i paint striped it back to metal,or aluminium, and worked out the dents as best i could with levers through the filler hole,and then finished them off with body filler.

Image

heres the tank in two pack hi-fill primer

Image

After blocking down the hi -fill,i painted the tank all yellow,using colour i had matched up before i striped it back, let the yellow dry,then useing my template, marked out with fine line masking tape where the white should be.
after painting the white,and removing all the tape, i folowed the line with black pinstripe,and then placed the yamaha stickers where they should be....Then sealed the lot with two coats of two pack clear.

Image

Next the exhaust was sandblasted and powder coated, a pic of it here trial fitted..

Image

Coming together now, just waiting on the accelorator cable to turn up from japan, so i can fit the carby,air box and all the freshly painted bits waiting for it....

Image
Image

Well, finaly after 3 weeks the cable arived, and within an hour the bike was back together!

Image
Image
Image
Image
Image



The bike fired up on the second kick on a cold night here,and runs like a dream.
Theres a lot of other new bits i forgot to mention ,like swing arm bushes,brake shoes,cables etc ..but you get the idea im sure.



A big thanks to local forum ty guru David lahey for all his help and information on how an original TY should look!

Nice resto job, gone to quite an effort.
Where did the steering head bearing bits come from?

Hope you actually intend to ride this bike again, as it wil get scratched you know. There are a few that do this then want to sell their bike on E-Bay for a squillion. hope you intend keeping it for what it its intended for, not parked in a shed for collecting.

My TY looks sadly rough, and being ridden it will always be the case, hence why the point of me posting a pic. I intend to keep riding it, but maintained - the difference to the other roughies. After I get through with my intended mods, I may give it a birthday too!

Thanks subanator.

The bike will definately get riden!

We have had wild weather here for the last few days, i was suposed to be up at pacific park on it today, but with all the rain, i didnt get a chance to run the motor in around my workshop car park before i took it to the park.

of corse i dont want to scratch it, but i just dont want to cake it in mud, so ill be sticking to the rocky stuff rather than the dirt and muddy areas.

Nice work Dave! :)

Bikes are much easier - and cheaper - than cars, hey!
