TY175: Engine Strip & Clean

Here's a few images of the engine strip down.

 

 

 I had all the ally aqua blasted. It never ceases to amaze how well aqua blasting cleans cases.

 

 

 Here are the seals and bearings ready to go back in.

 

TY175 - Exhaust Update

Since my last post on the exhaust I bought a Soda Blaster from Millar Soda Blasting and what a great bit of kit that is. The media is expensive (particularly when you add P&P), but it works a treat. I blasted the main part and the tail pipe, and sprayed them with Hycote Barbeque Paint. I've had the exhaust guard painted, and with a genuine Yamaha fitting kit, these is the Before & After results:

TY175: Throttle Body / Kill Switch

So I settled on the TY250 style of switch gear withe the kill switch incorporated into the throttle body, rather than the separate kill switch (see here).

This is what I started with:

This is it stripped and cleaned:

And finally back together again:

TY175: Airbox Update.

Here's the airbox as removed from the TY.

I've stripped it down, blasted and painted it with Hycote Barbeque Paint. I found a better flexible connector, and all new Yamaha fixings, inc new 'jubilee' clips. I heat shrank some black tubing on the arm that clips over the frame, added a NOS filter and mounted it all up.

Overall I was very pleased with the way this went.

TY175: Levers and Throttle - Update

Following on from the previous post on levers and throttle, I've finally got a replacement perch for the damaged one (Thanks Tom).

So, I now have a complete set of controls.....

.... except I don't. I'd been think about how or what was used originally for the horn and kill switch. I believe the switch above is TY175, but have realised that the TY250 has the same switch, but incorporating a horn button. So, I have this to refurbish and use instead:

As for the engine kill button - it seems I'll also need a TY250 part. Found (but not bought) this throttle with kill switch on eBay ($200 !):

It looks a neater solution than the seperate 'afterthought' kill switch. Mine shown below

And a different TY250 option below.

I'll see what comes my way first.

TY175: Rear Mudguard

This was a bit of a battle. I started with a new pattern rear guard, a NOS Yamaha inner metal guard, and all brand new Yamaha NOS fixings, grommets, etc.

So I offerd it all up, and with a lot of pushing, pulling and swearing, I managed to get all the fixings in, but, the mudguard was kinked, and under a lot of stress.... So, scratch head, and back to workbench.

As the inner guard was genuine Yamaha, I figured that would be the best alignment of the mounting holes. But, against my frame, the rear hole needed a little elongation to fit. You can just see it below.

I then had to elongate the three holes in the plastic guard to match the 3 mounts on the inner guard. Once this was done, it all mounted up OK. I had to add a washer to the rearmost mount, on the visible top of the plastic guard to hide the elongated hole, but it's not noticeable.

Below are some general shots of where the build is at.

TY175: Rear Light

I bought a pattern rear light from eBay, thinking that was a clever move. It turned out to be OK quality but not the same as the original Yamaha part. See below, the extra mounting hole at the rear of the new light on the left.....

So, I refurbished the existing light on the right. The only part used from the pattern light was the chrome strip, as the original one is scratched, and dented.

The original light cleaned up OK, I used some new grey cable sheathing, and added new terminals. It turned out pretty well, certainly far better than the pattern one.
