Hi All

I have a TY 250 Mono that has matching frame and engine numbers ie 59N00166 which I believe makes it a 1985 N model ?

Two questions:-

1. The head and carb inlet are stamped 38V..Does this mean they are from a different model?

2.The rear shocker looks like it has been set to its highest position making the suspension quite hard. I assume to adjust it there is a C spanner required? not having one or wanting to but one how else can I adjust??

Thanks in anticipation

Regards

Maybe you could either remove rear shocker,and put in a vice,or try and tap the locking ring with a blunt screwdriver,or a large pr of adjustables.As you say the 59n relates to a 85 model.

Anything you do to adjust that shock without the proper tool is going to be difficult, bugger up the adjuster, or both.

What you're saying is, "I have all these phillips screws on my bike, but I don't want to buy a phillips screwdriver....any suggestions?"

If you don't mind following in the burr covered, metal shard encrusted footsteps of the hammer-and-tongs men of the past, just put a screwdriver in the slots and hit it with a hammer; or better....a rock.

The 38v just relates to part number. Yamaha does not change the castings when the same part is used.

Thanks to bilks and lineaway for your sensible answers....As for charlie chitlins...i'm not sure what you are implying here...The reason I asked the question re the shock absorber is because I am not a motorcycle mechanic with a fully loaded workshop full of specialist tools...If you are then you then you are lucky!.

I would guess most of the guys on this forum don't have access to specialist tools and will post a question to ask how to overcome a problem such as I did.

If you cannot answer a question with a sensbile answer then don't bother!!!!!

By the way I managed to adjust the shocker by putting it in a vice and gently, with a pair of steelsons, moving the adjust round WITHOUT burring any edges and WITHOUT a rock as you suggested..

Cheers.

Most folks would prefer to adjust the shock while it's on the machine in order to fine-tune the results.

If you got it right first time out, you might have mechanical skills that warrant a better tool kit!

And...FYI...I have been a professional mechanic and have a pretty well outfitted shop.

OTOH, I am a terrible cheapskate and, by no means, a tool collector.

I have a bare minimum of tools and only buy a tool when absolutely necessary...or if I can't make it myself.

Even I have a couple ring spanners.
