Gear shift fork damage?

[matthewmosse]

I've got better forks in a 200,000 engine and worse out of similarly low milage engines, I geuss it goes to show its all down to how the bike was ridden and looked after. If thrashed when first ridden rather than being run in before being ridden a bit gently then the wear on the thrashed bike is going to be worse even if the milage is lower. That is assuming the milage on the clocks is genuine, my 500/4 is showing 60k, but thats been round the clocks at least once and had a good used set of clocks fitted after the originals fell appart internally, not to mention a few months at a time commuting with no speedo cable - using the same route means you can tell the speed off the sound of the engine close enough.

At a guess 90+% of the "Low mileage" bikes imported from the U.S. have been "clocked", real mileage may be 3 or 4 times that. There was a discussion about this kind of import over the last couple of weeks.

Wrong oil or riding with foot on lever as I think that is the most used fork. Price depends on condition and postage will look for gear but remind me which one

[sgd37]

It's number 12 in this

You will probably have to fit the gear it mates to as well to be  certain as the tooth profile changes at some point on that gear, I will have to check on what I have

[sgd37]

I just ordered a NOS one. Are you saying I have to order the other one too because they need to wear in together?

[sgd37]

Damn those look tempting but I really can't afford it at the moment. Maybe on the next rebuild. Cheers for the resource though.

[Bryanj]

Its not that they wear together, the part number changes at an engine number and i suspect Honda changed the profile(shape) of the tooth.

When it arrives fit it and see if it turns smoothly when in mesh, if so you should be OK

[Bryanj]

I know that the replacement for one of the other gears is sold as a mating pair due to tooth profile and wondered if it was the same with this one. I forget how i found out but i think i needed one and wherever i got it from, probably a US dealer, sent me a copy of a bulletin letter but i lost it now. Just sticks in the brain, or whats left, without all the info as usual.

[sgd37]

Well I got the gear today. Seems to mesh pretty well.

I had another look at the gear the fork sat on and it seems to have left some metal on the sides and the surface seems polished.

Is this one crodged as well?

Put it this way, i wouldn't waste a new selector on it!

[sgd37]

Hmm this tranny is full of good news.

In that case would you mind seeing if you have a better looking one to go along with a fork.

Many thanks

I will have a look in my lockup this weekend when I look for the tacho for another member

[sgd37]

Awesome!
