I've got an issue.

[Beehive Bedlam]

In September the 13th my Varadero, failed me and left me stranded at 05.30 in Wakefield on the way to work.

The sprocket shaft what front sprocket connects to failed I wheeled it to a nearby garage and he told me the bad news and gave me two options.

1) Buy new Engine from ebay.

2) He would weld it on but no guarantees so I won't be able to take him to court in case it fails. (his mate who doesn't work there did it using the garages tools).

I went with the latter so off I went to get a new front sprocket to be welded on for the cost of £30.

It has been fine so far covering 38 miles to Silsden and back every day in torrential rain and flooded roads even cars wouldn't drive through.

Within the last three weeks I noticed when I hold the clutch in and roll I can feel a very light click is this due to the weld? I have cleaned and lubed the chain often there has been no oil leaks. The chain is at the correct tension.

I've put on nearly six thousand miles since I purchased it and added no damage and have complete ten year history so could easily get back £1200 I paid.

Should I sell and get another or will it be able to be grind off as the mechanic suggested?

You have to weld front sprockets on?

They welded a sprocket to a shaft? How the hell did they align it anywhere near to acceptable mechanical tolerances?

Engine shaft the bit the front sprocket slots on knackered lost a tooth could be worse I don't know.

He gave me the old sprocket back and said I will need to keep it for the back plate.

wakefield to silsden on a 125 every day ! jees

Sprockets and output shafts are usually made form high-carbon steel so it can be heat-treated and drawn to a suitable hardness so the bits don't wear out. Welding either will upset this heat treatment and might well lead to a failiure of the weld, or even the shaft. I have seen probably a handful of welded-on sprockets on various machines and most have either a cracked weld or evidence of re-welding (obviously following a craked weld). It's very likely that they could be welded but using a specific procedure and using pre- or post-weld treatment - I don't know, I'm not a welder - but in my opinion the odds are on that it will crack at the weld sooner or later.

If the 'damage' was just a retaining clip groove or something it would be far better to put the sprocket loose onto the shaft and then put a blob of weld on the shaft to stop it slipping off. If the shaft spline is shot so that the sprocket can spin on the shaft, then welding is about your only option unless you want to strip or replace the engine.

Here is the welded sprocket.

Shall I sell the bike now and save myself the headache of having no transport?

Or can it be grinded off and a new one welded on when the time comes?

If you sell it, are you going to tell the potential buyers about this fine example of mechanical ineptitude?

[Alice-In-Sunderland]

Should be fine and dandy, leave as is.

[woo]

so when you need to take off the front sprocket due to needing a new one how is that done?

You can start a new account, Jive, but karma still catches up with you. Wrecking your Daewoo was bad enough, but someone could have had use out of that Varadero.

Sell it, ride your R6.
