I'm new to this '99 Cyclone with 14K miles, and I was surprised to see (presumed) engine oil leaking from the front of the shock. The bike runs fine and has had all the recall mods. It is an intermittent leak, and it is below where the oil pump is and on the remote reservoir. I drove it 1/4 mile and it was leaking about 10 drops as I slowly rolled it into the garage. Yesterday I couldn't get it to leak to track it down. Any suggestions?

AS you gradually loose oil the ride will become more harsh since you'll loose your rebound damping. Not so much the miles as the age of the bike, seals only last so long.

Measure the shock, eye to eye. If you've got about 14.5" you have the most current shock on these (this was probably done as you've had all you recalls completed). Check the classifieds here, then check ebay. Replacement shocks are out there.

You can use this as an opportunity to upgrade as well. Works Performance and Penske are both readily available. Works has a ebay store and will build you a discounted shock to order and send it directly to you. Still will set you back $650 or so for new aftermarket.

You can generally find new stock on the internet for $100+ so if money is an issue you have those options.

All 14.5 shocks will work, I may be wrong, but I understand the S3 replacement units have a heavier spring. Hopefully someone who knows for sure will chime in.

Oh, there are also those who've had their stock shock rebuilt by Racetech.

I couldn't find anyone of their local licensed guys who could do our particular type of shock so I had Aftershocks rebuild and custom valve mine, I don't think they're in business any more.

There are a couple other aftermarket shocks out there, I just can't remember who makes them at the moment.

If you are sure that it's the shock, buggles pretty much nailed it. BUT, I recently had the pleasure of oil leaking from the oil pump itself?##@!#$$%^&!

Mine had no leaks when motor was off. once started oil spewed out of the oil pump, all over the shock.

Since I just put in a new 14"er, I thought the new shock was shot till I got in closer to look at it.

Sometimes I hate to love these bikes.

To pinpoint the source, clean and de-grease that whole area of the bike, and spray on some talcum powder, or aerosol powder deodorant or foot powder. This will hold the oil right where it is coming from, and you will be sure if it is the shock or from ... the engine.

Oil has a slippery way of migrating from where it first appears, and thereby hiding its true origins.

Edgarr, Check the fitting on the front of the oil pump.

Thanks for all the replies. I did degrease and wash the affected area. It was leaking by the hose clamp that holds the reservoir up. I removed the clamp, and I haven't had a chance to get back to it. I'll know more next week.

It leaked about 5 drops very quickly after the bike was started, and then when I got my nose over to it it quit.
