How tough a job is it to swap an engine?

I've got limited time to sell a bike that needs a new engine, and debating whether to invest ~$700 to buy one and try to get the bike running.

It seems like I could knock that out in a day or two in the shop. Any hurdles I should know about? How often do people have problems with ebay engines?

I can do one in a day. However, there are always special tools you need. Suzuki has castle nuts that need a special socket.

Ebay motors? Everything from good to horrible.

eBay engines can be a crapshoot.

Last one I dealt with was a mess and required a lot of repair.

The previous several were fine and worked great.

For me, swapping and engine is an easy day and on some bikes only a few hours.

I have seen a professional mechanic swap engines in 45 minutes. But that was someone that did it all the time and with intimate knowledge of the particulars.

The best performance upgrade is upgrading the operating system of the operator. It is cheap, easy, fast, safe and works on every bike you will ever ride.

Another option is a motorcycle wrecking yard that will sometimes warrantee and engine to at least be functional when installed. No matter who or where you by from, make that a condition of the sale. No one is going to give you a 6 month warrantee, but you should be able to negotiate a sound motor when installed.

That's a thought. Are there any moto salvage places in the Bay other than Hayward Cycle Salvage?

special castle shaped drivers can be fabricated from a walmart cheap set of spark plug sockets and clever use of an angle grinder

take lots of pix, use tape for numbered tabs on various wires and hoses

Or they can be bought on Ebay for $14 and actually work.

According to the FZ6 forum peeps, no weirdo tools required for this one. Engine should be here next week. Wish me luck.

I’ve done it a few times and as long as you keep track of what goes where, you should be OK. I like to use paint pens and tape to mark every hose and harness and take lots of pics along the way. Also make sure to have the service manual on hand for torque specs and schematics...

Also, It really helps to have another person as a helping hand. When it’s time to drop the motor and raising the new one in, a second pair of hands and eyes really helps out...

I just did a Gixxer 600 motor for a friend last week for the cost of pizza and beer! Start to finish was about 6 hrs...

Yep, good advice.
Take pictures with you phone of wiring routing, connectors, what goes where etc. Ziploc bags and a marker will help the process going back together massively smoother.

Seems relatively straightforward. Anything I should check on the engine before mounting? I was planning on adjusting the valves and checking the timing chain and CCT, since that's all way easier without having to fight the frame.

Do you turn it over with no spark a few times to get oil/coolant distributed?

Well, shit. Got the engine and there's a bolt hole for the timing cover that's completely sheared off from damage that was not pictured in the ad.

Anyone know a good welder that could fix something like that? Would need a bit of metal built back up and then drilled/tapped. Not sure how hard that is to get right on a gasket surface.

Also wondering if I can accurately test for compression turning the motor by hand.

you need the engine to turn quickly to do a compression test, meaning you need to use the starter

the hole you speak of is in the block? I'd return it

Yup.

And Yup.

Given your tight timetable for this project, it's likely not going to happen, or won't be cheap enough to make it worth it.
