This might be a stupid question, but I’ve never had to lift a bike before,

I'm about to do a Cam swap and I’ll need the rear wheel off the ground. I do not have access to a motorcycle lift table or a wheel chock.

I do have access to a good scissor jack. Is it safe to just raise rear wheel off ground using scissor jack even with out the wheel chock?

Or do I need to make something to chock front wheel.

 

There are CHEAP jacks on Amazon that will lift the bike, like 50 dollar jacks like the type that are used on lift tables

They are rock solid because they are wide... they support quite a bit of the bike

I actually have 2 of them.... they keep my bike in Florida off the ground when I am not there.

If I were you, I'd get one, but failing that, I'd use the scissors jack just enough to get the bike supported under the frame in 2 places on some heavy duty lumber.

 

Something like this?

check the Denver Craigslist for 'motorcycle lift'
..... i got a lift for quite cheap, works well

 

I have one of these:

and one of these... which is my primary jack

 

To answer your question, is it safe? I'd say, there are safer ways (like using two scissor jacks to lift entire bike), however, you are only lifting it 2 inches... As long as you use proper precautions, it will be fine. There's so much weight up front, I wouldn't be concerned. You can always put the front wheel against a wall, clamp the front brake lever with string, put a brick in front of it, etc.

I removed the taillight assembly by using my craftsman motorcycle to lift only the rear (by sliding the jack toward the rear). Lifted the rear so I could remove the wheel to access the bolts. The bike was plenty stable.

Also, since you're only doing cam work, you shouldn't be muscling anything around, but keep in mind not to push or pull too hard and shift the balance (the same could be said even if you're using a proper jack).

 

First check the rear axle, if there is a hole through it you're almost there. Get a piece of 3/8 - 1/2 round stock steel rod cut with an extra inch on either side.
Get a universal race bike stand, usually $50 or less used. Slide the steel rod through the hollow axle and lift. Good to go and safe as anything.
Works on the front or rear of the bike, if you need to remove a wheel put some jack stands under the frame and remove the race stand.
Simple, cheap and very safe....cheers!

 

Several DIY video on UTUBE using 2x4.

I'm not recommending them but of course they would work.

A proper m/c jack will pay for itself.

 

i have one just like it. Ball bearings rolled away like chicklets first time I used it. Once I changed out the bearings it has been fine. Wasn't very expensive to fix.

 

Bend your knees and lift with your legs.
But a scissor jack is fine.
If you can tie it off on either side with ratchet straps through
the fork trees to hold it upright would work too.
