Cylinder walls on the project motor - January 17, 2012, 11:21 PM

cbr 600 f4 block - YouTube


what do you think? a machine shop should be able to bore that out? or should I get a cylinder sleeve?




and here is a video of the pistons

I think that answer depends on the stock sleeve material and thickness (coated, steel, composite?) as well as how much material needs top be removed to get the cylinder cleaned up and true and availible oversized pistons.

No way to tell from the vid how much wear there is on the cylinders and how deep the scoring is. They gray shadowing at the top where the compression ring changes direction needs to be measured for sure. (I'm guessing...)

I'm not a motorcylce mechanic, but I did stay at a Holiday Inn once.

It's an F4, part it out and get something else.

Or, you can probably find a running F4 for the same cost as engine work and just swap the parts over.

it's a spair motor I bought for 200 bucks. It's my first bike motor tear down. I've worked on cars since I was a kid as well as some motor work, but as for bike's go i'm flying blind. So i'm not sure if the block can be saved.

Do you think that for the money you would be spending to rebuild it that you could find either a complete F4 or a working F4 engine in the used market?

I could understand if you wanted to do it simply to satisfy your desire to rebuild the engine on your own.

I have a running motor in the bike already with 20k on the odom. The thing that kills me the person I bought it from couldnt tell me if they kept up with serviceing the bike. So with that said I just want to make sure everything is redone on the bike and up to my level of approval. You should of seen the orginal races and the bearings for the swing arm and triple tree. So with me seeing that it made me question if the guy kept up with it and if I'm going +100 mph on the bike I want the mental reasurence that I will be alright and plus I like learning and doing that kinda stuff with my hands
