CBR1000 Engine angle?
DANMAN - 4/8/17 at 12:56 PM

I am currently in the process of changing my engine from a 1998 CBR900 to a 2005 CBR1000 but was wondering about the angle of the engine? I had the engine dummied up in place with the small flat part of the sump resting on a piece of wood on the floor but noticed the Honda logo on the case wasn't level which I thought was odd as I would have imagined Honda would have had their logo on the casing parallel with the ground when the engine was in the bike. I pulled the engine out to have another look and noticed the Hionda logo and the bottom of the block are at different angles to the sight glass markings and bottom of the sump. My plan was going to be to be to go with running the engine at an angle where the sight glass markings and sump are parallel to the ground as that makes more sense to me (level ground for checking oil and all that) but just wanted to see what others thought?

I can't really tell anything from that picture as it's so big. Try resizing.

Don't know about CBR's but R1's are commonly mounted at an angle compared to how they are in the bike.

Front or mid engined?

If front you'd be better with a billet sump, then place a piece of aluminium underneath the sump when the engine is resting to take it 2-3mm off the floor level.

Also removal of the original sump will lower the air box and get the engine mass closer to the ground.

You will find the sump didn't sit level with the ground in the bike.

If you get the Honda writing level that is how it would be in the bike,you will also then have the sump to block joint level with the ground.

Not that any of it really matters now it's in a car!

Thanks for the input guys. After a lot of googling trying to find a pic of the same model bike without fairings on it (surprisingly hard to find) it looks like the bottom of the block sits at an angle with the ground and the small flat section of the sump is parallel to the ground along with the sight glass lines so I think I will mount the engine at this same angle in the car.
I will be getting an AB Performance baffled sump to fit as soon as I have flogged off some of the old parts of the rest of the bike to re-coup some cash.

I am just on with putting a cbr1000rr7 in my striker and have an ABP sump on it, the Honda logo looks to be fairly level. My sump sits slightly at an angle but will be leveled out with spacers.
I will say that I thought it would be a quick job but like like most jobs it is taking longer than I thought it would. I am sorting fuel system and engine loom at the moment.

The plastic pipe hanging down is what the engines previous owner used instead of the sight glass to see the oil level.
