Hello All!

New to forum; just picked up an 07 Breva 1100 tonite and love the bike! Seems to be leaking oil from the dipstick area; especially after being ridden. Dried area & ck'd the dipstick o-ring seemed ok; but appears to be to small, thickness wise, to make a good seal. Made dipstick as tight as I could by hand; did not want to use pliers for fear of stripping it, due to it being plastic. Bike is like new; with a little over 100 miles on it. Was a lucky find. O-ring appeared to be in good shape; no cuts or flat spots. But looks like its not thick enough to seal the large recess where dipstick sits in engine. Possibly incorrect size o-ring installed at factory?

Any one else experience this problem? Any thoughts or suggestions would be greatly appreciated.

Thanks!
 
I find the chamfered engine oil filling hole will deform the dipstick o-ring into a weird wedge shape if I tighten the dipstick more than 1/8 of a turn after contact.

Changed mine to a new o-ring with the same dimensions as a precautionary measure, I have learnt tightening it with very light fingers force just enough to compress the o-ring and it will be sufficient to form a good leak free seal.

Picture added. New o-ring stacking on top of the old one.

Thanks for the suggestions guys!

I put a fatter o-ring on the dipstick and made sure it was fairly tight; problem solved.

Now I have an oil leak coming from the phase angle sensor; which is just in front of the left head. Doh! I pulled the sensor out and put some oil resistant sealer on the shim; sensor plate and the screws. Thought I had it licked; but after few miles; started leaking again. Looks like I may need to pull the sensor socket out of the block and reseal that. Looked on parts list and it looks like there may be an o-ring too; but I did not see one when I removed the sensor. Maybe under what I would call, the sensor socket; or holder?

Any helpful thoughts?

Thanks!

Don't put too much goo up there. The distance for timing purposes is tight (I don't remember the clearance right now). Too much material will increase the gap and impact timing. If the o-ring is missing, get one. I just coat those o-rings with some sealant and that usually takes care of any seepage from around the sensor. You can download the parts manual from this site (downloads tab) to see the correct order of sensor, shim(s) and o-ring.
 
Thanks John.

Tried to seal it last time using a minimal amount of a permatex oil resistant sealer on it; as I knew the gap was critical to proper performance. I did not see an o-ring at the time, but was not specifically looking for it. I did not realize it was meant to have one, till I viewed the parts list and workshop manual. I removed the sensor and a shim. But it looks like there is base plate that is sealed down to engine block too. It does not appear to be sealed to well. May be the cause of leak. Is it ok to remove it as well? Where does the o-ring sit; in between the sensor and the shim; or after the shim and in between the shim and base plate?

Thanks to everyone for all the good advice.

Just looked at parts manual again; does not appear to be anything like a base plate, or socket for sensor other than hole in engine block in parts view. But there appears to be another shim poorly sealed to engine block. Is it possible that my engine required more than one shim for the proper gap?

Yes. The o-ring goes between the last shim and the block.
 
Early on, my 07 BrevaI had an oil leak from the phase angle sensor too. There was no O ring on mine but on further investigation I think the O ring was put on the bike 1st in the recess and then the sensor pushed in the hole with no lubrication to allow the O ring to slide easily past and what it did was force the O ring down the hole and smeer it around the sides. I managed to clean it all out get a suitable O ring to fix the leak also there were 2 shims fitted
