More Problems with the SP

Seeker 77 · Post by **Seeker 77** » Fri Feb 23, 2007 7:19 am

There is bluish smoke coming out of the rear cylinder exhaust can, any thoughts? It can't be a generic problem as there is nothing coming out of the other silencer.

Am thinking it could be a gasket on its way? It recently had its clearances done so it shouldn't be the valves.

Any help would be much appreciated....

Hi Mellis,
This doesn't sound good

Is it all the time or just when starting from cold? Have you recently had an oil change? Has it only been doing it since the valve clearances have been checked? Are you sure it's oil and not a corrupted power comander map pushing too much fuel through(Smoke more black than blue)?

blue smoke is usually oil,if its burning oil its getting past the piston rings OR its getting past the valve stem seals,run your finger round the inside of the end can to see if its sooty or oily,it don't sound good

It only does it when hot, and only when you blip the throttle. It doesn't affect the performance at all but the smoke is definitely blue

I fear a quick sale may be on the cards......

The other thing that i was thinking was that it may have been caused by a little V-max trip up the autobahn, speedo reading 184

Maybe that has caused the problem.....

Jammy git, Iv'e got to make do with the M4 and I can't get mine over 70 nomatter how hard I try

Sounds silly but keep and eye on your oil level. If the preformance is still there (and it obviously is) it could just be a leaky valve seal. That wont cause much of a problem unless you start burning a lot of oil.You coud pull your plugs out and see which pot is causing the trouble by the colour of the burn. If it's loosing/using a lot of oil I'd get it into a work shop and hve an estimate before you descide to flog it. It could even be a leaky gasket and not cost too much at all.

Will try that mate, thanks

I would agree with whats been said

Blue smoke = it's burning oil

Possibilities as already mentioned, if it's only valve stem seals it usually smokes more on start up than when riding it, if it's a piston ring gone that's usually more noticable after going down a steep hill (using the engine for braking) once you open the throttle to power up the other side, the best way to check the latter is for a mate to follow you

Just a thought (probably a load off boll**ks) I don't suppose you've been wheeling your bike a lot just lately, like since this problem has occured

Cheers,

Chris.

How difficult/hard to change is a piston ring??? Or more likely, how expensive will it be to get someone to do it for me?

Well have you

No, not really!! Does that make it more or less likely to be the piston ring!!?

It was only a long shot

I know some of the Ducati's if wheelied a lot end up with oil from the engine in their airbox, so working on that, I just thought, may be you had oil in your airbox and it had found it's way into the engine via the air intakes, which would give you the same symptoms

Thanks Chris, will pass it on to the engineer folks! Mark

You're very welcome Mark

It's a abit of a mystery really, as I would have said Honda engines on the whole are normally pretty bullet proof in that department

Hopefully it won't be to serious

Nows there's a good thought Chris. Mellis, take the tank off and have a look inside the air box. If you've been over reving on the auto bon it's quite possible the breather pipe from the cam cover has spat some oil into the airbox. I used to have that happen every now and again on the Storm it might be the same on the SP.
I still think it's unlikely it's an oil ring.You'd loose performance and leave a smoke trail like a two stroke
