ROCKETSPROCKETS? (Do I already have 'em?)

How can I tell whether-or-not my second-hand bike has them fitted already?

EDIT? I have slightly re-phrased this question so it makes sense.

Take the sprocket covers off and have a look at the back of the sprockets. If they don't look like the ones shown on the Boxer Pereformance website

http://www.boxer-performance.com/products.htm

then they are not Rocket Sprockets.

Not easy to tell from the pics

Probably the best way to tell is to open the throttle on a flat road at 2000 revs top gear mine will pull with very little complaint even two up and will pull smooth from 2500

But mine's not stock in other ways, this may have a bearing on things,

Hopefully someone will be along that can give you a better discription
from memory i think the OEM sprockets have bigger arrow markings on them but you won't notice this without having both sets there, the later rocket sprockets have five holes plus the centre bolt hole the earlier one's had four the OEM have four offset holes again doubtfull if you would notice this when fitted also the OEM one's have the positioning lug pressed in the rocket sprockets have a pin sweated in again not noticable when fitted

Hope this helps Dai

If you can wait until this evening I can post a comparative pic I had taken while I was fitting my sprockets.

Here you go:

OE

Rocket Sprockets

Note the OE has an indent to locate the sprocket; Lennies has a pin. The end of the pin is visible as the sprocket is rotated.

Hmmm, looks like the nut has to be removed to see it tho?

Just compare alignment arrow styles

Errrrrrrr......not wishing to state the bleeding obvious here but the Rocket Sprockets have BP1 (Boxer Performance) stamped into them!

Strange tho,:? Why stamp one and not the other

Both of mine are stamped BP1.

I think these two are from different batches as the arrow's are stamped differently

Where's Mr Lennon when we need him?

Check the valve timing...

All sprockets up to the newest batch will have one or both sprockets stamped with BP1 as stated and it is not covered by the retaining bolt and washer.

If not fitted, send me an email and order a set as you will be happy with the result.
