There goes space exploration, unless Musk figures out how to make an electric rocket. Chris.

How can two different race bikes be number 21? Is the whole field numbered 21? Chris.

Torco Moto Prep silicon spray works well for me. Chris.

I have a Roper plate installed in a Bellagio and fill the oil to the underneath of the plate. Never had an issue yet with this and it's a little more than what the dip stick allows. I think that semi dry dumping with a barrier like this allows a different oil level to be well tolerated. My bike when ridden hard is prone to oil expulsion from the exhaust and since installing Peter's plate this has stopped. So with the Bellagio it's not so much that you fear uncovering the pick-up under acceleration but it's more about reducing oil foaming and overwhelming the condenser. Why this short stroke engine is prone to whip creaming the oil is a mystery to me but it does in it's standard format. Chris.

Yep, got it! Don't know why I didn't before. Thanks, Chris.

Hi Docc, There are already numerous threads on this site about this but they all say to retard the ignition point when adding a second plug but surely you would advance it because the flame path is shorter and now symmetrical? No expert on where to advance but to me it has to be mapped preserving idle and keeping watch on pre-ignition. Got the feeling that I am going to learn something here! Chris.

Twin plug the head and change the advance will make it smoother.

Any third world country?

I have had another starter motor installed also with the typical click no start issue arising. Diagnosed by the local Harely electrician as a worn leading brush in the starter itself. Chris.

Wonderful link Phil, I learned a lot. Cheers.

Wow, I must bathe in my ignorance for I have only ever had a minor recall on my K75 with an unneeded steering damper and that is for about 20 vehicles owned over a 45 year period. Nothing major has broken except for a radiator top tank after 10 years of city driving and about 280,000km. Even had a GTL 500 Ducati that never broke down. My ask is, if all these modern vehicles seem prone to recall and costly parts replacement then how are they driven? Chris.

Would it be possible to insert a dampner inside if the frame front down tube? I know it sounds daft but it's the main route for vibration from engine to handle bars. Just thinking laterally here.

Rubber mounting is the 'go to' here, the Bellagio has large rubber grommets inserted into the top triple tree and it works well. The key is here as Docc says to to reduce the source or post engineer it with isolation. Isolation usually involves the transmission of the vibration through a material that has its harmonics at a different level than the source and thus it absorbs rather than resonates. Its a long path between the source ( crank wieghts) and the where its metered (the bars) and surely someone smarter than me could think of someting along that path that may help. If not, Gel filled Bars anyone? Chris.

Thanks, I have looked at the theory on Vee twin secondaries being 1.44 the counterweight each revolution instead of 2 and indeed mentioned the lateral issue a few posts back but what gets me in all this theory is that it's alawys modelled around the central shaft supplying a constant rotation and not the reciprocating motion of the pistons and thus flawed when considering primaries being in balance. Thus I think that it's a lot more complicated than just lateral secondaries. Worthy of another thread perhaps? Chris.
