The G5 owners manual has break in instructions on pages 44 & 45. I always recommend following the instructions. Go to my website-http://www.vincesmc.com/myths.html#engine for a more in depth discussion..
I'm brand new to all this but it seems to me if I'm going to buy a bike ofr close to $7k I damn well better be able to ride it at highway sppeeds or any other sppedd for the matter a lot sooner than what the break-in instructions are in the manual. I think the important thing is not to abuse the bike and to make sure you varyyour speedds work through all the gear but most importantly ride it the way you intend to use it and do the maintenance as staed in the manual. The UCE and AVLs for that matter are moderna bikes in every sense of the word except for looks so ride them and break them in as they were modern bikes. As far as the RE dealship near Olpympia is concerned they don't have any nwe REs on the floor and very few old REs around not to sure how much advice I'd be taking from, someone who doesn't have any moderrn REs to let you demo or to sell you. Just my humble opinion.
Referring to Vince. I am not sure why he doesn't have any G/C5's as you say.Probably a waiting list and or economy reason's ,he will probably chime in. More about Vince ,he is a the only dealer that regularly post with allot of very helpful info.The other guys are probably busy making money.Now ,I have visited Vince's shop back in Christmas of 2007( he might even remember me) the place was loaded with RE's. Yep, I almost bought the bike I believe Birdmove now rides.(getting scary isn't it?) (I had no way of getting home).Vince was very helpful and informative.I have no doubt with his knowledge. He is a real RE enthusiast and stays in the know,though CMW, and who knows he might have a 1-888 number direct to India.Now all that being said I have given Vince a load of bull more than once on this forum, but he has earned it though longevity, and always in fun.Careful about labling, oh I purchase in Alaska due to shipping reasons.So take it easy on Vince.
