Annybody have ideas of where emblems or decals can be found? I am looking for something I saw on one of the sites that had "904 GT" on the side covers. Thanks!

I haven't seen any for sale, but I'm sure any sign or graphics place could make you some.

I was thinking about (after doing the 904 of course) getting 904 waterjet cut out of my side covers, then putting a piece of chrome or something behind it, maybe perforated steel.

or making my own side covers with 904 cut out of them, polished aluminum or something.

Hey sweat....bumping your bonnie from 865 to 904 seems like a bunch of work for such a small increase, don't you think. Don't they make a 994cc kit or something like that? Just a thought.

well, it isn't much of a displacement gain, I agree. It is beneficial b/c you go from 9.2-1 compression to 10.5-1 which is where the hp and tq comes from. Another benefit is the forged pistons.

I'm breaking it down to install larger valves and the "big" bore kit, and also do a port/polish on the head.

904cc is the biggest you can go without a complete engine teardown to machine the cases.

Here's why I think the 994 kit is f*cked:
-way too oversquare to be streetable for a long time
-british customs rip-off pricing
-questionably small amount of material left in cylinder walls between the pistons and cam chain

I'm not doing the 904 for the displacement, but for the compression and forged pistons.

Makes sense.....my friends and I have often discussed how the Bonneville should be a much faster bike as it is. My pal has a '71 bonneville that's faster than his '01.....huh?

emissions regulations are what neuter the new bonnies. The cams are probably much hotter in his 71, and it probably is jetted correctly unlike the lean stock bike.

Also, the twin counterbalancers in the new engines take up some of the power too. My dealership also told me that the camshaft backlash retaining mechanism is worth about one horsepower, but I doubt that's dyno proven.

Don't forget how lightweight the old Bonnie was.

A 1971/650 Bonnie and a 2001/790 Bonnie.
No way would it be faster. maybe if his 2001 is a lemon
or Maybe if the 71 is supped up.

My 2001 is way quicker then any of my older Bonnies.
I can ride my new bonnie at 80,90,100,mph all day.
I bring my 76/750 bonnie up to 90 mph. and she feels
like she's ready to throe a rod.

Just ordered a couple of mylar decals from Decal Zone. Crossed racing flags with "904 GT" lettered on them in black and white. I will let you guys know how they look when they get here. I'm hoping all I have to do is put them on the side covers and the bike will get much faster!
