harley question, non-harley fans look away now

[reckless_b]

Hi, I have a 883r 02reg, I've had it about 5 years and every year promise to get some use out of it and maybe uprate it to 1200.
My question is though, is there a quick and easy way to find out whether this has already been done? I'd hate to buy a 1200 kit and find I've already got one. Cheers guys.

If you don't want to take a cylinder head off, to measure the bore, you can fill one cylinder with oil from a burette, through the spark plug hole and see how much it took at top dead centre and at bottom dead centre. The difference is the swept volume of that cylinder.

I looked...





You have your answer Sir.


Oh and to get better use of the beast move to Florida/California. At least they get 'Harley Owner Weather' there.

A lawyer chap who lived next door to a place I lived in Fl. had a big eff-off Gleaming Harley. Pretty bike.
It was out twice I know of. Once to get serviced and once to get valeted.

I really enjoy any ride out on it, and as my zzr is now destroyed it will move up the ranking for use, beautiful bike though, pity about all its short comings, speed, power, handling, but I can live with that😍

Sportsters are fine bikes.

Easiest way to check is to look through the pile of receipts you have with it. Or take it to a Harley dealer.

Reminds me of an old joke-what's the first journey an 883 makes? Off to buy a 1200 conversion kit.

Any part numbers stamped on the cylinders?

Harley's new 750 bikes could be worth a look

Shirly you can tell the difference between an 883cc engine and a 1200cc one......that's going on for twice the size If not, why bother? If it can nearly keep up with something like a little RD200 at the lights, it's probably a 1200
How easy is it to get the the carb jets? 1200 have 45 slow jet and a 175/180 main.

To answer the OPs question, and to pick up on what someone else suggested, look through the big pile of receipts.

A dyno run might not tell you that much. There isn't a huge difference in power output between the 883 and the 1200 - maybe 10hp - but there is a big difference in torque.

It's also quite hard to pin down just what the standard power output should be on an 883. It can vary from about 40-60hp depending on the state of tune. A stock one is very similar to a superdream to ride, in terms of power output and noise.

The 1200 conversion can also have many different flavours - you can use 883, 1200 or buell heads. You can go for new harley barrels and pistons, have your existing barrels rebored, maybe go a little over 1200 with aftermarket pistons.

So I would look in the paperwork, or measure it with a burette.
