I got a bmw r80rt which i have stripped completely of all luggage & fairing.

any help would be appreciated.
Thanks.

Simple answer is yes, You can do a lot to one of them. A good start is the heads, valves etc. Get a specialist to work them over. Carbs can be replaced too. You can get it dual plugged and so on. The older boxer engines are easy to work on.

What a helpful bunch you all are, I'll do that, thanks.
Been asking for ages but all i get is, thats an old man's bike. That may be true but, it hasn't let me down for the couple of years that i've had it.

I've had my R100RT for over eleven years and it's been a brilliant bike - it's taken me all over the place with very few problems. It may not be fast but it gets me there and it's very comfortable.

yes, you can do a lot with the old beemer. first of all, and probably cheapest, what airbox are you using? the older airbox with the smooth castings in ally and the round cylindrical air filter flows better than the later flat filter type, as the later one was fitted to help lower the bikes noise levels, the pipes are pretty restrictive too, i had reverse cone meggas on mine from a commando, then you can whip off the heads and clean up the ports just a bit of a polish and clean, nothing too radical. i fitted r100rt heads froman early model, with the 40mm bing carbs and it absolutely flew. i had a sidecar on it, and with me the wife and two teenage kids in it, and a trailer tent on the back, it would still cruise on the motorway at 8o plus. the heads and barrels off the 100, or r90 will just drop straight on, the r90s being best, as it has a pair of huge dellorto carbs, but they are as rare as hens teeth though, and very very expensive. then theres twin plugging electronic ignition, hot cams, an endless list of tuning stuff is out there. if i were doing it again, i would go , airbox, pipes, big bore kit and polished heads.

Definately yes. Theres a friend of mine Hami who has an ex-police one that was used as an armed response vehicle that used to pull wheelies b4 he fitted a sidecar.
