    So since I have had Airheads, and way before. I have LOVED the way the R65LS looks. First time I remember seeing one was in that movie which I think was called the day after. Loved the red one in the movie with the white wheels. Anyway, I know they are slow and do't mind because this is what i want to do to it.

    R80 motor with ported dual plug heads, HC Seibenrock big bore kit, the power kit extra, 34mm Mikuni flat sldies, and of course I'll retain the stock airbox since I get caught in the rain every once in a while. I'll also want to do a high performance clutch and the suspension will get up graded with Ohlins shock and a fork job. For some odd reason, this is my all time dream Airhead since I love the looks and for an Airhead, it'll be fast, especially for an R65LS.....and I KNOW it won't REALLY be an R65LS but no one will have to know that. :rofl

    I'll wait for the more knowledgeable here, but given that the R65 is sort of unique to the airhead "family", wouldn't spooning an R80 motor in there require a fair bit of modification?

    Just wondering, don't know myself. If you do end up doing this, please post your progress.

    I know Wirespokes has an 850cc upgrade with Mikunis. He will know how that is done. I think it is with stock BMW pistons/cyls. Now that would be a super way to make a sleeper out of the R65. I like the Bings so much I would go that way.

    I will spoon in an R80 Motor with the upgrades show done to it. I will not only leave the R65LS motor alone for reliability but for collectors sake as most who want these things will want the stock motor IF I ever sell it. Which after all this work i never would!

    I can't stand the stock Bings compared to the mikunis. After a set of mikunis goes on an airhead and you FEEL the increase of power, you'll also hate the Bings. My R100RS wa NIGHT and DAy better with a set of 40mm Mikunis on it even thought the Bings were as perfect as they can be before that swap.

    The 65Ls is supposed to be 55 BHP. Well it is in Europe, I think the standard 65 engines too nice to swap out for a bland 80 motor.

    So here in the US that would be about 19bhp then. I rode one and it felt SLOW compared to a naked R80.

    I've owned one, and ridden another. One was hotrodded like crazy, mikuni's, dual plug heads, lightened flywheel, etc. The other was a friend's, who I helped get on the road. Bought mine for 700 bucks, needed new gas, oil, and battery (guy thought it needed a starter and more). My friend's needed a lot more, but for 500 bucks, not a bad deal. Bone stock, with either 160k miles. Cylinders still have crosshatching. Honestly, my friends felt a lot faster. Better torque too. When the bings are right, they run really well.

    The engines mount the same. The difference between the engines is really only limited to stroke (shorter on the r65, type 248).

    Go for it Man!!! :clap

    I have a R65LS to 'One day' restore too :freaky

    You have given this a lot of thought!!!

    This sounds like a great plan, go with the hotted up R80, great choice :thumb

    The amount of work to do a 850/650 is more than the quality powerup kit

    Fit up a set of 4 piston Brembos on the front too off a K1100.

    I will subscribe to this for sure :lurk

    bigger motor bolts right in, very little to modify. friend put a r100 engine in his wifes, made it pretty fun to ride. always wanted to do it to mine, but never got around to it.
    loved riding the LS though, even did track days with it. great handling and brakes. with the r100 engine, it would wheelie!

    Cool idea! Good looking bike too - I've always like the R65ls - it reminds me of an ahead-of-it's-time pre-cursor to the KTM Duke!

    I, being of the "inseam challenged" variety of American, have often thought that the R65, with its lowered-seat/ride height, would work well for me. I like them, especially the LS with its dual disks, and it would make a fab basis for dropping in a nice R80 engine. BUT, I have to say, all the things you hear about the R65 motor may just be so much urban-legend... they seem to last well and have reasonable power! ... and, perhaps also because of the urban-legend stuff, an R65 can be bought pretty cheap!

    Hmm... :evil

    Now that's a photograph I'd like to see. How did you fold yourself up on one of those Kev?

    Now this R65 I will have to see. And I will!

    Do you already have the R80 engine?

    Doesn't the motor sit lower in the R65? I just wonder about dragging the valve covers. The R80 motor will be wider, but I don't know if it's enuf to matter.
    I ride with a short guy occasionally who rides an R65/80. It gets his tip-toes on the ground but it seems to drag hard parts before my /5 does.

    I don't have a motor yet, but am on the lookout for a cheap one that hasn't been molested. It is a long term down the road project, but I really want to do it. Maybe I'll get lucky and find a cherry R65LS in trade for my 1973 CB350F....:roflor some other nice Airhead....
