docc Posted February 7 Share Posted February 7 I have looked and looked, but cannot find the discussion we had about this impressive lady rider. Any recollections, links, or insights? 2 Link to comment
MartyNZ Posted February 7 Share Posted February 7 Katarzyna Jaskulska. https://themotolady.com/katarzyna-jaskulska-wheelie/ @dangerous wrote an extensive commentary about her here : https://www.v11lemans.com/forums/topic/19384-gratuitous-pics-of-girls-guzzi/?do=findComment&comment=211626 1 3 Link to comment
docc Posted February 7 Author Share Posted February 7 Thanks, @MartyNZ, that was the post (by @dangerous) I recalled, but could not find . . . " thats my Polish friend ;-) Kat unfortunatly she parked that bike under a car... " I do not know how to interpret that statement. Did she survive this event? [edit: I restored the image links on that thread.] Link to comment
LowRyter Posted February 7 Share Posted February 7 IIRC she bought it. Sorry to report Link to comment
KINDOY2 Posted February 7 Share Posted February 7 It is Katarzyna Jaskulska, that was a false rumor..She was in a bad accident not long after this shot.., a car went through a stop light and hit her ..but she was not terribly hurt . Professional Stunt rider..She did not die..she is still with us. 4 6 Link to comment
p6x Posted February 7 Share Posted February 7 At least she does not pull stunts like the late Olga Promina... My favorite motorcycle stunt lady happens to be French. Chances are you have seen her in any of the movies she describes below. 1 Link to comment

Guzzi-in-Vancouver Posted March 6 Share Posted March 6 For those who might be interested she's quite active on an FB Griso group and has a lovely bike to boot, an 8V Griso modded to 1.5litre & 120HP. https://www.facebook.com/groups/622200605964629/permalink/843931140458240/ 1 Link to comment
dangerous Posted March 9 Share Posted March 9 Kats looking good... and has boosted her 1200 Griso, that is some increase... 2 1 Link to comment
pete roper Posted March 9 Share Posted March 9 Oh for fucks sakes. Yeah, believe it. Then look at where the torque and horsepower graphs cross. There are also huge problems with crankcase pressurisation and oil expulsion if you increase the swept volume of the motor. I do tire of this bullshit. 1 1 Link to comment

The dyno graph is from this mob: https://radicalspeedshop.com/motor_getriebe They are well known here, and allegedly do good work. The 1200 to 1400 conversion apparently involves heads and barrels from the 1400 California models. I gather it is not "bolt on", but rather involves an alteration to the oil galleries somewhere. There are a couple of blokes in the german forum with the conversion, at least one in a Griso, perhaps all of them. The whole business is very expensive, and whether it is a good idea is debatable at least. Getting it legally on the bike's papers here is presumably impossible. What it does to the reliability is also a very good question. Despite all that, the first-hand reports that I have read all said that the motor works well, and is enormous amounts of fun. If I had more money than I knew what to do with, I'd be interested in trying the conversion in a Norge. I think that would work nicely. Link to comment
pete roper Posted March 9 Share Posted March 9 I've built two single spark 1400's. There is a lot of work involved. Torque is prodigious. Outright power increase is minimal. Enlarging the motor produces big difficulties with oil expulsion/crankcase pressurisation. As you say the oil cooling circuits between the single spark and twin spark engines are entirely different and I've never heard an adequate explanation of how these people have addressed that issue. The reason why much greater power is well nigh impossible to get is because of the side draft head design, narrow included valve angle and combustion chamber shape. Effect of cam changes will be minimal. I don't doubt that they are fun to ride, I just don't get why people have to make silly claims for them. 3 Link to comment

Lots of people been saying there’s no more power to be gotten out of V8’s down at the drags for years… Until somebody comes along & proves ‘em wrong! 😂 Link to comment
