o 00 CJ) 16 ways makes winning difficult, and his bike has always got a double dOle of ho~. But Roberu'luck at Daytona IS just about as bad as a penon could have, 10 I'm counting on Roberts' luck being the same. He won't fmish. I'm just considering Roberts out and then re-arranging all the luck down the line. If nothing happens and Kenny finishes, I still think that if the fourstrokes are fast enough, then Roberts may have a chase on his hands. But if everything goes Roberu' way, it will be II cMse. Dale SiDgletonlTaylor White Yamaha/two«roke Dale always goes real fast at Daytona. He had a lot of problems in the last half of the 1979 seuon though, and I'm not real sure how he's going to come out of that problem. I don't know if that psychologically bothers him or if he will come back to Daytona with the same energy as he had last year. Last year at the stan of Daytona he looked like he was mentally going to win and then he did win the race. He was really pumped. He had his pet pig there; he had everything going for him. But I have a feeling that it's going to be a little bit tougher for him this year than it was Iut year. Dale will be right up in there. He'll be competitive, for sure. But he won't win. llaDdy Mamola. I don't know what kind of machinery Randy will ride at Daytona, whether it will be a two-stroke Yamaha prepared by George Vukmonovich or a Suzuki GB Fonnula One four-stroke or even an RG500 Suzuki two-stroke, 50 I don't know if his machinery is going to be competitive. But Randy should really be mentally up for Daytona. He's been getting a lot of European experience. I watched him last year. I raced with him for a little bit at Daytona in the 1979 200 miler until I got sideways in the chicane and lost the leaders. He was riding just fantastic at Daytona last year. And judging by all the press I've read about him in Europe, he's been doing quite well. I think Randy will be one of the toughest competitors at Daytona this year. Randy had matured, and his attitude is a lot better than it used to be and I think that he should go really well. He may win. Skip AkalaDd/Yamaha/twO-ltroke Skip probably has had as many problems at Daytona as a person could have. Last year he was so favored to win and just didn't do anything. He had mechanical trouble all week long and one thing after another. Then be had trouble with his din track program all season after Daytona. So I'm not sure about Skip. Mentally, you have to be really pumped for Daytona. 1 haven't seen Skip. I know he'll be riding hard, but I don't know if he'll be riding on factory prepared machines again this year or not. If he's not, I think that is going to take away some of his chances. Mike BaldwinlYamaha/two«roke Well, if he's physically up for it. Mike will be a threat but 1 hope his riding strategy changes. Last year he was pushing 50 hard and he wanted to win 50 badly that he over-rode the motorcycles he was riding. I think if you want to have a long racing career, you don't try to over-ride your motorcycJe or go beyond its capabilities. I just hope that he's done some thinking since he's gotten out of the hospital and maybe smoothed out a little. Mike's probably one of the best riders I've ever seen. But I think he had a problem last year - he thought he could do no wrong on a motorcycle. I think that unfortunately he found out that he could do some wrong on a motorcycle, and I think it is a mental outlook thing where he has to get it together. I hope he does that. I wish him all the best of luck at Daytona. I just don't know if he can really be it. If there is a scale of 10 measuring hard riding, David will run it at 11 until it quits.

Dave AldanalYOIhimura Suzuki/ four«roke Dave's going to be tough. He's probably going to be the fastest rider on the Yoshimura team. I watched him ride the four-strokes at the Suzuka EightHours Endurance race in japan last year and he had a little bit of a problem stopping the machine because of the engine braking effect. I think that with time he'll catch on and fall right into the groove. His size and weight will give him an advantage over Graeme Crosby (another Yoshimura Suzuki rider), and his detennination is very strong. So, if Yoshimura gives him a competitive motoccycle, he's gonna be tough. It·s just that I have a feeling that the Yoshimura bikes might not finish the 200 miles. If they try to run the same type of horsepower that their Superbikes had last year, or maybe even try to hop them up a little bit more. I just don't know if the engines will take it. Last year when I rode for Yoshimura, when we rode them hard for very long, we had rod problems. I understand they've got a different crankshaft and some new pans, but there has yet to be any long-distance testing done on it to my knowledge. 50 the longevity of the engine is the doubtful point. But I know that David will run Wes CooieylYOIhimura Suzuki! four«roke Wes will be a threat. He's always been very fast on the Superbike Production machines. But Wes has always had problems in the GP class and he's always been just a little off the pace in GP. I think maybe he's lacking just a bit of experience and confidence. I think he'll be running good, but I don't think that he'll be up in the very fast four-strokes at Daytona. I think he'll probably be off the pace just a little bit. I think he has the ability. but I don't think that he's got the confidence yet in that class. He's never had a really good finish yet, so mentally I don't think he's up. And being mentally up is what it's going to take to go really fast at Daytona this year. Graeme Cl'OIIbylYOIhimura Suzuki! four...troke Crosby is going to be new at Daytona. He's from New Zealand and he has done very well racing Down Under, in japan and in Europe in Fonnula One type races. But the Daytona track surface will be new to Crosby, which is a disadvantage. From the ability he's shown me, I'm sure he'll be going very fast and ride the motorcycle very hard. It's just that I think that not being at Daytona before could be a factor. Among the three Yoshimura riders, I think that David Aldana has the best chance with Crosby second fastest on the team and Wes third. David EmdeIHap JODes Yamaha/ two-etroke David will do real well. He's good for finishing racers. He's easy on motorcycJes, which is imponant for Daytona. If Floyd (Erode) and mechanic Tony Smith can get together a fast engine for David, he'll be alright. I understand he's got a new sponsor, Hap jones, and hopefully his mechanics are good. He might be able to pull off a third win for the family. It sounds good, but realistically I'll have to say that the odds of him winning are against him right now. Harry Klinzmann Klinzmann will be going good, but I'm not sure what he'll be riding. As yet he hasn't had a good GP ride. Ifhe gets one he'll be good for the top 10. Richard Schlachter/Yamaha/twostroke Schlachter should be going real good at Daytona. His last perfonnances of 1970 were very good. I understand that in Europe he had lOme problems, but on the short courses over there he was doing fantastic. But once again, Daytona demands horsepower, and if Richard is doing his own engine work I think that he'll be lacking on that good horsepower down the long straightaway. It's very difficult to get that power and 50 far only a few factory machines, Yamahas, will be there. The Yamahas up front will be the factory Yamahas, the ones with factory Yamaha pans. Freddie SpeDcer/Erv Kaaemoro Yamaha/twCHtroke I think Freddie and Erv will be going for pole position in qualifying, but Erv's finishing record at Daytona is not too good, 50 I think that will be a factor. Freddie showed last year that he knows how to ride the Daytona Speedway really well. I saw him ride the 250 race last year and he was superb. The last couple of races last year on the Superbikes he did superb. I think that his ability is there and Erv Kanemoto's engines are rocketships. But they have a problem finishing Daytona, and think that might be a factor. If Erv can get his engine to run die whole 200
