Dave Roper, the first American ever to win an Isle of Man TT, will be riding a restored 580cc Indian TT model v-twin in the 2011 TT. Roper has a lifetime of achievement in vintage racing, including more than 20 AHRMA national championships as well as his win of the 1984 Senior Historic TT on a G50 Matchless. Support the first motorcycle to ever win the Senior TT on the Mountain Course, the only American marque to win at the event and the only American racer to ever win the Senior Historic TT!
22-24 April, 2011 AHRMA , Willow Springs, Ca. I raced Mike Bungay's 350 Aermacchi and Gary Roper's '51 Velocette MAC. The Aermacchi is a well developed street bike motor in a one off racing chassis that bears some resemblance to a Ducati TT 1/2 trellis frame. Mike lives in Sacramento and I've ridden this bike many times. The Velo has a rigid rear end with telescopic forks and 21" front and 19" rear wheels. The MAC model is 350cc but is running in a 500cc class, Class 'C' foot shift. Gary and I don't know how we are related, but there must be some wandering gene there somewhere that must go back to Sylvester, inventor of the steam motorcycle. Gary lives near Ashland, Or., and came with his son John. Fri. I did a half day of practice, going out first on the Velo. It vibrated like crazy and I decided it was geared too low/short. But, the good news was that it shifted fine after having a reverse camplate and close ratio gearset installed since the first time I rode the bike at Miller M/S park, last Sept. I then went out on the Aermacchi and decided it was geared too short, also. While Mike was changing the gearing, I noticed the swing arm was cracked, so that bike was finished for the day as we arranged to get it welded over night. I went out again on the Velo with one more tooth on the gearbox sprocket and it was better but I thought still too short. It was a bit hard to tell as the bike has no tachometer. I also ran Ron Halem's 500 Goldstar to shake it down and evaluate it prior to it going to the Isle of Man for the Classic Manx GP where Kevin Murphy will ride it. Sat. practice, I rode the Velo with yet another tooth on the G/B sprocket and it seemed good. The Aermacchi, with welded up swing arm and taller gearing initially seemed good, though I decided the front wheel was out of balance/round and on the last lap it started running funny, sort of surging. Turns out the front tire was out of balance and the intake manifold was very nearly broken off all the way around. Off to the welder again. For Saturday's Class 'C' race, there were four entries Fred Mork on a Garden Gate Norton Manx, Ted Van Doorn on a Matchless G80 and Ken Genecco on a Vincent Comet. I got a good start and led for the first 3 laps, but then the clutch started to slip and Mork came by. I was able to nurse it to the finish in 2nd. On the Aermacchi in 350GP, I got a good start and led initially behind Ralph Hudson leading Formula 250 on a TD-3 Yamaha. First, Dave Crussel came by on his 350 Kawasaki Bighorn in F-250, then Jim Neuenburg motored by on Fred Morks short stroke 350 H-D/Aermacchi. Jim went on to lead overall briefly before Crussel got back by him. I got ahead of Hudson when he ran off the track, but he recovered and passed me back. The front fairing bracket on my bike broke almost immediately allowing the fairing to bear against my left hand and clutch lever. It wasn't a huge problem, but was distracting as was the fact the my leathers started to unzip. I finished a distant 2nd. Fixing the fairing bracket wasn't a big deal but, on the Velo we found the the gearbox adjuster bolt had broken, allowing the rear chain to pull the G/B back making the primary chain tight as a banjo string. Gary had no spare, so we had to weld it. This involved indexing it so the thread lined up, beveling the ends, welding it straight, grinding down the weld and finding a 7/16" X 26 tpi die to cut thread over the weld. Amazingly, it came out beautifully. The clutch, however, was wasted an a call went out to Tom Ross in Riverside, who owns a MAC. Tom drove up to Willow Sun. morning and helped install the necessary clutch parts. In Sun. practice, the Aermacchi started backfiring on decel, and I told Mike to look for exhaust leaks. Sure enough, a bracket had broken off, taking a chunk out of the pipe. Back to the welder. We clearly have a vibration problem. I didn't get to practice on the Velo as it took all morning to install the clutch and primary drive, but I was able to do one 'scrub lap' on the warm-up lap of the first race of the day. Again, in the Class 'C' race, I got a good start and led into turn #1 and continued to lead all the way through the last corner on the last lap when Mork motored by my 350 with his 500 for the win. In the 350GP, another good start and and I led briefly overall when Hudson ran wide in turn #3. Hudson came back by, then Crussel on the Bighorn. At the end of the 2nd lap, Neuenburg motored by, but I was able to pretty much hang with him untill the 6th lap when my Aermacchi made a bad noise and I stopped. Mike takes these failures in stride, is undaunted, and is determined to find some more power. Gary has big plans for the Velo, also. A good event despite the wind, which is always a nuisance at Willow, but probably the worst I've seen it.
