Find the guide plug.bn The guide plug is shown in the shop manual with the engine removed from the frame and the left crankcase cover removed. (You’ll find this illustration in the “ELECTRIC STARTER/STARTER CLUTCH” chapter in the “STARTER DRIVEN GEAR/STARTER CLUTCH REMOVAL” section.) It’s a little bit harder to find it on the bike. Start by following the yardstick to see where the guide plug is on my bike. To find it on your bike, lie on the ground (or, preferably a mechanics creeper) next to the bike (without the yardstick) and peek under the shift lever and over the frame There it is, just barely visible from the side of the bike. Here’s what a new one looks like: 2. Clean the guide plug and crankcase. From the front of the bike, clean the guide plug and crankcase with brake cleaner in a VERY focused spray. Let the cleaner evaporate before moving to the next step. Page 4 Rev: Draft 5/20/2007 Page 4 of 5 3. Reposition the guide plug. a. From the side of the bike, use the yardstick (or a long screwdriver if you prefer) to gently push the guide plug back into the crankcase. (Note the JB Weld from the previous patch operation.) b. From the front of the bike, gently push upward on the bottom of the upper tab (as shown below) or the bottom of the forward tab to rotate the guide plug into the proper position while maintaining pressure with the yardstick

Start by loosening the rear cylinder down tube bolt located on the top of the old mufflers center collector in front of the rear tire. 2. Remove both of the front cylinder exhaust pipe head nuts and set them to the side for reuse with the MAC exhaust system. 3. Remove the right side passenger’s foot peg. Set the foot peg aside as you will need to reinstall it. 4. Remove the left side passenger’s foot peg. Set this foot peg aside as it will also need to be reinstalled. Note: When you remove this bolt the entire exhaust system will be loose and may fall. You will need to support the old exhaust at this point to keep from injuring yourself. Gently move the old exhaust system side to side to remove it from the rear cylinder down tube. Once the exhaust system is loose from the down tube remove the system from under the Virago. 5. Remove the bolt holding the rear brake pedal in place and remove the brake pedal from the motorcycle. Note: Set both the bolt and the pedal aside for reinstallation. 6. Next loosen the nut on the drivers right foot peg, 1 full turn to start with. Then remove the rear nut on the same foot peg. (Note: The bolt that this nut is on goes completely through the motorcycle. This is the center stand mounting bolt.) Now remove the front nut and set both aside for reuse with the MAC system. 7. Install the center stand stop bracket under the left passenger foot peg. Install this bracket with the 90° bend facing down and towards the rear tire. (Note: Center stand sop bracket in provided in the hardware kit and is approx. 5″ long with a 90° bend in it.) Adjust the bracket by one of the large bolts through the foot peg then through the bracket and then install it into the stock location. Put on one of the washers and a nut and snug up the nut. Lower the center stand until the center stand come in to contact with the bottom of the bracket. Tighten the nut until it will hold the bracket securely. 8. Install the rear down tube clamp onto the rear muffler and install the medium sized nut/bolt/washer onto the clamp just finger tight. 9. Install the (2) small bolts into the channel bracket on the rear muffler. Install the rear mounting bracket onto the two bolts and then install the washers and nuts onto each. Tighten the (2) nuts only slight amount so that you can slide the bracket front to rear to insure that when you install the bracket you position it properly. 10. Slide the rear pipe onto the rear down tube about ¼”to ¾” past the pre-cut slots on the rear muffler pipe. Slightly snug the clamp making sure that the position of the bolt and nut will not interfere with any moving parts. The final position of this bolt can hit the tire if it is not positioned properly. 11. Install the other large bolt into the right passenger and then through the top hole in the rear muffler mounting bracket. Insert the bolt into the stock location and install the washer and the nut. 12. Align the rear muffler and you can then tighten the nuts on the rear muffler mounting bracket, the cylinder down tube and the right side passenger foot peg.
13. Install the front muffler on the rear most mounting bolt of the drivers foot peg and put the stock nut back onto the bolt. Hand tighten the bolt only at this time. Note: Install the nut at this time is only to support the muffler and to insure that the pipe does not fall on the ground while you complete the next step. 14. Lift the front head pipe into position and start the stock nuts onto the studs. It is strongly recommended that you install new exhaust gasket at this time. Note: The new exhaust gaskets are not included in the kit but are available at your local Yamaha Dealer. After gaskets are installed hand tighten the front head pipe. 15. Remove the nut from the drivers foot peg bolt and reinstall the drivers foot peg. Note: Hand tighten only at this time. 16. Finish tightening the nuts on the front head pipes. (Install these nuts according to Yamaha’s Factory specifications.) Once the nuts are tightened on the head pipe you can then tighten the drivers foot peg nuts. 17. Reinstall the rear brake pedal and tighten the bolt that holds it on to factory specifications. 18. Check all of the bolts that you have installed of removed to insure that they are tight. 19. Start the motorcycle and check for any leaks. 20. You are finished with your new MAC Exhaust System.

Super Sport. The example tested by Cycle World magazine in August 1968 looked identical to the European specification 750 except for higher handlebars, a 35/35 watt headlight, larger round CEV taillight, 120mph Smiths speedometer, and an American Eagle tank badge. The headlamp shell was also different, with an additional warning lamp, and the American Eagle headlight shell featured the large hole and rubber plug (with Laverda logo) as on some early 650s. When tested by Cycle magazine in January 1969 (now called the American Eagle ‘Classic’) there was a different colour scheme, with pinstriping on the fuel tank and sidecovers (although this colour scheme also appeared in some Italian advertising and official photos). Optional for the American Eagle was a large chrome-plated engine protection bar with chrome Vitaloni rear vision mirrors attached on each side. In McCormack’s advertising the bore and stroke of the American Eagle were listed as 79.5 x 76.2mm, and this was obviously incorrect as the engine specifications were the same as the European versions. The claimed power by McCormack for the American Eagle was also Below: This Super Sport, number 1646, is based on a 750 GT, but others were converted 750 Ss. ** t he l AverdA t wIns & t rIples B IBle top triple clamp from the top. A round reflector was situated on the headlamp mounts. As there was no room for all the wiring inside this smaller shell, the electrical connectors were moved underneath the fuel tank, and there were thick grey wires leading to the Lucas switches. When turn signals were fitted these were also Lucas, the handlebar switch being on the right. The throttle was now a chrome-plated, dual-cable Tommaselli Daytona 2C, without a throttle stop, with the handlebar also Tommaselli. The dual seat on a fibreglass base, or solo seat with locking compartment, continued as before. The 750 SF1 continued to be sold in the UK, where the price was £998, but at that time a 750cc Triumph Bonneville T140V sold for £625 so the Laverda was never going to be a volume seller. In Italy, the SF1 was still one of the most popular large capacity machines available, selling for L1,227,200 when the Triumph T140V sold for L1,357,000

The launch of the sixth generation of Gsxr marked a shift in Suzuki’s emphasis on two fronts. One, the Gsxr 1000 now took the upper hand in the development stakes. Historically, the Gsxr 750 led the march-arriving first, gaining the most recent technology, absorbing the lion’s share of corporate pride-but by 2003 the Gsxr 1000 was in the lead. Two, the Gsxr 1000 represents another, more subtle shift for Suzuki engineering, in which the designers-the lucky guys who get to clothe these amazing machines-have more freedom of expression. With this generation, the designs turned edgier, sharper, more aggressive looking than ever. What’s more, the Gsxr 1000 K3 would be the proving ground for a host of changes brought to the Gsxr 600 and Gsxr 750 for 2004. In fact, nearly every upgrade to the smaller bikes appeared on the Gsxr 1000 a year before. But the real impetus for driving the Gsxr 1000 to the head of development and, indeed, shortening its development cycle was competition both on the track and in the showroom. For the track, it was understood that Superbike racing would revert to allowing 1000 cc four-cylinder bikes in place of the 750s that had been the limit since 1982. In 2002, Yoshimura and Mat Mladin barely lost the AMA Superbike crown to Nicky Hayden aboard the Honda RC5!. But it would be the RC’s swan song of competitiveness with the change to 1000 cc fours. To keep speeds in check, the AMA Superbike rules would require 1000 cc fours to have some additional limitations compared to the twins and triples. For example, “Cylinder heads may be ported and machined, but altering of valve angles will not be permitted; aftermarket valves, springs, retainers, and other valve-train components will be permitted; valves must be stock size and same basic material as original equipment; aftermarket camshafts will be permitted, but earn lift and resulting valve lift must be no greater than stock. “In addition, the “stock crankshaft must be retained, The only allowable modifications are balancing, polishing of bearing surfaces and attachment of accessory drives. Homologated transmission gear sets (one optional set of ratios per approved model) will be permitted. Optional sets will be price-controlled and must be available to any legitimate AMA Superbike competitor. Homologated fuel-injection throttle-body assemblies (one optional type per approved model) and aftermarket airboxes will be permitted. Modifications to throttle bodies will not be permitted. Optional throttle bodies will be price-controlled and must be available to any legitimate AMA Superbike competitor.” The thinking was simple: keep the liter bikes from sucking through massive throttle bodies, and the horsepower might not (and, it was hoped, would not) go through the roof. In preparation for racing, Suzuki moto wanted to make a host of small changes to the Gsxr 1000, but its motivation was also to keep the bike at the forefront of open-class street bikes. Suzuki engineers knew that Honda and Kawasaki were readying all-new models-the CBR 954 RR and the ZX 9 R had long since been vanquished-and rumor had it that Yamaha was ready with yet another push with the R1.It was the right time to make alterations to the Gsxr 1000. Heading the list was, as one might expect, a revised engine.
