[@ w Z w .... o > o 250cc KAWASAKI F-4 CLUTCH ADJUSTMENT While many riders realize that they have a method of adjusting the slack out of the clutch cable at the handlebar, not to many are familiar with the procedure of primary adjustment at the dutch. The adjustments on the levers are mostly for a little adjustment while you are riding, but to properly adjust a clutch, you first start at the dutch adjustment. As the last Workshop was on the carb and oil pump of the F-4, you may have noticed that the adjuster is located in the same area beneath the right-hand cover. Before attempting this adjustment, you first must run the adjustment at the lever all the way in, giving you as much slack as possible, then go to the adjuster on top of the case and do the same thing. By this time, you should have a real sloppy loose clutch handle. It is best to do this with the machine on the side stand so that there will be less chance of oil spilling all over the floor when the cover is removed. 1.' As shown last week, if the brake adjustment is backad off and the foetpeg bolt loosenad so the peg will swing down, the peg can be used to hold the brake lever out'of the way while you are performing the cover removal and replacement. 2.1 Also as when wor1< ing on the carb or oil pump, the right·hend c:over is taken eway by removing the five Phillips scr..... (arrows) es shown. If these are in so tight as to damage them when removing them, an 'impact driver' should be used. If you have never used one of these, they are worth their weight in gold; ask your deeler to show you how they wor1<. 3.1 With the co_ removed, this is what will confront you in the clutch area. In the center of this mounting triangle is the adjusting saew with a lock nut. As this adjuster is threaded in, it takes up slack in the clutch ae:tuating mechanism and mo_ the arm securing the cable downward. Back off the lock nut two or three turns with a 10mm wrend1. 4.) Now hold the nut in position and with a screw driver, run the adjuster screw down until you feel it take up all the slack. This can be felt as a resistance to turning it eesily. When it has bottomed, tum it ONE MORE FULL TURN to meke sure you have taken up all the cable slack, then BACK IF OFF TWO FULL TURNS, still holding the lock nut stationary. Now run it down with just a light feet on the screw driver, when the resistance is felt this time, STOP, now BACK IT OFF 1/8 tum so the adjuster is not pressing against the dutch (if it has preaure, it mey cause the dutch to slip). Now, holding the adjuster in position with the screw driver, tighten down the lock nut. Next. take out the cable slack (if any) thlll is left with the adjuster at the top of the case. You must 1 _ a little 10 thet you have the correct f'"1>laY at the 1_. Button the co_ back up and you should have all of the hendlebar adjustment to go again before you have to go into the case again.

Classes: Under 5 races Over 5 races 100 100 By Bill Hanner Three new prospective off·road riding areas which are under study by the San Diego County Supervisors along with the type of area proposed and the estimated cost of readying each area were disclosed at a recent Off Road Vehicle Institute (ORYl) meeting in San Diego, Calif. They are: Cactus Park, 50 acres near Lakeside which will cost 144,500 to ready for off road recreation; Sycamore recreation area, also near Lakeside, which is estimated will cost 132,000 to prepare; and Ocotillo Wells in Borrego desert, which will have a proposed space for 400 campen, and will cost 157,500 to prepare the facilities for off road recreation. Two privately operated locations were announced that are now accepting motorcyclists at reasonable fees one has an extensive race course. They are: Four Comers, in the Ramona area and the area East of highway 395 in Miramar. The San Diego Motorcycle dealers have presented ORYI with 4 motorcycles which are to be given away at Southbay Speedway during motorcycle races on July 2nd and Sept. 12th. You may join ORYI for the regular $2 annual fee and receive a chance on a motorcycle free or you may make a donation to ORYI and receive a ticket. All proceeds will be used to meet the expenses of the organization. The four bikes are Yamaha, Honda, Kawasaki and Suzuki. In order to impress upon the ORVI members their importance as a lobby group as motorcyclists, a brief review of the compendium, "THE MOTORCYCLE INDUSTRY IN CALIFORNIA" was presented. Some of the most impressive economic figures were; in 1970 the sales of motorcycles, parts, accessories and service amounted to 1131,000,000.00. The total amount contributed to the economy of the state amounted to 1533,310,000.00 in 1970. Total registration fees for new motorcycles in 1970 was 112,354,080.00. Other disclosures were equally as impressive and it is obvious that with that kind of an impression on the State's economy, letten and telegrams from motorcyclists, voicing their unified opinion on advene legislation will be heeded. It was also voiced that when addressing letters to government representatives that a simple hand written note will be heeded more than a professional1y composed, mimeographed form letter and it was urged that all ORYI memben take this into consideration when writing their representatives; local, State or National The next meeting of ORYI will be held at the Valley Room of the Mission Valley Inn at 7:30 p.rn. on Thurs., June 17. All ownen and riden of off road vehicles are urged to attend and give their support to a group that means to get things done by doing something about them rather than just talking.
