[QUOTE="hadronuk, post: 73526, member: 1866"] Below is a copy of the fitting instructions I have asked AVO to put out with every unit. I would appreciate feedback on anything that is unclear or omitted. (PC1511 is the part number for the standard length coilover. PC1507 is the part number for the shorter version that allows a slightly lower seat height. AVO have decided they will continue to offer both versions.) [B][U]Fitting AVO Vincent Dampers and Coilovers.[/U][/B] When fitting all units be careful that it is not strained sideways. Do initial road testing with the damping adjustment turned fully anti-clockwise. (Softest) [B][U]Front Damper TA1447.[/U][/B] Check that the mounting points on the bike are accurately aligned, particularly the lower eyebolts. AFTER FITTING THE NEW DAMPER, CHECK THAT WITH THE FORKS FULLY EXTENDED THERE IS ADEQUATE CLEARANCE BETWEEN THE MUDGUARD AND THE EXHAUST PIPE ETC. This is particularly important if long eyebolts are fitted[U]. [/U] [B][U]Rear Dampers TA1445 & TA1446[/U][/B] THESE REAR DAMPERS MUST ALWAYS BE FITTED WITH THE 0.4 INCH LONG STEEL BUSH FITTED IN THE TOP EYE. It is important this is used to ensure that the damper top mounting is free to rotate independently of the spring eyebolts. [B][U]Rear Coilovers PC1507 and PC1511[/U][/B] Check both spring bolts are straight and are a sliding fit in the coil-over before it is fitted to the bike. Tighten the spring pre-load ring enough to ensure it will clear the RFM. Fit the top mounting first. Fit the front (top) spring bolt and the spacers supplied and tighten it firmly as this stiffens the top mounting point in the UFM. The top eye is fitted with a steel bush specifically to allow this. Check the damper and spring bolt assembly can still rotate freely in the frame. Take care fitting the rear (lower) spring bolt, as it can be a little difficult to get the RFM and coilover accurately aligned. An assistant lifting the rear wheel is helpful. The rear (lower) spring bolt should be tightened just enough to ensure it does not come loose. Overtightening may crush the spacers onto the spring bolt, making them difficult to remove. [B][U]Coilover adjustment in use.[/U][/B] Note that excessive spring preload may allow the spring to become coil-bound on full bump. (If a heavy load is causing bottoming-out, the damping can also be increased a little.) With the suspension fully extended, the spring length should not be less than the following: [B]Unit and Spring[B].....................................Min Spring Length[/B][/B] PC1507 with 275lb/inch spring.............................6 1/2 inches PC1507 with 350lb/inch spring.............................6 3/4 inches PC1511 with 275lb/inch spring..............................6 3/4 inches PC1511 with 350lb/inch spring..............................6 7/8 inches RAS 10/08/16 [/QUOTE]
