Right now, I am checking the dynamic timing. I am taking care of a few maintenance items as I gradually get familiar with the machine. Lastly - if i /do/ buy a timing light with the advance functionality am i correct in thinking i can loan it out to guys that are running points? or do they not need the functionality in a timing light either.Hi, I recently picked up a 1989 R100GS. I mean, i think i know that i can turn the bean can to "advance the timing" but i am not really sure what the numbers above mean and i alwo want to make sure i understand the procedure. Lastly what is the "timing advance range" of 26, the static timing of 6 BTDC (below top dead center) and the "firing point" of 6.32 (advance) telling me? what is the "degree CS" and the mm to the power of negative one above in the repair manual? Then i ROTATE the beancan (electronic ignition) clockwise or counterclockwise until the 1500 rpm idle has the OT mark stable and stationary in the window?Īnd if it is wobbling i can check the beancan and make sure it is centered about the camshaft properly?Īt that point i go ahead and rev the throttle to 3000 rpm and - well - i guess i basically am /verifying/ (?) that the Z mark is in the window and reasonably static at 3000 rpm? and this is "Full Advance"? Then i hook up the pickup to the spark plug on the left side of the bike and point it into the hole. Then i start the bike and let i set it to idle at 1500 rpm? if so, do i do this with the throttle or turning the mixture screws? So my understanding is that i set up some fans at the front of the bike. Here are the numbers from my repair manual (let me know if i have missed something):įiring point (related to speed), deg CS 6.32 (advance) I am thinking i will have my hands (and head) full with the top end so if i can understand the timing a little better now i am sure it will help. do you mind if i just repeat what i understand and follow up on this for my r100gs? then maybe someone can correct me? It's a heavy mutha.Ĭlick to expand.hi guys. On the other hand when it's not in use it's not something you just grab under your arm and walk to a stowage area. Never an issue lifting a full boat oilhead GS or a full dress HD GeezerGlide. On the lift thing, I've had a HF lift with the optional wheel clamp/vise(a MUST have option) for 10years at least. When I bought the Craftsman it was cause my previous Sun light slid off a car fender and hit the concrete. On a good quality unit replacing the bulb is more grief and expense than the light is worth. If it's been dropped it's likely the bulb is shot. If you're going to buy a used light I wouldn't hand over the money till I hooked it up to insure it works. My current light is a Sears Craftsman w/adv knob that I bought new in the about 1972 0r 73? Still works excellent. Some of the newer ones can have a tach/RPM mode which can be handy but again not absolutely needed. I like the adv knob on mine but I use it on cars a lot and find it useful for total adv. Beware the ultra cheap plastic lights can have a really weak nippled bulb That only works well in a cave at midnight while eating black licorice. Lotsa good induction timing lights out there for way less money. that said I am basically in borrowed garage space so it will be used infrequently and needs to store out of the way. my disks have been getting a little pissed at me with all the rolling around I'm doing so I should make a move on this. any suggestions on a lift? there was a thread about harbor freight lifts but I hate to buy stuff that doesn't work precisely so I'm leery about buying HF for this item. new I see one for $200 and one that has it's own power: ģ. can I buy a used snap on and if so do I need to get one that measures advance or some other items? is there a good model number? or do these have to be calibrated at a high cost and/or is a used timing light a bad idea for a noob?Ģ. I have a new to me 93 r100gs that I have been working on and the heads are currently coming back from a refurbishment.Ĭonsequently I am planning on diving into doing a timing adjustment.ġ.
