I HAVE SPLIT CHAIN AND NEW LINK. AND THIS IS A 16valve DOHC not a SOHC with old push bike type chain. IT IS NOT A NIGHTHAWK, BUT MINE IS NOT ON THE LIST
Obviously some people dont read the questions before they answer but my first question would be why are you wanting to replace the cam chain but that aside heres a reasonable tip for most of japenese overhead cam fourstrokes.......if you do in fact have a " master link" then remove your valve cover and magneto cover and get your timing marks lined up.Take a picture or make some marks with a sharpie or whatever you need to have a reference point for timing marks. Take 2 pieces of flexible coated wire like some heavy guage speaker wire and cut off prob 5 feet or so twice. Take one piece and loop it around the last roller in front of your link your removing and do the same to the other side. with those two tied off loosely to your frame from above remove your link. So the front side should be suspending the front half of the chain to the frame above and the rear side of the separated chain should be suspended by the other wire. Now join your new chain to the old chain hanging off the front side with your master link. remove all tension from your cam chain tensioner then your ready to do some threading. Lay your new chain off the front of the motor hanging down somewhere it wont be collecting debris. this is where you need an assistant. Have your friend hold the new chain up and off to the front and keep sufficient pressure so slack wont fall inside the motor and jam up then take the back side wire and start slowly with your right hand lifting the backside of the old chain out as your turning your magneto counterclockwise with your left hand. Make sure you and your friend keep sufficient pressure on the chain ends to keep the chain contacting the bottom sprocket. So the rear chain holder is actually pulling the old chain out and turning the whole rotating assembly with the magneto in a delicate dance till the new chain is up out of the rear casing and the friends chain is ready to get sucked into the front end. If its a dual overhead motor then drape the front slack over the front cam sprocket and have friend hold their hand ontop while the rear segment holder removes the old chain then drapes the end of the new chain over the rear sprocket then replace masterlink which should be acheivable if your cam chain tensioner was allthe way out Now reapply chain tension with tensioner and re verify all timing marks. any adjustments can be made right there between cams to line up everything. Buy your friend a 6 pack of suds and and go for a nice ride tomorrow after you and your friend have slept off the celebration 6 packs from last night. good luck

Unless you are changing sprocket sizes you can not shorten the chain because removing even one link would not allow the ends to connect. Are you adjusting the chain as needed? Why do you want to shorten it?
Even if the factory chain has no master link (some are continuous these days) you can still grind off two pins carefully and push out a link to remove the chain, or simply cut it. That is what you must do when replacing the chain.

Your bike should have a master link. Remove the link then remove the chain. Loosen the axle nut and move the wheel forward. Mount the new chain and install the link. Be sure to put the master link clip with the closed end facing the direction of chain travel. Tighten the chain using swing arm index marks then re-tighten the axle.
Go riding!

it could be , find a long screw driver or something like and use it as a stethoscope and with the motor running move it around the engine and listen for the noise location, cam chain , valve lash,clutch etc.

i have change mine with open motor while reparing my transmission and i`m not sure that`s a good idea to change it in place, but if it`s work you will save time. I took about 8 hours to close transmission and motor and take it back in place.

mmmm not sure this is what needs doing, I,E, the cam chain needs to be under tension as the inlet and exhaust cams and crank all turn in unison to drag the chauin through and round, in order to maintain the safe firing sequence!! also I think my tensioner is a automatic one, and cannot be manually adjusted, so maybe let the shop do it for 90 pounds. Also if the plugs are removed the crank can be turned easily, and the chains held together by lock wire, I think the hard bit would be turning the cams and crank all together. would it not be easier to remove the tensioner, then cut the old cam, link the 2 together and let them drop down whilst wired at one end and fed through, surely it cannot be hard to feed it round and thenget it on the crank sprocket, and the reason I want to change the cam chain is it has done 55k mles and is rattling its ti7s off!! Unless you know something I dont about the chains?? thanks mate
