First time running #219 chain and was wondering is there a limit to how many times the chain can be safely opened/closed or length adjusted assuming proper installation and maintenance. RK Gold with no master link on a 4-stroke.
Not sure of your answer but why do you run a 219 chain? Most 4 stroke guys run 35 chain and a split sprocket due to them being inboard of the axle bearings. The 35 chain uses a master link so you would not weaken the chain by pressing it apart. 219 chains seem to be popular with the 2 stroke crowd who run out board sprockets and chains being that they don’t have to take them apart to remove them from the kart and therefor don’t need a master link.
I am running 219 for clearance between the rear sprocket and rear cross rail on my new frame. (Smaller chain and smaller diameter sprockets) On my old frame I had more clearance and had no issues running #35 chain. I am using split sprockets inboard.
I just didn’t know if it was acceptable to add/remove links as needed or if it would be better to just make seperate lengths of chain for each ratio combo.
I my self do use 219 chain on my 4 stroke. We had custom clutch sprockets made and cut the frame so we could run a bigger gear on the axel. Split sprocket too. I did this so I could trade gears and chain with my kt100 that way I didn’t have two sets of every thing. Why not run 219 on a 4 stroke since it’ll keep up with a 2 stroke.
No offence Walt but if you break a chain you through it in the trash as it is stretched and damaged. I have raced motorcycles most of my life in the dirt and the street some with over 100HP and have never broken a master link. So I cant imagine a 10hp B&S engine being to hard on a master link.
