Yes its a 420, about 84 links.
Do you need a bigger chain for the 18 tooth? I know it is much rarer to need to cut or add size when you change a front sprocket, but then again, you have a brand new chain. I hope the weather can break for you to get a little ride :riding: , although you still have that wrist injury to deal with :eek2:
The old chain was 84 links long and was about. 5mm too short after fitting the 18 tooth. I wanted to fit a new chain as the old one was worn and running tight and slack. I was going to make the new chain the same length then take up the slack by adjusting the rear wheel.
I have to return to the hospital to have my fraactures reviewed on the 3rd of December, so am hoping the cast will come off ten. I have tried operating the controls with the cast on and can manage ok, but my wife would kill me if she caught me out on the bike. She has banned me from driving my jeep at the moment too. So i am having to get rudes or taxis to get into work at the moment.
Its dry and sunny here today so thought i would take her out for a little test run, the wife is at work all day :-)
The chain is fouling the front sprocket cover by a millimetre or two. Have filled it down as well, took it for another run but the back end felt squirmy, so have come home. Will check the rear wheel alignment tomorrow and try again, the wife is working all day tomorrow too.
You know if you are caught by your 'mum', she won't let you play with us anymore!?
Lol, you are probably right. Both sons knew i went out, one even said ' if mum finds out she'll go mad' May have to buy them take away for dinner to buy their silence.
I managed to fit the new chain this morning despite not being able to locate my splitter. Took the Lifan out for a shake down run, which became a speed run on the local by-pass. Less than ideal conditions today with a bit of a head wind and dithering car drivers. I managed to reach 56.5 mph, a slight improvement on last time with the 17 tooth sprocket. I think i need a longer stretch of road to get the best out of her, she felt as if she had a few more mph to give but it may have to wait until spring.
The other part of it is how many fewer revs the engine has to make--probably, like most Chinese enduros, there is not a tach to gauge this, but it is a consideration--slightly higher top speed + less engine stress = happier Chinabike!!
Yes its definitely running at lower revs.
What's your rear sprocket?
Also I bet your exhaust is restrictive with a cat in it.
