Anybody add a master link and a extra link to
the chain to make the wheelbase a tad longer
to help stability on top speed.
The stock chain a KZO 520 doesn't have a master link at all. Whats up with that.?
but has anybody tried this (adding link) and
did it help. Thanks Tom

i have thought about doing it since i got the bike. i think i'm gonna do it before the MX race we are putting on. i think the bike would be a lot more jump worthy with a longer wheelbase.

Well guys I added 3 links or a toatl of 115
stock is 112. and the headshake at top speed
is gone. it feels a little nervous once in a while but alot better than stock, still playing with the main jet, up to a 172 from a 165, seems a tad sluggish of bottom but roars
on top.might go to a 13 tooth. next
