does the other modder have the same version DQ as yours? wouldn't be surprised if the frame measurements were off by a hair. razor tolerances are on the low side imo...
PFS has the half link for your chain:

Thank you ZR, order placed for half link...hopefully that does not become the weak link and blow the chain out. The other modder XCNTRK, had an older model DQ....very good point, as that may be all the difference.

This make the angle of the chain to the front sprocket larger. It worked fine really tight. If it really bothers you the pull the motor and enlarge or elongate the mounting holes to allow it to be slid back or forward a little bit. It will buy you a little but letting the motor slide towards the rear sprocket will make the angle even larger.
Thanks Codeman, other modder was XCNTRK, but I remember you did the same mod too. I wasn't sure if you used the same T8F chain as other modder did. I was not sure what the (ideal chain tightness) was supposed to be when a chain tensioner is involved, but I remembered the stock setup being looser, but not loose enough to remove the chain (with spring tensioner disengaged). When I tried the first number of links on the motor/sprocket, the chain easily fell off without spring tensioner engaged. When I removed 1 full link, the tightness felt reasonable with some play, until I connected the spring tensioner, the spring was adding a lot of pressure, making the chain feel unreasonable, and a little difficult to spin the axle freely. I think you hit the nail on the head with the wider stance the new sprocket takes, as it also causes the spring from the tensioner to be stretched further. I was just surprised at the huge swing in either direction with the difference only being 1 full link. I will try the half link scenario, and if that doesn't work, just try the tighter full link, and possibly find a weaker spring for tensioner.
Thank you for your help...
