450 R Timing Chain

[REESE]

I READ ON HERE OF GUYS USING A 450 R TIMING CHAIN IN PLACE OF THE STOCK 400 EX CHAIN. I BOUGHT THE 450 CHAIN AND IT IS TWO LINKS LARGER THAN THE 400 EX CHAIN SO MY TENSIONER WILL NOT TAKE UP THAT MUCH SLACK

DOES ANYONE KNOW IF A DIFFERENT TENSIONER OR A DIFFERENT CHAIN GUIDE IS NEEDED TO USE THIS CHAIN? I WOULD APPRECIATE ANYONES INPUT AS THIS IS HOLDING ME UP ON FINISHING THIS THING.

:mad:

the (dirtbike) 2002 crf450 timing chain is the one that fits in the 400ex. It has the same number of links and is much beefier. I just installed one on my 400ex and it works great.
