Does anybody know if the stock shrouds will fit with the acerbis 3.3 gallon tank or do you have to buy YZ shrouds? Thanks

What year stock shrouds?

WR400/426/450 Frequently Asked Questions

Q: I need a bigger gas tank! What are my options?

A: IMS , Clarke and Acerbis are the three big names for aftermarket fuel tanks. They will bump up your capacity to 3.1-3.3 gallons depending on brand, though there are both intermediate and ginormous sizes as well. Furthermore, unless you have an '05/'06, you will likely need to buy YZ shrouds to fit the tank, as the WR versions don't line up.

Q: Will YZ plastics work?

A: Yes and No. The fenders generally will interchange with minor trimming on the rear to accommodate the coolant reservoir. The side covers are different, as the WR has the quick access air filter panel, but some members have been able to use YZ side covers with a little creative tweaking. The radiator shrouds are interchangeable with the 05 YZ on the 05 and 06 WR, but not on earlier years. As updates usually hit the YZ first, it is usually a good idea to buy plastics from a YZ a year older than the WR you’re mounting them on.

I have an 05 wr450 which is exactly the same shrouds as the 06. Just last month I put an acerbix 3.3 gallon tank on and my existing shrouds fit just fine. You will have no problems.

I have an 05 and my shrouds fit OK with just a little bit of shaving the plastic rib. Just bend the shroud to make it fit and locktite it!
