I decided to nix the IMS 3.7 tank on the 300 and go back to the stock tank because of cooling issues. The IMS leaves no room behind the rads for air flow and won't work with the fan I installed today. I love the safe 90 mile range of the big tank but with the extra weight and cooling issues here in the AZ triple digit heat and with the fan I can't use it. Anyone interested shoot me a PM... The 300 will be all back to tip top by next weekend.....I'm having major anxiety not being able to ride it. Need the 2-stroke fix.
