I want to lose my airbox, when I bought my tidy tail I also bought a throttle body clocking flange. I want to point the throttle body forward and have a short tube heading up a few inches with some room to have a mount for the intake air temp sensor.

Pros, more air less weight.
Cons, need to buy an exhaust too and eventually a efi controller / programmer.

 

already have yosh exhaust no efi controller

 

Brian S will be doing some research on stock airbox flow soon. I'm tuning in for his reports.

 

my question is will the fuek injection make up for the big change in air volume and will it run good/better.

 

anyone have any input on this

 

talked to a few mechanics today at fox powersports. with filter and exhaust bike will run too lean. im waiting til I get a fuel controller

 

I haven't done anything to the air box and although I prefer a washable, reusable filter, I didn't even go there because the oem filter is really cheap...under $10.

I don't race either, but I always wondered how safe it is for the engine to ride above redline? When I look down and see I am over redline, I slow down (or switch gears) although I see people on race tracks riding well above redline. If you do mods to get additional performance out of the Grom, don't you have to reset the rev. limiter too? I already hit redline easily with my stock Grom, so I have been reluctant to try and get more speed out of it. What is the risk to the engine of riding say 70 mph consistently with a modified Grom? I know nobody can say for sure, but what is your estimate on engine/valve life?
