Just purchased my Grom and already want to make it go faster, but still want it reliable to drive to work and back everyday. Any suggestions exhaust, air filters...

Thanks

So many exhaust options I still cant decide myself! Heres a few on hardracing.com http://store.hardracing.com/cart.php?target=category&category_id=2503

13t front sprocket

Sprocket change does give you a greater pickup and go on the low end but your speedo indicator will be off depending how many teeth you went down or up on the front sprocket "counter sprocket" or the rear sprocket that is on the wheel.

GPS is one of the few ways to get a accurate read out of mph.

What is top speed with a 13t? 65 at 9500 rpm?

Op: right now you're best mod is MILES these bikes loosen up a lot over the first 1500 miles or so, then look into intake pipes, there is a very inexpensive setup explained in my build thread, the filter can be found on eBay for 7-8$ and the exhaust is your choice.. Some better than others but they all are better than stock

He said he wanted power for little money. $7 sprocket will give him more power/torque

 

[Strokd_GE]

He also asked about making it "go faster" and lowering the gearing won't do that nor will it give you more power, however a good intake and exhaust will.. Also again, mileage plays a big role, my bike new would struggle to do low 60s in a tuck, after 1500 miles or so I could hit 70

Thanks for all responses. Looking more into exhaust/air filter recommendations.... Which ones have better performance than others? Will look into sprocket change once I gain a little more HP. (I know sprocket would be the cheapest to go faster)I will most likely keep it stock for the first 1K miles.

Yoshimura and tyga seem to be quality systems. I would go with the MNNTHBX exhaust personally.

Chimera and btx are the two intakes I know of, or just putting a K&N filter on the TB.

You can also do mods to the stock airbox to help, there are videos on youtube on how to do it.

I just got a BIG GUN full exhaust for $245 off ebay.. I like the looks, love the sound and REALLY loved the price... It was a no-brainer. And I got about 3-4 more MPH on top end and a little more power on bottom..

guys look around, i got my full yoshi exhaust for the price of slip ons, and i got this last year right when they came out, not full carbon the aluminum with carbon tip

That's one helluva sentence.

Did the air box mod and just bought a two brothers exhaust, we'll see it that hits 55mph fast enough for me. I live on Maui so max speed is 55mph on the fastest road.

(I never got my motor cycle license yet so I have to stay with in speed limits… Lol)

Like everyone said, do all of the diy that are free first.

And start shedding weight off the bike.

As Stroked GE outlined in his build thread with the radiator hose mod to the airbox, I know this is the best bang for buck mod you can do. Yes, other intake mods will get you more speed also, but they will cost more $$$ than the $12.00 I spent to do this mod. You will be pleasantly surprised with the 3-5 mph gains. This is my only performance mod and I can get 70 mph from my Grom regularly with stock exhaust. As he stated, putting some miles on it will help also as mine seemed to loosen up alot after 1000 miles. I like the stock 15 tooth for overall riding as the speedo is still spot on. I recommend spending money on an o-ring chain to get longer life from stock sprockets as my standard stock chain was noticeably worn after 1200 miles and needed numerous adjustments before I replaced it.
