Interesting that you lost TQ from the intake and he didn't, nice results though!

BiG Chris · Mar 6, 2014

nice numbers

So either the Yoshi pipe is THAT good or the SUS has a hard time breathing through all that curved pipe.. Cool none the less and 10.5 is good stuff

Awesome numbers! Just put my Chimera intake on today, and can't wait to see what it does with the FMF full system.

So we are looking at $500 or so for 1.5 hp or so gain?

LOL

Not judging as I too have the steady garage intake and a DG exhaust.

That is so true. YEARS ago my buddy had a CB750 and I had a stock CB900. He put hundreds of dollars into exhaust and smoothbore carbs and I could still smoke him.

But small CCs is what the Grom is all about. It is more fun to ride a slow bike fast than to ride a fast bike slow. And with this intake and exhaust I at least "feel" like I am going faster.

Wonder if the 2200 miles had anything to do with the better performance. Engine was probably not completely broken in at the 300 mile Mark. Was this same bike?

Thanks for the post!

2 different bikes. A couple of my friends and the guys at the shop speculate that it could be either the bike not being broken in yet, or that the yamamoto just has too many bends. Personally I have no idea, maybe some one with more knowledge can make it rain.

Were any of these bikes tuned or just parts installed and dynoed?

No bikes were tuned. only mod we did besides exhaust was airbox mod. besides my bike, they all have around 2000miles. Just installed and dyno'd.

I believe they are the Over racing rims.

What was the afr on each bike after the intake and pipes were installed?

We didn't look at the AFR, next time we dyno, I'll keep a lookout for the air fuel ratio. I think steadygarage might have saved our files so I might be able to post pics. I'll let you know.
