Hey everyone I put on the 520 -1/+2 and I gotta say..it makes a big difference. I would recommend it. I think I am going to get the PCIII ignition mod and have the local shop tune it. I need the speedo healer, is there anywhere cheaper then $90? Thanks in advance.

 

I wouldnt say you needed the 520. Maybe just getting the -1+2 sprockets would have made you happy

 

yea i agree with dt...it's not the 520 you are noticing but a BIG majority the -1/+2
you'll just notice the 520 when it's time to change the chain and it's only been like 7K miles...hahahhah...

i haven't seen speedohealers go from cheaper than around $90...unless you buy used.

 

When folks say -1/+2 they mean -1 on front and +2 on rear right? What's stock?

That configuration produces quicker acceleration in exchange for more gear changing and lower top end, right?

 

yes you are correct.
stock depends on which bike you have...

 

stock f4i is 16/46

 

I ordered mine at motomummy.com for like $82 with shipping a and the quick connect adaptor. Fast shipping, great customer service. The speedohealer was dead on, easy to install and easy to program.

 

Why?

 

it's probably too jerky now

 

The PCIIIusb Ingnition Module won't help with that. Just getting a good fuel map on the PCIII will take care of that issue.
