Has any1 experince this b4,once u fully close the throttle the engine break dont feel smooth,like jerking and with each sudden jerk there soft 'pop" sound coming out from the exhaust.It always happen to me,in any gear,but the most obvious is in gear 3 or 4 with 5~6rpm.But when i 1st got it the bike,it was't liek this.Btw am running a LV full system with PC3 and mapped.

Here you can see the bottom part of the chain is easily touching the bottom part of the chainstay.


So what do you all suggest?

I don't recall off the top of my head, but I'm pretty sure my chain won't touch the swingarm/chainstay when adjusted correctly. It seems to me like you have WAYYY too much slack in your chain.

just went and checked my chain the same way you did. Mine is really loose and in bad need of adjustment, and it BARELY touches the the swingarm right at the pivot point. I think your chain is seriously out of adjustment. The proper chain slack is indicated on the stickers you can see in your pics. Measure it and see how close it is.

Yea, that chain shouldn't be able to touch the bottom of the swing arm. I believe it's supposed to have 1 inch of play total (1/2 inch in either direction). If you can push it up to the swing arm, you probably have an easy 2 inches + of play.

I don't think it's that bad.. mine is out by about 1/2" and it can touch.. barely. but yeah, his is definitely out of spec.

you have the shop tighten it??? loosen your axle nut and unscrew the two bolts that are touching the axle blocks on either side... and done.

Be sure to check your chain while seated on the bike too. Makes a difference and having the chain too tight can bind the rear suspension causing all kinds of odd behavior,

Can I ask if you have any other mods besides the power commander and the map with the full exhaust? I did a pair mod, slip on and air filter and until the PCIII was properly mapped it did this too. Now it runs like a dream....

The guy that does all the suspension tuning in some show (i dont remeber who it is, but he goes to track days and charges $20 for a basic set up). He said the general rule of chain slack is you should be able to touch your swing arm with the chain.

Maybe two clicks out? Or something like that.

koxie i think your mechanic is right.

chain needs 1-3/8" slack.

these bikes do not like that zone of 5-7 krpm and i have found that i need to be very gentle with rolling on throttle in certain situations.

have full arrow exh and pc5 and have learned to ride in a higher rpm range.

True, however the chain slack is specified with the bike on its side stand and no-one on it... removes that variable...
