Help?

[DZircher]

Well I brought the bike out into the sunlight today and start her for the time since I started this build



Looks awesom but I think I have a vaccum leak cause it run rough around 4500 rpm. I think I may have done the emissions canister removal wrong. Any advice will be greatly appreciated.

Did you ever get it dynoed and mapped?

No, not yet. I figured it should be running better than this though. It's been a rough couple of months at work and I haven't been able to get away. I guess I've got some calls to make. Thanks smutty!

Whats involved in this? Just swapping the exhaust or going after stuff on the motor?

Any lines going to the airbox/intakes that were involved with the evap canister should be plugged. If you pulled the lines, plug the ports.

Mostly just the exhaust but I did remove the emission canister and replaced it with a sealed overflow container. I'll need to check my work. Maybe having a closed loop in the fuel overspill is causing a problem too.

Thanks, I believe that I did this but my guess is I screwed at least one of them up.

Your overflow container should have a vent line. Preferably long and down to the belly pan. Sounds counter intuitive to vent a catch bottle... but when you've got lines expecting to see atmospheric pressure and instead are getting vacuum or high pressure it can muddle things up.

Do you have grilles in your air intake? I not you might have a mouse nest in one of the intakes.

I think this is likely the problem, the only vent was the drain valve which is closed. I plan on testing this theory later this week when it's not raining and I can get her outside without falling on my butt. I'm also bringing the bike to my dealer next week to have them check all my wrenching to make sure that I don't find the problem myself in turn 1.

Thanks for all the advice everyone!

The bike looks gorgeous. A dyno session before you ride will ensure that everything is right. Make sure to scratch before heading out on track...

[Kurlon]

Paul... you should totally buy CEO's 'tard, and then a garage spot from DZircher... it's almost as if the universe is aligning to allow you to make a comeback?

If the universe also rains down cash it will be the final sign.

Well, I just happen to be home sick today so I decided to open the petcock on the overflow bottle, stick the ass end of the bike out the french doors of my house and start it. A quick survey under throttle and it seems like that indeed did the trick. Looks like I'll need to add another vent line as was suggested and run it down to the lower catch pan I guess.

Once again, thanks for the advice everyone! I'm still bringing her into the mechanic that worked on my Monster to let him check my work. Can't believe that the the first NHMS weekend is approaching so fast.

Niiiiiice. I'm extra paranoid, if there is any chance those vent lines can breathe in, I like to put a filter on the vent. I'm crazy like that though.

Well, that's one less sick day you'll have for riding. Feel better after fixing the bike?

[DZircher]

Funny but yeah - it was a load off of my mind for sure.

If you do it, you know I'm going to have to do it. Don't put me in this position man!
