For anyone thats coastered.......

I ordered a coaster-kit from shermscycleproducts.com, nice kit but the vacuum hose plug/removal directions for the CA version bikes was somewhat 'generic'. I decided to call them yesterday (spoke with a dude named Guy, very knowledgable) to get some clarification and picked up some tips that maybe of value to some of you that have also coastered as follows.

1. The CA version has 2 tank vents (instead of 1 for the 49 state-blue only) 'blue-left and red-right'. After removal of the charcoal canister and seperator or 'pump' as kawa calls it, you need to plug the red-right line and leave the blue-left open. This is necessary to prevent fuel seepage after fillup AND fuel starvation under load.

2. Their is a 3rd large vacumm line from the air-switch under the seat (all models) diameter the size of your thumb that terminates into the 'duct'. This needs to be plugged or you will pull unfiltered air into the system and run lean.

3. After the gutting of all of my hardware/plumbing their was an additional smaller line running into the duct that also need to be capped or again you will pull unfilter air and run leaner.

4. Guy at Sherms also recommended to bump the idle up to 1250-1300 rpm to lean the idle mix abit as you will richen up if all lines to duct are properly capped. He also said that no rejetting should be necessary unless you install an aftermarket exhaust system or do an ear shave.

After the coaster install/Un-CA'n of my bike I have NO poping on decel and the incredibly annoying rattling of my airswitch at around 4-grand is distant memory. IMO, the information and assistance from sherms alone was worth the $23 I spent for the kit.
