sounds like it maybe running rich. Do you smell fuel in the exhaust? What elevation are you riding at? Stock jets for the midwest are way too rich for a stock bike in places like here in Colorado.

YAY a 660 question!!!!  :nod:


does it sputter and pop when you mash the throttle?

Or...does it sputter for a sec, then take off fine?

Or does it stay really really bogged down through all rpms with throttle open....?

carb rebuild...? hmmmm check to see both bowls are filling... stuck float? you could be starving it. Stuck choke...?

stock jets should be fine...

there is always that off chance the good ole parking brake or clutch sensor is shorted too.... my favorite. cuts timing above 2000 rpm and makes you think you have a fuel problem.

think it could be a spark issue?
Title: Re: 660 raptor problem please help
Post by: Peelz on March 07, 2012, 03:22:37 PM
yes....very well could be.

no chance this bike was rolled is there?

I say that, because the parking brake sensor likes to break and cut revs....happened to me. disconnect that sucker.

follow the wire from the parking brake down underneath the grill til you find the connector. just unplug it. It's a Long shot, but it's an easy one to scratch off the list....

could check for bad spark plug wire... Ive seen them with insulation gone and shorting out...

grasping at straws with you....
Title: Re: 660 raptor problem please help
Post by: aaron on March 07, 2012, 10:25:18 PM
ive tryd new plug wire already.wen i do a compression test it reads 120 but give it some throttle and will read 180 pis is that normal?
Title: Re: 660 raptor problem please help
Post by: als660r on March 08, 2012, 07:19:58 AM
yes   comp test should be done with throttle wide open to let air in the engine.
Title: Re: 660 raptor problem please help
Post by: aaron on March 08, 2012, 07:39:56 AM
thats what i figured..if it had a burnt valve it would have low compression right?,only thing i havnt really tryed yet with the carb is measuring the fuel level in the bowl not too sure on how to do that but wen go to drain the carbs it doese have quite a bit in them.i did try a other cdi that i had but it had started smokin and then lil pop and put hole out back of it didnt even have the key turned on or nothing was in a other bike that had put out spark but didnt have it runnin were bike was blown and didnt blow the cdi unit like it did wen i pluged it in to the bike i have now,wen it blew the other cdi i had put my other one the one that came with the bike i have now back on and didnt seem to blow it up like it did to the other one,not too sure what would have happend there,dont wanna buy a new cdi unit and plug it in and it fry it like the last one if i do end buyin a new one to see if thats what it is,ive tryed for hours adjusting the carbs and it seems to run best at about 5 turns each or so,all stock jets and have the needle set at third clip.

I've seen the carb diaphrams rip and cause chaos, might want to look at those quick?
Title: Re: 660 raptor problem please help
Post by: Peelz on March 08, 2012, 08:24:57 AM
fairly certain you don't have a burnt valve. your problems would be worse...

+1 on checking the bowls. THat was my first thought, since you just rebuilt the carb.

Reason I say that: I had the 660 float get stuck up , and once down...fuel dripping out the side...easy thing to check.

New CDI was "smoking"? that sounds bad. May have stator problems.
Title: Re: 660 raptor problem please help
Post by: aaron on March 08, 2012, 08:50:14 AM
ive tryed different diaghrams thinking that that may be it as well but no differnce and as well it charges the batt fine and ive tryed a different stator as well,
how do you check the fuel level in the carbs?

went and worked on the bike installed new ring and had cleaned the valves put back togethor.
timing chain had droped down so had to pull the wheel and line the dot on cog that the chain sits on to the the arrow on the casing
put back togethor and timed the cam,adjusted the valves and now is not starting will only start for a quick second then die seems like it is back firing out of carb
Title: Re: 660 raptor problem please help
Post by: Peelz on March 19, 2012, 09:21:00 AM
ouch.

that sounds like bad timing
Title: Re: 660 raptor problem please help
Post by: aaron on March 19, 2012, 10:31:09 AM
yeh wen timing it just tdc and then allighn the cam up for timing right? if so it is timed right any sugestions?
Title: Re: 660 raptor problem please help
Post by: aaron on March 21, 2012, 04:18:56 PM
checked the timing multiple times and seems to be timed but still not starting up i have no idea on wut it could be,
started right before i took it aprt to put new rings in it and clean the valves up.
