how do i kno if i have a hotcams

[crxjarred]

well when i got my 400 the guy says he didt kno if it had a hotcams in it and was guna buy one and see if it did then take it back if it did but how could i check cus im in the prosses of fixen this thing and i took it down the road once and its hella fast and all i kno thats done is the choke removed and the lids off the box and a k&n filter thanks

i believe hotcams is stamped on the cam. also it will tick louder than most stock 400's

[crxjarred]

ok is there like a cover on the side where i can take off and glance in and would it sould like a valve sticken? like a tick nose cus i beleave i have some of that

your going to have to take your head cover off and get the # on it. thats the only way youll know for sure. but your going to have to find out eventually or else you can never adjust your valves.

[crxjarred]

ok is there guna be a gaskit i have to replace if i take it off

You can also listen to the way the bike starts. Hotcams do not have a auto decompression mechanism which makes the starter spin slower due to the higher compression. The stock cam has a decompressor so the starter will spin quickly. If it doesn't sound like the starter is putting up a fight to get the bike going I would say it is a stock cam. I'm not sure if that makes any sense to you.

yep. the valve covers have to come off to see what came is in there. the gasket on there should be good enough to reuse. i have reused mine tons of time. its a metal one. also if it does leak i would just use some gasket sealer for a quick fix or to do it right get a new one.

[rob_990]

you dont have to take the valve covers off.but the head cover gasket is metal.i had to replace mine cause it had something else in there but if your careful it should be fine.

[Choppers]

ok. he wants to know what cams in there. so i mean i may be stupid but the cover with the rockers is a valve cover right? there isn't anything clear for him to see in there for the cam. so obviously he has to take the cover off to see the cam.

if you send me the cam I would be glad to try it out and let you know if its a hotcam haha. If you dont want to open it up just see if it ticks really loud. If you open it up and the cam doesnt have the decomp. mech. then you know its not stock.

[Choppers]

honestly it doesn't take 15 minutes to see if its a hotcam. plastics off then gas tank and i think 12 bolts and your in then just readjust valves when your done and hopefully you will like what u see.haha

[crxjarred]

so this decompresion thing what should i look for there just a missing lobe on the cam or somethen??

[crxjarred]

ok i went out and took everything off im down the the cover and i have taken all the 8mm bolts out but it wont buge i didnt pull to hard diddnt wana brake anything but is this all the bolts i need to take out for it to come off thanks

[440challenger]

take the 10mm head bolt out of the center of the valve cover

[Choppers]

and the long bars that run through the top of the cover. then if it still doesn't want to come off which is logical since its been on there forever. get a hammer or a rubber mallet if you have one and tap on all 4 corners then it should want to come off. you will lose a little bit of oil but not much. so be ready to catch it with a drain pan or old grease rags.

the valve covers are the 4 things you can take off to adjust the valves.the head cover is the whole top thing with the 4 valve adjuster holes.

[Choppers]

ok well i meant head cover then.lol. i just thought of it as a valve cover cause valves are under it

[ryder_trig]

Since we are on the subject of cams and adjusting the valves, what is the proper valve clearance? Thanks

[rob_990]

is your motor stock?

[crxjarred]

ok got it off but i dont think this is an aftermarket one tho

Yes with the exception of the sparks 6* timing key and a k&n with no lid

[cam19aro86]

Looks after market to me, I don't see the decompression mechanism.

[rob_990]

turn the motor over counter clockwise through the center hole in the middle of the left crankcase with a 17mm sprocket and see if theres any writing on it mine hot cams stamped on it.

[rob_990]

stock valve settings are .10mm intake and .12mm exhaust.

[Choppers]

yea hotcams should be stamped on it somewhere. just keep turning it over until you see it. if you don't see it then it could be another aftermarket cam or stock one.

[crxjarred]

ok ill check this tomaro not enuff light right now buy what other types of cams are there

[crxjarred]

ok i did this and i didnt see anything stamped on it but A and D and i think its just stock o well lol

remember when your putting it back together to adjust your valves and torque everything down right.

[crxjarred]

how do u adjust the valves where and i suposto check for the clearince and where do i adjust them at i kno how do do this on other moters but not on this thanks

[cam19aro86]

Don't torque the cam cover bolts to the 10 ft. lbs. the manual says. They snap and could be a nightmare for you. Just tighten them down snug and call it good it won't leak.

[rob_990]

theres 4 caps on the head cover you take off and its right under there.then you lossen the locknut a little with a wrench and decrease increase valve clearance with a screwdriver.your going to have to get a feeler gauge and put it between the subrocker arm and the adjusting screw.get it so it fits snug. then tighten the locknut. just make sure its at tdc and you should be good.
