Please give me any advise you can. im thinking its possibly a head gasket if so let me know how to fix this prob. Thanks

 

i would not ride it anymore until you check it out. check the complete cooling system... water pump, t-stat, radiator. does fan turn on? is it blowing white smoke (anti-freeze) from tail pipe?if so you have a bad head gasket. does the oil look "milky" (anti-freeze in oil)? do the spark plugs look real white or have a greenish tint to them? these are also signs of a bad head gasket.i have seen engines that are starting to seize or go bad, turn off when really hot (bearings starting to seize etc) then when cooled off will start again, but when hot (expansion occurs) will shut off or finally blow up!

 

there was a thread about 636 cooling issues in vegas. this was 3 or 4 days ago. check around for that thread and read in there. tons of people responded with tons of help.

as for your question, we need more details...all bikes get hot so that's a vague statement. you haven't given us a reason why you think it's a head gasket. head gaskets can be blown and it not even overheat....so that doesn't really mean anything.

 

Wont start once its hot smells like coolant and not leaking any or overheated plus my friend had this happen to him and im not sure how to even change this or repair the problem if its even whats wrong thanks for any advise. more advise the better. if anyone knows anything please help Thanks

 

have you checked your coolant level? a little drop of coolant on a radiator can smell like coolant. make sure your level isn't dropping.

what about the heat, what temps, what are you doing when this temp changes, how long does it take....

also, here is the thread, it's on page 6 of this forum (stunt discussion); it was discussed 4 days ago.

The link didnt work

 

i just clicked on it, linked worked fine for me.

and it's on the 6th page of this forum, go to it, (636 overheat issues). please don't become helpless on us now.....you'll get a lot of answers from that thread. i helped by posting a link, i won't copy and paste the whole thread.

 

yea my bikes running dumb hot...it wont drop under 205 on the street even in 6th gear and when its cool out.,,,cool out i mean 50s ....??? any ideas...
i just changed the oil......plugs are good...i really dont want my motor to blow.....

 

Thats not helping becouse my bike wont even kick over when its hot i was told it could be the head gasket how do i fix this i caant afford a new motor or any down time

 

I know some one on here has had this problem how do i fix this. Thanks for the help bender

 

I don't see the head gasket causing it simply not to start once hot. I would assume its more internal then that. The gasket would cause it to heat up quickly, also build a lot of pressure in your coolant system.(meaning your bike will "pee" out of the vent tube).

Here is some questions to help out with the problem though. Does your bike quickly over heat? With in a few min? Once it gets to 240+ will it shut off the bike? When the bike runs does it ran as it always had or seem lagy and slugish? Do you notice any smoke while idle or while riding? All these can help point to a problem. Once the problem is found then we can help find the solution.

Or, change oil/plugs/flush system and run some of the antifreeze options mentioned in the other thread. Then see what happens.

 

Also, while the bike is down do the Kleen air mod if you have not done it already..

 

Can someone post up how to swap gaskets please thank you

 

cbrforum.com tons of info and you get down loadable pdf files for your bike.

Just look around a bit....or google what you want..most time its that easy.

 

ok this is what my bike does...
1 start it up..
2..wait a couple of min
3..start riding down the street
4..2 blocks later my bike is at 215....
5..me yelling what the ****..
6..go down the back road 6th gear at 5 grand going slow..and its 50 degrees out and bike still 205-225

most of the day its near 225-230


what the hell
any ideas

 

Flush your radiator and wire your fan

 

Check your fluid level. Put your fan a switch for all the time with the key, change oil, check thermostat, and flush the system and run one of the coolant options posted in the linked thread. If the problem persists check for clogs in your coolant system including water pump. If that checks out fine then your down to your head gasket. I don't think I missed anything.

 

ok ive noticed that antifreeze leaks out , some where from or by the ressy,,and fluid dripping out of the line out the bottom

 

That means you have built up pressure from over heating. You are more then likely getting blow-by through the rings. However, it could just be the pressure from the temp you are running at. So try all other cheaper options first.

There should not be any leaking out by the ressy though..check for holes.

 

ok....
i already changed the oil,plugs,,and flushed the rad,not sure if i did that right but....


still does it...so what should i do now..
