What does everyone use for oil weight in there stunt bikes???

 

i always use mobil 1 racing 4t 10w-40 fully synthetic...buy it by the case on sale but regardless, that ****'s expensive

but i've never had any motor problems and i have 20K miles of stunting on my f4i (have oil pickup)...i just change oil and filter every few thousand

 

20W-50 HONDA GN-4 EVERY 1500 miles !

 

20 50 golden spectro semi synthetic

 

AmsOil 20W50

 

maxima premium 20-50

 

Ever time the difference between building pressure on manufacturers recommended 10-40 vs 20-50?


I did test the difference between 10-40 nad 15-40 on my f4i and my 1990 honda prelude, both took ALMOST twice as long to build pressure!

I did run rotella for a good 5-8k or so on my f4i, but now run either super tech or mobile clean 5000 10-30 or 10-40 depending on season in my f4i, WELL over 35k on my motor, stock clutch, still running strong as hell


edit: btw if you don't know what I mean by my post, I'm saying, there is NO reason to run 20-50 unless you ONLY start your bike when its 90f+ out, and NEVER let it cool down. Bike manufacturers aren't brain dead, they didn't say run 10-40 because they are clueless as to what actually works, they have some sort of idea as to what's going on.

 

i have been running 10-40 but recently switched to 20-50 due to taking my head apart and seeing the wear on the cams from the bike running at 220+ constantly, kawi mechanic told me to run 20-50 for a few months, then we took the head back apart and there was 0 wear on the new cams... to each there own, but i will never run anything other than 20-50 semi syn, from now on.

 

220 constantly? Have you tried fixing your over heating issue or you do you just run it at 220 and run too thick of an oil as band-aid?

You shouldn't be at 220 unless you run on rev limiter constantly, donig burnouts, revl imiter coasters, or anything high rpm for extended periods of time

still would be weird for most the time your bike running to be Above 220... Not sure my f4i gets above 220f for more then 1-4 hours a YEAR out of riding 10kish miles a year

On a side note, how many miles were on the cams before you removed them the first time?
How many miles on the second set of cams?

And why were the cams removed the first and second time, why have you been through two motors? And were the cams even damaged or just 'worn' and replaced without actually failing?

edit: also if your kawi is spitting cams in less then 30k, then maybe its a kawi problem and not a oil problem?
I mean, since whats kawi recommend, 10-40 oil? Why would that cause wear?

 

castrol 10-40w moto

if they made straight weight (30w) moto oil I would run that (sure they do, just never seen it)

 

20-50 my zx runs 218-224 from day 1 unless on the highway then lower.

 

easy towlie no need to get pissed about him running 20 50 lol. he has proly been been thru 2 motors cus he has a new bike and people are still figurin out what they gota do to keep em running right and keep em together. i was told 20 50 by several people and i have had good luck with it.

 

in florida its normal for kawi's to run 220 unless you have 2 fans, there have been a few colder( like 60 degrees lol) days this year where my bike has run 190-200. mine runs between 214-224 with the fan hardwired, only time it gets hotter is when i forget to turn my fan on. my f4i i never knew the temp because i didnt have gauges but it was fine aslong as it wasnt pissing coolant.

 

amsoil full synthetic 10w 40

 

i think all Kawis run 200-225 regularly and especially for parking lot stuntin. i've heard the same from a ton of people. 10w 40 Amsoil synthetic here

 

i'd say 10-40 unless your in a hot climate eg.80+

20-50 for the north in anything but the summer is a tickfest for the first few minutes.

 

both my f4Is always run at like 230 when stuntin

 

15/50 300v motul all the way!!!!

 

do you have your fans set to run? If not, well the stock fan doesn't come on tell 227ish, so of course it'll run at that temp.


But I guess you all can run 20-50 if you wish. I'll run something close to what the manufacturer recommends



edit: just remember, cold start up is very hard on motors..

 

even being a vtwin i run castrol synthetic blend 5w 30 car oil......as long and well as my bike has lasted its great
