what kind of oil are you supposed to run in these transmissions? i did a search and some people are saying 10w 30,some are saying use 10w 40,,and some are saying to use 80w gear oil,and even 90w? right now i have castrol gtx 10w 30 in mine,and am having no problems,by the way,i need to know how much as well

 

Get the Belray Gearsaver from your local neighborhood quad dealer. That stuff works awesome, about $5/quart but worth it. I can't remember the oil weight though.

 

Honda HP Trans Oil

 

yeah i know theres lot of stuff i CAN use,but i was wandering if car oil will hurt it

 

The std 10w30 or 10w40 will not hurt anything, as that is what the manufacturer intended to be ran in the gearbox.
Things have progressed with oil technology thru the years, and the above mentioned gear box oil is probably a good idea. (I run the Bel-Ray stuff myself)
The biggest benefit is that it doesn't need changes quite so often.

Just watch the synthetic motor oils in the gearbox... (Mobil1, ams, etc.) I've had problems with clutch slippage. These oils need a friction modifier to work with a wet clutch.

Regards,

 

I've ran both regular car oil, and the gearsaver. I can feel a difference, however both will work well. As Duneaddict stated, the trann and clutch were designed for good ole dino grease.

 

thanks,she runs strong as heck,she should though the whole engine is fresh

 

Read this great article:<a href="http://www.thumperfaq.com/oil.htm">

Car oil is the last thing you want to run in something with a wet clutch. It's not even that great for your car! From the article: "Do not use automotive motor or gear oil in the CRF transmission [or your 2-stroke transmission]. If the gear oil label doesn't have the word "twostroke gear oil," "safe to use in wet clutches," or the API SG or JASO MA designation, don't use it."

You can run any API SG or JASO MA oil in your 2-stroke transmission, but why? All these "wet clutch compatible" oils are a COMPROMISE for 4-strokes where the engine and transmission share the same oil (a really dumb idea!). Your quadracer is a 2-stroke, so you are one of the lucky ones (along with us Honda TRX450R and CRF 4-stroke owners!), who can actually run a transmission specific oil in the transmission.

Honda HP Trans Oil is 80W/85W (but it isn't thick like car gear oil!). The one exception would be that if I lived in very cold country, I would run a lighter JASO MA oil in a 2-stroke transmission, during winter.

Another (4-stroke) motorcycle oil atricle. Probably more than you wanted to know:

Well I use 10w40. Been using it since 93 when I bought mine ... Gears still look great. On my second clutch since I bought it. First of all automotive oil is way better than it used to be. Car engines today get many more miles out of them today than ever... and they run HOTTER due to emissions. So the oil has to work better to keep them from siezing up. Rings and valves last longer due to the lube they get. I change my oil often. Usually every couple of rides unless I have been through water. These machines were designed back in there time for use with motor oil and recomends it in the factory service manual. I usually just pick up a case at Costco and go with that. I like to chage it often as the cleaner the better. Even expensive oil still gets dirty. Most auto oil brands don't really have much difference between them for me to bother with except for synthetic...That is all I use for my cars as it is not economically feasable to change your car oil every other drive. Plus you want the extra slippereyness that they give as you do not have a wet clutch to worry about which needs the friction to work. Man talk about a double edged sward. I get the cheap stuff for the quad since I do change it often. That's the real key to making it last. So to answer your question you will be fine for with running with a quart of 10w40. Get in the habbit of changing it and your bike will thank you for it

 

As far as the amount, isn't there a check bolt on the side? Just put some in until it comes out the check bolt hole. It might even say on the case near the fill hole, what the volume is. (Haven't looked closely at a Quadracer in years).

Using car oil is NUTS. Sure, somebody might get away with it, but read the articles, it is really crappy stuff, and to slick for a wet clutch! If you insist on using it, don't use any of the "energy conserving" ones.

If you don't want to use the trans oil I suggested, I would use 10W-40 Honda HP4 oil, without moly. It is a JASO MA synth/petrolium blend.
