Pullstart 62,803 #1 Posted March 21, 2021 @tom2p @SylvanLakeWH @Achto @Oldskool and anyone else in the dirt bike knowledge realm... I picked up a Kawasaki KX65 2 stroke yesterday. It was a few hundred under “the going rate” with a brand new tire and well maintained and I figured it would move quick so I jumped on it. Well, it sure is quick! For the same frame and body as the 110 4 stroke we have in the shop, it is amazingly fast! We did some clutch practice last night and had our first wheelie walk too! She was able to let off fast enough that it came back down with no spill. Nothing but excitement and a couple tears of joy from that kid! The p.o. Used Klotz because it makes less smoke and he likes the smell. I do as well. Nothing like a bike smelling like a pie! Is there any performance / engine longevity difference between kawilube or yamalube or whatever? I have some of that already and am having a hard time finding Klotz locally and it’s quite low on fuel. 1 Share this post Link to post Share on other sites
Pullstart 62,803 #2 Posted March 21, 2021 @chucksterock I saw your Klotz reference, figured I’d pull you in here too. Share this post Link to post Share on other sites
SylvanLakeWH 25,494 #3 Posted March 21, 2021 Been out of the 2 stroke racing business for more than a few years... but over the years I ran Klotz as well as others in my Suzuki RM 100’s... I didn’t notice much performance differences... Have her lean over that tank when she gets on it... that thing will scream... it is probably faster than the 100’s I raced back in the late 70’s early 80’s... 1 1 Share this post Link to post Share on other sites

She and her sister are on a PEDAL bike ride currently, so until then just some still shots! 4 Share this post Link to post Share on other sites
chucksterock 15 #5 Posted March 21, 2021 Any quality two stroke oil should be fine. Yamalube has an excellent reputation. I actually haven't run Yamalube or Kawalube. I race karts and have a run mostly castor based oils in a lot of my engines. Am currently running a CR250 motor on the kart and went with Klotz Super-Techniplate which is a synthetic-castor blend. For just playtime, I'd recommend a synthetic as castor oils need to be used immediately after opening as it has an affinity for water and will come out of solution. 3 Share this post Link to post Share on other sites
SylvanLakeWH 25,494 #6 Posted March 21, 2021 Nice! Might even be quicker off the line than the WHrat WHRecker... but don’t tell her that... 2 Share this post Link to post Share on other sites
Oldskool 6,640 #7 Posted March 21, 2021 I havent noticed any difference in any of it really. Is it oil injected? Anything we have that's oil injected we use dealer recommend oil, anything else we use what ever is available locally. Any seizure we have had was ussually do to injector failure.

tom2p 2,394 #10 Posted March 21, 2021 pullstart - congrats on the KX65 ! my neighbor had a KX65 - rode that little thing and it impressed - it was a rocket ! been out of the loop for too long - so can't help you with the oil I used Klotz in my Yamahas - Golden Spectro in my Suzukis - and more recently used Bel Ray and Maxima in my Kawasaki had good luck with all some of my friends used Yamalube and they had good luck also I typically mixed somewhere around 32:1 - 36:1 ... some of my friends were around 40:1 ... and one I recall was around 50:1 (ouch) 1 Share this post Link to post Share on other sites

The seller has a CR250R he thinks I should buy. The 65 is fast and dangerous enough for me, I’m thinking maybe a 125 is in the near future though! 2 Share this post Link to post Share on other sites

Most 125's seem to have a wicked power change as they come on to their power band. As for 2-stroke oil, well I'm an Amsoil man all the way. It is full synthetic, low smoke, super slippery, and also a gas stabilizer. I ran it in all my 2-stroke bikes and snowmobiles. Now I run it in my boat, chainsaw, weed eater, Mantis tiller, etc. 1 1 Share this post Link to post Share on other sites

The pull feels about the same from 0 throttle to wide open. The 125's that I have owned felt more like they had a turbo lag so to speak. A bit of a lag in power from the start & then BANG they took of, shift and the short lag is back until the R's come up again. This was my experience with my CR's at least. With 4-strokes this lag doesn't seem to be present in either the 125 or 250 at least with the XR's that I rode.. 1 1 Share this post Link to post Share on other sites
SylvanLakeWH 25,494 #16 Posted March 22, 2021 I’d get the 250... a lot more fun to ride around rather than “race”... @Achto hit it on the head... both will be very fast... Share this post Link to post Share on other sites

That's what the clutch is for, let it slip some after you shift to keep the rev's up and no lag, it's all hang on! Some of the new dual sports look pretty capable, not so "full on MX" and have an advantage of being street legal 1 1 Share this post Link to post Share on other sites

The guy is offering to let me borrow the bike for a day to see how I like it! We’re 45 minutes away from each other and I don’t even know his name! I posted my non-running Raptor for sale yesterday and already have two people lined up to see it. If it sells, it would nearly be a wash! 2 Share this post Link to post Share on other sites

Very controllable power and plenty of it. Though you may need a step ladder to get on it. If you really want to grab life by the "short hairs", keep your eye out for a CR500. Twice the power of the 250 and weights less than 30lbs more. A hand full of throttle in 5th gear can lay you on your back. 1 1 Share this post Link to post Share on other sites

A hand full of throttle in 5th gear can lay you on your back. My cousin had a CR500 back in something like 2005/06 and stashed it at my (mom’s) place before we went up north to the dunes. I took it for a leisurely stroll on our 25 mph street and saw the light that day when the front end came up in 3rd or 4th gear! No, I don’t need a 500 2 stroke. Nope. As for the step ladder? He said he can barely get on it without standing on something and I’m no taller... just about 1/2 the weight. I might have to take the lowering kit off the HD and stick it on the Honda! 3 Share this post Link to post Share on other sites

Mom or Dad holding the rear fender to balance them waiting for the gate to drop... not sure the lawyers would allow that these days...

Why so high? To soak up bumps? I took the 65 across the field last night. 5th gear, wide open. 60+(?) mph guessing? Just as I realized I had no eye protection, I came about a washout wall that was a good 14” high. I burped the throttle on that little thing and sailed right over it! Somehow dirt flew up and got me in the face, but no other harm done. Their ability to soak up the whoops is incredible! 1 Share this post Link to post Share on other sites
Achto 27,509 #25 Posted March 23, 2021 (edited) Yup, to soak up bumps. I started out on older bikes with dual rear shocks. Beat the crap out you. Thought I had gone to heaven when I got my first bike with a mono shock on the rear. Edited March 23, 2021 by Achto 2 Share this post Link to post Share on other sites
