Thanks for the fun reading, been a bummer weekend, I needed this.
Whoa...whoa...whoa.........are you saying the 50 class is stacked with illegal bikes? I don't believe it.....Just wait until your son gets on the KTM 50s and in the 65 class. Of course big bores aren't the same as pushing your son off the starting line. LOL!

Original44, Thanks for bringng this subject up! I thought 125, was 125 also, and was looking to build a competitive 125 just for local racing. But, I can bump to a 144? Cheaper and easier to maintain? Does anybody have input on the reliability of bigger bore cylinders? Thx

My Athena kit is treating me well.
It's not a bolt on kit. Need to grind out cases for piston clearance. If you get someone that knows what they're doing the bike will be reliable. If not the piston will explode. Also don't build a 144 without doing a new oem bottom end. Otherwise your rod will explode. The older bottom end is only used to the 125 not the new 144. Seen many pictures of blown rods with people who just bolt on a 144 to a 20-30 hours stock bottom end. That's a bad idea!
But even then I don't expect to get more than 20 hours out of a rebuild. But considering its $400 to rebuild a 2 stroke I'm ok with that. I'm at 13.2 now. But I also change my oil every two rides or 3 hours on the meter. Whichever comes first. I use klotz. It smells like candy. Lol. I even lube all my guns with that s**t. New air filters just as often or more....
If you want reliability keep the stock bore!!! But if you want your child to be competitive, you better cheat!! Local track promoters know it's goin on, and they really don't care! They just want the money!! One a cheater, always a cheater!! And yes, 19cc is a huge difference Hershey!!! My kid had been cheated since he was on 50's!!! It'll never stop, unless people start protesting! Put he money down, and protest. Even if it costs a friendship! And kinda funny local promoters sell 125's with 144's in them . Obviously this is why they raised the cc limit! Locals promoters usually change rules to suit their kids/ridersFor a Yamaha the Athena kits work great, ask Georgie Porgie. If it's a KTM I think the cylinder for a 150 should work.
I thought the oil in a 2 stroke is just for the clutch and tranny? The oil in the mix is what lubes the cylinder, rod and crank. Am I right or wrong?My Athena kit is treating me well.

That is correct.I thought the oil in a 2 stroke is just for the clutch and tranny? The oil in the mix is what lubes the cylinder, rod and crank. Am I right or wrong?
Your right . Do t know what he was thinking!I thought the oil in a 2 stroke is just for the clutch and tranny? The oil in the mix is what lubes the cylinder, rod and crank. Am I right or wrong?
Now you tell me....Everyone cheats in the Ama in 50s to super mini. FYI for you new newbies.
