i run the oil rich. had 2 previous pistons seize up due to excessive heat on the exhaust port side of the cylinder wall running it at 42:1. i run it 30:1, and haven’t had any issues
@@american0153 but that sound still dry to me ,or maybe your muffler sound like dry, i just have little knowledge of porting,but yeah sound like that is dry in my country.in indonesia 100cc 2stroke is rare just have 115-150 cc here
3:20 gives me final season of your favorite cartoon vibes where the characters break the 4th wall to tell us the viewers goodbye or go their separate ways if it’s a friend group😩😩
run a first generation DT/MX100 (1974 / 1976) forged wiseco piston. The LT1/2 and the LTMX100 both use the same type of piston. i run that same piston in my 1999 RT100, since it has a bigger and a more symmetrical piston window, which helps to better the flow of the intake charge. (so basically it’s just one big window with a rounded roof). you’ll gain maybe 1-2 horsepower with that, as opposed to the stock “twin hole” windowed piston. the bridge in between the window on that piston does a really good job of obstructing flow. i’ll make a video about it and send you a link to the piston kit on ebay.
I got a 03 yz250f kibble white valves ported head and it currently needs a crank shaft I would recommend overturning it😂 all I did was catwalk mine tho that might of had something to do with it
no need to worry about cat walking one of these, since the 01 - 11 yz250fs use a dry sump, there is no oil in the sump. it is pumped directly into a remote oil reserve tank, where it is then pumped (sprayed) into the engine by means of oil jets, passages, etc. your crank most likely failed due to lack of proper oil changes (from previous owner) or a defective crank from factory. it could’ve also had an excessive amount of operating hours on it.
@@american0153 I appreciate that I was wondering if i could rebuild it and set it up for catwalking i had it for a week and when it came apart it destroyed the valves and the head bent sideways some how it’s crazy I would have to send you a picture
It did not. thermoelectric coolers are EXTREMELY inefficient. the one used in this video was a 60 watt element, which only produces about 15 watts of cooling power, or about 5 btu an hour. barley enough cooling power to drop the temp 1 degree. you can see that i attempted to use a “swamp cooler” to cool down the hot side, as that increases cooling efficiency. that also didn’t work. it takes failures to learn, lol. i have a new setup with these little coolers. i’ll make a video on that later. interesting buggers they are.
