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

Yeah

Yes😊

2024, Yes.

I be living in the future

Yeah

this is a built bike. watch some of my other videos about it, the speedo does indeed say 65mph

your 150r doesn’t do 70 stock.

@@american0153 he is right a stock Yamaha does about 50-55, and a 150R Stock does not do 70.

i might make a new video soon

Not sure. fixture was re-lamped around the 19,000 hour mark (3.5 years)

the etching on the bulb is all worn off

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.

@@american0153 thank you I really appreciate it

@@fake50cc the suffix (genuine wiseco part number) on this piston is 2m355, while a second gen piston is 771m.

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

yes, it is a great bike. I’ll upload a video later in the future going into detail about it

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.
