Wow thanks for all the replies and info guys. I feel stupid, i started out using the 2 stroke oil and after i ran out of those bottles i started using the regular oil i had in the garage because i thought i read that was fine to use. That isnt too rought on it is it because ive sure gave it a beating last couple tanks.

Ill read through this again tonight and see what i come up with, i just ran her plum dry and ran out all my gas in the garage so i have to start fresh which is good.

thanks all.

Oil

How much oil are you going to use? I use about 4oz per gallon.

I love spad it is a cheap way to do an expensive hobby.

You are accidentally doing spmething called a pinch test.
I use it a lot..

The "pinch test" works within seconds on a RC engine (no fuel bowl), but often takes a few minutes on a Bicycle engine. It is also only an indicator of idle mixture, and not mixture at WOT. The jet needle has little effect on mixture past 3/4 throttle, where mixture is primarily controlled by the main metering jet. You can fry an engine quick if the mix is too lean at the top end, even though it is slobbery rich at low/mid throttle settings.

In any case, using 5W-30 motor oil is great for mosquito control and proper two stroke oil will reduce smoke considerably.

OK, got the right oil, ran 4 oz to 1 gal.

VERY little smoke. awsome.

and just a little earlier, i adjusted the c-clip on the needle jet up one, so its on the second one down now, instead of 3rd.

The mid rang seems ALOT better now, doesnt bogg out near as much. Wide open top end seemed less but if i read correctly that doesnt really have any effect on that so i assume its just because i never got the engine really that warmed up, i just took it for a quick pass is all.


OH, i was sooo ****ed. THey had a digital screen speed trap setup on main street that takes pics if you go too fast. well THat was there the last two days, and i was like, Oh i GOT to take my bike over there and see what it tops out at, here is my chance to finally know. Ride the bike clear across town and they TOOK IT AWAY!!!!


I but the guy woulda "LOL'D" when he seen a pic of a mountain bike on it haha.

when it was running its peak today, judging by traffic, it seems it was anywhere between 30-40, im guessing on the low side of that. Its got expansion chamber, ngk plug, ported head.

I really wish i would have ordered a freewheel gear, because being its a 3 day weekend, would have been the perfect opportunity to build a jackshaft. but that will have to wait a little longer.
