Motor 4 Stroking like a son of a Gun!!!

p.s.

just curious...why rack mount when that frame looks like it would accept an engine quite nicely?

having all that weight up high and far back is just so awkward... especially when you open a gate or move the bike around the back or something...

not too mention the exhaust noise being reflected from the ground straight to your ears...
No need for pedal extensions, no burnt legs are two great reasons, full use of legs (can't sprint with legs splayed).High and far back, like where a massive human sits?Rack mounts are very stable, not awkward in the least, the only stability problem is sitting still on a kickstand (tip easy).The sound is behind you when riding.A rack mount can be connected/disconnected in minutes.Nothing to come apart BETWEEN YOUR LEGS.I'm bias, frame mounts look like c.r.a.p. wannabe motorcycles IMHO.My 2 cents,... of course will buy nothing.
 
Thanks Grinn, appreciate the kind words, only issues I think I have is that you can't really ride out the saddle, the motor acts as a counter weight and throws the bike all over the place. The Rack with motor is about 12KG in total so it is a fair weight and I am only 1.72m tall and weight 60KG.
The other problem is my mount is not far back enough so I could not really sit back on the saddle for obvious reasons.

I am going to try the frame mount option out, see how that feels, main concern there is the heat between my legs, rack mounted the heat is blowing away from me, frame mount the heat is rising between my legs (GASP!).

Also to update on my over fueling, I think I found the culprit, the little "prongs" that hold the float needle were also skew and stopping the needle from closing off the fuel completely, tested with so old fuel I had. just a little bend and seems better, going to try finish assembling the bike this evening and maybe get a chance to give it a run.

All I gotta say is that there's a reason Harley Davidson doesn't put their engines on the back of their bikes.
 
Thanks all for the great advise, six little strands of old headphone wire later and she seems to be running well. Just a little bit of "4 stroking at low throttle (just about 1/3) but from what I read this is desirable for when you going down hill, extend the life of the motor. When passing 1/3 throttle she evens out nicely and ziiinnnngggsssss away. So much more pleasant to ride now.
Balance is also way better now with motor in the frame.
 
what is meant by 4 stroking, your two stroke suddenly developed a valvetrain, just curious. i think for a rich condition you might want to go through the carb and adjust and jet if need be but as previously stated do it on the wot since this is presumably how the motor will be ran, i had a couple of these carbs that were way off and imo not even worth messing with so i bought the performance carb and everything was fine for awhile which seems to be the name of the game with these two strokes they last for awhile. 1500mi is my personal best.
 
Greetings all, so update on my Little Happy Times Motor, made the Jet smaller by soldering and she purrs much better when the motor is under load. Weird thing now is once up to speed / coasting speed she still 4 strokes. IE when under load she runs 100%, no Load she 4 strokes.
