Last week checked the compression, its 150 in both the cylinders. Still in Run-In. Pulls clean, surprisingly refined for a 2 stroke motor,Timing is tad on safer side, and needle position in 2nd from the bottom. Will post some pictures of spark plug after weekend ride.
So far so Good!
Cheers!

150 is considerably higher than normal. So it is better to run safer timing.
Your run in over.

Tanvir and I took her out for a spin this morning, did a 60ish km run I have to say one thing about the motor damn thing pulls like a tank. I only revved her upto 7000rpm in the lower gears and it totally blew my mind. I am pretty sure with a bit more tune up and timing it'll be an absolute joy to rip. The cdi and the way it is ported they all just gel in so well damn you have to ride it to believe it.

Thanks for the feed back dafc.
Im sure Tanvir will figure our how lucky he was to get such a build sooner or latter.
Im also pretty sure that the run in is over.

Yes when we do the porting we match up everything the ports are designed to work with the CDI Map.
You have to ride it to understand this.

Don't have the camera like Go-Pro.
Need to fix the fuel leak from Left side engine case, had re-sealed the Neutral Switch but again the oil is dripping.

Lifted the needle to the middle position, it ran considerably hot, again switched to second from bottom, it ran cooler.
Bangalore and Patiala has altitude difference, Bangalore-932m, Patiala-254m. taking this into consideration and humidity on an average-60%, should I upjet?
@Ron What are the mains jet size? I think its either 210 or 220. Pilot stock! Right?

Stock pilots.
Run on richest clip. Bangalore is 3000 Ft. Diff is like CBE / Bangalore huge.
If you want larger jets. Send in the old ones.
If its running fine dont play with it.

Neutral switch covers are in stock let me know if you want one.

Run-In over, have clocked 470 km during run-in. Now have shifted bigger main jets, 220 mains(RDD size) and stock pilots. Wiring sorted and routed, all the electrical functions(Lights, Horn, Pilot lamp, turn indicators) are functioning now.

Sifted to M800+Yamalube.Now have to look into suspension at high speed(front-end) and braking. Power band is addictive and body shaker.
