I'll be happy if it can do at least the same top speed but I really want this one to be able to accelerate even better than the mountain bike did, that one accelerated really nicely but I'm hoping this one will do even better....

Surprisingly that seat is comfortable but it's most likely going to end up switched out for a cloud 9 or similar, it's not too bad riding around the shop parking lot etc, but that can change once it's on the road and doing 40+ ... I got a few other seats in the stock room that I'll most likely swap out once it's running.

Well it's pretty but I hope you masked off the intake and exhaust ports...
I know that feeling when more pics need to be taken but the customer rushes off before it can be done... it's happened to me at least twice on custom paint jobs I've done on motorcycles before... I got all the pics of the parts off the bike but before I could get to my friend's shop to take pics of the bike assembled it was assembled and delivered... and this guy didn't even take a pic of it after he put it all together...
It's a bummer but it happens...

i always wipe the ports down with lacquer thinner before assembly i have been doing the engines this was for a long time. the customers are always surprised by the prismatic paint it looks so cool in the sun light

seen folks do this and end up with paint on piston & cylinder walls

I have a broken muffler, dead spark plug and old intake that I always throw on when painting these (I also use a bit of tape over bolt threads too) - the broken muffler makes a nice handle to turn it with while painting too

might even have posted a pic here of piston with a painted spot in the shape of a port

Took the engine cover off to investigate the cause of some serious vibration above 3300rpm in my briggs motor. Found out the flywheel, though secured well to crankshaft, has something like .015 or .020" total play up and down. Guess this engine was worn more than I thought when I bought it used. I only put 500mi on it!!!

Thinking what to do, I see those shortblocks on ebay for $120 that I could transfer all the parts over to...
