pic of her all together.

my compression tester don't work right, reads @110 psi but I can't trust it. Back half of fan shroud was a big help... topping out between 290-340deg.
Doing a slow break in...not exceeding 30mph for another 100 miles or so, then I'll see what she can do.

Another update...Installed 3 headgaskets but CHT was climbing to 376 deg within 1/2 mile. never had the left half of fan shroud so I orderd one and installed it. removed oil injector and filled tank with 32:1 honda injector oil. Now after 1 or 2 miles she only gets to 306 deg. Very happy with that. ...

stock head and airbox...airbox has been opened up. the stock head is way to small. your compression ratio will be above 12to1 for sure. add head gaskets to bring that ratio down so you can run that kit on pump gas. what did you open on the air box? doing that will lean out the whole jetting system....

#68 stock SA50P and #78 stock SA50

I'm running a stock #68 drilled out to @ #95

main jet is drilled out to #95 also running 2oz premix with oil pump tied WO

Thats the plan anyway. Can't afford another melt down!!!

have you dont a compression test on it??? i no its a dum qustion becase its new but if its 200 it to hight and will run hot ...and make sure you state i did it with the starter or kick it it make a diffrents... swimmingfree The compression tester I don't trust...95 psi. I use and electric start. go...

stock head and airbox...airbox has been opened up.

ran it tonight to work and back. 5mi each way. very windy out and she spiked at 405 deg riding into the wind. on the way home (44deg out. cold ride) she spiked at 435 deg...got me a little worried. other than that she ran great.

had half a tank of 32:1 premix left so I topped it off with plain gas. Tied oilpump WO. Manual states do not exceed 80% top speed for 600 miles and donot keep a steady speed. If it gets close to 400 deg I'll shut it down, don't want another melt down in the middle of nowhere and freezing temps...lol...

Update on the progress so far. Installed a new 65cc BBK, Trail Tek CHT gauge, reinstalled #88 jet and a Blue LED light bar under front wheel well for added visibility. Seems to be running well. Front wheel stays on the ground but I'm taking it slow till it breaks in...also I reinstalled the oil pump...

Going to try those. I just hope it keeps the front down. Going to reinstall #88 jet and hope I don't burn another pistion

Looking at a set of 16X42 gears 9.19:1 ratio
will this keep the front tire on the ground?

as far as my tester read it ws 75-80psi when I first installed the kit...I know the tester is wrong. And as to the break in...Yes, it will be a slow break in!!!
