if you try it with the kick starter it will be higher.. not sure if a nother head gasket will help or hurt if you lose take off then pull it out...

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

Main jet too small. 88 main comes in stock 50cc bikes need a 90-95 like taz said earlier.

I agree with red eft also could the higher temps be due to you reinstalling the oil pump? Honestly fooling with that pump on a bbk is just a headache

And whats wrong with tcw3 oil?

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

My bad. Up until my post you never say that you drilled a 95.

88 main comes stock on a 93 elite sr af05

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. so you got 2 things going on thats causing the high heat

Oened the second tab on the Air Box cover. Planning to add a second head gasket this weekend or as soon as it warms up a little outside. Also going to find or burrow a good compression tester cause my new one don't work for s***!
I'll keep everyone posted on the results. Thanks for all the input!

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. Thanks for all the input.

What was your compression after the 3 head gaskets?

The lack of fan shroud was probably your major problem to begin with

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.

pic of her all together.
