SXR compression increase

[Don 79 TA]

Since she uses 1/2 the fuel my ski does, and to avoid confusion of different fuel jugs and all, i want to put the 24cc domes on her SXR to use 110 octane gas.
price of fuel is not a problem and she is looking for alittle more snap when opening the trottle

we have the ADA head and RD timing advance with the RAD flywheel
any problems doing this using the non-girdled head?
i don't think we will run into overheating issues, and she doesn't run WOT

I think it will be ok, just wondering if anyone has had issues with the SCR with increased compression

i'll use the Klotz R50 oil too

installed the domes today
fired it up, was a little shocked that it sounds like stock

maybe just me, i just thought maybe it would sound meaner and shake more
but when you blip the throttle you can feel the quicker rev

we are heading out tomorrow so i'll see how much better it is

BTW.. makes handling the fuel jugs in the garage easier, no more guessing which is which..

next idea for this setup is possibly the SXR big bore setup, although i don't see ADA offering domes for that setup... and possibly GroupK's big bore sleeper setup

Pay attention to the noises your SXR crank makes. If there is an inherent problem with them the crank is it.

haven't heard anything unusual
it's an 03
in a few months looking to rip it apart for some mods to it (just lacks bottom end snap)
of course i am used to the Lamey setup in my ski, but even she says it too

i was just a little concerned about it over heating, but ADA and some others said not an issue, espcially since it's not WOT all the time either
we'll see

flywheel next!

we already have the RAD aluminum flywheel on it

i've done alot to the ski already

well took it out today
you can definately feel that bottom end wind up now
she likes it, but i think once we get her motor work done, she'll be back on regular gas.

it made the bottom end snappier, not like a tremendous difference, but it easily pulls my fat a$$ out with no prob now

and she can launch easier when hitting boat wakes
