Hi Guys,
Looking to get a little more out of my 98 SRX600. I have these options, but need some guidance.
I can get some heads already cut by .030 and do the base gasket mod. I am also thinking about using a race logic porting template to do a little porting while everything is apart
Here are some ??'s that I have:
1) Will it be a good combo to do the cut heads and porting?
2) Will this be OK on "pump" gas usually I run 93 octane now.
3) Any idea of how much of a HP gain I will get?
4) Do I need to change the jetting, and any idea of a base where to start?
5) Any ideas on what I will need to change my clutching to? I have the Hauck Magnum power shift secondary, not sure if it is a stock helix or not. Red spring on secondary. I will weigh in at a little over 200lbs fully geared. 70% Trail riding 30% racing with my buddies. That is all the clutch info I have until I rip her apart...
Thank you in advance for the use of your knowledge, and your help!!
Oh and BTW

Get the engine ported. I ported my 99 600 SRX & it really woke that puppy up. Stock jetting & 93 octane is fine with porting. Clutching should be 83-8500 rpm at wide open throttle. It has been a long time since I had my 99 600 sRX but for clutching I ran 8bu-00 weights with 1st hole empty & 2.4 rivet in tip, 45/39 helix silver secondary at 60 degree wrap. You can also leave everything stock & cut heads 10 thou. I did this on my 98 600 SRX & it worked well too!
THANK YOU TURK !!! Yes I am Yelling hee-hee.
1 More ? OK with stock jets if I cut the heads or do the gasket mod?
So where do I send the beer??

That sled is jetted a little liberal. There is lots of room for stock jetting with mods.
