Can a srx engine be adapted to fit into a sx700r pretty easily. Is it the same case size and or mounting with different cylinders and carbs etc...
can it be done, yes, is it easy...no! getting the mounts to fit wont be too bad youll have to do a little fab as they use a differnt front bulkhead. The pipes and such will not fit the chassis unless you cut and weld on them, sx is narrower then the srx is..
ADD: the cooling system is way smaller on the sxr as well!

800 (bill from lake villa IL) has a (factory 800 as he claims) SRX motor in a SX chassis. send him an email
He used aftermarket pipes... cant remember which ones

IMO:
A "Red Head" 700 SX that is properly ported, piped, geared, clutched, ect can be a rocket and still reliable. We have 2 trail mod SXs that have numerous miles/seasons on them and they don't take a back seat to very many sleds including my SRX. I don't think the work required to convert an SRX engine into a SX or SXR chassis is worth the effort. The Red Head engines are also quite a bit lighter with no power valves to clean or maintain!

srx engine in a SX700R
Based off this info I have 3000 miles on my engine and it has a hole ( the size of a dime between 2 ribs) in the lower crank case. Should I try to repair the hole and just rebuild the top end or just pull it all apart and do a top and bottom rebuild. I am thinking the later since I will have to take off the lower case anyway. Looking for some advise as which way to go and where best place to pick up parts.

I have tried to repair a case before and it is a pain in the butt. I was TIG welding it and every time I finished a weld, as it cooled it would start a new crack, meaning that the heat from the weld was causing stress to the casting. I guess you could probably preheat it, but I found another way to do it was to put a needle gun to the weld right after you weld to help release the stress. Anyways, I decided on my own to just find new cases to ensure I didn't have a leaky case. So long story short, probably less headache to just find another case.
Where are you in S.E MI rocket?? I am in warren and can confidently repair your cases.
Whether you decide to repair the case or replace it I would suggest you check everything over very carefully . To break the case you obviously had metal between the case and crankcase which means the crank/rod bearings ect probably have taken a beating and need to be inspected and cleaned.
