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...
srx engine in a sx700r
- Thread starter snowrocket
- Start date
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.
