Srx

Paul,
Can you bring the front suspension boots we spoke of with you??
I would love to get them put on next week with my redone hood...

just had a brain freeze i think we talked about 8 years ago when i built mine .do you have a custom hood on that machine.i believe you sent me pics way back when interested to see if it's the same machine.norman ball 111 used to race one for psi perf back in the day he is on the back of the catalog.neat stuff...!
 
81 srx

still have it . had someone that wanted it but have not seen any cash. thinking of just keeping and running it.
 
do you have any pics of it though? and where did you get the sleeves to bump her up to 500 cc's, I would love to do that to my race sled, as im racing it now in 600 mod class and can use more then 440cc's if i can get it.
 
it runs 78 srx or ssr pistons... 81 440 was a smaller bore with longer stroke than the 76 to 80 srx. custom made sleeves from L A sleeve co.
 
80 srx bore 68.5 stroke 59.6
81 srx bore 66 stroke 64

if you build a 81 engine you need to use the 540 vmax crank as the 81 will not live long.
 
540 Hp

My Delaughter 540 mod makes 125hp I dont know how much a stocker makes maybe 100 hp.
