Hey guys, looking at building a new motor for the 740 and looking at bigger valves and cam along with porting in the 531 head i have. Any idea where/who i could source these valves from? cheers
Philia_Bear
Rsi is currently about the best option
Exhaust 38mm
Leave intake as stock
Polish everything and deshroud the valves
Barwick10
sweet, thanks. would you recommend new intake valves at the same time? stock springs do the job?
Vee_Que
Stock intake valves are huge vs exhaust valves. Have them checked but if ok just leave them. Boost will make up the flow difference too. I assume you plan to use a bigger cam as well?
Barwick10
OK sounds good. yeah i was thinking IPD cam just because they are relatively cheap and will be boosted for sure

I have a rebuilt unit from a 95 940 with VX3 cam for $550, fully rebuilt
Barwick10
That's actually very tempting. What's been done to it?
iceton1975
FULL rebuild what ever was needed to be done to make it a near new head
Barwick10
Yeah nice. Got any photos? I'm very inerested. Are you free before 6 for me to give you a call?
Ex850R
Just call him , it is a work phone and the head is a work one....
Barwick10
Whats the number sorry? Haha
Vee_Que
It won't have bigger valves though.
Barwick10
Mmmmm possibly not but it's still not too bad for that price. I was looking at rsi and its bloody 80 dollars a valve!
Philia_Bear
its $80 for a set of 4
Barwick10
Oh well that's much more reasonable. I read it as 80 a valve haha
