I am in the process of going to 95" on my 01 standard(bagger)
carbed flat tops andrews 36g cams gear drive and adjustable push rods.
Compression will be approx 9.5-9.7.
My Question is:Should I change oil pump spring or is it OK left stock?
Been reading forum and want to do it right first time...
Any other advice will be appreciated.
Forgot to add heads are being cleaned up,(mild porting)
decked slightly to achieve compression wanted and using0.030
cometic gasket for proper squish.....(?)
Thanks for all the great info,
have had many shovels but TC is all new to Me

HMMM I think you are meaning to say 37 cam?? That cam runs very well in the 9.5.-9.8 range for compression. We use and sell the LMR spring for the cam plate. It is a great product that will increase the oil pressure, when hot they tend be rather low on oil psi. Also one other thing that we don on all plates is check the bypass for pop off psi and make sure that the plugs in the cam plate are not leaking, lap the bypass plunger to ensure that the pressure is steady and not leaking.

By the way what model are you installing this into?? As the 37 works better in lighter bikes and the 26 runs very nicely in the baggers with mild port work.

 

Correct 37's my mistake.....
Ralph at andrews tech sold Me 37Gs.
Not good?

 

I went with the 26g because of having a heavier bagger. I also used the LMR-002 spring that I bought from Steve (HDWrench) above. Should be getting my heads back this week and buttoning it up.

 

I already own 37G's ........
Any advice? Will I have detonation problems on premium fuel?
Advance or retard timing?
Will buy spring.Sounds like good insurance.



Thanx KZ
