Hi all,

I bought a 1995 916 with SP cams (i don't know which kind yet) set to work in the upper range (bike has a custom eprom and has 12000 rpm limit).

It pulls well over 7000 rpm, but unfortunatelly i don;t use the bike for race only (as it has been used before), but 70% of the time for street.

What i want to do is set the cams to the normal 916 range and then order a FIM eprom to suit this.

Can anybody tell me what is the normal setting for the std, A/A, G/A, 996 SPS cams so i can dial them to the factory setting.

also, can anybody help me understand what is the best setting i could do to benefit most of the cams?

Thanks and regards

Oh, welcome to the board by the way, and thank you for asking, I'll have an ice-cold Guinness while you're at the v-bar

The SP cams are a "racy" grind. It's not a case of dialling them to a softer setting, but swapping them for probably BP cams will be the only real way you'll get the low/mid range back for road riding.

Thanks Phil

Nelly,

But the standard 916 SP was still a road bike... how was the driveability in the lower/mid range?

It was great... if you pay for the work to be done, i'll have the SP cams and EPROM

you can have the stock items from my 98' 916

By the mere fact your asking this i would suggest it is a tad confusing!

i would suggest you go to a trained professional and tell them what you want!

indeed andy i'm a bit confused because there are a lot of things i don't know about my current engine setup.

I started a discussion with Brad from Moto one about this and i hope i'll get some clarifications. The first thing i need to do is to find out what cams i have. This can be done by measuring them or by checking the marks (numbers/letter) stamped on.

does anybody have an idea what are the possible codes written on them?

I checked a set of standard ones and it has OA/OS and VA/VS on them (which means Orizontal Admission/Exhaust Vertical Adm/Exh of course) and A1

I guess A1 is the sort of code Brad was talking about...

Does anybody have an idea?

Thanks

Cipi,

I have just taken a set of standard Strada cams (A1 grind) out of a low mileage 996 motor if you need 'em.

Rgds, Rob

Thanks Rob, but i have another 748 engine that has the vertical cylinder head cracked and i keep it as spare parts.

Regards,
Cipi
