Camshaft questions.

Anyone know if a 1982 1100 Spectre's camshaft is the camshaft used in the 1982 KZ1000 standard or the LTD.

In the back of my mind, I have been considering putting J-model standard cams in my bike and having the carbs worked on to bump up the horsepower. I may be off with this one, but the way I se it is that the standard had about 10% more horsepower that I can get by making my LTD engine into a standard (yes, I already have Kerkers and K&Ns). If this is whacked, someone tell me. Or, if there is a better route, let me know on that too.

Rick:

The cams for the D and K models are identical (same part number). However, the J model uses different cams (different part number)...what this translates to in terms of 'drop-in' ability or performance enhancement, I don't know.

The "D" model is the Spectre?

Correct:)

Anecdotal info:
A local guy was running a 81 KZ1000 CSR with a 1075 Wiseco kit and APE cams, when he decided to put the bike back on the street he installed GPz1100 cams, when he decided to sell it, he installed J model (standard) cams.
According to him the cams are rated in increasing performance like this.
CSR/LTD 1000
J (standard)
GPz1100
APE (I don't remember which ones)

I thought that the GPZ and standard kz cams were the same? I'm just trying to get more horses with out a cylinder replacement.

81gpz1100/standard J cams-intake cam one stripe ex cam no stripe

the gpz and J/ltd/csr...ect have different sprockets gpz's will have 1100b,others will have z1000

82gpz1100= 3 stripes

83-84 gpz1100 cams are the hotest and I think they have no stripes,the 84 cam is around .375" lift

csr,spectre,ltd 1000/1100,kz1100,police all 2 stripes intake,csr has gear teeth on ex cam and are around .315" lift

I hope this helps
