klr650 exhaust cam

hi guys i'm new to this forum
just bought a 1988 klr600 it's just had a rebore, new piston and rings the kacr fell to bits in the head hence the rebore, the last owner put another cam in it but cut the kacr off the end now its near impossible to kick start and the elec starter hasn't got the power to turn over.
what I was wondering is will a cam from a klr650 work the same as a klr600
or should the starter be able to turn over and need replacing
thanks for any help

did a little searching looks like the 600 and the 650 both use 29mm shims. also if the starter isnt turning over there is something obviously wrong. either not enough juice or possibly starter is going bad. it is an old bike might look into replacing it but try chasing all other options first.

What country are you in? I ask because KLR600's were Only Sold 1984-1986, in the USA. 1987 was the beginning of KLR650's in the USA.
Anyway, according to Kawasaki parts screen, The Exhaust Camshaft #12044-1197, was used for 1984 600's thru 1995 650's.

You can go to www.kawasaki.com, go to owner info in lower LH corner, go to parts diagrams, click on reference #, click on (?) for part info/fitment.
I could be wrong, but I would think 1996-2007 would also work, Somebody correct me if I'm in Error on this.

Hi I'm in the uk I've since taken the spark plug out and it turns over fine, the timing is fine ,I'm getting a spark , I've ordered a used exhaust cam for a 650 with kacr on so hopefully it should be easier to kick start ,I've ordered a starter repair kit so that should sort that out, next thing to check is carb setting as it's had new jets but not been set up
It's old but been 90% restored just needs finishing
I'll add some pics when it's done
I'll keep you posted on how this turns out
Thanks karl

Hi guys right finally got the bike to turn over
And fire it will only run on full choke and only revs to 4000rpm then dies and back fires, if you turn off choke and won't rev at all
I think it's a problem with the carb the last owner said he changed the jets but I've since had it apart and it looks very worn so what he changed I don't know
I've ordered a second hand carb so will see if that makes any difference.
If that don't work ,time to bring out the midnight oil

Sounds like diaphragm air leak; my suggestion: Check diaphragm fabric for tear or hole; MAKE SURE DIAPHRAGM LIP IS PROPERLY SEATED IN ITS GROOVE IN CARBURETOR CASTING.

Without an air-tight diaphragm seal, the carburetor can't function properly; slide won't rise with venturi vacuum as it should, needle won't uncover needle jet and main jet as designed. Result: fuel-lean mixture; "choke" (starting enricher) activation required to provide air/fuel mixture fuel-rich enough to support combustion.
