OK, I gave in, I've just put the #5 cam in, and the #2 cam is now sitting on the bench. I haven't yet tuned it up, and its got some major fuelling problems above 4500RPM, but it pulls much harder now from when it comes on about 3500. Pretty much dead below 2500. The #2 cam didn't "come on" at all, it just pulled hard to about 4300, then started choking. Definitely a stump puller. Never bothered to rev it much above 5000 since it was pointless. This cam however shows definite potential - with correct fuelling. BTW my engine is a bored L16 with a ported A87 head, 10.5:1 CR and flattop SUs. So to get the revs I deserve I need to fix my SUs. Anybody in Auckland have any thinner needles I can try? --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/[email protected]/ ---------------------------------------------------------------------
