I ran them for years on a built 1000 and 1100cc. Cat tachs are fast, so run it 84-8600. Anymore and your top end will drop off big time.I have an 01 T-Cat with black magic pipes. Can anybody tell me what the rpm's should be? Im running about 8900. I think they should 8400-8600. Anybody have any idea? Thanks in advance. Dan
YES...Jeff Simon owned CPR...I remember him as a young kid when Olaf gave him his start...Wish I could find my pictures of the V-Max4 motor he made into a 6 cylinder...SWEEEEET...I ran cpr's which are said to be the same,86 and build to 8800 on a cat tach worked for me.I geared down to 23/40 also,it is really testing for you;re sled to get the max out of it.
Auggie did you ever ride and compare the two tachs?I have a 2000 ZRT 800 with a 1004 installed. The engine is stock except for Black Magic pipes, 2001 T-Cat stock muffler, V Force Reeds, 2,58 deg key and a Tempa Flow. Over the years I have tried running the engine from 8400 to 9000 rpm. It now runs the best from 8740 to 8760 and every now and then will over rev to 8800.
understood I am chiseled on ice so we have very good conditions.There is a lot to be said how some test and tune .I like to go when there is no one there and have the strip to myself.I picked up some [email protected] mod pipes to go along with my overzealous port timing so I have work to do.There seems to be many opinions on these tach calibrations and I would just like to see a vdo vs stock in action.Feelnthunder that is a strong run with reverse.I am working on removing mine this year and cant wait to see the difference.I picked up a old panther with reverse just to drag the t/cat off the trailer, I am getting old.The analog and digital tachs are usually close but the digital tach gives you 100% accuracy. The digital tach will give you an accurate read out when you first punch it but without a playback function or a "hold highest rpm" function you'll never see the rpm flash when you first punch it. Many times a sled will actually flash 100-300rpms too high when you first punch it even when you have it "clutched perfect" and then it quickly settles back down. Find an open field and a digital tach you can watch/read and go tuning.
