not to sound like a punk but that is wrong....you will have issues when things are hot unless you have thermal coatings throughout the topend which you probably don't...Ive had 2 with the same piston and both of them knocked on pump gas 91 octane fuel from california out in the sand when the ambiant temp got above 87degrees or so...it will knock even more so if you're piston is in the hole as this elliminates the quench area in the chamber causing premature detination....now if you only ride the hardpack you might get away with it because the sand works them a whole lot more and heats them up fast,or if you can get higher octane from another state as california fuel is known to loose its octane within a month and is crap fuel from birth, you need to retard the timing down trust me unless you drive like an old lady then you'll be fine...........you cant tell a damn difference while driving it with the timing lower,or on a dyno,but out in the dunes the lack of timing equals lack of detonation............most cdi's advance the timing upto 42-44 degress total advance which is f'n nuts, I mean f'n nuts....no wonder everybody has head gasket issues on these damn things along with the factory stretching head bolts........yikes.........found out the hard way on those..Yeah Camshaw, I was worried about the pump gas issue with the high compression piston but Steve at Benchmark Performance told me I would have no issues.

Great info. Do you happen to know how much advance the Hunterworks Tri-Fire CDI has?(the stock replacement dynatek $150 cdi topped out at 43-44degrees.................yikes...)
Steve, I will re-tune the MSD on the dyno for you if you would like to see the gains from the cam change. Hit me up when you are ready.I have the stage 1 raptor cam right now and it runs good. Now that I am using the MSD FI with 3D mapping I want to try the stage 2.
MSD 4217 CDI, it is the only ignition we use on a Rhino 660/686. Having the ability to remove timing in the higher RPM's is key to keeping a motor reliable in a Rhino.How do you retard the timing?

what!...........but then they recommended a 11-1 piston and hot rod camshaft!!!.......??I also had a ported head for the rhino but sold it based on Benchmarks recommendation. They said the ported head will make my lower end unreliable.
