Anyone upgrade their piston yet?
I threw a 14:1 in my quad and was thinking of upgrading one in the Rhino.
I know what most will say,,,Big bore.. In reading I have seen the motors pick up 4 to 5 HP just on a piston change,,,,but that is in a quad.
Just wondering
This is something that interest my also. Can anybody enlighten us?
Well, I havent done it......YET, but it's on my list. Ive spent many hours ready on this and here's the conclusion Ive come to...
Big bore 686 is a nice increasein performance and power, but it comes with risk. While I havent heard of lots of issues, there are definatly those that have run into reliability issues. Ive talked to people who've had no issues and love it, and Ive talked to people who've had nothing but issues. Enough to make me scratch it off my list. Reliability is a MUST for me!
High comperssion piston.....Ive yet to run into anybody who's had an issuee with this as long as you stay at 10.75:1. That seems to be the magic number. There are 11:1 pistons out there, and some people swear by them, but Ive read anything over 10.75:1 and your walking the line!
As far as performance, the high compression piston doesnt really get you any more top end, but it does help with low and mid range power, which is waht these Rhino's really need!
Ive also read that an aftermarket cam is a great addition to the piston. There's mixed feelings between the Mudbuster and the Raptor Stage 2 cam, but Im thinking of running the Raptor stage 2.
I'll be swithing to the 10:75:1 piston as soon as I get a few more hours on the Rhino......
Well, those are my personal thoughts and findings.....if anybody out there has actually done any of this, we sure would love to hear about it!!
