Noone makes a cdi up to this point. I dont believe you would actually gain any top speed(the machine is limited on top speed by the clutching(gear ratio)) because you never hit a rev limiter when you are topped out as fast as you can go.
Kurdtus - how did you know the Rhino CDI would work?
I see that you have an EPI clutch kit too... what made you decide to change the clutch, how did you find a kit that actually fit the wolverine and what, if any, change did you notice by adding the the kit?
I tried it because it seemed like they were a similar enigine. Took the leap and it tied in nicely. I think a grizzly cdi would work but being a bigger engine i figured the curves on that would hurt something.
As for the Clutch kit. It adds heavier weights and makes the engine engage at a higher RPM giving it more bottom end. Youd notice if you put it in. But if you get it cut, it engages even higher.
We were in the mountains riding this past weekend and decided to jump out on the pavement to save a little time. My Wolverine 450 jumped up to 50 mph (going uphill) and them promptly fell on it's face and started missing like crazy. From them on I could only hold about 2/3rds throttle at 42 mph. If I mashed the flipper any further the missing and maybe an occassional backfire would come right back.
From a standstill I can mash the throttle for about 7-10 seconds before the missing starts. So for mountain roads it's just fine but, when things open up is when the problem shows up.
WTF?
Then my buddy on his Polaris 500 Sportsman blew his belt and I end up towing him back over the mountains for dozens of miles.
check your clutch make sure you dont have some grease where its not suspossed to be. I had that problem myself and once time it was water in there causing the belt to slip and another time it was that i had slung some grease out and it caused the problem.
