You dont have to rejet, i didnt, and i have the same motor

 

The moose module will only help your lower acceleration. If you want more acceleration and speed, you have to go with the Dyna.

If you really want more power and speed, sooner or later you are going to have to re-jet. If you don't want to learn how to work on it yourself, or have the money to pay someone else, I would leave it stock. Once you start down the road to more power, you won't want to stop with just a timing mod.

 

Did you ask Mike if he's sponsered by Moose or Dyna? I know he has a great deal of knowledge but you also know he has sponsers.

 

My Dyna comes tomorrow for the 650SRA. I cant wait, Ill let you know my opinion.

 

Num482,
Did you get your dyna. What do you think............................................. ................

 

OK, Ive had my Dyna for a few days. Its been snowing like crazy so I've only been plowing with it. First, the install was super easy, it was harder getting the seat back on. Second, the machine fires up a lot easier in the cold, before it took say 3-4 seconds with choke on and no gas for it to fire. Now it takes seriously 1 sec or less and idles a lot smoother. Its been cold here to, single digits, negative digits with windchill. I did notice a slit hesitation when going a steady 6-8 mph but once the machine fully warms up its completely gone, but it also did that with the stock CDI. Throttle response is a lot better, fan seems to come on less, after the machine is warm it runs a lot smoother whether i'm just putting along, hitting the gas, or just sitting idling. SO far I give it 2 thumbs up. I really cant say much about the performance yet, again since I haven't had it on dry land/road but it does seem light up all 4 easier. I am very pleased, well worth the money.

 

Num482,
Good to hear...........................
