701 Footrocket build

Are the stator and flywheel from the same motor? I have never seen 62t electronics but is it possible to put one flywheel on the other system?

Here is a closer picture.



Pictures iv seen have a tab with an arrow pointing to the groove. my tab seems to be broken off.

They came in the same engine but I don't know the history at all. Can anyone tell me what flywheel this is or how to identify the stator and flywheel?

Well that's deffinatly a 62t flywheel

I wonder if your still chasing the cause of the original failure. Obviously the intake side has been modified.

What do you mean modified on the intake side?

 

[ajmps1]

Reeds and velocity stacks, are they stock carbs?

 

[EvanKrefski]

Did you check your waterbox after those? I blew mine up in my old superjet when it backfired one time.

 

[uwswimmer]

I think they are stock carbs, and yes I looked over all my exhaust after that.

 

[uwswimmer]

Anyone have any advise about what to do with my timing? Because the arrow on the case side is broken off I don't have anything to match the mark on my stator to. Anyone know what could have broken those tabs around my stator?

 

[hamanirb]

have U tried to use another cdi , it could also be cdi related because i had a msd enhancer break down on me and the ski wouldnt stop backfiring

 

[uwswimmer]

I have not, I don't have a spare. I will see if my buddy can bring me an extra over to test.

 

[uwswimmer]

I forgot I can use my blasters CDI i believe to test that. I would like to test one change at a time though.

Any one have suggestions for jetting or carb setup?. I have a 701 with an ADA head, 35cc domes, b pipe, dual 44s and aftermarket reeds and stock electronics, for now.

I found this in another thread, I don't have porting or total loss but would this be a good place to start?

The carbs you are using are for 760cc im not sure what jetting it needs if u want to run it on a 701
I would recommend in buying duel 38's it would be much more suitable for your engine , and it will be much easier to tune it

 

[ajmps1]

Look up the specs that factory exhaust gives you for a 701 with dual 44m carbs. You can run those carbs

 

[x2mafia]

look at the wear pattern left on the stator plate if there is one from where the screws were holding it down on the last motor

 

[x2mafia]

I was looking at the picture of your stator mounted in the cases. For some reason on my skis I cant remember it ever being centered up with the slots

 

[ajmps1]

Looking at your picture you might have the timing a bit off. The arrow on the tab is in the center so id try to align the mark on the stator with an rough eyeball of the tab center

 

[yamanube]

Looks like your timing might be a bit retarded which probably isn't your issue. Pull the stator off and scratch a line in what's left of that boss. There is a casting line directly in line with the timing mark to use as reference.

Thanks guys, I have new carb parts on the way and I will put it back together and try again, if the slight adjustment docent work Ill swap CDIs and go from there.
