srx still overrevin'

[the tree man]

2000 SRX 700.Primary has WWW and stock weights with 4.5's in both holes.Secondary has green spring wrapped at 80 degrees and stock helix and a new belt.First time out this year yesterday and it's still spinning 9000 rpm on the fireguard.On hard pack when you pin it it jumps to about 8600 and climbs to 9000.Will extra gram in the outer hole pull me down enough or is there another reason this is turning so fast.Lot's of you guys run this setup just fine.What the hey is gong on?

whats the gearing ?

 

[bluemonster1]

the snow is to loose yet to test properly.You are over reving right off the hop.Try a stock primary spring and see what happens.What are u engaging at...4000 rpm or higher.

 

[the tree man]

Can't say for sure but the machine was completely stock when I bought it.

 

[the tree man]

It engages well below 4000 but I was hoping the lighter spring might load the motor a little quicker to keep me in the powerband out of the hole.Seems to have helped a bit but the overrev is pretty bad.I guess to check gearing requires pulling the chaincase cover?

 

[harness racer]

gearing , drive sprockets and secondary tension/ spring rate will all contibute to over /under reving , you really need to know what you got , , example if the gearing ratio is closer to 2-1 the higher it will rev and the " recipe ' w'ont work "


what helix is in there ?

NEED A DEFFERENT HELIX BUD. 3:16 (yammie tony)

like the GOD said...what is the helix in there now anyways...a 51/43

 

[the tree man]

Helix is stock.Is the RX1 helix a decent option?May be able to get one for cheap from a buddy with the 4 strokes?

Go back to the stock red secondary spring at 80 wrap & I bet rpm,s will be dead nutz on.

 

[harness racer]

if the helix is stock ? not cut than it should not rev 9000 rpm

 

[YAMMIEGOD3:16]

That Rx1 Helix Will Work With Your Green Spring. 3:16 (yammie tony)
