120+ today on the gun!!!!

[ROCKERDAN]

So you hit 120 on the gun with a 23 and an uncut primary? That is great. I have a 23 39 setup that I was considering putting in but was afraid I would lose top end. Sounds like that will not be an issue if I cut my primary.

with 23/38 at 1 to 1(no OD) its geared only for about 115.....I had a slight amount of filing i had done to primary,and also dalton helix helps in back..

with the machining i had done today and the secondary shimming and machining,i can now run belt to top of primary on the stand...before it would go to about 3/16ths or so...but stock helix and primary stays down nearly 1/4 inch or so.

I think NOW i should be geared for 128 range....so now if i get that huge tailwind,or find a downhill lake(LOL) or add NOS...i can at least feel good about not running out of clutch/gear.

I just ran a 23 38 on Ulmers chart and with stock clutches running 8700 rpm it comes out at 113 mph. Do you think that the chart is not accurate?

On this chart i use 11,000 rpms..which is where i run my setup...also you can use 1 for Overdrive to be safe side.....try this gearing chart,it comes up at 115.94mph with 1 for OD...

if you put in .90 for yammie Overdrive setup,at 11000 it comes up with 128.83...so in theory i should be about there.

Id like to see ulmers chart..can you send it to me..?

Dan have you tried the Dalton Red primary spring yet?

Here is a link http://www.ty4stroke.com/download.php?id=24663 I do not know if it will work. Someone else may know where to find it it is in my favorites now.

Dan have you tried the Dalton Red primary spring yet?

I just installed it today....Dale says it will lower the hi engagement of proline kit...which is great!....the rest is same as proline spring...also great.

I also installed dales new secondary RED spring too....I will be testing all this,but it should be close to myu original setup overall.

Dan we just regeared down,back to the 23 top w/38 bottom on the rtx,and i will give daltons 66 riveted weights a try as i borrowed them from a friend,with my g/w/g yammi primary with two 1mm shims,on the secondary stock but cut 51/43 with the yammi pink at 60 degrees,but i would like to try dales red secondary,or i will have to get a new silver,as my old one seems to be sacked out,this past weekend we ran stock yammi weights loaded with 7 grms in tip for a total of 84 grms with the set up i listed,but with 24 top gear,it would pull 10,500 right out the gate and run to 10,800 on the long end if on anything hard,if loose it stayed around 10,600 and pulled preety good,but did not feel as strong as last year when i had it geared 23 top with my supertip weights,any thoughts.

Dan, Have you tried Dales 54/44 helix? I hear it has good results.

I definitely would like to try a steeper helix like that....I think with the torque and RED sec spring it would work well....Might order one of those soon.

Let me know how it works out. The snow situation in Maine still sucks so I haven't had any testing time yet. I did put the red primary in and run around for about 5 miles on some marginal local trails. The engagement is much better. It comes in around 4,000 or so.

What is the difference in the red secondary spring versus the black one that came with the Proline?

I'm going to Quebec next week - so I should have a full report on proline with red primary next week.

the red secondary from dale is a tad bit longer then black proline secondary....so it has abit more side pressure which is always good with this setup....also,the tangs are properly pointed(unlike the proline black)...which makes your twist more yammie like.(IE:70 instead of 100)....PL black was 30 higher when the kits finally came thru...if you recall everyone had to wind them differently then original directions with kit...as the black spring was made with tangs in different positions..but all in all these two springs when wound properly are nearly the same.

Just wondering if anyone knows what the angles are on the proline helix??....I had it written down last season and cannot find it...i know it says -1 on it.

thanks guys

You also don't need to do the washer trick with Dale's (called him Dave in previous post but meant to say Dale) helix..... They are already compensated to help with a full shift. John black could explain that better than I just did. I tried to get Prolines out of Dale, but he did not budge.


Also, are you running on the ice with the front end being lowered like that. Have you tried going back to a little closer to stock. I'm not sure if that's helping you on the big end. If the hole sled was slammed then I would say yes, but to me it looks like you are putting to much track on the ground. Bluebyyou2000, pulled 123 with stock height on his RTX....

i spent 4 hrs yesterday testing my newly cut primary for full shift...and you DO NEED TO SHIM Dales helix IF you want to get the full shift in which i have my primary cut for...I removed springs,and installed entire setup WITHOUT shims behind helix,..and NOPE!....the secondary would not allow primary to pull it down totally...it was close sure,but not enough...and IMO if i rode it like that i would have blown a belt as primary would have been pulling down hard on secondary while it was at its END of travel...

as i said earlier..once i shimmed it,the secondary actually hit the frame ..so i KNOW for FACT that the shimming made it go further.and it is need with MY SETUP..others may not have machined primary as much as I do....Dale and I have spoken endless times and He knows exactly my setup.....you are correct in saying Dales helixs are much closer for OD then stockers..but in my setup not quite enough...

plus there are more small things I do in my secondary setup...lots of little things that can me done to make things more efficient....some things need to be kept to myself.hehe.

BTW,does anyone know what the APEX stock helix angles are?

i think it was 51/43
