roller secondaries

well the guy who owns a local motorsports shop, sells the hi-tech roller secondaries and 911 kits. i think i'm going to go with both of those items. i hope its not too hard to tune to the trails. what's the biggest thing to watch out for on these rollers tuning wise?

is your local motorsports shop owner's name Dan? looking at your address location it looks like your dealing w/ the same guy who helped me set up mine.the helix he started me with was a 54/50. works pretty good. the helix I'm waiting on is a 52/48. go w/ the later if you can .either is good but I'm going more for top end. Tell Dan Todd said Hi!! This sec. is easy to tune on the trail & remains pretty light.
 
his name isn't dan. he was telling me to use the 52/48, as he runs that helix in his sleds as well. his name is keith w/karbon's motorsports. which dealer were you talking about?
 
I was told that a single angle helix is the way to go. A multi angle helix is just a bandade to cover up your other clutching problems. The hi-tech roller has a encapsulated roller so that the roller doesn't back away from the helix.
 
I used a Hauck roller in my srx at some asphalt drags I found that the dual angle helix (48/38 dalton) would pull hard with straight shift even if I spun out but 1/2 way down the track it would stop pulling for a second and then start pulling again. Almost like it paused for a second. But that could be that my rollers are a bit worn.

P.S
I was using heel clickers and a bender white blue spring.

I don't know if this you helps any.

same dealer Owners name is Dan , Great people. that helix sounds good for a viper. this set-up is easy to adjust , light enough,& once it's dialed in expect great perf. gains . p.s - durable& trouble free- very important !!
 
its good to hear that this 52/48 helix would be a good choice for the viper. its also good to hear that this setup is easy to adjust and light enough.
 
52/48 helix in the mountains?

Is this helix best for trail riding/racing? What about when you start hitting the slopes and start pulling some long hills?
 
the guys name is dan. i thought it was keith. it is karbon motorsports though. i was talking to him yesterday about the hi-tech roller and I think i'm going to get it. one of my buddies said he is for sure going to get the roller and 911 response kit. we'll have to let you guys know how it works out for us on our piped vipers.
 
Try to see if you can talk to Duane from hi-tech so that you can get a starting point and what helix to run. I asked him about the multi angle and he said he made them and tried them and they don't work as well. If you have things set up right a single angle is all you need. My srx pulls hard and is at the right rpm for peek HP through the whole range of speed, even at top speed.
 
ok, but this dan @ karbon's keeps telling me that these 52/48 helixs are the way to go on a yamaha. He said the 52 deg angle goes 3/4 of the way down the ramp and then the last 1/4 is the 48 angle.
 
Dont try and run heelclickers with that secondary and those angles. What a disaster, I tried everything for over a year. Dont know for sure who I talked to, Duane seems to ring a bell. I was using a straight 50 cut. He told me to get this green EPI spring which was meant for a Tcat, this would fix everything....yeah right. On my 780 SRX from a dead stop it would turn 9200rpm, by 400 feet 8000rpm, and eventually top out at 80mph running a screaning 7500rpms.
Best move I made was to trade even over for a complete RX1 secondary. Threw a green spring in it and ...wow what a difference. In the end Im using a 50-36 and its perfect. The roller was on the sled when I bought it, I would have hated to spend good money on it.

What did you do with that roller kit? If you would have put a stiff spring in it you would have had a different story to tell. I was having the same problems as you, I talked to Duane and told him my problem and he sent me a a spring that he was telling rx1 guys to use. I haven't looked back since.

AAhhh....read my post above. The spring was for a T cat. Stiff enough to the point you could barely get the clutch back together. If I did need a stiffer spring how do you explain the 700 rpm overev off the line. Traction wasnt a problem either.
 
Was that a primary spring or secondary spring? He got me a secondary spring. I used the secondary spring to get me close to where I wanted to be then I played with the weights a little to fine tune. So what did you do with that E.R. kit did you sell it?

Yes secondary spring, traded the roller for stock. Thinking back I should have dumped it sooner than I did.

I deal w/ both of these people. Dan is my yamaha man & Duane is my polaris man! Not that Duane doesn't know yamis , he does, but he's more into mountain 4 -strokes than vipers. Dan is excited to make yamis run! These guys both sell nearly the same products & know each other personally.I'm still waiting on a 52/48helix from Dan so make sure he has 1!!maybe he's got some in kit form??my 54/50 works great w? H.H's but I want to play!!
