Will running a Toomey hd spring be any harder on a transmission than a stock, seeing as how it probably doesn't allow any slippage at all? Just curious if there is any relation between tranny life & clutch slippage.
-
I've got a quick question re: a Hinson basket:
Do these require any additional parts when installing? Or, does the basket just replace the stock basket?
I ask because I have one I took out of a spare motor I have and will be putting it in my (now) running motor this weekend. The stack of pieces I have with it from pulling out of the other motor seems to have a spare washer with it. When looking at the exploded view in the manual (page 3-49 of the 88-92 manual) I've got two of the washers that go between the basket and the "Clutch Sleeve Hub" It could just be a spare from another stock clutch I sold however, the weird thing is that the back of the "Clutch sleeve Hub" where the washer touches has a worn in mark of a 4 sided semi-star shaped thing. I can't find a washer with these parts that looks like that, though and it's obviously not shown in the exploded view.

I really like it holds well.
Ya,they are pretty sweet.Had them in every bike I,ve needed to upgrade/replace.The springs alone are a big upgrade.

the ebC clutch springs that were heavy duty in your dirt digger pack are a copy of 85 86 spring I compared them this evening when I took me ebc clutch out to put in the barnett at kevlar dirt digger
How are you liking that Barnett clutch?
-
I use Barnett hd banshee springs with ebc zilla clutch plates. It is a tight fit getting the springs in but they do fit. It is surprisingly easy to pull. I'm hard on clutches and often slip the clutch to get RPM's up when climbing a dune. So far they are holding but I probably am burning thru plates faster than normal dirt or mx riding. So far I'm happy.
-
This should be a stickey some good info in this thread.
-
Also on a drag bike being able to adjust the springs will you adjust your power to the track surface. Some are very hard others are sandy.
-
what the advantages to tuning the spring weight? Heavier = more pressure? Stronger engagement?
Basically the more power you make the more likely the clutch is going to slip. Stiffer springs will make it less likely to slip. The trade off is the stiffer the spring, the harder it is to pull in the clutch lever. Chris having 73 pound springs on his drag bike, he doesn't use the clutch that much. On a trail/dune bike I think the 73 pounders would wear your hand out in a short time of riding.

Thanks Chris good info on the other springs .
-
sorry i dont. i got all these springs for my clutch on my liger motor so i can tune the primary pressure and the lockup weight.
-
Chris do you know what the load is on the Barnett springs that come with the Kevlar dirt digger clutch are . Also the ebc springs that come with their clutches for the lt250 87 to 92 models
-
just checked my springs:
stock zilla: 40#
barnett zilla: 53#
85-86 250r: 60#
barnett banshee: 61#
toomey banshee: 73#+
-
i use toomey banshee springs in my liger. they were the largest # of pressure at installed height. thats what i got back from kevin when he made the first lockup. ill look and see what the 85-86 springs are at. i know my banshee were well above 73# a peice at installed height.
-
I heard they work well to how do you like them yourself. This will be good info for others later. Banshee spring 85 86 quadracer springs and yz 250 springs have been used so far.
-
I run Banshee springs, that's why I ask.
-
I dont know but I have heard of other guys running the banshee springs.
-
Is there a different between using Banshee clutch springs and 85-86 LT springs?
-
the ebC clutch springs that were heavy duty in your dirt digger pack are a copy of 85 86 spring I compared them this evening when I took me ebc clutch out to put in the barnett at kevlar dirt digger
-
Ill just stick with my HD springs but thanks for the info.
-
Well if the 85 86 springs are good enough for a zilla they should work good in a 250
-
I see I see. Ive always liked the HD springs myself but I havent tried any others.
-
they are stiffer 85 86 Springs but I really thought about using the ones that came with the Barnett they felt stiffer then the 85 86 springs did.
-
I have one engine with an EBC dirt digger and the HD springs. I also have a TUSK clutch with the HD springs. I like both of them.
What is the difference in 85-86 springs? I would like to understand what makes them sought after instead of just putting them in because I have read it on here.

Which springs you using rainman
Using the springs that come in the Barnett kit.Stiff enough and it takes a beating from hard running MX to 2nd gear launches off the line.
-
Just call Barnett and ask them for a six sprin pack of that part number. That's what I did.
-
Which springs you using rainman
-
I,ve used DirtDigger on all my stuff.No issues at all.The billet baskets really are the way to go if you need to replace it.I,m running a PE basket and barnett kevlar.
-
Clutch is pretty old. I cant find the 6 th spring everyone on ebay is selling 5 of the 85 86 springs
-
The Barnett is awesome in the ole 86. It lasted and did it take a fricken beating. Wow.
-
My 250 has a stock. Clutch and heavy 85 springs my 500 has a Barnett with yz 250 springs. Neither have ever slipped. Unless they were worn out.
-
Do you use the 85 86; spring gillio and bad moon i have a hinson basket its in good shape and got al brand new magic basket
-
I run dirt diggers on my big bores, never had any issues to date.
-
Look at your basket, the fingers might be worn. If there not to bad you can file them down flat. If there bad get a billet basket. The grooves in the basket fingers can make them slip.

Barnett dirt digger with the 85-86 springs.

I have 91 lt 250 and have a ebc clutch which I increased the power of the quad now it seems to be slipping. Runs great on grass but slips on pavement. Is the Kevlar clutch the way to go. I was thinking of Barnett kevlar. So please chime in
