Title: 2012 103 clutch slippage
Post by: JT Metal on July 19, 2019, 07:17:20 AM
Only in the top of first does this happen. Under hard Accel. Would an s.e. diaphragm solve this problem? 101/112 hp/tq. 25k redline shockproof
Let me know your thoughts.......

Depends, where did you put the shockproof?

25 k on 100+ motor you got your moneys worth. Now you got the excuse to install a primo or barnett and you wont be sorry.I also hope you dont have shockproof in that primary or why would you mention that?

Hahaha.......sorry. redline transfluid. I had shockproof on my mind.

SE spring will make a difference I did the spring and a SE clutch pack and haven't had any problems .  Bob

Alto Carbonite +1 clutch discs resolved that issue for me.

On top of that I added the SE VPC on my 124" (148 ft/lbs of torque) and I don't slip.

Thank you Doc. I am 20 miles from J&P cycles in Ormand beach, fl. Going to try and resolve this tomorrow. Not a lot of info on Alto. If there's an issue, They will sell me something else. Lol. I know.....it sounds bad.
Thank you Doc.

Hey doc......I was looking for clarification on getting started with install. Not very clear. I assume the thin shim & jutter spring are removed. And start things with thin friction then jutter spring (not clearwhich way it goes) then follow by friction then steel & so forth.

First small friction plate .second small spring plate looks like a bowl facing you. now alternate your frictions and steels.

the alto kit has 9 steels and 10 friction discs 1 more each than stock. stack ht is correct.

I know BUT your previous post says

QuoteFirst small friction plate .second small spring plate looks like a bowl facing you. now alternate your frictions and steels.

your use of friction plate is somewhat confusing, are you refering to items 3 and 4

I'm pretty sure I've glazed the clutches. Didn't want to just change the spring and open it back up again.
Maybe I'm wrong.

Top of first gear. Sounds like the back tire slipping to me. I get a little slippage in fourth or fifth rolling on hard at 2500 but just avoid that by shifting down and no problem.

FSG plate 37883-98 is replaced with small friction disc. concave plate 377884-98 is retained unlike SE clutch set both are discarded.  Hillside the aim 95 plate is a great set up except many guys dont have the extra bills for it. the other problem is for little guys the clutch pull is pretty high at high rpm shifts. Props to you my dyno guy says your heads flow the best he has seen and we use mackie and branch.   :up:

I have the stock plates, SE spring and SE VPC on a 140/140 117"... no slipping.

I understand stock clutches are a good choice. Alto clutch sets my cost $ 100 bucks and work great in all HP configurations. Win win
Title: Re: 2012 103 clutch slippage
Post by: JT Metal on July 27, 2019, 10:07:26 AM
Update.....took clutches out. Have to say the old fiber plates looked mint. I'm suspecting the diaphragm spring just wasn't doing its job. However I stuck the new clutches in and HD spring. So...let's see how that goes. I jumped on it a couple times without any slipping.
Title: Re: 2012 103 clutch slippage
Post by: JT Metal on August 10, 2019, 10:19:46 AM
Update: all went good. Well.......haha.   It is my opinion that my clutch friction was in very good shape & that my stock diaphragm spring just couldn't hold, weak or what have you. Save $130++ and try the s.e.spring first.
