DT1 clutch from hell
« on: November 03, 2012, 04:29:34 pm »
Hi guys I have a DT1 with a clutch that Arnie would find hard to pull and after breaking my left paw its now too much . I know its only on the start line but this clutch is a bitch , Any ideas ? what if I take out 3 of the springs ?  any help would be appreciated . Iain

Weld an extension on the little actuator arm about 10 mm so there is better leverage, wont hurt the cable pulling on a slight angle (YZB's had this done at the factory....you can still buy them new off evilpay but expect to pay around a $100 for one). Also, dont use the cheapie lever sets, you might have to muck around with diferent ones untill you get it right. YZA's are a shocker std aswell.

The last time I looked the GSXR was made by Suzuki. Are you sure you don't mean XS650?

Sorry to burst your bubbles boys but the it's a falacy that TX/XS 650 actuators fit...I bought one the other day to see because nobody could say 100% they fitted...YZA/B (and Im guessing DT/RT's) have  3 splines and the road bike has 4!!!....obviously the roady has a bigger clutch so was made with 4 splines to spread the love...its also alot longer in the spline and where the cable picks up....hopefully Ill have my new clutch actuator covers ready soon. Cheers big ears.

Joan I too tried the steel XS650 actuator and also found that it was a no go. I got excited and looked up the GSXR Suzuki version on eBay just in case Armada was onto something but it's nothing like the Yammy unit. Until someone comes along with a repro version that doesn't split the first time we pull in the clutch, we're stuck with what we've got.

I think mine has the rd250 one. The pull is steal Nd the come with the female which us plastic. Wen you drop a chain it took out he old female side in the cover, so it was cut off Nd the new plastic coil bolts straight on. The new steel helix mates with it as there a pair and it works a treat.

You've outdone yourself this time Freaky ;D ;D ;D. I'm just heading down to the preschool to see if a toddler can decipher your post for me. ;D

I've managed to translate it enough to read that Freaky reckons the RD 250 actuator fits. After shelling out for an XS650 actuator after we were told that they would work and finding that it didn't, I'm a tad wary of trying this until someone can verify that it fits. Here's what the RD setup looks like, suspiciously like the XS650 version :-\........................
