the tightness is supposed to be real tight by hand when u first get it...so u get a good fit imbetween ur sleeve and piston during break in. U could try loosening it up by hand. I used to lube it up wiht some tri-flow through the glowplug hole. Heat it up with a blow dryer and then worked the pisyon up and down via the flywheel. then when i started my engines they came to life easy.

rapid roy so how far does ur car need to travel inorder to shift now? I dont really like to run 2nd gear in front of my house but it seems that the it engages late...On track i cant really noticing it shifting cause i am paying attention to the other cars and the track ahead.

I tightned the adjustment screws all the way down, then tightned the ball bearing down till it touched, then backed it off just 1/8 turn. Then I started adjusting for the shift point.

If my understandings right I should be able to get the clutch working and not need to loosen bolts excessively and add loads of spacers b4 the thrust bearing unless I have defective parts or theres summit the manual didnt tell me about.

Hey man, did you get this resolved???
I was having a similar problem and I found out the the 2speed clutch was not assembled correctly...I took my 2speed clutch apart and rebuild it, now I have some play around the shoes and I'm getting the throttle response I was missing AND I'm shifting into 2nd gear!!!
So all this time I've been screwing around with the clutch on the engine, it was in the 2speed all along...what a PITA!!

Hey.
Does R40 uses sub c batteries? How much it gets weight? Instead of it, can we use aaa cells?

Dunno why you would want a sub-C in there?

Wow , yeah my d3r was pretty damn nice on the inside. Probably the most worked over motor ive seen. My nova was nice but it still had a lot of the rough pourous metal in the case and certain areas. While the d3r is sharp all over.
How did you get that thing? Now im super jealous , lol.

I dont think you can get the 2005 yet Im still kinda clueless on what to do with the brass pipes. They kinda got loose after I pushed them down a little. I kinda dont like that jiggling around free. Another thing though be careful when tightening I kinda made some stress points. And lucky ol me they dont really readily sell the lw 2 speed shoes in the US. Whats up with that crap?

The main point of my post is "look out STS is developing some very cool stuff which should be arriving soon"

Is there anyone out there that makes a CF front bulkhead for the R40? I want one bad cause I'm tired of the one on there. It just looks out of place.
