Question my stock motor finally starting to feel good running pretty good but still not shifting I have leaned it out but I am fairly new to nitro but followed all the guides on here and basically wondering if it could be cause got the rtr and need to put stiffer springs and all that I have a bunch of upgrades for it but wanted to get it running well first and at point where I wanted more do all the suspension and all that but if I have to pull motor and work on clutch maybe just strip car and do full reset. What you guys think?

Hi mantis works so this morning I attempted to get to the clutch ran into a hickup and realized I needed a tool to get flywheel off I didn't have. I did replace the 3 part springs to 1.0mm ones it helped but I ordered tool will try that as soon as I get it. Also you are the guy who does rc shox website right? I'm gonna order the flo control gt spec pistons and the motor mount heard great things!! Is there a spring rate and oil weight you suggest? Thanks for reply as well really appreciate the help!!

Today I got the flywheel off and I installed the 4 shoe clutch and flywheel on my motor but now the bell is tight it spins but lot of drag compared to the old 3 shoe one it came with. Am I suppose to use a different bell with the 4 shoe? I also adjusted clutch 1/4 turn out on the center diff. But don't want to run it if gonna mess stuff up due to clutch being so tight.

Why would the 2 speed rotate gears only and not the outdrives???

Are you talking 'under engine power'? If that's the case I'd explore 'one way bearing' ......SHOT.....or in backwards.
If, with engine OFF.....you roll car backwards.....does that motion drive your gears.....?? That's normal.
Did you put some kind of lube other than 'one way bearing lube' on the shaft or bearing ??

I've seen that happen. I was told to gently wipe out 'one way bearing' and reinstall and I was also asked why I didn't know I was supposed to put a drop of 'one way bearing oil' on it. I thought a new bearing was ready to go but..... I ran a Kyosho car for 3 years without touching it before it died.
I've seen that more than once and it gets frustrating when it starts doing that on your race pit stops leaving the pits !! Get personal with your 'one way bearing' try gently wiping-reassembling. (order some one-way bearing oil)

Thanks for the advice. I am putting the V1 2-speed back in for time being. Never had this issue before. My Ofna 2 speeds (at least the cam versions) worked flawless and still do. I called Amain and talked to them about it. I stressed the idea if the one way bearing cuz to me that's the only thing other than the 5x5 pins which I checked and was goot. Amain gave me Paul's number at Desoto so I guess I will call them on Monday.

Do you remember if the trans clutch springs 'dropped' into the shoes without having to push them past 'friction' ? I had to use springs from another source because the kit springs were more like a 'friction' fit than easy drop in. I fought that for a long time. I know now to check for that interference and gently ream the shoe if necessary or use my magic springs !! Once you fix the bugs, you'll love that car. By working on it you'll get that 'symbiosis' !! 😎

I'd say 'BINGO'......it's good that you noticed that detail. Screws may have gotten tightened too tight and deformed springs to the point of 'hanging up' in their 'bores'. I'd replace springs and go easy on the 'tighten all the way in' part of it. Then enjoy a properly working transmission!! 😎
