Hey guys, I pride myself on working to solve problems on my own. But somtimes you need a little help. Thanks for all you guys!
My problem. I did the 38t conversion. Went pretty smooth. Reinstalled the rear tire, everything seemed to line up fine. Tensioned the chain and rode. Chain got lose, loosened the axel, Tensioned the chain thinking its just normal chain settling in. Now I'm perplexed.. I have to adjust the chain every time I ride. I just cannot get the axel to torque down enough, it's not binding on the swing arm!.
My only possible problem is that I miss arranged the axel, spacers and washers..
So to my fellow ace 750 riders.. Can you take a photo of the exhaust side and the chain side of the swing arm. I need to see the install order. I looked at blow apart diagrams.. You'd think the axel and swing arm would be on the same diagram.. No.
My Order..
Axel, chain tensioner over swing arm, spacer, wheel, spacer, tensioner over swing arm, washer, nut.
Your assembly order sounds right.
The axle nut is meant to be torqued to 69 ft lbs, at that point everything should be bunched up tight and if you go beyond that the brake will complain in use. (Don't ask me how I know this)
If you can't get to this point, maybe the collar dropped out of the driven flange as you were reassembling the wheel.
Take a look in the Honda Shop Manual, it shows all the bits and pieces.
I just took a look again, it matches up with the images.
I can torque it up to 69 no problem. So I think I need to take a chunk of time this weekend and rip the backend apart... I'll keep you posted on this... Baffled here..
No extra parts laying on your garage floor? I think after I did the switch i had to adjust maybe 2-3 times over a week and then it evened out. Not an issue with your tensioners is it? maybe one stripped and isn't holding? Maybe mark where they are and make sure they didn't loosen after you get back. I think the axle bolt would still keep it tight but you never know.

So tonight, loosened the axel, adjusted the chain to. You 3/4 play, torqued the axel to 69. Then I tightened the tensioner to make contact with the adjuster so that if the axel is slipping, it can't move forward. I'll ride it tomorrow, by the time I get to my shop, it usually slacks, if it doesn't make I'll have fixed it.... Fingers crossed.
And yeah I've tried the 750ace specific forums... The 3 or 4 regulars (me Included) didn't offer much...
Excuse my ignorance, what do you mean by a classic one?
And I'll keep an eye out, but I'm sure you know that around here bike prices are 25% above what they are worth.

Well that seems to have done the trick. I guess the axle can slide a bit when torqued down.. I think What was happening was the tensioners bolts were backed off from contact with the tensioners , this allowed the axle to slide forward when releasing the throttle.
How this happens, based on my observations, when we release the throttle , the back wheel is now spinning the engine faster then it does at idle... With the tensioners play this drag would pull the wheel closer ( the counter clockwise rotation would allow the bottom of the sprocket on the wheel to pull on the front sprocket) The top of the chain traveling on the top would go slack and slap the frame and chain guard until it caught up, then it would repeat.
So by locking the tensioners to an absolute minimum travel position, your fix the problem... maybe it's not even a problem and I just didn't do it right the first time.
