Need help - interchangeability of 305 motors?

Susan · Post by **Susan** » Fri May 04, 2012 2:06 pm

Hi - I haven't been around much, but I'm still in a holding pattern while I look for a motor for my poor dead CA77.

I thought I had one - on ebay but local - but when I went to see it I saw that it was a Shriner's bike, being sold by the original owner's son. Would have been a crime to part it out.

Can anyone tell me if 305 motors are swappable? I have a line on a Scrambler motor - but I'm not sure if it would be straightforward or more trouble than it's worth.

cheers

wait for a dream motor, the dual carbs/aircleaners/etc will make it difficult, One will come up for you!

Good luck,

Paul

Susan; what, exactly are you looking for? do you have an engine at all? do you just need parts? anything can be rebuilt and most of the used stuff out there needs just that. plenty of sources to rebuild yours. used/rebuildable dream engines are common as dirt but you will be shocked at what it costs to go through one.

Susan, did you ever figure out what happened with your old motor?

I agree. The good thing about finding a dream motor too, is that they are generally in pretty good shape. If you find one in a bike it's also more likely to be free because of the single carb and the way the frame covers it. I think more "good kids" bought the dreams as they tend to not be so modified and beat up as scramblers and superhawks!

Okay, thanks for the info. Never having torn into any 305 other than my CA77, I wasn't sure if it would be a simple swap.

So the old motor - I got a loud clunk when taking off from a stop light in 1st, and she was frozen up from there.

Turns out it was a screw backing out of the Sprag (starter) clutch and coming into contact with the case. But when the motor was split, it became obvious that everything in there is pretty ugly. Roached pistons, chains need replacing. I consulted with a more experienced mechanic on it, and after looking it over he was of the opinion that it was going to cost a bundle in parts.

After mulling it over for a while, I decided that the best option for me right now (I am renovating a house and working a full time day job and just don't have a lot of time) would be to find a running motor - or at least a motor with good parts. If I didn't have any other projects (or had some time on my hands), I'd at least price out parts for this one, but I just don't see that happening any time soon.

This local bike was a beauty - still had it's Shriner's medallions and all. If I thought I could have sold mine easily with no motor, I would have snapped it up. Too many bikes right now though, no space even for one more.

Susan,

Rebuilding a motor is never cheap of course, but it might be an idea to chat to LM and see what he could do for your existing motor. If I were you I'd offer to send him pictures of what you have and what seems to be worn out so he can better assess it.

I haven't spoken to Ed about this offer I'm making on his behalf, but I know he can tell you if it's a good idea or not.

How bad can it really be in there? Was it running fine before the screw came loose?
