I was doing a routine cvt clean-up and inspection a little while ago. I also installed a Malossi toque controller. My first one so im not sure yet if or how much it will help? The Cobra always shifted very well for a stock set-up but it cant hurt i guess.

The good news is my Malossi rollers are holding up really good in this one 8-). All i do is make sure i rub some graphite powder on them and dust a little in the ramps. Works great! You know you did it right when your rollers glaze with graphite Image .

The bad news is these cracks i found in the case around the main bearing :(.

There isnt any play in the crank. The seal is good. She runs good.
They could have been there since day one for all i know? I just saw them today tho :-/. Im thinking about cleaning up the area and roughing the cracks up and epoxying or JBwelding them to try to stop them from getting worse.
Anybody got any other ideas?

Yes....pull apart the complete engine and weld those cracks, performa leak test and "blueprint" that engine...You'll be happy You did :D

Ide love to but cant really have any down time with this scooter right now if i can help it. I think i will rough the area up some with my dremel and epoxy it as good as i can for now.

I understand.....then, make a "grove" over each crack using a cuting tool on your Dremel, the grove would help the epoxy or JB weld to "anchor" to the surface...

Thanks for the heads up on the cracks. I'll have a real close look at mine as it's had random problems symptomatic of air leak since hotting up the engine.

Arrrgh sorry! Looks like I inadvertently thread-jacked, but I got my wires crossed thinking the cracks were on the CPI. :oops:

lol :wink:

Interesting that the cracks all radiate out to a place that is reinforced. It would seem to me that if they were stress cracks they would radiate out to a weak area.

Possible that the cracks were in the die that the carter was cast in, and not the carter itself? Can you feel a raised "crack" or is it flush?

Leakdown test wouldn't hurt. Also, check for Kymco recall. There were issues with some cases from 03/04 models AIRC, but I don't remember the details. Kymco replaced the engines that were affected.

Good Luck!

Thats ok, i do that time to time myself. I like your CPI BTW.

As far as the cracks go, they are just lines left from casting. I guess i should have looked closer before posting :oops: . Before i cleaned it up they sure looked like cracks to me.
