I've heard rumors of these jugs having problems cracking and the same with the sleeves...are these worth picking up used or just a waste of time? I don't mx or drag race much. Thanks for the input

Yeah I had one of the 1st Pro-X 310's that CT put out and I had nothing but problems with it. The 1st cylinder leaked coolant out of the head because it was a poor casting(full of pin hole) Allan took that one back and then the 2nd one he sent me the intake part of the cylinder cracked along the wall where the reedcage bolts in and it started to suck air there. I personally would buy one of his new kits that comes with the Pro-Design Coolhead if I was going to get another one. Something to point out though is that LRD is claiming to get 2 more HP out of a resleeved stock cylinder (310) then they are getting out of there Pro-X setup plus the ring and piston life is alot better on the stock cylinder. Hope this helps.

 

I ask because I have the chance to maybe pick up one of these jugs that needs a sleeve for cheap...as in around 100 dollars...

 

For $100 buy it. If u don't want it i will let me know i will buy it for my open bike. email me or u know where u can get a hold of me and i will tell u more on what to look for on them cylinders. If i did that in the forum it would take all night to send it.
