2009 cvo 110 Ultra Woes
« on: March 29, 2019, 10:41:38 AM »

Well gentlemen, After reading cam horror stories on some of the forums I finally went with the ole redshift 587 installation. Low and behold the se255 failure was in the works and she only has 41k miles. The inner cam bearing rollers on the rear cam were flaking and had obvious witness markings on the cam. While doing the cam I had noticed the oil leaking from the rear cylinder at exhaust valve area that had been seeping for a while. Welp after a few hard runs after the cam install I heard a noise that got louder while accelerating. When I got back to the house to check it out I looked while throttling and saw the head gasket blew. Very disappointed I pulled the top end apart and noticed the rear cylinder area where gasket leaked appears to have slight sleeve liner abnormalities.So now I'm at the crossroad again. Big bore kits alone are over 1k. I've already invested in the cam/lifters. Think I could have the existing cylinders repaired,bored,and go with a 10/1 piston for the cam and do a basic valve job? Or spend another 2k and do the SE 117? I'm starting to think its not worth it!

I suggest a valve job, with heads resurfaced and new guides. If the liner has moved I would pitch that cylinder. Buy a new one and bore both over to first oversize. The cam choice will dictate optimal compression and there's nothing wrong with that being set at a lower than bleeding level. What I am recommending is a longevity move. If performance increase is the goal that changes things a bit, just more money. Any of what I proposed will require a full dyno tune with a flash tuner such as the tts.

Solid advice! :2vrolijk_21:  Be sure when you have the barrels off to check the rod bearings for binding!

If on a budget, might be able to pick up a set of used 110" jugs and then bore then out for 113" pistons.

Have you changed the lifters?  If not, then they are well overdue

Thanks for all the input everyone. Now I'm at another crossroad! I purchased a 113 big bore kit that is rated at 10.7 compression ratio with a 0030 head gasket. Looks like another cam change and don't even have 50 miles on the rs587's. I'm a glutton for punishment. Opinions on the redshift 576 or 577 based on experience would be appreciated.

I'm thinking the se259 would be the one to use with this compression ratio. The 577 is kinda pricey too for a cam 399.00. Woods cams a cheaper than that! Anyone want to chime in on the 259?

Use the 259 at 11:1 and it is great. 10.5 soft out of the hole, again pipe matters.

Have you ever cut the domes down on the wiseco piston to accommodate the smaller cams (587)?  $$$$ haha
