AlwaysBroken04 Posted November 7, 2013 Report Posted November 7, 2013 Had my cylinders bored .040 over and the machinist chattered the left cylinder and had to put a LA sleeve in it (the right side was just bored no sleeve) using a temp gun I noticed the left cylinder runs a little hotter than the right...Is this from the sleeve or tuning?

joey83 Posted November 7, 2013 Report Posted November 7, 2013 At an idle? How much hotter? Carbs synced? Quote
trickedcarbine Posted November 8, 2013 Report Posted November 8, 2013 You should have made that machinist pony up the 200 bones for another set of cylinders and pay for them done by a competent machinist. Quote
n2otoofast4u Posted November 8, 2013 Report Posted November 8, 2013 So you have one cyld with a sleeve and one without? Are they the same bore size? Quote
twosmoker Posted November 8, 2013 Report Posted November 8, 2013 im with carbine when the machine shop did my cyls he bored to far over and couldn't hone finish them correctly I blew up, they payed for a new set of prolites next size up, think of it like this your paying good money for him to do the work for you if they stuff up they need to fix it or compensate to fix the problem for you Quote
Starwriter Posted November 9, 2013 Report Posted November 9, 2013 Years ago, I had a machine shop bore a pair of RD400 cylinders for me. The reed cage mounting flange hangs down below the cylinder base. They didn't block the cylinder up to clear. They called me up after they bored the 1st one way crooked and told me that it didn't clean up and that I needed to buy bigger pistons. I went down and picked up the cylinders. When I got back to my shop, I realized what they had done. I went back there with my machinists square and proved to them that the bore wasn't square with the base. If it could have been bored straight, it would have been on the last bore. I made them buy me a brand new cylinder from Yamaha and also pay my builder for the porting on it. Quote
KaN Powersports Posted November 9, 2013 Report Posted November 9, 2013 LA Sleeve shouldn't be any hotter than a stock one. The only place that would apply is if it were an aluminum cylinder (Nikasil).. Then they wouldn't be boring it in the first place:).. Check your tune. Now, with all of that said there are situations where this applies-Like the thicker skirt repair sleeve for the lt 250r, or the sleeve inside a sleeve on the CR 500- I do a LOT of resleeving, and I have to say it's not the sleeve's fault your cylinder is running hot Quote
