the metal in the oil on mine is not that bad its just a lil bit a few specks so im still leaning toward the lifters, i hope if not the 91 motor on my 86 is going in it, or im going to take the front end of the 91 and put it on the 86 either way i am going to ride this summer. if it is a rod it will be a very steep learning curve on these. The biggest cycle motor i have built was a honda cb 550.
the reason i was going to just get the kit is so i dont have to go order them for my other 750 when it needs them you guys know better to have the parts when stuff wears out. a little prier planing to limit down time for both bikes
well to day i am going to tear her down and get the specs. and order the shims from suzuki hopefully they dont take 3 weeks to ship like they did with my lt250r top end. well guys u have been very helpfull thanks
ok so i just got done checking valve clearances. cyl.1 in. .15 .15mm ex. .17 .22mm ,cyl.2 in. .18 .17mm ex. .17 .25mm cyl.3 in. .10 .15mm, ex. .20 .17mm
cyl.4 in. .16 .16mm ex. .23 .24mm only 1 shim is at service limit then i looked at oil that came out of left side cover and this is what it looks like so what u guys think?
Motorcycle: (3) 1st gen 750's; (2) 1st gen 1100's; 90 7/11; 05 RMZ-450; 83 Honda CB1000C; 78 Yamaha DT 175E; 89 HD 883 Sporty; 98 KX250; 85 ATC 125M; 04 Polaris Predator 500; and a few kids quads.
Re: new project
First off, you don't have lifters in that motor. Secondly, is it just the photo or do your camshaft lobes look brown and scored? It looks to me like the lobes on your cam have the chrome wore off of them, and if so, you can bet the rockers (perhaps what you refer to as lifters) are wore out as well. How many miles are on the motor? Judging from the state of the rest of the bike, I'd say it suffered a lot of neglect in the hands of previous owners and you might have to replace the cams and all the rockers.
I'm with the government - I'm here to help.
yes sorry long the rockers, as for the cams yeah they are a bit messed up, the guy i got it from said it had 21,000 or 24,000 miles on her. what if it was synthetic oil with shift modifier thats what the oil looks like when i change the rear end gear lube in my mustang.
and 89gsx u wouldnt want this solo cowl anyway kinda jacked up been fixed a cupple times
hey long_ good eye. the guy i got this bike from needs to be slapped. well any way i am most likely going to take the hole thing down to suzuki and have them check it out. hope i can just get this motor going relatively easy and not have it cost me a arm and a leg. well wishful thinking lol. are there any aftermarket cams and rockers still available? link would be great been looking all day and have not found any. thanks
so today went to start pulling the motor. drained oil and no metal at all in oil from drain plug. so i am just waiting to get cams and rocker. will update when i change out cams and rockers thanks to all
Yes I got it figured out. Unfortunately it was the #2 big end an the cams, rockers an valves on the #2 cylinder. I just scraped that motor an found a replacement from another 91. Sorry took so long to reply had a mess of the past cupple years. Crashed my 91 after replacing the motor an the misses was pissed an made me sell them both. Then she left. Should have kept my bikes.....thanks for all the help you guys offered
