camshaft

Alright I need to do something. This 2-into-1 turnout I have sounds like absolute s***, and either the baffle is completely rotted, or it never had one to start with. Either way it’s not a serviceable part, so it’s junk. I’m thinking of going back to stock headers (Anyone got a relatively-clean...

"Working From Home" has left me alone in a small room with my computer for more hours than I should be, and with a wife and kid running around the house.... let's just say looking at skinny girls is right out. So I dusted off a Windows98 virtual machine and an old copy of Dyno 2000 and started...

Hi all! I have an XT250, year of manufacture 1983, which needs a new camshaft. Apparently, there are several oem camshaft versions for this bike. US, Europe, Switzerland, etc. And the prices vary wildly as well, some US versions being cheapest. So now my question is: Will a US market oem...

Anyone with any advice or knowledge of this sound would help. I have found a video/thread that had the exact sound that I have on my XS650SG. In the thread it was never solved or finished back in 2016. Again this is not my engine in the video, it just has the exact sound that I have. I...

Stuck on adjusting the valves. Well Ive gotten myself into another pickle before Born Free 11 last week. It started with just getting the bike finished to overnighting a camshaft kit and rocker arms from mikesXS. I have a 1980 Yamaha XS650SG that currently started ticking at the top. It was...

Hey, everyone. First off, I want to say this forum is a tremendous resource and I am very appreciative of all the info you guys provide. That being said, I am looking for some guidance. Ok, so here is what I am working on. Please disregard the seat/sissy bar fitment and the messy garage. The...

I have been re-assembling my bored, rephased XS650SJ. I have hit snag while degreeing the cam, and want to ask your advice. Background: Valve job, head re-surfacing, and boring (to 700) by Hoos. 447 crank and cam 277 rephased by Hugh's. New pistons, rings, cam chain, cam guides (both)...

Sup guys been a while. I took my tx650 engine out and apart replaced rings,valves camchain guide and gaskets from the versah gasket set. When I put the camshaft in I placed the punch mark on the right side (threaded part on the right) of the engine at 12 0'clock relative to topdeadcenter. Its...

I'm trying to replace my oil seals to fix an oil leak coming from my left side camshaft cover where my electronic ignition is. I took off the outer cover and the ignition plate but I can't seem to get the inner casing off. I'm wondering if the engine needs to be at TDC or something because it...

Will a camshaft for a 1977 motor fit a 1975-74 motor?

i have an xs650 that i rebuilt the engine on and am trying to retake my steps on what i did. the bike runs and power band seems correct but the pressure out of the right exhaust seems stronger than the left. could i have possibly installed my cam backwards? or is this impossible? i have a boyer...

I've found specs on the 447 cam at http://www.650motorcycles.com/isky.html What I'm confused about is whether I.V.O means intake valve opening or intake valve open. I guess I'm confusled because it mentions that it was checked at zero lash then it lists various lashes?... Maybe the dude...

Just finished putting the top end back together after new pistons and rings arrived. Withe the cylinder head in place and the three bolts put in (but not torqued) I put the pistons at top dead centre lined up with my new accurate mark on the PMA. I slide the camshalft through the cam chain...

I received my pamco ignition from Mikes XS yesterday. So last night I Got everything ready to install and the bushings did not go in easy at all.. I have a 1980 and at first glance the bushings seemed a little too big. I first started on the left side. Cleaned out the inside of the cam hole...

Hey there. Need to replace my camshaft on my 1980 xs650. Anyone know if a camshaft from a 1979 will fit on a 1980? Is there anything I need to know about changing this out to a previous year?

This is my documenting my experience with the PAMCO installation from a newbie perspective...hoping that it helps others....I will be updating as I hit questions and hope that I can get answers and to a final state...aka...running with PAMCO. First things first...1981 SH Heritage, mostly...

My bike is an '80, How much does my cam differ from a XS1 cam. Also, what is this shell cam thing I'm seeing here and there. I'm asking bc I'm considering a rephase and I'd like a hotter cam to go along with it. I think I do anyway, I haven't ridden a 650 before and mine probably wont be...

Ok guys, let's get started. First - Un-screw the phillips head on the out side of the rocker top. After thats out of the way, now you have to punch out the guides for the alignment rods to access the rocker pivot slug. For this, i used an 8mm socket. It was the perfect size...

Does any one know the OD and length of the advance rod bushings? These are the ones pressed into the camshaft.
