Would you say 310f is a high engine temp? The only info I got was someone with the same bike getting 255-275f. And I cant really find what this bikes max temp is

I just rode this bike for the first actual time on the road for about an hour. Temp never got above 320f and stayed more around 305f while riding and its about 90f outside. Any help would be great

So I got everything running good but I just want to know what you think is a high engine temp and if the spark plugs look lean. After riding the bike for 20min and giving it some juice, the spark plug sensor is reading about 310 when its 88F degrees. Using a laser temp I was getting about 290...

I thank you for this. I actually plan on bringing the bike to a shop possibly to get this all setup. I want to make sure I set the valves correctly and have someone fiddle with the timing as well. The bike right now has a hanging idle which could be caused by a vacuum leak, valves, timing, or...

I would agree with you. But the original sprockets look pretty good. The bike only has 5000 miles. I know it'll cause more wear on the chain and sprockets. But honestly if they get me through the season, im fine with getting a proper set in the winter. Im more worried if the 530 chain side play...

Ok. Now I did already try a EK 530 chain and when I set a portion of it on the rear sprocket, it could shift side to side. No forward or backward movement tho. Im just asking cause it seems this sprocket is between a 525 and 530 width. The original chain has no movement any direction and seats...

So I got a 1982 Xs400 Heritage. The current chain and I would assume original one on the bike now is a DID50DS. But I cant seem to find someplace to buy a new one anywhere because its discontinued. I have also tired finding a DID50HDSS but still no luck. I have seen from googling that people say...

Just got the package today. It fits thank god. Thank you for the help.

It will arrive Monday, ill let you know

I had 15w-40 in the bike before just for winter test runs. Decided to go ahead and buy Valvoline 20w-50 motorcycle oil in for the warmer temps now. But once I start the bike and it runs for a couple seconds, the oil becomes pretty foamy. Ive done some googling and what I have found is it could...

Alright, placed an order. Lets hope

Ya now im just confused. I just looked at Yamaha Parts House and its the same thing on there as well. The cap is listed as (1H21118600). But they also only have the heritage special under the 1981 list.

Its a SOHC 1982 XS400 Heritage Special. I have resorted to using the god forbidden JB Weld. I let it dry for a couple days but it broke again once it was turned a little past finger tight. Im going to try again but just go to town on the inside surface scuffing it up to see if that helps. Once...

I am just pissed but I need your help. So I broke one of the valve inspection caps on accident. So I went on CMSNL and looked up a diagram to find which part I need to find and purchase. Well on the website, for a xs400 1982 Heritage, part 15 is the product number (1H21118600). So I found one on...

Thanks alot. Ill go ahead and buy the timing light.

Ok so I just went and checked and I am a little confused. First, I do have one of the screws to hold it in place(Top Right), but I do remember it did only have one to begin with so I will get another one. Second, I followed the manual on setting up timing for the cam and I do believe I did that...

Ok thank you for that. I will reply in a little bit with an update

Sorry I actually cant figure out what this is exactly. I think its the breaker from what I have read in the manual but at least for the SOHC manual, it doesn't look like it. Anyways, Im putting the engine back together and this is the last thing I think I might have to time correctly? I didnt...

Ok thank you

Back again to hopefully ask one last question so here we go. In this video here (LINK), you can see the piston has a fair amount of side to side play. It does not have any up/down or angular movement. I know the piston wont move like this in the cylinder, but from previous questions I have asked...
