Ok that’s I’ll have to keep a eye out

I figured out the problem it was a exhaust leak the first thing I should have checked but at least my timing chain and valves are adjusted now

Do you know where I can get some good points iv called Yamaha dealers and the said oem points are not available anymore or are china points my only option?

So I reset my float hight to 24 mm and it runs 100 percent better both mix screws at 2 1/2 turn out thanks so much for the advise I have one more question is it normal to here ticking comming from then head on both sides or do I have to readjust my valves?

Yup that makes sense to me I’ll give her a try tomorrow it has stock air filters and full length straight pipes with home made baffles to calm her down a little and to give some back pressure I did go up one size pilot jet. I went up one size main jet that was to much she was flooding out

Ok I think I ruled out spark issues I filed the points and swapped cylinders and runs the same and swapped cylinders with the coils. So next I’ll pull the carbs and reset the float hight to 24 mm. This thing is making my head spin it acting like it floods at idle and is running to lean running...

You are right I just want ugly loud look at me but I want it to run good so is is there like a glass pack muffler that will give a just enuf back pressure to run good?

In case anyone looks at this thread in the future with the same problem I split the case and found all the dogs busted off third gear

Ok I’m sure this has been asked before but I have a 1979 xs650 and I’m gonna be running factory style air filters and straight pipes and I’m sure someone else is doing the same so I wanna know where to start with jet sizes

Ok guys I got her apart and found the problem and now I’m wondering what number of yamabond to use to glue it together with?

What is iirc

Ok thanks a lot guys do any of you have a diagram of the sequence of removing the case split nuts kinda like finding Waldo trying to find them numbers

So I’m going to split the case to just work on the transmission and I want to leave to top end intact and I wanna know if it’s possible?
