Making progress on my sons 1000

[sonsabiker]

Finally got carbs rebuilt and found a interesting problem I wish I had taken pics before he went to local dealer to get new main jet. I've never seen a main jet in two pieces,I found it laying in float bowl with the threads broken off. When we went and picked bike up the PO told us it smoked out of the number 1 cyl so I figured it was something more serious and when we got it running it ran really rich, so thats when I pulled carbs to rebuild them. Never thought I would find that. Owell it's fixed now, we're still waiting on o-rings and intake runners to come in, went and picked up a motion pro manometer today so he'll be all set up. I wish he would decide if he wants a 4 into 1 exhaust or not before I put it all back together and sync it.

Aha found it!

I'd be checking everything on the bike carefully

Anyone who could snap a brass jet in half is capable of all sorts of destruction

You should check the valve cover bolts to see how many are stripped out

If you are doing the repairs you should get to make the decisions on the pipes.

Short story.Cleaned/rebuild carbs on 1978 CB750F.About !00 mi or so..mid-range acceleration,very poor/stunble bad.remove carbs,look and find big brass jet lying in bottom fuel bowl.I was so worried about snapping brass ,i erred on w/too light on snug torque.Didn't have torque wrench back then either. Q.Smoke was what colour,mechanic say?

[sonsabiker]

Come to think about it he didnt say what color smoke it was, it wasn't oil but sure was rich. I still need to go through valves so everything will be checked thoroughly plus I think the threads for the center pipes are stripping out since they don't seem to want to tighten up, man I hate aluminum. And he can deal with stock exhaust for now. He needs to get used to riding something bigger than a scooter before we start jetting and doing mods to it.

Lately been riding gravel/sand back roads(I live on one).Riding 250cc KLR to keep skills sharp and to slow things down a bit,good to hear son have scooter experience and such.Your desire for good/proper approach in venture/project very wise.

[sonsabiker]

He thinks I'm going to getting it back together so he can ride it before winter but he'll get over it I might just pull engine out and go through it just so he can have a safe and memorable ride. He can't take safety course till next spring anyway since seasons almost over and all classes are full so I'll just make his life miserable and happy at same time. Good things come to those who wait, and he'll be much happier with being able to ride all next year and proud of what he has instead of calling me to rescue him.

Stripped or snapped exhaust bolts are a common problem

Careful drilling and maybe a helicoil will solve that problem

I'm sure you'll find more stripped bolts as you go along
