So I got the bike back together, haven't touched the valves or the carb. It runs great with the new exhaust. I am really impressed what a difference that mikuni and exhaust made to the bike, it makes cracks and burbles now.

So I got my sprockets 16/44T with a 130 link chain. I have to take 5 links off correct? +1 front, -6 rear to make 5. Thanks guys.

The bike is really turning out nice. Will post pics of it finished next week when I have everything on it.

NO!!!! measure first.

on my hawks went to 16/45 took out 2 links fit perfectly. measure, measure,measure before you cut! also position rear wheel about middle of adjustment range before you measure to leave yourself some wiggleroom

Gotcha Boss, will do tonight! Thanks for the reply!

Going to do the valve adjustment this weekend and tune the carb. She's sputtering at 3/4-WOT or at the top of the rev range, seems like a lack of fuel. I think it needs a bigger main jet and the jet needle needs to be shimmed up. Let me know your thoughts. I'm at 3,600 FT above sea level. It is a mikuni 30mm. Thanks guys.

Do you have the stock jets in the mikuni? Not sure at 3600FT but I would assume it is running lean.

take a few minutes and pull the spark plug for a looksee at the color..darker= richer, your are looking for a light tan color.

It's running stock jets. It runs well at 0-1/2 throttle. But past that, it's running lean for sure.

That carburetor comes with a 100 or 105 main jet. You may want a 115 main, and a 20 or 25 pilot. If the main is way too lean, the needle can't compensate for it. That is why it doesn't run well to 3/4 throttle. Raising the needle will help some until you can get a new main jet. But it is not a permanent fix.

jet321 · 07-17-2016, 12:47 AM

I picked up a 115 and it was running way too rich. I'm going to try a 105 or a 110. I also shimmed up the needle and it may have been to much. I'll keep tinkering with it.

pcspecialist · 07-17-2016, 01:45 AM

You shimmed up the needle? I thought you said you got a Mikuni? If you are using the stock carb, 110 is big enough even at sea level. A Mikuni needs a 115 at sea level.

Maybe he just moved the needle up with the clip.

jet321 · 07-17-2016, 11:48 AM

Yeah I shimmed the jet needle up with a washer. The 115 seemed to be to much. It was choking on fuel. I'm out of town but I'm going to keep trying to play with it when I get back. Also what's the marking for dead top center for the motor, I need to do the valve adjustment.

It will be a line with a T next to it.
