883 to 1200 Ripper Kit

[hillakilla]

i think i may get away with my 42 and just reset the mix screw (capped with aluminum plug) since i have a paper filter and baffled 2-1-2 pipes.

Ill try shimming the needle first. If ive got mid-range issues ill get the '88 sporty needle

let 'er breathe!!!!!

Stock 883 heads with a 1200 kit makes a 1200 ignition module desireable. A stock take-off will work. You don't have to adjust the voes switch, just check it works right. A 45 slow jet, shimmed needle, 180 main jet, & adjusted idle mix screw should work. Replace intake and exhaust gaskets.

You want the 1200 ign. because the advance curve is different than the 883's. Good luck!

Valve Lapping

So Ive been waiting forever for my cylinder kit to come in. I guess they sent it to california accidentally.

Anyway I got the heads cleaned up and lapped the valves tonight. The exhaust valves and some spots on the intake seat have some pitting. Im not sure if this is severe or acceptable. I never noticed any weird power or compression issues while running it this past season. The combustion chamber did have a fair amount of carbon build up though.

I lapped each valve/seat for a total of probably 30 sec to 1 min lifting and tapping periodically.

Any thoughts?

[ThePete]

Never pulled apart a motorcycle head to lap my own valves but one trick I learned that made the job a lot faster and easier for cars was to use a cordless drill attached to the valve stems. I don't know how severe the pitting is since I can't really tell on my iPhone so I can't say.

[BrokenSprocketGarage]

Those pits are unacceptable. You need to lap for a little longer or the valve seats need to be cut and the valves ground. The whole purpose of lapping a valve is for a completely clean smooth seal. Do it right while it is apart. If you send this to a machine shop you should also price out a larger intake valve job.

[wompin]

Wow that sucks. What affect does this type of pitting have? The bike was running like a cherry for the last 15000 miles. . .

Im gonna try lapping them a bit longer. If I sent the heads to a machine shop I think my wife will cut my balls off in my sleep (aka Im broke from buying diapers)

[junkyardxl]

I had a set of heads done, 3 angled and everything and it was pretty cheap actually. I'd just lap them longer if I were you.

[wompin]

mmmmkay

What is pretty cheap if you dont mind me askin? Im a pretty cheap guy so I might be able to swing it.

In the mean time Im gonna lap em a bit and try not to eat away the whole face. Updates in an hour or so...

[BrokenSprocketGarage]

Yup, lap your balls off! Ha, either lap your balls off or send heads to a machine shop and your wife will cut your balls off. End result either way is ball-less Wompin

I think it was like 100 bucks here in nc.

That also included decking and the valve works and vat cleaning
