Best of the late sweetish big bores for everyday use ?

Thanks Surprize,
My manual states 2.2mm BTDC, I am running 1.8mm, may retard a little more.
I thought leaning the needle would make it worse?
Muffler has a very large bore, freshly packed with proper packing, my experience with steel wool is that it will burn and throw sparks unless stainless steel wool is used.

no if your rich on the needle, the motor hesitates (loses power due to poor carbying) then as it comes onto the main jet, it cleans up and you get a rush of power. worth dropping the needle to see how it responds....never seen a twoie send sparks... fourbangers yes..speccy a tnite

I'll try dropping the needle, but it actually felt a little lean coming onto the needle originally with this pipe, a play with the air screw stopped the run on at trailing throttle.
One thing I don't want to do is lean sieze it.


Many years ago I repacked my IT490 muffler with ordinary steel wool, and while not a light show, you could clearly see the red flecks coming from the (stock) exhaust, maybe not a good thing in the summer!

I really like the stock pipe power delivery but my header is beat up on my stock pipe, does anyone know if a header from a different bike, maybe centre port YZ490 header could be mated to the Husky pipe?
Tony.

I would suggest if your going to run a big bore a compression release would be handy. Sometimes by the middle of the ride to the end of the ride I could just about put the bike on the trailer. I was logging and in my prime back then. Just a thought.

If it were hard to start or I experienced kickback, I'd consider that Bill, what makes you suggest a decompressor for a bike that starts easily?
Tony.

Me personally I have a hard time starting bigger bores years ago. I welded in a sleeve in the head of my '86/400 and installed a compression release. I could start it no problem. In time the wear on my joints became worse as I get older.

smoke everybody !

I could have brought the pipe down here and ol mate "Mr Exhaust man" could have rebuilt the header for you no probs. would cost a cupla hunerd bucks probly but he does good work. he cleaned my pipe up nicely.

I should have thought of that! Does he just repair the header or can he replace sections? Mine has been welded poorly in the past.
Tony.

My apologies silverstreatNZ for the thread hijack, I'll start a new topic.

Tony.

he makes full new pipes for Mick down here, so he can make repair anything. could use my bike for a template if required, I think they are the same in the frame pipe dept

Thanks JC, that's good to know. I think I'll just send the pipe to him. Do you have contact details?

On second thought, that's probably a good idea if mine has been bent out of shape, I'll call you to discuss it.
