390xp

Too each their own, I would never do it that way. especially on Husky cylinder where the bottom protrudes into the case, I've seen people cut holes in wood that the cylinder fits in and put sand paper around the hole and sand away. Sorry but I like things accurate.



Don't know. Was thinking of leaving it alone and see how it runs, ex will stay the same for sure, if anything the intake can come down a little, and transfers up 2°, but its so close now, I may just leave it and try it, just widen all the ports though.

It's accurate enough, I've done it twice and it took me 5 hours each time. :eek2:

I don't have enough patience.

Are you talking about a wooden mandrel, or something else Will? Im trying to envision it, but ......:msp_confused:

 

[mdavlee]

Cut a hole in a piece of wood or tile or something like that where the piece that protrudes down into the base will slide down in and sand paper can be mounted down.

or in the case for you and durand you can make a short trip to your buddies saw shop and have him do it while you wait. much more precise than doing it by hand. lol

 

[komatsuvarna]

Oh OK, Youns talking about the base, not the chamber. Iz lost for a minute....again lol.

Terry, That piston made almost 190 psi lol.

 

[NORMZILLA44]

How's it coming along Will?

itll hit over 200 when the rings seal. no need for the ring polishing for more compression huh

MEH, been sick for the past few days. All I've done is think about it.

 

[NORMZILLA44]

Sorry to hear that, and that sh## is going around here too! I know I would be the same way, that saw would be the only thing on my mind!

Ya it sucks. Had it planned for my kids to go spend the night at my parents on New Years Eve, so me and the good wife could go do something, they still went, all I did was lay on the couch feeling sorry for myself. I had 0 energy today, actually right now I'm feeling a little better, still all stuffed up though.

I'm fighting my second cold already. The first one only lasted about a month!

 

[NORMZILLA44]

Just shook one off this weekend, felt it coming on so I took ziacam that stuff work's wonders.

 

[husq2100]

................. Anyway I am over boring and honing a 390 55mm cylinder to 56mm raising the combustion chamber as much as I can and I am going to try and use a 2100 thin ring piston..............

I doubt this is going to work for you...you will have to remove all the Nikasal to get it to 56mm and then all you have is aluminium....no good for running a cylinder on. Only way to do it is to over bore it and have it replated like the race guys do.

Zicam. It's a nasal spray with Zinc in it. It's supposed to ward off colds when you feel one coming on.
It's thought that the Zinc breaks the peptide bonds so that the Rhinovirus can't get established.

HUU, never heard of it. Sounds interesting. Wonder if I can buy it here in Canuckastan.

Zinc lozenges will help after a cold is established. I think you want the ones with vitamin C and magnesium.
