Ready To Reassemble!

[SonOfSand]

Hey Guys, I just got my new crank, ported cylinders, and case back from HJR. Is there anything I should lookout for, or be aware of when reassembling the cases? I have read the section in the Clymer manual, but wanted to ask the guys who do this all the time.

 

Thanks.

Quick question guys, I just installed my cylinders, and used a little permatex ultimate grey on top of the base gasket. Do I need to let the engine sit for 24 hours before I can ride it?

 

Thanks.

Pay attention while you are assymbling it and do a engine leak down test when it is together.

GREAT advise. I learned the hard and costly way.

Thanks guys, why is the leakdown so important? If I have an airleak, wont it show up in the idle?

 

Also, just started it and found out I am leaking coolant from my noss cool head, is there a good place to get the O-rings for cheap?

No it wont for sure. A small leak may not be noticable at idle but fatal at WOT. Its your bike do as you want but I leak test everytime I break it down.

There's a ton of places that sell the o-ring kits. Try to purchase local or from somewhere in your region, so you don't have to wait more than 1-2 days.

 

I also torque the cool heads down to 22ft lbs too. I've had mine dribble coolant at 20ft lbs.

Unless you want to do a back-to-back rebuild , I would suggest you do a leakdown test. Learning the hard way isn't fun!

100X yes on the leak down test.

I bought a leak down tester from RB Porting in MI. I've sold several of them for him to members.

I've saved a few motors already by letting buddies borrow it.

 

It could show at idle, it could do real funny things at high RPMs (not where you want to diagnose a problem).

You can make your own or spend 50 bucks for the one I got.

 

Three basic things every motor should have done before they are ever fired:

 

Leak down test first

Squish test next

Compression test cold.

 

If any of those are off, you just saved yourself a lot of headaches and more so money!

I wanted to thank everyone for their input, I didn't understand the importance of a leak down test, now I do. I will do it before I ride. Thanks.

It's great to have someone actually listen to others input and grasp the importance of some things,For that I salute you and it may save you abit of money also.Not sure if you already installed the clutch cover and installed the stator and flywheel but Every one I build for myself or customers I leave that stuff off when I do the leak down test it makes it alot easier to check the crank seals and drive gear key for leaks as well.

Hey guys, will pro design o-rings work on a noss cool head?

They sure will.
